Abstract:
... Root-knot nematodes are obligate parasites that invade the roots of agricultural plants and induce the formation of specialized feeding structures, especially races 3 and 4 of the southern root-knot nematode. However, not much is known about the defense mechanisms of plants against the invasion of M. incognita race 1. In this study, we characterized and performed functional analysis of the CC-NBS- ...
