NTT — Cucumis melo

Summary

MELO3C009030.2 (CmNTT) on melon chromosome 9 encodes a zinc-finger C2H2 transcription factor of the WIP family with sequence-specific DNA binding and DNA binding transcription factor activity. The gene is associated with sex determination, carpel development, fruit replum development, transmitting tissue development, and cell fate determination. It is linked to fruit shape, seed coat color, seed weight, anthocyanin content, lignin biosynthesis, flowering time, and responses to abiotic stresses including high and low temperature, oxidative stress, and insect damage. Associations also include proanthocyanidin and anthocyanin metabolism, sucrose-mediated signaling, and regulation of cell polarity. The encoded protein localizes to both the nucleus and cytoplasm. Studies of related genes in other species link the family to transmitting tract formation, replum development, anthocyanin and proanthocyanidin accumulation, and resistance against Pseudomonas syringae.
