Colonization of Serendipita indica promotes resistance against Spodoptera exigua in onion (Allium cepa L.).

ABSTRACT: Plant-endophyte symbiosis influences plant defense and growth. Serendipita indica is a root endophyte that promotes growth and induces tolerance against biotic and abiotic stress in plants. In this study, we examined the effect of S. indica colonization on herbivore (Spodoptera exigua) resistance of onion (Allium cepa L.). We found that colonization of S. indica in the roots of onion significantly reduced the feeding damage of leaves by S. exigua larvae, and also resulted in a reduction in weight gain of the larvae when fed on S. indica plants. This enhanced resistance is a result of modulation of antioxidant and defense enzymes/genes in the host by S. indica mutualism. Specifically, the activities of enzymes such as Superoxide dismut
