Research Abstract |
Nod factors secreted from rhizobia lead to the formation of novel organs, termed nodules. We focused on Lotus japonicus NSP1 and NSP2, the components of nod factor signaling pathway, and analyzed their actions in relation to HAR1-mediated systemic regulation of nodulation. Then we identified a nucleoporin Seh1 required for nodulation and arbuscular mycorrhization, and elucidated its physical interaction with NUP85.Furthermore, we identified a novel regulator TML that functions in the roots downstream of HAR1.
