TSF — Cucumis melo

Summary

MELO3C031994.2 (TSF, also known as CmMYB73, CmMYB44, and CmMYB70) on melon chromosome 7 encodes a MYB transcription factor with DNA-binding and RNA polymerase II-specific transcription factor activity, as well as abscisic acid binding, MAPKK activity, and protein phosphatase inhibitor activity. In melon, it is associated with sucrose accumulation. The gene is linked to numerous traits including phenolic compound content, adventitious root number, UV light sensitivity, submergence tolerance, shoot growth angle, phyllotaxy, anther morphology, phototropism, phosphorus uptake, photoperiod-sensitive flowering time, aphid response, stem senescence, leaf curling, seed yield, and osmotic response sensitivity. It is also associated with auxin signaling, salicylic acid signaling, phenylpropanoid and lignin metabolism, stomatal patterning, floral organ abscission, and the MAPK cascade. Studies of related genes in other species link the family to salt tolerance, aphid resistance, and defense against necrotrophic and biotrophic pathogens.
