Analysis of the PRA1 Genes in Cotton Identifies the Role of GhPRA1.B1-1A in Verticillium dahliae Resistance.

ABSTRACT: Verticillium wilt in cotton (Gossypium hirsutum) is primarily caused by Verticillium dahliae. Previous data suggest that prenylated RAB acceptors (PRAs) play essential roles in environmental plant adaptation, although the potential roles of PRA1 in cotton are unclear. Therefore, in this study, PRA1 family members were identified in G. hirsutum, and their roles in biotic and abiotic stresses were analyzed. Thirty-seven GhPRA1 family members were identified in upland cotton, which were divided into eight groups. Gene structure and domain analyses revealed that the sequences of GhPRA1 members in each group were highly conserved. Many environmental stress-related and hormone-response cis-acting elements were identified in the GhPRA1 promoter regions, indicati
