A Review on Molecular and Cellular Basis of Plant-Parasitic Root Knot Nematode-Host Interactions: Host Resistance

Abstracts: Root‐knot nematodes (RKN), (Meloidogyne spp.) are obligate endoparasites of more than 3000 species of plants, which results in $70 billion worth of economic loss every year, worldwide. Controlling of obligated plant parasitic rootknot-nematode is generally difficult and also with the banning of many nematicides chemicals that control nematode, because of adverse environmental impacts, it is recommended to develop host resistance genes. Although, many R-gene confer resistance to RKN have been identified, the majority of these gene lose durability of resistance and affected by high temperature. As the results knowledge of molecular and cellular mechanism underlying host resistance condition is essential to develop durable resistance gene that provide stable resistance under different condition as well as provide resistance to many RKN species. Considering that, we have conducted extensive literature reviews on recently discovered diverse RKN resistance genes (structural and functional characterized) with their underlying mechanism of the resistance responses induced by different types of nematode resistance genes. In this review, several independent single dominant R genes confer resistance to RKN have been reported. These Resistance genes include: Mi-gene, Ma-gene, PsoRPM2-gene, SacMi-gene and RMja genes confer resistance to RKN in Tomato (L. peruvianum), Prunus species (Myrobalan plum = Prunus cerasifera), woody fruit tree (Prunus sogdiana and transgenic tobaccos) and Eggplants (S. aculeatissimum) respectively. The structure, functions and mechanism of resistance mediated by these genes were summarized in this review. Keywords: Meloidogyne spp, Rootknot nematodes, Resistance genes, Eggplants, Dominant R gene, Mi gene.
