Lecture Overview
Legume plants form specialized root nodules to host "rhizobia", nitrogen-fixing bacterial symbionts. Rhizobia hosting legumes are able to grow without exogenous nitrogen fertilizer allowing them to be high in protein and to provide nutrition to surrounding plants. In part 1 of her talk, Long gives an overview rhizobium-legume symbiosis including infection and nodule formation and the chemical signals exchanged between the plant and the bacteria.  More >>
