Host Response to Nematode Infection

Ralstonia solanacearum colonization of tomato roots infected by Meloidogyne incognita

“…Root‐knot nematode infections modify host tissues enriching their nutritional value. Root galls have been found to contain more amino acids, auxins, RNA, DNA and phosphorous than healthy tissues (Bird, ; Krusberg, ), and these substances might promote the growth and establishment of bacterial pathogens (Sitaramaiah & Pathak, ). Our results evidenced that R. solanacearum mainly colonized root‐nematode galls, suggesting that root‐knot nematode infection increases disease susceptibility by modifying host tissues, consistent with the results of previous studies (Deberdt et al, ; Fukudome & Sakasegawa, ; Johnson & Powell, ; Sitaramaiah & Pathak, ).…”

Pathogenesis of Nematode-Infected Plants

“…Similarly, altered cells induced by Rotylenchulus can be similar to ini tially stimulated cells induced by root-knot nematode (13,29) and the cells next to developing syncytia of Heterodera (25). reviewed and discussed by several workers (21, 26, 46,59,81,97). The mechanism of penetration and establishment of various Heterodera spp.…”

Plant Response to Root-Knot Nematode

“…This review considers only very briefly the responses of the nematode to the plant and does not cover plant resistance to nematodes because these topics have been dealt with in recent reviews (12,71). Also, the early literature on the responses of plants to nematode infections is not discussed, as it has been well documented in a series of reviews in the ten year period from 1961 (27, 33,50,55,75,89). Some of the statements made in this review are speculative and in time will probably be shown to be incorrect.…”
