“…The O-methylation of LOS O-antigen residues, Rhamnose included, is instead more frequently found in plant-associated bacteria, either Exopolysaccharides or Lipopolysaccahrides. 14,38,39 As for the core OS, this was characterized by an extensive, multiple non-stochiometric O-methylation of the sugar residues, distributed along the whole saccharide chain. This included the novel and unprecedented O-methylation at position O5 on the alternative terminal Kdo/Ko units and the extreme non-reducing core region that was capped by a rhamno-trisaccharide chain extensively O-methylated, which further decreases the hydrophilicity of the outermost portion of the LOS (Figure 4).…”

“…LPS possess long O-antigen that restrict the initial plant recognition, thereby enabling elicitation of innate immunity and helping to evade successfully into the host (Ranf et al, 2015; Rapicavoli et al, 2018). Whereas the recent plant immunology study also demonstrated that acetylated LPS in Arabidopsis thaliana protects the LPS from immune recognition (Vanacore et al, 2022), and it is found to activate biphasic production of reactive oxygen species (ROS) (Shang-Guan et al, 2018). In addition, LPS has been discovered to be a fundamental factor that increases bacterial viability and aids in inter-organismic interaction as well.…”
