摘要: Lipopolysaccharides (LPS) are among the known pathogen-associated molecular patterns (PAMPs). LPSs potent elicitors of PAMP-triggered immunity (PTI), and bacteria have evolved intricate mechanisms to dampen PTI. Here we demonstrate that Xylella fastidiosa (Xf), a hemibiotrophic plant pathogenic bacterium, possesses long chain O-antigen enables it delay initial recognition, thereby allowing effectively skirt elicitation innate establish itself in host. Lack modifies perception Xf hallmarks PTI, such as ROS production specifically xylem tissue compartment, not traditionally considered spatial location To explore translational applications our findings, pre-treatment plants with LPS primes grapevine defenses confer tolerance challenge.
