Regulation of host gene expression during nodule development in soybeans
The processes leading to the development of the nitrogen fixing root nodule in legumes is highly complex and involves many discrete events. In this symbiotic association between the leguminous plant and bacteria in the genus Rhizobium/Bradyrhizobium, the symbionts are in constant communication, both emitting and responding to a variety of signals that influence the progression of this association. Root nodule development is accompanied by the expression of several host and rhizobial genes. These genes are expressed in a very regulated manner at very distinct developmental stages, suggesting involvement of multiple but distinct induction signals.
