Genetic regulation of nodule infection and development
Nodule formation is a multistep process requiring coordinated gene expression of the host-plant and Rhizobium. Tsyganov et al. (pp. 357-366) undertake a genetic dissection of the initiation of nodule formation. They propose the existence of two groups of plant genes controlling the infection process and nodule tissue development, and of possible cross-talk between them.
