The early events in legume nodulation by Rhizobium spp. involve a conserved gene cluster known as the common nod region. A broad-host-range plasmid (pEA2-21) containing a Bradyrhizobium japonicum nodDABC-lacZ translational fusion was constructed and used to monitor nod gene expression in response to
Random transcription fusions with Mu d1(Kan lac) generated three mutants in Rhizobium fredii (strain USDA 201) which showed induction of beta-galactosidase when grown in root exudate of the host plants Glycine max, Phaseolus vulgaris, and Vigna ungliculata. Two genes were isolated from a library of
The first specific reaction in the biosynthesis of isoflavonoid compounds in plants is the 2-hydroxylation, coupled to aryl migration, of a flavanone. Using a functional genomics approach, we have characterized a cDNA encoding a 2-hydroxyisoflavanone synthase from soybean (Glycine max). Microsomes
