NAC — Cucumis sativus

Summary

CsNAC (CSA_4G361820) on cucumber chromosome 4 encodes a NAC-domain transcription factor with DNA-binding and transcription activator activity. It is associated with the regulation of root hair elongation, leaf senescence, photosynthesis, sex determination, organogenesis, meristem development, and photomorphogenesis. The gene has been linked to traits including fruit length and shape, lignin and chlorophyll content, nitrogen and sugar content, photosynthetic rate, ethylene sensitivity, root length and thickness, seedling growth, and disease tolerance. It is also associated with responses to salinity, oxidative stress, cadmium, and abiotic stresses, as well as hormone anabolism, the MAPK cascade, glucosinolate and secondary metabolism, and the TCA cycle. The protein localises to the nucleus and cytoplasm. Studies of related genes in other species link the family to drought tolerance, thermomemory, and pathogen resistance.
