Abstract
Temperature is one of the most prominent environmental factors that influence plant immunity. Depending on the plant-pathogen system, increased temperature may inhibit or enhance disease resistance or immunity in plants. Measuring the effect of temperature on plant immunity is the first step toward revealing climate effects on plant-pathogen interactions and molecular regulators of temperature sensitivity of plant immunity. Quantification of plant disease resistance or susceptibility under different temperatures can be accomplished by assessing pathogen growth over time in infected plants or tissues. Here, we present a protocol for quantifying pathogen growth in the most studied system of Arabidopsis thaliana and Pseudomonas syringae pathovar tomato (Pst) DC3000. We discuss important factors to consider for assaying pathogen growth in plants under different temperatures. This protocol can be used to assess temperature sensitivity of resistance in different plant genotypes and to various pathovars.
