| Research Abstract |
Various defense reactions such as hypersensitive cell death are induced in plants on recognition of microbe-associated molecular patterns (MAMPs). In this study, we showed that chitin oligosaccharides, which are representative fungal MAMPs, elicit the production of both reactive oxygen and nitrogen species, and the production of these radicals is required for the induction of hypersensitive cell death in rice cultured cells. In addition, we performed functional analysis of rice EL5 gene, whose expression is induced by chitin, confirmation of interaction between EL5 and GAPDH in rice cells, and characterization of GAPDH during cell death. Our data indicate that GAPDH, a glycolysis enzyme, is also involved in the induction of cell death in plants.
