Gene Details:

• Gene ID: Cs3_sc004370.1_g0600.1
• Gene Symbol: CmBBX22
• Gene Name: BBX transcription factor 22
• Genome: Chrysanthemum morifolium genome
• Species: Chrysanthemum morifolium

Functional Descriptions:

• CmBBX22, a transcription factor of chrysanthemum, was verified to confer drought tolerance in Arabidopsis thaliana.
• The heterologous expression of CmBBX22 delays leaf senescence and improves drought tolerance in Arabidopsis.
• Overexpression of CmBBX22 in chrysanthemum was found to reduce plant drought tolerance, whereas expression of the chimeric repressor CmBBX22-SRDX was found to promote a higher drought tolerance than that shown by wild-type plants, indicating that CmBBX22 negatively regulates drought tolerance in chrysanthemum.
• We were thus able to establish the mechanisms whereby the transcriptional activator CmBBX22 negatively regulates drought tolerance in chrysanthemum via the regulation of the abscisic acid response, stomatal conductance, and antioxidant responses.
