GmNAC81 Inversely Modulates Leaf Senescence and Drought Tolerance

Abstract: Glycine max NAC81 (GmNAC81) is a downstream effector of the DCD/NRP-mediated cell death signaling, which interacts with GmNAC30 to fully induce the caspase 1-like vacuolar processing enzyme (VPE) expression, the executioner of the cell death program. GmNAC81 has been previously shown to positively modulate leaf senescence via the NRP/GmNAC81/VPE signaling module. Here, we examined the transcriptome induced by GmNAC81 overexpression and leaf senescence and showed that GmNAC81 further modulates leaf senescence b… Show more

“…Different TF families participate in the ongoing senescence, mainly the NAC [ 5 , 25 , 28 , 38 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ], MYB [ 13 , 16 ], AP2/ERF [ 49 , 50 ], and WRKY [ 17 , 51 , 52 , 53 ] families. In Arabidopsis, several regulatory gene networks have already been characterized and the crosstalk regulation between phytohormones and TFs is extensively understood [ 54 ].…”

“…SNAC-A (ATAF) is the most represented subfamily in senescence; 90% of the genes are differentially expressed in leaf senescence (10 of 11 members). Within this family, GmNAC018 , GmNAC030 , GmNAC039, and GmNAC043 are SAGs displaying stress-responsiveness [ 5 , 41 ] ( Table 1 ). GmNAC018 and GmNAC039 are putative paralogs and display similar induction patterns, with expressive upregulation by simulated drought, ER, and biotic stresses [ 41 ].…”
