NSL2 and the interacting-Proteins involved in Plant immunity

Abstract

To clarify cell death processes involved in plant immunity response, we have isolated and characterized Arabidopsis mutant nsl2( necrotic spotted lesion 2; also reported as the cad1) showed hypersensitive response seen in the lesion mimic mutants. In addition, the nsl2 mutant activated PR gene (pathogen related gene) and SA and JA pathway. Inoculation of nsl2 with virulence pathogen showed restriction of bacterial growth (Plant Cell Physiol. 2005, 46: 902-912). To understand NSL2 functions, we carried out yeast two-hybrid screening. We succeeded in isolation of NSL2 interacting-proteins which may relate to plant immunity. Further characterization will be reported.
