Live-cell imaging highlighted rearrangements in plant cell membranes upon infection. In particular, the tonoplast appeared close to the extrahaustorial membrane surrounding the haustorium. We investigated the subcellular localization patterns of Hpa RxLR effector candidates (HaRxLs) in planta. This subcellular localization screening led to the identification of an extrahaustorial membrane-localized effector, HaRxL17 that when stably expressed in Arabidopsis increased plant susceptibility to Hpa during compatible and incompatible interactions. Here, we report that the N-terminal part of HaRxL17 is sufficient to target Plant signaling & behavior145-9https://www.ebi.ac.uk/biostudies/studies/S-EPMC3357357biostudies-literatureCharacterization of the membrane-associated HaRxL17 Hpa effector candidate.PMC3357357Jones JDPiquerez SJCaillaud MCfalseCharacterization of the membrane-associated HaRxL17 Hpa effector candidate.We examined changes to subcellular architecture during the compatible interaction between the biotroph pathogen Hyaloperonospora arabidopsidis (Hpa) and its host Arabidopsis.
