Identification and Analysis of Genes Involved in Lipopolysaccharide Production and Symbiotic Efficiency in RhizobiumLeguminosarum Biovar Viciae VF39
Bacterial cell surface carbohydrates undoubtedly play an important role in signal exchange between Rhizobium and its host plant during the process of symbiotic nitrogen fixation. As a component of the outer membrane, the rhizobial lipopolysaccharide (LPS) has been hypothesized to be involved in host- specific recognition by interacting with the lectins of legumes (Wolpert and Albersheim 1976). Recent reports suggest that the function of LPS is, at least in Rhizobium leguminosarum, not restricted to the early events of attachment and recognition (Noel et al 1 986; Cava et al 1 989; DeMaagd et al 1989).
