Also we have almost a mini special issue on bacterial nutrition strategies during plant Xanthomonas infection.
Firstly, Wang et al investigate how bacteria use xanthosan to feed themselves and develop a strategy to exploit this for resistance:

A bacterial nutrition strategy for plant disease control
Xanthomonas spp. cause serious diseases in more than 400 plant species. The conserved AvrBs2 family effectors are among the most important virulence factors in xanthomonads, but how AvrBs2 promotes in...

Sure, but it’s still early days and this was the first bacterial plant pathogen sequenced (as far as I know, though some Xanthomonads and Xylella appeared soon after). We plant pathologists do crave a bit of recognition! 😉

The Type II secreted subtilase IssA in Dyella japonica MF79 cleaves flg22 and AtPEP1 peptides in vitro and suppresses plant immune activation. IssA homologs are well-conserved, especially Xanthomonads.

A type II secreted subtilase from commensal rhizobacteria cleaves immune elicitor peptides and suppresses flg22-induced immune activation
Eastman, Jiang, and Ficco et al. screen 165 root-associated bacteria for suppression of plant immune activation and growth restriction induced by the peptide immune elicitor flg22. They show that Dyella japonica uses the type II secreted subtilase IssA to cleave the peptide immune elicitors flg22 and AtPEP1 and suppress plant immune activation.
