Crops in silico project
As the Earth’s population climbs toward 9 billion by 2050 — and the world climate continues to change, affecting temperatures, weather patterns, water supply, and even the seasons — future food security has become a grand world challenge. Accurate prediction of how food crops react to climate change will play a critical role in ensuring food security.
An ability to computationally mimic the growth, development and response of crops to the environment will allow researchers to conduct many more experiments than can realistically be achieved in the field. Designing more sustainable crops to increase productivity depends on complex interactions between genetics, environment, and ecosystem. Therefore, creation of an in silico — computer simulation — platform that can link models across different biological scales, from cell to ecosystem level, has the potential to provide more accurate simulations of plant response to the environment than any single model could alone.
As a leader in plant biology, crop sciences and computer science, Illinois is uniquely positioned to head this initiative. Developments in high-performance computing, open-source version-controlled software, advanced visualization tools, and functional knowledge of plants make achieving the concept realistic. The interdisciplinary Crops in silico (Csi) team will take advantage of resources in the National Center for Supercomputing Applications (NCSA) and the Institute for Sustainability, Energy, and Environment (iSEE) — and its academic and research expertise in plant biology, crop sciences, and bioengineering — to build a user-friendly platform for plant scientists around the globe who are working on the food security challenge.
The 2017 Crops in silico Symposium & Workshop is set for June 26-28 at the University of Oxford, UK. This second annual gathering is for experts in experimentation, agronomy, physiology, plant development, phenotyping, as well as experts in computational modeling, software development, and data visualization. The event aims to harness the great strides in understanding of plant function from genes to whole plants, to accelerate forward approaches to crop breeding and bioengineering.

The 2016 Psi Symposium & Workshop — which brought together local, national, and international experts to exchange information and collaborate on a course for achieving crops in silico — was May 18-20 at the National Center for Supercomputer Applications (NCSA) on the Urbana-Champaign campus of the University of Illinois. It featured presentations by leading experts in modeling plant processes, top scientists in achieving in silico representation of other organisms, and computational scientists.
iSEE, NCSA, and the Crops in silico team are grateful for a generous gift from the Olga G. Nalbandov Lecture Fund, which helped to make this event possible. Other contributors: the Carl R. Woese Institute for Genomic Biology (IGB); the College of Agricultural, Consumer and Environmental Sciences (ACES); the Department of Crop Sciences; the School of Molecular and Cellular Biology (MCB); the Department of Plant Biology; and the Genomic Ecology of Global Change Theme at IGB.
In the past year, some technical developments …
- Csi has developed multiple models:
- a molecular model of At1, a key nitrate transporter;
- a gene-level model of the effects of changing nitrate uptake rate and cellular concentrations on transcript and metabolite levels;
- a gene-level model of the effects of changing atmospheric carbon dioxide concentrations on transcript and metabolite levels;
- a metabolic model that simulates the processes of photosynthesis under elevated atmospheric CO2 concentrations;
- a system-level model that simulates carbon partitioning between the leaf and roots, and sugar-starch portioning under elevated atmospheric CO2 concentrations;
- a solar light absorption model using bi-directional path tracing.
- Csi has rendered plant- and canopy- level data derived from the system model and measured field data of soybean over the course of a growing season. This data includes phenotypic differences between soybean growing under ambient and elevated atmospheric CO2.
- Csi constructed a run-time communications system for integration. The system provides global control, logging, and debugging support and permits new models to be integrated without requiring change to existing models. The metabolic and bio-system models are on line, with others being added as they become ready for testing.
