    MEETING RECAP 

    The Fourth Annual Crops in silico Symposium and Workshop was held May 1-3, 2019 at NCSA. The objective of the Symposium and Workshop was to identify how the Cis community can communicate and coordinate their research, training and educational activities. The Symposium had 60 registrants from 13 institutions.
    Graeme Hammer, Crop Science Professor and Director of the Centre for Crop Science in the Queensland Alliance for Agriculture and Food Innovation (QAAFI) kicked off the symposium on Wednesday, May 1st with his talk on Biological Reality and Parsimony in Crop Models – Why We Need Both in Crop Improvement!
    The first full day of the symposium began with Meagan Lang providing an update on the Current Status of the Crops in silico Framework. The Symposium had three themed speaking sessions: Structural Analysis, Genes to Crop Growth, and Development and Growth. Eight junior researchers gave short format “lightning talks” to present their research. Nine attendees presented research posters during the interactive poster session.
    The goal of workshop on the afternoon of May 2nd was to create new research collaborations. First, participants were asked to identify challenges to their research, then they were matched with collaborators. Participants met and committed to many new research collaborations during the meeting. Researchers presented their matches on the morning of May 3rd.
    Stephen Long concluded the activities on May 2nd with his presentation, Mathematically Guided Improvements of Photosynthetic Efficiency for Sustainable Increase in Crop Productivity.
    The goal of the Hackathon was to introduce and familiarize model scientists with the yggdrasil package and user interface. During hands-on examples, participants learned how to use the yggdrasil package and user interface to connect two models written in Python and C from package installation to model transformation and execution. Anyone interested in walking through the hackathon materials on their own can do so using the documentation on GitHub.

     

     

    ABOUT THE SYMPOSIUM, WORKSHOP & HACKATHON

    Symposium and Workshop: Expanding the Framework

    The Symposium will broadly highlight advancements in plant biology gained from modeling, big data collection and analysis, and computation. The goal of the Symposium is to explore the interests and needs of the plant and computer science communities for building virtual crops. The accompanying workshop provides an opportunity engagement and collaboration.

    Hackathon: Lowering the Barriers to Model Integration

    To build on the success of the Hackathon last year, we include another one that will further lower the barriers to collaborate on model integration within the Crops in silico community.
    The Hackathon will consist of short tutorials alternating with practical exercise that will guide participants through model integration using the Crops in silico framework, which enables communication, orchestration, and transformation.
    Computer programmers, software developers, interface designers and plant biologists will work side-by-side during this hands-on event. Only basic knowledge of coding and version control will be necessary.

    KEYNOTE SPEAKER


    Graeme Hammer

    Crop Science Professor and Director of the Centre for Crop Science in the Queensland Alliance for Agriculture and Food Innovation (QAAFI), University of Queensland, Australia
    Biological Reality and Parsimony in Crop Models – Why We Need Both in Crop Improvement!

    The potential to add significant value to the rapid advances in plant breeding technologies associated with statistical whole genome prediction methods is a new frontier for crop physiology and modelling. Yield advance by genetic improvement continues to require prediction of phenotype based on genotype, and this remains challenging for complex traits despite recent advances in genotyping and phenotyping. Crop models that capture physiological knowledge and can robustly predict phenotypic consequences of genotype-by-environment-by-management (G*E*M) interactions have demonstrated potential as an integrating tool. But does this biological reality come with a degree of complexity that restricts applicability in crop improvement? Simple, high speed, parsimonious models are required for dealing with the thousands of genotypes and environment combinations in modern breeding programs. In contrast, it is often considered that greater model complexity is needed to evaluate potential of putative variation in specific traits in target environments as knowledge on their underpinning biology advances. Is this a contradiction leading to divergent futures? Here it is argued that biological reality and parsimony do not need to be separable. It is further asserted that the structure needed for the next generation of crop models to be most effective perhaps requires both jointly, along with the capacity to evolve in crop growth and development process algorithms. Specific examples in modelling photosynthesis from biochemical scale and canopy development from plant scale are used to highlight the concepts presented.

    Hammer conducts research on the physiology and genetics of complex adaptive traits in field crops with a focus on water productivity in cereals. His research underpins the development of mathematical models of crop growth, development and yield that enable simulation of consequences of genetic and management manipulation of crops in specific target environments. His research approach provides unique opportunities to aid crop management and design for enhanced production in water-limited environments; enhance the utility of molecular breeding for drought adaptation; and identify avenues to cope with climate risks in field crop production. He is a Fellow of the Australian Agriculture Institute and was awarded the Australian Medal for Agricultural Science in 2013 and Farrer Memorial Medal in 2012.

    LODGING

    Attendees must arrange their own lodging. There is a block of rooms at the Hampton Inn under “Crops in silico” but plenty of other places to stay in the Champaign-Urbana area. However, you will need to secure your own transportation to and from the meeting.
