Dose-dependent transcriptional reprogramming and lipid-associated defense under salt stress in mung bean (Vigna radiata).

ABSTRACT:

Background

Salt stress severely limits crop productivity worldwide. However, in mung bean (Vigna radiata), an important legume for agriculture and nutrition, the transcriptional mechanisms underlying dose-dependent salt adaptation remain largely unexplored.

Results

We combined physiological assays, transcriptomic profiling, and a dose-adapted time-ordered gene co-expression network (TO-GCN) analysis to dissect the regulatory responses of mung bean under a gradient of salt stress concentrations. Salt exposure increased reactive oxygen species and osmolyte accumulation, accompanied by transcriptional reprogramming that intensified with higher salinity. Network analysis identified eight hierarchically organized regulatory layers corresponding to distinct salt stress stages, rev
