 === How discovered? ===
-Although no homology was found between XopS and other T3E effectors, //xopS //was putatively identified by the presence of a plant-inducer promoter (PIP) box, a lower GC content suggesting acquisition by HGT, and co-expression with other T3E genes (Schulze //et al.//, 2012). Deficient mutants and overexpression studies revealed that XopB and XopS contribute to disease symptoms and bacterial growth, and suppress plant defense gene expression (Schulze //et al.//, 2012).
