摘要： Dwarf mutations have played vital roles in elucidating the regulatory molecular mechanisms of plant height. In this study, we identified a mutant named Csdw, whose mutagenesis was induced by ethyl methyl sulfonate in cucumber, and this mutant exhibited a dwarf phenotype with a reduced internode length because of the reduction of cell division in the main stem. The dwarf phenotype of Csdw could be partially rescued through GA(3) application, and endogenous GA(3) levels from the stem of Csdw decreased distinctly. Genetic analysis showed that Csdw was attributed to a recessive gene. The MutMap and Kompetitive Allele Specific PCR genotyping results revealed that Csa3G872760 (CsCLAVATA1), encoding a CLAVATA1-type receptor-like kinase, was a putative candidate gene for dwarf mutation in cucumber. The expression of CsCLAVATA1 in the stem of Csdw was lower than that of wild-type plants. Therefore, CsCLAVATA1 could regulate the dwarf phenotype in cucumber.
