| Outline of Final Research Achievements |
Various mutants and marker lines of Arabidopsis thaliana involved in the CLE signaling pathway, dedifferentiation, cell division, immune response, strigolactone synthesis, glucosinolate metabolism, lateral root formation and phytohormone signaling pathway were infected with a root-knot nematode, Meloidogyne incognita to elucidated molecular mechanisms of host plant responses during infection of plant-parasitic nematodes and induction of giant cells, where the site of nematode feeding and maturation. The root-knot nematode infection was suppressed in mutants involved in the CLE signaling pathway and lateral root formation. In addition, expressions of genes involved in dedifferentiation and cell division were enhanced in nematode-induced galls. These results suggested that factors implicated in the pathway or events play roles in the process of nematode infection and gall formation.
