NAC — Cucumis sativus

Summary

CsNAC (CSA_2G338830) on cucumber chromosome 2 encodes a NAC-domain transcription factor with DNA-binding transcription activator activity, sequence-specific DNA binding, and protein homodimerization activity. It localises to the nucleus and cytoplasm. The gene is associated with regulation of root hair elongation, leaf senescence, photosynthesis, sex determination, meristem development, organogenesis, and the MAPK cascade. It has been linked to traits including fruit length and shape, chlorophyll content, photosynthetic rate, nitrogen and sugar content, lignin content, ethylene sensitivity, root length and thickness, seedling growth, and disease tolerance. Associations also include responses to oxidative stress, cadmium, drought, and pathogens, as well as brassinosteroid catabolism, anthocyanin biosynthesis, and abscisic acid and jasmonic acid signalling. Studies of related genes in other species link the family to drought tolerance, thermomemory, and pathogen resistance.
