The side‐chains of lipopolysaccharides from Pseudomonas syringae pvs. aptata, pisi and phaseolicola contain D‐rhamnose. Using 1 H‐and 13 C‐nuclear magnetic resonance spectroscopy and methylation analysis, the side‐chains of NCPPB 871, the neopathotype strain of pv. aptata , and strain 299A of pv. pisi race 1 were found to be of identical structure:Side‐chains from NCPPB 52, the neopathotype strain of pv. phaseolicola , were based on the same backbone structure, but were substituted to the extent of approximately 67% with branch D‐fucose residues:Side‐chain structures are correlated with a previously proposed serouping system.
