Gene Details:

• Gene ID: GH_D11G2038
• Gene Symbol: GhKRP6
• Gene Name:
• Genome: TM1_NBI
• Species: Gossypium hirsutum

Functional Descriptions:

• Cell cycle-dependent kinase inhibitor GhKRP6, a direct target of GhBES1.4, participates in BR regulation of cell expansion in cotton.
• The study found that GhKRP6 was significantly induced by the BR hormone and that GhBES1.4 directly promoted the expression of GhKRP6 by binding to the CACGTG motif in its promoter region.
• GhKRP6-silenced cotton plants had smaller leaves with more cells and reduced cell size.
• Furthermore, endoreduplication was inhibited, which affected cell expansion and ultimately decreased fiber length and seed size in GhKRP6-silenced plants compared with the control.
• Our study also found that GhKRP6 could interact directly with a cell cycle-dependent kinase called GhCDKG. Taken together, these results suggest that BR signaling influences cell expansion by directly modulating the expression of cell cycle-dependent kinase inhibitor GhKRP6 via GhBES1.4.
