A PLANT-PATHOGEN INTERACTIONS: A BRIEF INSIGHT INTO A COMPLICATED STORY

Le résumé fourni par la source

Pseudomonas syringae pv.tomato, a bacterial plant pathogen, poses a significant threat to crop production and often leads to considerable yield losses.Due to its infectivity in Arabidopsis thaliana, a widely studied plant model, P. syringae serves as an exemplary model organism for studying the intricacies of infection processes.This short communication offers a molecular biology-based overview of bacterial pathogenesis and highlights the interplay between the virulence factors of the pathogen and the defence mechanisms of the host.Phytohormones, central regulators of the immune response, and the methylation status of the host are of central importance for plant defence.Wide genome methylation changes are dynamic under the influence of pathogens, and it is hypothesised that loss of DNA methylation in the host plant (Arabidopsis thaliana Col-0) plays a role in resistance to bacteria.This overview tackles the multiple functions of these important defence mechanisms and examines how the pathogen subverts their functions to facilitate the progression of infection.
