A time-resolved metabolomics study of potato cultivar responses to <i>Pseudomonas syringae</i>.

ABSTRACT:

Introduction

The bacterial plant pathogen Pseudomonas syringae poses a threat to various crops, including potato (Solanum tuberosum). Its pathogenicity and virulence are enabled by, among other factors, its type III secretion system, which delivers effectors into the host plant. While differences in cultivar responses offer a sustainable control strategy, the underlying temporal metabolic mechanisms in potatoes remain poorly characterised.

Methods

This study employed an untargeted LC-MS metabolomics to investigate dynamic metabolic reprogramming in contrasting potato cultivars, Sifra and Valor, following inoculation with P. syringae. The metabolomic analysis was conducted at three intervals: 24 hours, 48 hours, and 72 hours post-inoculation.
