The results indicate that hrpRS and hrpL are part of a regulatory cascade in which HrpR and HrpS activate expression of hrpL and HrpL , a putative sigma factor , induces expression of HrpL - responsive genes .
 GENE: hrpRS; GENE: hrpL; GENE: HrpR; GENE: HrpS; GENE: hrpL; GENE: HrpL; GENE: sigma factor; GENE: HrpL - responsive genes
