As genomic sequencing tools become faster and less expensive, the amount of data available to plant researchers has exploded. The Fei lab develops new tools and resources to analyze and integrate these datasets, thereby helping researchers understand how genes work together. One example is the creation of the tomato pan-genome, which he and Dr. Giovannoni analyzed to discover a new version of a gene, called TomLoxC, which contributes to a desirable flavor. The rare version was present in many wild tomatoes but is largely absent in most commercial tomatoes today. Thanks to the pan-genome, “lost” genes encoding traits like flavor, disease resistance and stress tolerance can be discovered and reintroduced into tomatoes.
