Abstract:

Recent researches on the structure and function of NAC transcription factors(TFs)and their regulating mechanisms during the process of fruit development and ripening are reviewed in this paper. It is suggested that NAC TFs affect fruit ripening through ethylene and multiple hormone pathways. Ethylene pathway includes ethylene induced NAC TFs regulating fruit ripening,NAC TFs regulating the upstream TFs of ethylene signal systems and TFs directly regulating the main ethylene synthesis genes to control fruit maturity. Multiple hormone pathways include TFs affecting fruit maturity via auxin,abscisic acid and gibberellin/brassinolide pathways.

Key words: NAC, transcription factor, fruit, development, ripening
