One of the largest and so far understudied microbial protein families of effectors is necrosis- and ethylene-inducing peptide-1-like proteins (NLPs), which are involved in important plant diseases. Many NLPs act as cytolytic toxins that cause cell death and tissue necrosis by disrupting the plant\u2019s plasma membrane. Their mechanism of action is unique and leads to the formation of small, transient membrane ruptures. Here, we capture the interaction of the cytotoxic model NLP from the oomycete\u00a0<i>Pythium aphanidermatum<\/i>, NLP<sub>Pya<\/sub>, with plant cell-mimicking membranes of giant unilamellar vesicles (GUVs) and tobacco protoplasts using confocal fluorescence microscopy. We show that the permeabilization of GUVs by NLP<sub>Pya<\/sub>\u00a0is concentration- and time-dependent, confirm the small size of the pores by observing the inability of NLP<sub>Pya<\/sub>\u00a0monomers to pass through them, image the morphological changes of GUVs at higher concentrations of NLP<sub>Pya<\/sub>\u00a0and confirm its oligomerization on the membrane of GUVs. In addition, NLP<sub>Pya<\/sub>\u00a0bound to plasma membranes of protoplasts, which showed varying responses. Our results provide new insights into the interaction of NLP<sub>Pya<\/sub>\u00a0with model lipid membranes containing plant-derived sphingolipids.<\/p>\n","protected":false},"featured_media":0,"template":"","products_tags":[129],"resource_type":[75],"application_areas":[53,99],"therapeutic_areas":[143],"target_categories":[341],"target_families":[],"targets":[],"resource_keyword":[],"class_list":["post-16740","resource_library","type-resource_library","status-publish","hentry","products_tags-vesicle-prep-pro","resource_type-publication","application_areas-assay-development-and-validation","application_areas-pores-and-toxins","therapeutic_areas-assay-development-and-validation","target_categories-pores-and-toxins"],"acf":[],"_links":{"self":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library\/16740","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library"}],"about":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/types\/resource_library"}],"wp:attachment":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/media?parent=16740"}],"wp:term":[{"taxonomy":"products_tags","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/products_tags?post=16740"},{"taxonomy":"resource_type","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_type?post=16740"},{"taxonomy":"application_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/application_areas?post=16740"},{"taxonomy":"therapeutic_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/therapeutic_areas?post=16740"},{"taxonomy":"target_categories","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_categories?post=16740"},{"taxonomy":"target_families","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_families?post=16740"},{"taxonomy":"targets","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/targets?post=16740"},{"taxonomy":"resource_keyword","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_keyword?post=16740"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
