A number of transcription factors (TFs) modulate SAG expression to promote or delay senescence. Here we show that NAC016, the previously uncharacterized senescence-associated NAM/ATAF1/2/CUC2 (senNAC) TF in Arabidopsis thaliana, promotes senescence. Leaves of nac016 mutants remained green under senescence-inducing conditions, and leaves of NAC016-overexpressing (NAC016-OX) plants senesced early. Under dark-induced senescence (DIS) conditions, nac016 mutants had low ion leakage, and retained the proper balance of photosystem proteins and normal grana thylakoid shape much longer than wild-type plants, suggesting that nac016 acts as a functional stay-green type senescence mutant. Under DIS conditions, SAGs (NYC1, PPH, SGR1/NYE1 and WRKY22), including senNACs (JUB1, NAP, ORE1, ORS1 and VNI2), were down-regulated in nac016 mutants and up-regulated in NAC016-OX plants. In addition to its role in senescence, NAC016 also affects abiotic stress. Under salt and oxidative stress conditions, NAC016 expression rapidly increased in developing leaves, possibly to promote senescence. Indeed, under the stress conditions, nac016 mutants stayed green and NAC016-OX plants senesced rapidly. To identify direct targets of the NAC016 TF in the regulation of leaf senescence, we conducted yeast one-hybrid assays, which strongly suggested that NAC016 binds to the promoters of NAP and ORS1. Based on these results, we propose that NAC016 regulatory mechanisms promoting leaf senescence exhibit cross-talk with the salt and oxidative stress-responsive signaling pathways."xsd:string |
