Plant breeders are challenged with sustaining global crop improvements. Is there a limit to crop yield?
Our lab is addressing this question using three favorite plants: tomatoes, Lisianthus and autotetraploid roses. By integrating in a single web-based platform a broad germplasm base, deep ontology defined phenotypes, and multiple genome sequences we identify genes and mechanisms that dictate crop productivity.
Our integrated breeding efforts unite classical and genomics assisted methods to demonstrate that yield barriers are only there to be broken.
The tomato genome was published in Nature on May 31, 2012, culminating years of work by the Tomato Genome Consortium, a multi-national team of scientists from 14 countries.
