Abstrakt: Pedicel length is a crucial agronomic trait of cucumbers. Fruit deformation can occur When the pedicel is too long or too short. Moreover, an appropriate pedicel length is advantageous for mechanized harvesting. Therefore, it is essential to investigate the molecular regulatory mechanisms underlying cucumber pedicel length. In the current study, we obtained a short pedicel mutant through EMS mutagenesis and discovered that the reduced cell number was the primary cause of the shortened pedicel. Upon analyzing the hormone content, we found that the level of trans zeatin in the long-pedicel material was significantly higher than that in the short-pedicel material. Further transcriptome sequencing analysis revealed that differentially expressed genes were enriched in cytokinin synthesis-related pathways. Based on these results, the present study concluded that cucumber pedicel length is regulated by genes related to the cytokinin synthesis pathway and that differences in length result from differences in zeatin content and cell number.
