In planta transcriptomics reveals conflicts between pattern-triggered immunity and the AlgU sigma factor regulon.

In previous work, we determined the transcriptomic impacts of flg22 pre-induced Pattern Triggered Immunity (PTI) in Arabidopsis thaliana on the pathogen Pseudomonas syringae pv.tomato DC3000 (Pto).During PTI exposure we observed expression patterns in Pto reminiscent of those previously observed Coaster Set in a Pto algU mutant.AlgU is a conserved
