These characteristics suggest that this gene family may be an important link between the response to pathogens and plant growth and development. In this investigation, the DRM1/ARP genes were identified in the genome of four legume species. The deduced proteins were separated into three distinct groups, according to their sequence conservation. The expression profile of soybean genes from each group was measured in different organs, after treatment with auxin and MeJA and in response to the nematode Meloidogyne javanica. The results demonstrated that this soybean gene family is predominantly expressed in root. The time auxin takes to alter DRM1/ARP expression suggests that these genes can be classified as a late response to auxin. Nevertheless, only the groups 1 and 3 are induced in roots infected by M. javanica and only group 3 is induced ...
