Ideal plant architecture optimizes spatial utilization, enhances economic coefficient, and facilitates mechanized cultivation. In this study, we identified a dwarf mutant, <jats:italic>csdw3<\/jats:italic>, exhibiting reduced plant height, shortened internodes, and fewer internodes. Genetic analysis showed that this dwarf phenotype is controlled by a single recessive gene. Fine\u2010mapping localized the causal locus to an 80\u2009kb region on chromosome 1, where we discovered a 102\u2009bp deletion in <jats:italic>CsCLV2<\/jats:italic>, a gene encoding a leucine\u2010rich repeat receptor\u2010like protein homologous to <jats:italic>Arabidopsis CLAVATA2<\/jats:italic>. CRISPR\u2010Cas9\u2010generated loss\u2010of\u2010function mutants recapitulated the dwarf phenotype, confirming the role of <jats:italic>CsCLV2<\/jats:italic> in plant height regulation. Histological examination revealed that <jats:italic>CsCLV2<\/jats:italic> disruption causes premature termination of shoot apical meristem (SAM) development, reducing both internode number and length. Protein interaction assays further demonstrated that <jats:italic>CsCLV2<\/jats:italic> associates with receptor\u2010like kinase <jats:italic>CsCIK1<\/jats:italic> (<jats:italic>CLAVATA3 INSENSITIVE RECEPTOR KINASES 1<\/jats:italic>), indicating their cooperative function in the <jats:italic>CLV<\/jats:italic>\u2010<jats:italic>WUS<\/jats:italic> signaling pathway to maintain meristem activity. Our findings uncover a regulator of plant height in cucumber and provide valuable genetic resources for breeding ideotypes optimized for yield and cultivation efficiency.<\/jats:p>","DOI":"10.1111\/tpj.70525","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T07:16:04Z","timestamp":1760685364000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Loss
