Susceptibility Genes in Bacterial Diseases of Plants
Year: 2025
Type: review
Abstract: Plant susceptibility (S) genes exploited by pathogenic bacteria play critical roles in disease development, collectively contributing to symptoms, pathogen proliferation, and spread. S genes may support pathogen establishment within the host, suppress host immunity, regulate host physiology or development, or function in other ways. S genes can be passive, e.g., involved in pathogen attraction or required for pathogen effector localization or activity, or active, contributing directly to symptoms or pathogen proliferation. Knowledge of S genes is important for understanding disease and other aspects of plant biology. It is also useful for disease management, as nonfunctional alleles can slow or prevent disease and, because they are often quantitative, can exert less selection on pathogens than dominant resistance genes, allowing greater durability. In this review, we discuss bacterial exploitation of S genes, S-gene functional diversity, approaches for identifying S genes, translation of S-gene knowledge for disease control, and future perspectives on this exciting area of plant pathology.
