Exogenous melatonin enhances cell wall response to salt stress in common bean () and the development of the associated predictive molecular markers.

Common bean () is an important food crop; however, its production is affected by salt stress. Salt stress can inhibit seed germination, promote senescence, and modify cell wall biosynthesis, assembly, and architecture. Melatonin, an indole heterocycle, has been demonstrated to greatly impact cell wall structure, composition, and regulation in plants under stress.
