RII Track-2 FEC: Genome Engineering to Sustain Crop Improvement (GETSCI)

Improved and practical crop breeding tools are required to meet the increasing demands of a growing global population and to overcome the sudden and variable stresses, made worse, by climate change. This project brings together researchers from the University of Hawai’i at Manoa and Iowa State University to develop an efficient, robust genome engineering toolkit that can be used to speed the generation of resilient crops adapted to a changing environment. Reproductive barriers are a major bottleneck that limits the genetic diversity available for crop improvement.

AMES, Iowa – The immense number of possible hybrids that can be created from inbred corn plants can leave plant breeders wondering where to start when attempting to produce new crop varieties with desirable traits. But new research from an Iowa State University agronomist shows how advanced data mining techniques can enhance the efficiency of the process.

AMES, Iowa – New research led by an Iowa State University agronomist identifies clear patterns in how plants react to different environments that could lead to new ways of predicting crop performance.

The research focuses on flowering time in sorghum, a globally cultivated cereal plant, but the results could have implications for nearly all crops, said Jianming Yu, professor of agronomy and the Pioneer Distinguished Chair in Maize Breeding. The study, published recently in the peer-reviewed academic journal Proceedings of the National Academy of Sciences, focuses on phenotypic plasticity, or the way plant traits respond to environmental factors.
