Soybean cyst nematode (SCN, Heterodera glycines) is a serious root parasite of soybean (Glycine max) that induces extensive gene expression changes associated with pleiotropic biological activities in infected cells. However, the impacts various SCN Hg Types on host transcriptome reprogramming remain largely unknown. Here, we developed and used two recombinant inbred lines (RIL-72 RIL-137) to profile infection sites during resistant susceptible interactions Type 1.2.5.7 0. bioassays indicated RIL-72 was but 0, whereas RIL-137 both types. Comparative analysis induced by revealed distinct regulation number similarly oppositely regulated genes. The levels genes line appeared be insufficient mount an effective defense against SCN. functional importance confirmed using virus silencing overexpression approaches. Further comparisons shared as well Type– genotype–specific reprogramming. Shared responses were mediated through common SCN–responsive conserved immune signaling, derived from genetic variability, metabolic hormonal differences, varied protein phosphorylation ubiquitination. mechanisms together would enable plants trigger tailored types adapt response their backgrounds.
