Transcriptome analyses of mock- and Pst DC3000-inoculated Arabidopsis thaliana Col-0 plants at normal and elevated temperature


ABSTRACT: We performed RNA sequencing of mock-inoculated and Pseudomonas syringae pv. tomato (Pst) DC3000-infected A. thaliana (Col-0 accession) plants at normal (23C) and elevated (30C) temperatures. 4-week-old Col-0 plants were pre-incubated at 23C and 30C for 48h and then leaves were syringe-infiltrated with either mock (MgCl2) or DC3000 bacterial inoculum. Plants were incubated at their respective temperatures (23C or 30C) for another 24h post-inoculation before tissue collection for RNA extraction. RNA samples for submitted for RNA sequencing and we found different clusters of DC3000-regulated genes that were downregulated, upregulated and unchanged at elevated temperature. Temperature-downregulated DC3000-induced genes were enriched for a whole suite of defense-related genes, including those essential for host salicylic acid (defense hormone) biosynthesis and accumulation.
