Gene Details:

• Gene ID: Solyc07g052620
• Gene Symbol: SlBBX17
• Gene Name: BBX transcription factor 17
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• SlMPK1- and SlMPK2-mediated SlBBX17 phosphorylation positively regulates CBF-dependent cold tolerance in tomato.
• Using approaches of reverse genetics, biochemical and molecular biology we characterized a BBX transcription factor, SlBBX17, which positively regulates cold tolerance in tomato.
• Overexpressing SlBBX17 enhanced C-repeat binding factor (CBF)-dependent cold tolerance in tomato plants, whereas silencing SlBBX17 increased plant susceptibility to cold stress.
• SlBBX17 physically interacted with SlHY5 to directly promote the protein stability of SlHY5 and subsequently increased the transcriptional activity of SlHY5 on SlCBF genes under cold stress.
• A mechanistic framework by which SlMPK1/2-SlBBX17-SlHY5 regulated transcription of SlCBFs to enhance cold tolerance, thereby shedding light on the molecular mechanisms of how plants respond to cold stress via multiple transcription factors.
