Light-Signalling Regulators GmSTF3/4 Enhance Soybean Susceptibility to Cyst Nematodes via Activation of Sugar Transporters.

ABSTRACT: Soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is a plant-parasitic nematode that causes substantial yield losses in soybean production. Light signalling is a critical environmental factor that influences photomorphogenesis and carbohydrate metabolism. However, its transcriptional regulation under pathogen-induced stress remains unclear. In this study, the biological function and regulatory mechanism of TGACG-motif binding factor 3/4 (GmSTF3/4), a shoot-to-root mobile protein in soybean (Glycine max), were investigated during H. glycines infection. Evidence was provided that light signalling modulated soybean susceptibility to cyst nematode, marked by light-enhanced nematode infection and upregulation of photoreceptor gene expression post-infection. GmSTF3/4 interacted with CONS
