Impact of elevated temperature on immunity-related hormone signaling in tomato plants.
Molecular mechanisms governing the plant-pathogen-environment "disease triangle" are starting to emerge, although less so in agriculturally important species like tomato ( Solanum lycopersicum ). Here we analyzed defence hormone responses of tomato plants infected with the bacterial pathogen Pseudomonas syringae pv. tomato ( Pst ) DC3000 under two different temperatures. Our results showed that tomato plants exhibited temperature-sensitive expression of marker genes associated with salicylic acid (SA), jasmonic acid (JA) and abscisic acid (ABA) pathways, but not ethylene (ET). Our findings highlight the complexity of plant-microbe interactions and the importance of considering environmental conditions when studying plant defence responses.
