Silencing of GhORP_A02 enhances drought tolerance in Gossypium hirsutum.

Background: ORP (Oxysterol-binding protein-related proteins) genes play a role in lipid metabolism, vesicular transferring and signaling, and non-vesicular sterol transport. However, no systematic identification and analysis of ORP genes have been reported in cotton.

Result: In this study, we identified 14, 14, 7, and 7 ORP genes in G.
