Shaping the biology of citrus: I. Genomic determinants of evolution

Abstract We performed genomic analyses on wild species of the genus Citrus to identify major determinants of evolution. The most notable effect occurred on the pathogen‐defense genes, as observed in many other plant genera. The gene space was also characterized by changes in gene families intimately...
