GmNAC81 involved in leaf senecence and drought stress

We examined the transcriptome induced by GmNAC81 overexpression and leaf senescence and showed that GmNAC81 further modulates leaf senescence by regulating an extensive repertoire of functionally characterized senescence-associated genes (SAGs). GmNAC81 overexpression also uncovered the regulation of typical drought-responsive genes. Key regulators and effectors of ABA signaling were suppressed by GmNAC81 overexpression. RNA was extracted from leaves collected in two developmental stages of the plant, vegetative stage three (V3; 20 days after germination, DAG) and reproductive stage six (R6; 80 DAG). Each developmental stage comprised a set of nine libraries.
