Genetic Analysis of ,-Plant Interactionsages at which bacteria and plants interact. This is particularly relevant to the legume-. symbiosis, which proceeds by a series of steps involving both the host plant and the bacterial symbiont. These steps, originally outlined by Vincent (1980), include attachment, root hair curling, meristem initi

Some tropical strains can nodulate and fix nitrogen on a large number of genera belonging to various tribes of Leguminosae and even on the non-legume genus ..

Genetic analysis of the microsymbiont has revealed interesting details about this symbiotic association.

Intercellular Communication and Recognition in the Rhizobium-Legume Symbiosis (Rolfe et al 1981). The bacteria respond to plant-secreted compounds which stimulate the expression of the nodulation genes (Innes et al 1985; Mulligan and Long 1985; Rossen et al 1985). The bacteria are thought to respond by releasing compounds which induce marked root hair distortion and by elabo
