Gene Details:
- Gene ID: CsaV3_3G036040
- Gene Symbol: CsRAX2
- Gene Name: R2R3-MYB transcription factor 2
- Genome:
- Species: Cucumis sativus
Functional Descriptions:
- CsRAXs negatively regulate leaf size and fruiting ability through auxin glycosylation in cucumber.
- Csrax5 single mutant exhibited enlarged leaf size and stem diameter, and Csrax1/2/5 triple mutant displayed further enlargement phenotype.
- Overexpression of CsRAX1 or CsRAX5 gave rise to smaller leaf and thinner stem. The fruiting ability of Csrax1/CsRAX2/CsRAX5 plants was significantly enhanced, while that of CsRAX5 overexpression lines was greatly weakened.
- Biochemical data indicated that CsRAX1/CsRAX5 directly promoted the expression of auxin glucosyltransferase gene CsUGT74E2.
- CsRAXs function as repressors for leaf size development by promoting auxin glycosylation to decrease free auxin level and cell division in cucumber.
