<i>GmPLC8</i> enhances drought resistance in soybean by regulating stomatal closure.

ABSTRACT: Soybean (Glycine max (L.) Merr.) is an economically important crop. Drought adversely affects nutrient acquisition and early vegetative development, thereby constraining the growth potential of soybean seedlings. Phospholipase C (PLC) participates in diverse biological processes, yet its function in soybeans has not been fully explored. In this study, we generated GmPLC8-overexpressing (OE) and GmPLC8-silenced soybean seedlings to investigate the function of GmPLC8. The results showed that GmPLC8-OE lines exhibited higher tolerance than wild-type seedlings, whereas GmPLC8-silenced seedlings were more sensitive. This was associated with reduced malondialdehyde (MDA) and hydrogen peroxide (H₂O₂) levels in GmPLC8-OE lines,
