Pectin Methylesterase Is Induced in Arabidopsis upon Infection and Is Necessary for a Successful Colonization by Necrotrophic Pathogens
The ability of bacterial or fungal necrotrophs to produce
enzymes capable of degrading pectin is often related to a
successful initiation of the infective process. Pectin is synthesized
in a highly methylesterified form and is subsequently
de-esterified in muro by pectin methylesterase. Deesterification
makes pectin more susceptible to the degradation
by pectic enzymes such as endopolygalacturonases
(endoPG) and pectate lyases secreted by necrotrophic
pathogens during the first stages of infection. We show
that, upon infection, Pectobacterium carotovorum and Botrytis
cinerea induce in Arabidopsis a rapid expression of
AtPME3 that acts as a susceptibility factor and is required
for the initial colonization of the host tissue
