Functional evaluation of pathogenesis-related protein-1 (PR1) genes in mung bean (Vigna radiata) response to Pythium myriotylum.

ABSTRACT:

Background

Pythium myriotylum Drechsler is considered to be one of the pathogens of mung bean (Vigna radiata (L.) R. Wilczek) root rot, which threatens the yield of V. radiata. Pathogenesis-related protein 1 (PR1) is an important plant defense protein against various stressors. However, the role of PR1 in V. radiata resistance to P. myriotylum remains largely unknown.

Results

In this study, we identified six PR1 family members containing the conserved CAPE1 (CAP-derived peptide 1) domain (PxGNxxxxxPY) through bioinformatic analysis of the V. radiata genome. VrPR1 expression was significantly induced after P. myriotylum infection in V. radiata plants, and three candidate genes (VrPR1-3, VrPR1-4, and VrPR1-6) were selected to investigate their molecular characteristics and rol
