摘要: A number of plant pathogenic and symbiotic microbes produce specialized cellular structures that invade host cells where they remain enveloped by host-derived membranes. The mechanisms underlying the biogenesis functions host–microbe interfaces are poorly understood. Here, we show late endocytic trafficking is diverted toward extrahaustorial membrane (EHM); a host–pathogen interface develops in invaded Irish potato famine pathogen Phytophthora infestans. endosome tonoplast marker protein Rab7 GTPase RabG3c, but not tonoplast-localized sucrose transporter, recruited to EHM, suggesting specific rerouting vacuole-targeted endosomes interface. We revealed dynamic nature this process showing that, upon activation, cell surface immune receptor traffics haustorial Our work provides insight into EHM reveals processes recruit compartments receptors
