| Abstract: | The lipopolysaccharide (LPS) side chain from Pseudomonas syringae pv. tabaci strain NCPPB 79 (=CFBP 1615) contained l ‐ and d ‐rhamnose, and GlcNAc. Using methylation analysis, periodate oxidation, Smith degradation and 1H‐ and 13C‐nuclear magnetic resonance spectroscopy, the repeat unit was found to have the structure:  This structure is correlated with a previously proposed serogrouping system. The involvement of LPS generally in plant disease is briefly discussed. |
