Divergent evolution of genes in the genus : impacts of annuals and perennials' life history strategies.

Within the family , the genus is composed of two subgenera annuals (2n=40) and perennials. This life strategy transition may have differentially affected the evolution of various gene families. Its cultivated species has high level of susceptibility to major pathogens including viruses, bacteria and fungi.

Dynamic Evolution of Genes in Dalbergioids.

is a large group within the family that consists of diverse plant species distributed in distinct biogeographic realms. Here, we have performed a comprehensive study to understand the evolution of the nucleotide-binding leucine-rich repeats (NLRs) gene family in . The evolution of gene families in this group is affected by a common whole genome duplication that occurred approximately 58 million years ago, followed by diploidization that often leads to contraction.
