Plant responses to nodulation factors

Curr Opin Plant Biol. 1999 Dec;2(6):483-9. doi: 10.1016/s1369-5266(99)00018-7.


The focus of research on signalling in Rhizobium-legume interactions has moved from understanding the structure and synthesis of rhizobially made Nod factors, towards an analysis of how they function in plants. Nod-factor-induced changes in ion fluxes across membranes, followed by establishment of an oscillation of intracellular Ca(2+) concentration, point to the involvement of a receptor-mediated signal transduction pathway. Progress towards the identification of components in this pathway is being made by identifying Nod-factor binding proteins, isolating plant mutants that are defective in signalling and analysing plant responses to Nod factors.
