Sivaguru, University of Illinois at Urbana-Champaign
Alvaro Godinez, Becton Dickson and Company

There are several advances made in flow cytometry in recent years, including new sorting techniques using DEP. And the development of microfluidic devices.  Some examples of modern flow cytometry methods for cell sorting include Label-free sorting, Mass cytometry, and Image stream cytometry. We will show case Image stream cytometry that combines the speed and sensitivity of flow cytometry with the ability to capture high-resolution images of individual cells. These images can be used to analyze the cells in greater detail and to identify specific features or structures within the cells. In addition, image stream cytometry is a powerful tool for cell analysis, as it allows researchers to combine the quantitative data provided by flow cytometry with the visual information provided by microscopy. It can be used to study a wide range of cell types and phenomena, including cell signaling, cell migration, and cell-cell interactions. Image stream cytometry is also well suited for high-throughput cell analysis, as it can process thousands of cells per second and generate a large amount of data in a short amount of time. Experts in the modern flow cytometry will be presenting and available to discuss on various cytometers including Amnis® ImageStream® cytometery, and Microfluidic devices and its advantages over traditional cytometer.

PLANT SYMPOSIUM

Fostering Crop Resilience through Biotech, Breeding, Sensory Biology to Adapt to Changing Ecosystems

Conveners: Heqiang `Alfred` Huo, University of Florida, Huixia Wu, Ball Helix, Christopher Bagley, Inari, and Veena Veena, Donald Danforth Plant Science Center

Speakers:
Engineering Plant Vascular Tissues for Yield, Nutrient, and Stress Improvement
Cankui Zhang, Purdue University
Cytogenetic Manipulation and Enhancement of Crop’s Adaptation to Environmental Changes
Jiping Zhao, Ball Horticultural Company
Towards Robust Crops Under Environmental Adversities
Hong Luo, Clemson University

Extreme climate variations happen more frequently due to climate change, and agriculture faces these enormously fluctuating conditions accompanied by unpredictable abiotic and biotic stresses. The unfavorable environments and dwindling resources such as farmland and gene pools because of the ever-increasing global population and rapid urbanization are one of the most difficult challenges of this century. Classical breeding approaches such as hybridization breeding and mutation breeding have been extensively used for developing climate-resilient crops. At the same time, there have been many successful attempts to improve crop resilience through advanced biotechnology techniques and molecular genetics approaches. This session aims to update the research progress on the application of various biotechnology strategies to improve the stress-resilience of crops; the presentation topics will cover the basic understanding of the mechanism underlying the responses to environmental stresses (temperature, light, drought and salinity etc.) and practical application of novel technologies for improving plant performance in the changing environments.

ANIMAL SYMPOSIUM

Organoid Modeling of Complex Systems: From Novel to Necessity*

Conveners: Michael K. Dame, University of Michigan Medical School, and Durga Attili, University of Michigan Medical School

Speakers:
Generation of Regionally Defined Brain Organoids

Pig Outside a Pig – Disease Modelling and Welfare
Matheus Costa
, University of Saskatchewan
A Cell Atlas of the Pediatric Human Lung Aligns In Vitro Differentiation Strategies to Human Lung Development
Tristan Frum
, University of Michigan Medical School

Organoids provide an invaluable tool to explore organ-specific, and importantly, species-specific questions. This is due to their ability to self-organize and accurately recapitulate defining tissue phenotypes. Further, organoids can now be directed to preserve region-specific characteristics of an organ system, via preservation of the source tissue or through directed differentiation. This model has become an essential translational tool to understand both basic biology and disease, having important implications not only in human but also in the welfare of agricultural livestock. This session will share exciting insights into three diverse systems: human brain, microbiota-host interactions in pig intestine, and human pediatric lung development.

PLANT SYMPOSIUM

Strategic Crops for Food Security in Underserved Regions

Conveners: Todd Jones, Corteva Agriculture, and Brigitte Weston, Gates Ag One

Several consequences of climate change are unpredictable weather patterns, extremes in temperature and inconsistent rainfall. These conditions create stress on food production systems and require adaptation to provide the necessary food and fiber for an ever-growing population.  One strategy to address the challenges of climate change is to increase crop diversity to improve the resiliency of food systems in these regions. This session will explore the current state of enabling technologies for crop improvement in under-utilized food crop species in regions most impacted by climate change, Sub Saharan Africa and South Asia.  Speakers will focus on strategic crops for food security in these regions such as: cassava, tef, cowpea, mung bean, yams, banana, ground nuts, pearl millet, potatoes and sorghum.  Speakers will discuss current capabilities, identify technology gaps and explore future opportunities for improving the impact of these under-utilized food crops.

EDUCATION WORKSHOP

Effectively Communicating Research to the Non-Scientific Community

Conveners: Jasmyn M. Hoeger, University of Iowa, and Christina Yevtushenko, McGill University

It is clear that people want to learn about science, but when research articles are filled with jargon and acronyms, it can be easy to get lost in an unwelcoming vocabulary that seems to require experience in a niche subject. Breaking down the hurdles to better communicate science to the non-scientific community has an important and powerful role: empowering, encouraging, and educating. How can scientists make their work as clear as possible? How can a bigger audience be reached? How can a message be accurately conveyed? This year’s student luncheon speaker from Virginia Tech’s Center for Communicating Science will shine light on common mistakes scientists make when writing a paper for a broad audience. Learn how to strengthen communication skills, simplify without losing information, and write outside the mindset of a scientist.

PLANT SYMPOSIUM

Innovative Approaches for Plant Gene & Editing Delivery*

Conveners: Matthew R. Willmann, Pairwise, and Raj Deepika Chauhan, Pairwise

Speakers:
Combining Multi-Omics Integration and Genome Editing in Forest Trees for Sustainable Fiber and Bioenergy Production
Jack Wang
, North Carolina State University
Viral Approaches for Overcoming Reagent Delivery Bottlenecks in Plant Genome Editing
Zhenghe Li, Zhejiang University
CRISPR-edited Plants by Grafting
Frank Machin, The University of Edinburgh
Wusheng Liu, North Carolina State University

Making transgenic and gene-edited plants typically involves delivery of DNA to cells using one of three standard methods—Agrobacterium, particle bombardment, or protoplast permeabilization—followed by selection and regeneration of stable transgenics in tissue culture to yield full plants with shoots and roots. As good as these approaches can be, researchers continue to work to develop alternative DNA-delivery methods to improve transformation efficiencies, eliminate or reduce the need for tissue culture, and/or allow for genotype-independent transformation. The advent of gene editing has also created a need for novel delivery methods, particularly for clonally propagated plants, that enable transgene-free editing. In this session, the invited speakers will share their experiences developing innovative approaches for gene and editing tool delivery to plant cells. The topics covered include DNA-free delivery of CRISPR editing tools to protoplasts or pollen using ribonucleoprotein complexes (RNPs), RNA-based delivery of Cas and gRNAs using plant RNA viruses, and delivery of editing reagents using mobile RNAs and grafting.

Invertebrate cell cultures serve as invaluable tools in pharmaceutical, environmental and agricultural research programs, including in the development of highly beneficial products.  Marine invertebrate cell cultures are intimately involved in the discovery and isolation of unique medical components, as well as provide insights into ecological disturbances.  Insect cell cultures play an effective role in insecticide discovery programs in both screening assays and mode of action studies. In all cases, in vitro methodologies are constantly being upgraded to enhance the performance of these cell culture-based assays.  Our symposium will highlight some of the state-of-the-art methodologies involved in these advances, including 3D cell culture, single cell sequencing and other related molecular techniques. In the marine biology arena, one speaker will highlight how advances in sponge cell biotechnology are leading to the development of novel drugs.  Another presenter will outline the harnessing of invertebrate cells in ecotoxicity studies to determine the impact of specific pollutants on the marine ecosystem.  For the agricultural focus, our speakers will discuss the use of primary cultures from insect digestive tissues as model systems for both targeting insecticides as well understanding basic invertebrate biology.  We will follow up the presentations with a panel discussion to better integrate and synthesize the ideas brought forward by our speakers, as well as to broaden the scope of application and summarize key points.

Plant Metabolomics

Convener: Qingchun Shi, Pairwise

Speakers:
Fredy Altpeter, University of Florida
Nishanth Tharayil, Clemson University
Swathi Nadakuduti, University of Florida

Metabolomics is a great systemic approach to understand plant indigenous chemical status as well as the interaction with its environment. Being natural factories of chemical compounds, plants possess invaluable metabolism creating chemicals for human food, biofuel, and pharmaceutical uses. Dissection of these metabolic pathways not only help us to understand how plants became specialized in compound production, but sheds light on ways for scientists to engineer metabolic pathways to boost or enable the beneficial chemical production in plants. In response to environmental cues, plants employ an arsenal of compounds to help them adapt to biotic and abiotic stresses, interact with other organisms, and balance resources between development and defenses. This gains us insight on why plants are resilient to different environments and what contributes to a harmonious ecosystem allowing more sustainable agricultural production. As precise genome engineering tools such as CRISPR-Cas being readily accessible and versatile, the expansion of metabolic engineering research results in more productive plants for chemical and more resilient species for the changing environment. In return, efficient genome engineering requires to solve several bottlenecks such as plant regeneration and transformation steps of recalcitrant species, and plant metabolomics could potentially provide novel solutions.

Brian Martinell, University of Wisconsin-Madison

Production tissue culture labs utilize the basic principles of micropropagation and transformation, but on a large scale to rapidly create large number plantlets with elite traits for the forestry, ornamental, and agricultural industries. The knowledge and protocols developed at the research level don’t always translate to large scale production and often must be optimized accordingly. Considering the complexity of simultaneously handling multiple genotypes/traits, tight production schedule, and repetitive nature of operation, special care is required to ensure smooth and successful production to fulfill customer orders. In this session, we will hear from tissue culture experts in both academia and industry on approaches to ensure the success of a production lab, including production scheduling, protocol optimization, process automation, data storage and inventory tracking.

Designing In Vitro Assays That Are Predictive of In Vivo Activity: A Focus on Development of Prediction Models*

Conveners: John W. Harbell, JHarbell Consulting, and Addy Alt-Holland, Tufts University Student Convener: Jasmyn M. Hoeger, University of Iowa

Speaker:
Prerequisites for Creating A Functional Prediction Model for A New Approach Methodology (NAM)
John W. Harbell, JHarbell Consulting
In Vitro Test Method Development: Starting With the End User in Mind
David Allen, Inotiv

Over the past several decades, there has been a marked increase in the number and complexity of cell and tissue-based bioassays being applied to a wide range of regulatory, developmental and safety applications. Examples include the federal agencies move to adverse outcome pathways in cultured human cells, 3D human tissue constructs and human iPSC-derived cell and tissue model systems. The protocols range from simple cytotoxicity assays to more refined systems for the prediction of hazard to complex systems that incorporate exposure kinetics and endpoint-specific measures to address risk. In this context, risk is defined as the demonstrated potential for an adverse outcome from an exposure. In vitro mutagenicity assays might be seen as predictors of hazard, rather than risk, since in vivo exposure is not modeled. Tissue construct models for predicting skin or eye irritation do incorporate exposure kinetics and so hold the promise of predicting risk (i.e., degree of irritation). This symposium will focus on test methods that are designed to predict hazard or risk, highlighting test guidelines falling under the Organization of Economic Cooperation and Development (OECD) international program. Particular emphasis will be placed on the development of quantitative predictions models that are used to translate the in vitro results into an in vivo prediction of hazard or risk. The prediction model is a key element in assay validation, and is predicated on establishing the reproducibility of the assay over time. Additionally, the test systems and assay endpoints should have mechanistic relevance in vivo. The discussion will include the importance of the prediction models developed with reference chemicals of known activity in vivo and the use of representative reference chemicals from different chemical classes and physical forms (solid/liquid) will be discussed. Presentations will address the historical drivers for the development of “modern” prediction models and real world experiences in building assay systems and resulting prediction models for regulatory applications.

Novel Transformation Technologies

Conveners: Yurong Chen, Bayer U. S. – Crop Science, Heidi F. Kaeppler, University of Wisconsin, and M. Annie Saltarikos, Bayer U. S. – Crop Science

Speakers:
Ashok Shrawat, Bayer Crop Science
Frank McFarland, University of Wisconsin
Heng Zhong, Syngenta

Since the first demonstration of successful plant transformation in mid 1980s, significant improvement has been made in the development of transformation technologies. In addition to numerous cell biology innovations and process optimizations made over the past forty years, the evolution of transformation target explants from suspension cultures, to callus cultures, to immature embryos played a critical role in terms of efficiency, throughput, germplasm flexibility and feasibility for automation. However, as genome engineering and editing applications are becoming increasingly complex, trait integration and deployment costs have greatly increased, becoming prohibitive in many cases. Development and optimization of simplified, genotype-flexible transformation/editing systems continues to be a critical means to meet complex plant transformation/editing needs in the future. This session will focus on the development of novel transformation technologies using mature seed embryo as explants, expression of developmental genes and in planta systems to address these issues.

Frontiers in Spatial and Single Cell Genomics*

Conveners: William Gordon-Kamm, Corteva Agriscience, Todd Jones, Corteva Agriscience, and Debora Esposito, North Carolina State University

Working with cell/tissue cultures within a tightly controlled environment sounds simple. However, as every in vitro biologist knows, growth and morphogenic responses are complex, making genetic and/or epigenetic studies difficult to interpret. As an adjunct to whole tissue RNA sequencing analysis, single-cell RNA-sequencing and spatial transcriptomics technologies enable the study of high-resolution transcriptional activity as an aide in illuminating patterns otherwise masked by whole-tissue complexity. Such techniques have been pioneered in mammalian research but are increasingly being used effectively in plant research. Examples of single-cell and spatial transcriptome analysis will be provided illustrating the advantages of increased spatial resolution in understanding gene expression.

Biotransformations are chemical reactions catalyzed by cells, organs, or enzymes and represent an area of biotechnology that has received considerable attention. The use of biotransformation with in vitro plant cell culture and open cell systems has immense potential to produce compounds with a commercial interest and pathway engineering, especially considering the vast biochemical capability for producing secondary metabolites from plant sources. This symposium will highlight the application of different plant cells culture systems, such as intact cell suspensions and open cell suspension, enabling the systems in vitro for advanced applications.

PLANT SYMPOSIUM

New Breeding Technologies and Traditional Technologies for Woody Species/Horticultural/ Ornamental Species*

Conveners: Jon Mahoney, Ball Horticultural Company, and Anthony Nwangwu, Duarte Nursery

Speakers:
Chris Dardick, USDA
Traditional Cell Biology Techniques for Ornamental Crop Improvement
Jiping Zhao, Ball Horticultural Company
Biotechnology of Woody Ornamental Plants
Hui Duan, USDA

Improvement of ornamental and horticultural crops by traditional plant breeding techniques has several limitations mainly caused by their high degree of heterozygosity, the length of their juvenile phase, incompatibility, and adaptation to the changing climate. On the other hand, crop improvement by new breeding technologies employs precision breeding tools and techniques to overcome some of the challenges encountered by traditional breeding. It’s now possible to precisely make gene specific modifications to express or suppress desired and undesired traits in a record time. This session will explore the impact of both traditional and emerging breeding technologies on accelerating breeding of woody, horticultural and ornamental species of commercial interest. Guest speakers with years of experience in content and practice of breeding technologies will share their experiences and address any question(s) from the audience during the session.
