Guanfacine and clonidine markedly reduced ethephon-enhanced leaf abscission, but had little effect on ethephon-enhanced fruit loosening. Ethephon-enhanced fruit and leaf ethylene production, and ACC concentration in fruit abscission zones, fruit peel, leaf abscission zones, and leaf blades were decreased by guanfacine. Guanfacine reduced ethephon-enhanced expression of ACS1 and ACO genes in leaf abscission zones and blades, but to a lesser extent in fruit abscission zones. The expression pattern of the ACS2 gene, however, was not associated with abscission. The results demonstrate that differential expression of ACS1 and ACO genes is associated with reduction of ethephon-enhanced leaf abscission by guanfacine, and suggest a link between G-protein-related signalling and abscission.","is_dataset_classified":null,"base_score":3.5263605246161616,"endowment":3.5263605246161616,"datacite_reuse_total":8,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15928018","pmcid":null,"openalex_id":"https://openalex.org/W2144402425","authors":[],"funders":[],"total_grants":0,"fwci":3.2745,"citation_percentile":0.92132045,"influential_citations":1,"citation_trend":[{"year":2012,"count":2},{"year":2013,"count":1},{"year":2014,"count":1},{"year":2015,"count":2},{"year":2016,"count":1},{"year":2017,"count":3},{"year":2019,"count":1},{"year":2020,"count":1},{"year":2022,"count":2},{"year":2024,"count":4},{"year":2025,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://academic.oup.com/jxb/article-pdf/56/417/1867/1309248/eri176.pdf","host_type":"BRONZE"},{"url":"http://academic.oup.com/jxb/article-pdf/56/417/1867/1309248/eri176.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1093/jxb/eri176","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15928018","host_type":"repository"}],"fields_of_study":["Postharvest
