Proposed working model of VNI2 in the regulation of leaf senescence under high salinity. The VNI2 gene is transcriptionally induced during leaf senescing process. The VNI2 transcription factor regulates the COR/RD genes by binding to their gene promoters. The COR/RD proteins play a role in the protection of leaf cells from diverse cellular damages, establishing age-dependent stress resistance. The transcriptional activation activity of VNI2 is also modulated by salt stress, linking plant salt stress resistance to leaf senescence.
