Tomato Phylogenomics Study

Geogenomics post-doc James Pease (working jointly between the Dick and Smith labs) and colleagues have just published a major paper on the phylogenomics of the tomato lineage, which has its origin in the Andean uplands. Here is the U-M press release, and here is a link to the Plos Biology paper. Using transcriptome data, this paper examines the major sources of adaptive variation in tomatoes, including adaptations associated with climatic and edaphic environments (e.g. heavy metal tolerance). Interestingly, much of the adaptive variation was obtained through introgressive hybridization. This paper is full of data, insights, and is at the leading edge of the integration of transcriptomics, phylogeny and biogeography. Congrats James!
