Gene Details:

• Gene ID: GH_A12G0368
• Gene Symbol: GhMYB4
• Gene Name:
• Genome: TM1_NBI
• Species: Gossypium hirsutum

Functional Descriptions:

• In the tapetum of early-stage cotton anthers, upregulated expression of GhMYB4 under HT and overexpressed GhMYB4 under normal temperature both led to severe male sterility phenotypes, coupled with enhanced expression of GhCKI.
• The expression of GhMYB4 in tetrad stage anthers and promoted the formation of the GhMYB4/GhMYB66 heterodimer, which in turn elevated the transcription of GhCKI in the tapetum, leading to male sterility.
• We shed light on the GhMYB66–GhMYB4–GhCKI regulatory pathway in response to HT in cotton anthers.
