Invertebrate and fish cell culture systems serve as valuable tools for the development and production of agricultural and biomedical products, as well as the screening of environmental contaminants. This symposium will focus on emerging technologies that are applicable in both research settings and industrial processes. Cellular agriculture is a rapidly growing area of advancement that involves the implementation of in vitro systems in place of whole plants or animals to produce agricultural products. A variety of these systems and potential products will be explored. We will examine the benefits of aquaculture, including the practical potential of selected marine products. The establishment of marine invertebrate cell cultures, which are linked to the discovery and development of novel pharmaceutical compounds, will be examined. We will review the use of fish cell lines to accurately assess the impact of potential toxins on the aquatic environment. Novel pest management strategies for field crops will also be investigated. The cloning of insect RNA viruses via cell lines will be outlined as a tool to generate more effective biological control agents. We will consider the use of cell cultures to optimize dsRNA uptake to increase the potency of RNAi-based insecticides. State-of-the art molecular approaches important to the development of novel cell culture systems for biomedical and agricultural research will be reviewed. We will end with a roundtable discussion to synthesize/summarize the ideas brought forward and discuss how these new technologies will point towards a future that will support the development of sustainable agriculture, improved stewardship of our environment (including the oceans), and enhanced systems for biomedical discoveries.

Marine Invertebrate Cell Models: Applications and Implications for Research

Convener: Shirley A. Pomponi, Harbor Branch Oceanographic Institute – Florida Atlantic University

Speakers:
Evolution and Developmental Biology
Scott Nichols, University of Denver
Cnidarian Symbioses
Stephanie Barnay-Verdier, Sorbonne Universite

Marine Invertebrate Stem Cells
Baruch Rinkevich, Israel National Institute of Oceanography

 

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture, and toxicology. Although cell lines have been established from freshwater invertebrates (e.g., Hydra), attempts to establish cell lines from marine invertebrates have been unsuccessful until recently, when nutrient medium optimization resulted in the establishment of cell lines from several marine sponges.  Most research on marine invertebrate cells has been conducted on primary cultures.    This session will focus on three research areas using marine invertebrate cell models: evolutionary and developmental biology, symbiosis, and adult stem cell research. Sponges are ideal models to study animal evolution: they evolved hundreds of millions of years ago, and despite their simple body plan, they share many genes and molecular pathways with more structurally complex animals—including humans.  We will review recent research using sponge cells to elucidate the molecular foundations of early animal evolution and development.    Recent advances in understanding cellular mechanisms of marine invertebrate symbioses, particularly sponge-microbe and cnidarian-dinoflagellate, will also be reviewed.   Adult stem cells in multicellular organisms are crucial for tissue homeostasis, repair and regeneration. Although the properties of stem cells are well studied in vertebrate and terrestrial invertebrate models, very little is known about marine invertebrate adult stem cells (MISCs). MISCs are key participants in many unique processes that occur in marine organisms.  Research in progress on MISCs, particularly in tunicates, will be addressed.   The session will conclude with a panel discussion to summarize and synthesize the research presented, and to discuss applications of the technologies to address issues of societal importance, e.g., human health (including better understanding of disease processes, and discovery and development of novel pharmaceuticals), habitat restoration, and effects of climate change.

Plant gene editing has been harnessed as a new research tool for reverse genetics as well as a new breeding tool to advance agriculture. Thanks to immense interest and investment in the field, the CRISPR-Cas gene editing toolbox is under rapid evolution with constant addition of new tools, from novel Cas nucleases to base editors and prime editors. These new tools have greatly benefited gene editing in plants. However, successful implementation of these tools depends on many variables, including design of the guide RNA, means for in planta guide RNA processing, method of delivery (e.g. Agrobacterium, biolistic, virus, nanoparticles etc.), promoters of choice for the Cas and guide RNA, codon and nuclear localization signal (NLS) optimization for the Cas, strategies for multiplexed editing, temperature regime, etc. In this session, invited speakers will present recent advances relevant to these aspects. The information will give the audience and users a timely update on the state-of-the-art of these exciting tools and how to best utilize them for specific precise gene editing outcomes in plants.

Genetic Improvement of Potato Using Innate® and GE Technology in a Challenging Landscape
Jeffrey Habig, J. R. Simplot Company
Consumers Attitudes Toward Gene Editing
Brandon R. McFadden, University of Delaware

To date, advances in agricultural biotechnology via Ag biotechnology / genetic engineering (GE) predominantly have focused on improving Agronomic traits.  Most successes with developing products targeting consumers using GE platform have been limited to few examples viz high Oleic acid soy, non-browning apples and potatoes and omega-3 enriched soy.  Although, consumer awareness of GE platform seems to have increased over the last decade, however, the acceptance of food derived using GE platform has been painfully slow.  Today we are surrounded by consumers living in an era where introduction of “fast products” and “constant disruptions” of the marketplace with new products are a new norm.  In these changing times, what is crucial for Ag biotech industry is to reinvent itself for delivering products faster – based on innovation, speed to market with agility / rapid scale-up provisions and addressing consumer sentiments at a continuous pace. Product development via gene editing offers advantages for speed breeding by bypassing conventional long process of bringing products to the marketplace. This session will cover new tools relating to speed to market and consumer acceptance related issues.

Utilization of biological approaches is greatly expanded into a rapidly growing interdisciplinary area that incorporates engineering principles. This has included design-build-test cycles to synthesize entire new biological organisms or parts. The ability to introduce complex multi-gene pathways into organisms has found many applications in plant biotechnology to generate novel, favorable phenotypes and for production of valuable molecules in plants (vaccines and biofuels are only a few examples). Gene editing and the manipulation of mammalian cellular membranes or tissues has opened up new avenues of research to understand cellular processes or the development of new therapeutic approaches. This session will focus on the use of various biological tools that have been used to manipulate plant and animal cells and organelles. The possibility to perform analysis on single cells and subcellular compartments like plastids in plant cells and membrane and subcellular compartments such as the mitochondria in mammalian cells has considerably expanded the potential for biotechnology applications. The session will also focus on various aspects of cell manipulation and precise metabolic engineering and how these advanced tools can be used to develop new products and approaches.

Application of Stem Cell Technology to the Development of Tissue-specific Organoids

Conveners: Daysha Ferrer-Torres, University of Michigan School of Medicine, and John W. Harbell, JHarbell Consulting, LLC
Student Convener: Evan M. Hill, University of Michigan School of Public Health

Michael J. Moore, Tulane University and AxoSim, Inc.
TBD
Nicholas Constantine Zachos, Johns Hopkins University

Three dimensional organoid constructs are a culmination of decades-long goal of in vitro cell biologists to produce quantities of functional organs for research and regenerative medicine. While the 2D monolayer systems contributed much to our understanding of cells in culture and serve many important areas of research, they also showed us the limitations of working with primary cultures which lack the organ-specific substrate, spatial arrangement, supporting cell types and specific hormone/growth factor milieu. Methods to isolate and expand cultures of tissue-specific stem cells lead to some of the early successful organoid constructs such as skin or intestine where exposure to the air-liquid interface provided an essential stimulus to epithelial differentiation. However there are many tissue types from which stem cell isolation have shown only limited success, and that are difficult to obtain (i.e., central nervous system, lung, and other non-tumor tissues). The world of tissue culture changed radically with the introduction of methods to produce iPSC (induced pluripotent stem cell) cultures from differentiated somatic cells. Creation of iPSCs was based on selectively inducing the expression of four transcription factors in the target cells. Subsequent refinement in the technology has eliminated the need for viral integrations which is a boon for use of these cells in regenerative medicine and interrogation of developmental biology. This symposium will focus on tissue-specific organoid constructs starting with the development of iPSC cells and progressing through the 3D construct and its application to research and potential for use in regenerative medicine.

They can be used to study disease modelling by genetically modifying them to reflect the disease conditions, test potential therapeutics, and develop personalized medicines. In this session, three speakers will be presenting data based on their diverse research using organoid systems. The first speaker uses organoid models to study intestinal stem cell (ISC) properties, demonstrating their self-renewing abilities and multipotency. The second speaker will discuss his use of mouse intestinal organoids to study the leucine-rich G protein-coupled receptor (LGR5) and its regulation via internalization and trafficking, hoping to learn more about LGR5 expression in various cancers. Finally, the third speaker will discuss her use of iPSC derived cerebral organoids to analyze gene expression patterns in bipolar disorder patients, implementing the organoid model to study a disease for which there is currently no good alternative cell line or animal model. The implications of these various organoid models are highly promising, and should advance our understanding in a wide variety of human diseases.

 

Recent Advances and Applications in Single-Cell Technologies

Abraham Lee, University of California-Irvine

The regulation of gene expression ultimately determines the type and function of cells and tissues of higher eukaryotic hierarchical architectural organization with the complexity from the single cells to the whole plant or animal. Due to a lack of technologies, past research often had to rely on measurements in bulk populations of cells within tissues to study gene expression, cell function, and tissue physiology. However, recent advances in single-cell technologies are becoming essential tools to unmask the heterogeneity of cell functions within a tissue. Until recently, most of our scientific knowledge generally stemmed from population data where we consider cells belonging to the same subtype as a single unit where the members that compose the class are, by definition, homogeneous and identical. This concept represents an extreme simplification of reality, which can be attributed both to the necessary simplification required to understand the global picture and also to the lack of past technologies and data analysis techniques that allow more granular investigations. The lack of technologies for studying single cells has had the most significant impact on the analysis of cells that occur as a minimal fraction of the initial population: such as stem cells. Recent advances in single-cell technologies are now allowing the study of single cells or cell types for different phenotypic markers simultaneously. In plants, individual gametophytic cells are reprogramed to produce haploid embryoids that can be doubled to generate di-haploids. This technology has helped plant breeders accelerate improving many of the food crops. In the recent past, the protoplast system enabled the plant biologist to edit to generate new clonal lines of commercial value by domesticating a few underexploited crops. In mammalian systems, these new single-cell technologies are transforming our fundamental understanding of how individual cells play unique roles within the tissue and is heralding many breakthroughs in the area of human health. In this session, we will showcase a few examples of single-cell techniques powering fundamental research on the cell heterogeneity of tissues and the application with the analytical power to create value to the scientific community.

Characterizing Novel BRD4-dependent Nuclear Proteins in the Heart
Matthew Stratton, The Ohio State University
Regulation of Genome Stability by Histone Variants
Yannick Jacob, Yale University
Epigenetic Regulatory Mechanisms Associated with Neural Cell Specification
Hehuang Xie, Virginia Tech

The term epigenetics is used to refer to the heritable changes in gene expression due to epigenetic modifications such as DNA methylation, altered chromatin structure, RNA based mechanisms, altered DNA accessibility and histone modification. Epigenetic change can be caused by a variety of factors especially environmental stimuli in response to stress. In plants and animals, epigenetic mechanisms play a key role in the regulation of the stress response, adaptation, disease, senescence and other processes. It is important to understand the factors and the mechanisms that causes these changes in order to eliminate deleterious effects of epigenetics. Deeper insights and recent advances in understanding mechanisms of epigenetics and its implications in both plants and animals will be presented in this session.

Quality might be considered the overarching principle of in vitro research and commercial plant production. Quality has many definitions that depends on the specific situation and objectives. For research, quality largely means the production of new knowledge through experimentation. The design of experiments (DoE) is a system of principles and methods for conducting experimentation. For commercial plant production, quality encompasses all products, services, systems, and processes that affect a company’s stakeholders. Six Sigma are the principles and methods to improve any process and includes defining and quantifying the problem, and then measuring and analyzing to improve that process. The session will discuss some methods and quantitative tools used for experimentation, quality control, and process improvement that are relevant for in vitro research and commercial plant production.

Advances in Cannabis Regeneration Systems and Biotechnology

Conveners: Sadanand A. Dhekney, University of Maryland Eastern Shore, Hemant Lata, University of Mississippi
Student Convener: Tej Man Tamang, Kansas State University

Speaker:
Development of a Tissue Culture-based Agrobacterium-mediated Transformation System for Cannabis sativa L. (marijuana)
Zamir K. Punja, Simon Fraser University

Plant biotechnology has several applications in genetic improvement and cultivation of medicinal plants. The medicinal properties of Cannabis along with the diverse health and industrial applications for hemp have evoked significant interest among the general public and the scientific community. Genetic improvement of Cannabis and industrial hemp have been limited to breeding by private individuals and entities due to the federal restrictions imposed on these crops for a long time. The recent formulations of regulations for industrial hemp production along with state legislation permitting Cannabis production in certain states now makes it possible to apply techniques in plant biotechnology for crop improvement and enhancing production. Batch to batch consistency in useful secondary metabolite contents is utmost important for any biomass product of pharmaceutical interest. Cannabis is a dioecious and occasionally monoecious (hermaphrodite) plant, and therefore seed-derived plants make it challenging to maintain the chemical profile and cannabinoids content of produced biomass, especially when more several varieties are grown side by side. To avoid that, male plants are removed at the early flowering stage and vegetative cuttings of selected female plants are cultivated. Plant tissue culture is recognized as one of the key areas of plant biotechnology that plays a very important role in conservation and mass-propagation of valuable genetic resources. In this session, current developments on biotechnological approaches for Cannabis plant regeneration and future prospects for crop improvement will be discussed.

Novel Applications of Biosensors as Readouts for Environmental Monitoring and Improving Human Health

Conveners:  Kolla Kristjansdottir, Midwestern University, and Addy Alt-Holland, Tufts University 

Speakers:
Engineering a Fluorescent Biosensor for the Herbicide Glyphosate
Shahir S. Rizk, Indiana University South Bend
Atomic Force Microscopy Combined with Machine Learning as a New Approach to Detect Cell Abnormalities: Towards Outeromics
Igor Sokolov, Tufts University

Biosensors are analytical and innovative devices that are designed to unambiguously detect substances with exquisite sensitivity for the benefit of improving human health and environmental monitoring. These devices involve biological “sensing” elements, and can detect an incredible variety of analytes ranging from chemicals to proteins to microorganisms. Biosensors are routinely used in wide range of industries and applications for the benefit of improving human health and environmental monitoring. This includes the field of healthcare, biomedicine, diagnosis of infectious diseases, and drug discovery. Biosensors are implemented in monitoring of food processing, quality, safety and sustainability, as well as in different fermentation processes. Biosensors are applied in environmental monitoring, where they are used for rapid detection of pesticides and heavy metal pollution in order to prevent health hazards. Biosensors are applied in plant and marine biology, and they are critical component in biodefense and security applications for identification of bio-warfare agents of bacterial, viral and toxins origins. The method of analysis also varies widely and these devices can be divided into several categories based on their detection method and sensitivity. These include electrochemical biosensors, optical and fluorescent biosensors, silica, quartz and crystal biosensors, nanomaterials-based biosensors, and microbial biosensor technologies that are based on genetic engineering and synthetic biology. Our invited speakers in this session will focus on recent technological advances in biosensors and their applications in the diagnosis of infectious diseases and environmental monitoring.

Bottlenecks that thwart achieving efficient genetic engineering and gene editing approaches in plants can come at various stages including plant regeneration, transformation, and recovery of quality (low copy number, desirable phenotype) modified lines. With the advent of gene editing technologies, tailor-made genetic modifications to help advance crop improvement can be realized and has resulted in a demand more than ever before for reliable, robust genetic engineering pipelines. Efforts to develop these pipelines are underway by researchers in both the public and private sectors; however, progress is often slowed due to several factors such as access to germplasm, limited funding, and lack of resources that include infrastructure and experienced personnel. The purpose of this session is to explore possibilities for building connections within and between public and private research organizations. Through two presentations that will present overviews of the issues, a panel discussion, and audience participation we intend to establish a foundation that will help us move forward by identifying where the greatest needs are and how we can collaborate as a community to address them.

Novel Plant Transformation Technologies for Gene Editing Without the Integration of Transgene

Conveners: Shubha B. Subbarao, Bayer U.S. – Crop Science, and QingChun Shi, Pairwise

Speakers:
Somatic Transgene Excision Strategies for Gene Editing in Clonally Propagated Plants: Inducible Excision Performance in Transgenic Poplar
Steven H. Strauss, Oregon State University
DNA-free Editing in Corn and Soy
Ashok Shrawat, Bayer U. S. – Crop Science

Transgene-free transformation is an appealing strategy to introduce desired genetic change without the integration of unwanted foreign DNA. This is particularly relevant in plant species with economical or agricultural significance. It may save time for downstream procedures such as transgene removal via segregations and the costly screening effort. For clonally propagated plants where segregation-by-crossing is not feasible, integration-free transformation changes only targeted loci while preserving all other desired traits. In the era of gene editing, creation of deletion mutation (e.g. gene knockout) or point mutation (e.g. amino acid alternation by base editing) are often the outcome and these modifications assemble natural genetic exchanges or mutations by conventional breeding approaches. Hence gene edited plants can be arguably not subject to GMO regulation if integration-free transformation is used. This emerging area of research may include not only variants of Agrobacterium-mediated and biolistic transformation method, but novel delivery techniques such as by nanoparticles and ribonucleoproteins for non-integration gene editing. This session hopes to bring to its audience, the recent research progress on integration-free gene editing as well as the scope to implement the technologies in facilitating plant genome engineering. 

Scaling Up Cannabis Production

Convener: Max Jones, University of Guelph
Student Convener: Adrian Monthony, University of Guelph

Speakers:
Matthew R. Willmann, Cornell University
Ian Cole, Zenlabs
Jessica Lubell-Brand, University of Connecticut

With the legalization of recreational Cannabis sativa L. in Canada in 2018 and hemp following the passage of the 2019 Farm Bill, Cannabis tissue culture has entered a rapid growth spurt.  These early years have been characterized by growing pains, as research groups establish tissue culture protocols for the growth and maintenance of germplasm and begin looking towards the application of plant biotechnologies in the species.  Researchers looking to establish roots in the field are faced with a multitude of challenges:  Existing literature on the tissue culture of Cannabis is limited;  existing micropropagation protocols are not easily replicated between different cultivars or lab environments; the highly polytypic nature of the cannabis genome has made development of basic growth and multiplication protocols challenging; furthermore the in vitro growth requirements for drug-type and hemp-type Cannabis are divergent. This session will bring together experts from industry and academia, covering both hemp and drug type Cannabis and will provide a forum for them to share their experiences weeding out some of the common problems faced in the early stages of Cannabis tissue culture.  This session will cover the lifecycle of tissue culture from the early struggles maintaining germplasm and selecting the appropriate growth conditions to approaches needed to scale up in vitro Cannabis production.
