The pleiotropic phenotype of an auxotrophic purL mutant (SVQ295) of Sinorhizobium fredii HH103 has been investigated and SVQ295 showed auto-agglutination when grown in liquid TY medium and its lipopolysaccharide (LPS) electrophoretic profile differed from that of its parental strain HH103-1.

The K-antigen polysacharide of S. fredii HH103 is a homopolysaccharide, which is composed of a disaccharide repeating unit and the sugar residues are attached via a glycosidic linkage to the OH group of the 3-hydroxybutyramido substituent.

Transposon insertion into neoL has two impacts on symbiosis with Williams soybean: nodulation rate is reduced slightly and competitiveness for nodulation is decreased significantly, and Mutant SVQ287 retains its ability to form nitrogen-fixing nodules on other legumes, but final nodule number is attenuated on Cajanus cajan.
Structural determination of a 5-O-methyl-deaminated neuraminic acid (Kdn)-containing polysaccharide isolated from Sinorhizobium fredii.

It is likely that the appearance of this new Kdn-containing polysaccharide is a consequence of the mutation, and this is the first report of the presence of Kdn in a rhizobial poly Saccharide, as well as being the first structure described containing 5-O-Me-Kdn.
