Gene Details:

• Gene ID: Csa_3G740790
• Gene Symbol: CsRAX2
• Gene Name: R2R3-MYB transcription factor 2
• Genome: Cucumis sativus ASM407v2
• 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.
