NST1 — Glycine max

Summary

GmNST1 (GLYMA_16G019400V4) encodes a NAC-domain transcription factor with sequence-specific DNA binding and protein homodimerization activity. It localizes to the nucleus and endoplasmic reticulum. In soybean, this gene is associated with lignin biosynthesis, secondary cell wall biogenesis, fruit and anther dehiscence, abscission, abscisic acid homeostasis, stomatal closure, leaf senescence, root cap development, and responses to salt and ethylene signaling. It has been linked to drought tolerance and salt tolerance traits, as well as phenotypes including pod dehiscence, stem stiffness, vascular bundle strength, and secondary cell wall thickening in the anther endothecium. Related genes in other species are associated with secondary wall formation and silique dehiscence, with mutants showing fragile stems and indehiscent siliques lacking secondary walls.
