Gene Details:

• Gene ID: Solyc03g005570
• Gene Symbol: SlMYB15
• Gene Name: SlMYB15 transcription factor
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• Tomato SlMYB15 transcription factor targeted by sly-miR156e-3p positively regulates ABA-mediated cold tolerance.
• We have previously demonstrated that SlMYB15 positively regulates cold tolerance in tomato. However, the underlying mechanism of SlMYB15-induced cold tolerance remains largely unexplored.
• Here, cold-induced SlMYB15 was found to be targeted by Solanum lycopersicum (sly)-miR156e-3p, which was decreased by cold stimulus in tomato. Tomato plants overexpressing sly-MIR156e-3p displayed significant enhancement in susceptibility to cold stress, while silencing of sly-miR156e-3p by an artificial microRNA interference strategy caused tomato plants to be more tolerant to cold.
• Moreover, both overexpression of SlMYB15 and silencing of sly-miR156e-3p increased the accumulation of ABA. SlMYB15 directly binds to the promoter regions of ABA biosynthesis and signalling genes, SlNCED1 and SlABF4, resulting in enhanced cold tolerance.
• Taken together, our results demonstrate that SlMYB15 targeted by sly-miR156e-3p confers higher survivability to cold stress via ABA and ROS signals. This study provides valuable information for breeding improved crop cultivars better equipped with cold tolerance.
