  abstract = {{P}lant disease is a major challenge to agriculture worldwide, and it is exacerbated by abiotic environmental factors. {D}uring some plant-pathogen interactions, heat stress allows pathogens to overcome host resistance, a phenomenon which could severely impact crop productivity considering the global warming trends associated with climate change. {D}espite the importance of this phenomenon, little is known about the underlying molecular mechanisms. {T}o better understand host plant responses during simultaneous heat and pathogen stress, we conducted a transcriptomics experiment for rice plants (cultivar {IRBB}61) containing {X}a7, a bacterial blight disease resistance ({R}) gene, that were infected with {X}anthomonas oryzae, the bacterial blight pathogen of rice, during high temperature stress. {X}a7-mediated resistance is unusual relative to resistance mediated by other {R}genes in that it functions better at high temperatures. {U}sing {RNA}-{S}eq technology, we identified 8,499 differentially expressed genes as temperature responsive in rice cultivar {IRBB}61 experiencing susceptible and resistant interactions across three time points. {N}otably, genes in the plant hormone abscisic acid biosynthesis and response pathways were up-regulated by high temperature in both mock-treated plants and plants experiencing a susceptible interaction and were suppressed by high temperature in plants exhibiting {X}a7-mediated resistance. {G}enes responsive to salicylic acid, an important plant hormone for disease resistance, were down-regulated by high temperature during both the susceptible and resistant interactions, suggesting that enhanced {X}a7-mediated resistance at high temperature is not dependent on salicylic acid signaling. {A} {DNA} sequence motif similar to known abscisic acid-responsive cis-regulatory elements was identified in the promoter region upstream of genes up-regulated in susceptible but down-regulated in resistant interactions. {T}he results of our study suggest that the plant hormone abscisic acid is an important node for cross-talk between plant transcriptional response pathways to high temperature stress and pathogen attack. {G}enes in this pathway represent an important focus for future study to determine how plants evolved to deal with simultaneous abiotic and biotic stresses.},
