Structural characterization of extracellular polysaccharides of Azorhizobium caulinodans and importance for nodule initiation on Sesbania rostrata.

Molecular microbiology - 1 Apr 2004

D'Haeze Wim, Glushka John, De Rycke Riet, Holsters Marcelle, Carlson Russell W

Abstract excerpt

During lateral root base nodulation, the microsymbiont Azorhizobium caulinodans enters its host plant, Sesbania rostrata, via the formation of outer cortical infection pockets, a process that is characterized by a massive production of H(2)O(2). Infection threads guide bacteria from infection pockets towards nodule primordia. Previously, two mutants were constructed that produce lipopolysaccharides (LPSs) similar...
