title: The nodPQ genes in Azospirillum brasilense Sp7 are involved in sulfation of lipopolysaccharides.
abstract: Here we report on the presence of sulfated lipopolysaccharide molecules in Azospirillum brasilense, a plant growth-promoting rhizosphere bacterium. Chemical analysis provided structural data on the O-antigen composition and demonstrated the possible involvement of the nodPQ genes in O-antigen sulfation.
