Plant Signals Anticipate the Induction of the Type III Secretion System in Pseudomonas syringae pv. <i>actinidiae</i> , Facilitating Efficient Temperature-Dependent Effector Translocation

Abstract

Plant diseases—their occurrence and severity—result from the impact of three factors: the host, the pathogen, and the environmental conditions, interconnected in the disease triangle. Time was further included as a fourth factor accounting for plant disease, leading to a more realistic three-dimensional disease pyramid to represent the evolution of disease over time.
