The bacterial pathogen Pseudomonas syringae is a model for exploring the functional structure of such repertoires. The pangenome of P. syringae encodes 57 families of effectors injected by the type Ill secretion system. Distribution of effector genes among phylogenetically diverse strains reveals a small set of core effectors targeting antimicrobial vesicle trafficking and a much larger set of variable effectors targeting kinase-based recognition processes. Complete disassembly of the 28-effector repertoire of a model strain and reassembly of a minimal functional repertoire reveals the importance of simultaneously attacking both processes. These observations, coupled with growing knowledge of effector targets in plants, support a model for coevolving molecular dialogs between effector repertoires and plant immune systems that emphasizes mutually-driven expansion of the components governing recognition. specialized effector-triggered immunity PAMP-triggered immunity nonhost resistance hypersensitive response pathogenicity 076 20 4 199-208 2012 0966-842X https://www.documentation.ird.fr/hor/fdi:010055844 10.1016/j.tim.2012.01.003 0966-842X [F B010055844] https://www.documentation.ird.fr/hor/fdi:010055844 https://www.documentation.ird.fr/intranet/publi/2012/05/010055844.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-06-01 2017-08-23 fdi:010055844 fre
