Genome-wide Analysis and Expression Divergence of the Trihelix family in Brassica Rapa: Insight into the Evolutionary Patterns in Plants

Abstract Trihelix gene family is an important transcription factor (TF) family involved in plants’ growth and development. This extensive study of trihelix genes from Arabidopsis thaliana to Brassica rapa could shed light on the evolution in plants and support crop breeding. In this study, a total o...
