Effectors in plant pathology

Effectors are proteins expressed by plant pathogens to aid infection of specific plant species. These molecules can alter plant processes and are central to understanding the complicated interplay between plants and their pathogens.

    Plants can experience a range of challenges, from osmotic stress to pathogen attack, requiring different types of responses. Despite this variety, two recent studies of plant transcriptomes reveal a surprising commonality in the genes induced by stress.

    Plant defence is based on a two-tiered immune system comprising pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). Effective defence against host-adapted microbial pathogens relies on mutual potentiation of immunity by both PTI and ETI components.

    Heat-shock protein 90 (HSP90) chaperones play an essential role in plant defence by assisting the folding of client proteins needed for immunity. A newly identified bacterial effector promotes disease by mimicking a HSP90 client, functioning as a minimal kinase that phosphorylates and inactivates the chaperone.

    Bacterial pathogens have a multitude of effectors that target plant host cells and promote disease. A case is made for a new suspect, phytate, as a target of a novel phytase activity for a type III effector of Xanthomonas.
