Transgenic soybean overexpressing GmNAC085 enhanced expression of important genes under salinity stress condition

Abstract

Climate change has made abiotic stresses such as drought and salinity biggcr threats to ecosystem and global food security. In response to unfavorable conditions, physiological, biochemical and molecular activities in plants are altered. Particularly, various members of NAC (NAM, ATAF1/2, CUC2) transcriptional factor family have been reported to be the key regulators in modulating multiple biological processes of plant responses to osmotic stress conditions caused by drought and salinity. Previously, transgenic studies have shown the positive regulatory role of GmNAC085, a NAC transcription factor from soybean (Glycine max), in plant resistance against drought stress. Therefore. in this study, we extended the investigation on its contribution to salinity stress.
