| Research Abstract |
To analyze the host plant response mechanism related to the parasitic root-knot nematode infection, we performed the infection assay using ethylene-insensitive mutant lines and knockdown lines of symbiosis genes, of a dwarf model tomato cv. Micro-Tom. The result indicated that the egg mass formation was suppressed in the ethylene-insensitive lines with the suppression level positively linked to the degree of insensitivity. It was also shown that the root-knot nematode infection was suppressed in the knockdown lines of symbiosis genes.
