In rice, one of the best characterized PRRs is XA21, a leucine rich repeat receptor-like kinase that confers broad-spectrum resistance to multiple strains of the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). In 2009 we reported that an Xoo protein, called Ax21, is secreted by a type I-secretion system and that it serves to activate XA21-mediated immunity. This report has recently been retracted. Here we present data that corrects our previous model. We first show that Ax21 secretion does not depend on the predicted type I secretion systemand that it is processed by the general secretion (Sec) system. We further show that Ax21 is an outer membrane protein, secreted in association with outer membrane vesicles. Finally, we provide data showing that ax21 knockout strains do not overcome XA21-mediated immunity. specialized Xanthomonas Rice XA21 Outer membrane vesicles Secretion PAMPs Plant immunity 076 020 2 e242 [14 p.] 2014 2167-8359 https://www.documentation.ird.fr/hor/fdi:010064619 10.7717/peerj.242 2167-8359 [F B010064619] https://www.documentation.ird.fr/hor/fdi:010064619 https://www.documentation.ird.fr/intranet/publi/2015/00/010064619.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-07-07 2017-08-23 fdi:010064619 fre
