Loss of PR1 function enhances Arabidopsis resistance to <i>Botrytis cinerea</i>

2026-06-11

Abstract excerpt

PATHOGENESIS-RELATED 1 (PR1) is one of the most widely used markers of salicylic acid (SA)-dependent plant immunity, yet its direct functional contribution to pathogen defence remains poorly understood. Here, we investigated the role of PR1 in Arabidopsis thaliana by analyzing a pr1 loss-of-function mutant challenged with bacterial and fungal pathogens and fumonisin B1 (FB1)-induced cell death. Notably, loss of...
