Recent studies have revealed a concerted function of salicylic acid (SA) and N-hydroxypipecolic acid (NHP) in the establishment of SAR against bacterial pathogens, but it remains unknown whether NHP is also involved in SAR against viruses. We found that the local application of acibenzolar-S-methyl (ASM), a synthetic analog of SA, suppressed plantago asiatica mosaic virus (PlAMV) infection in the distal leaves of Arabidopsis thaliana. This suppression of infection in untreated distal leaves was observed at 1 day, but not at 3 days, after application. ASM application significantly increased the expression of SAR-related genes, including PR1, SID2, and ALD1 after 1 day of application. Viral suppression in distal leaves after local ASM application was not observed in the sid2-2 mutant, which is defective in isochorismate synthase 1 (ICS1), which is involved in salicylic acid synthesis; or in the fmo1 mutant, which is defective in the synthesis of NHP; or in the SA receptor npr1-1 mutant. Finally, we found that the local application of NHP suppressed PlAMV infection in the distal leaves. These results indicate that the local application of ASM induces antiviral SAR against PlAMV through a mechanism involving NHP.<\/jats:p>","DOI":"10.3390\/ijms25031808","type":"journal-article","created":{"date-parts":[[2024,2,2]],"date-time":"2024-02-02T09:24:08Z","timestamp":1706865848000},"page":"1808","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Local Application of Acibenzolar-S-Methyl Treatment Induces Antiviral Responses in Distal Leaves of Arabidopsis thaliana"],"prefix":"10.3390","volume":"25","author":[{"given":"Seiya","family":"Ito","sequence":"first","affiliation":[{"name":"Graduate School of Agriculture, Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kagari","family":"Sakugawa","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fawzia","family":"Novianti","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4604-6608","authenticated-orcid":false,"given":"Tsutomu","family":"Arie","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"},{"name":"Institute of Global Innovation Research (GIR), Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Komatsu","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"},{"name":"Institute of Global Innovation Research (GIR), Tokyo University of Agriculture and Technology (TUAT), Fuchu 183-8509, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1016\/j.tplants.2021.08.012","article-title":"Plant Immune Networks","volume":"27","author":"Ngou","year":"2022","journal-title":"Trends Plant Sci."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1234","DOI":"10.1111\/nph.16953","article-title":"Systemic Propagation of Immunity in Plants","volume":"229","author":"Vlot","year":"2021","journal-title":"New Phytol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1016\/j.pbi.2020.10.004","article-title":"Mobile Signals in Systemic Acquired Resistance","volume":"58","author":"Kachroo","year":"2020","journal-title":"Curr.
