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. https://www.cell.com/cell-reports/fulltext/S2211-1247(24)01414-1
