There is a sequence difference between male and hermaphrodite SHORT VEGETATIVE PHASE (CpSVP), making SVP a strong candidate gene controlling peduncle length in papaya. To study the spatial and temporal expression and function of CpSVP in Arabidopsis, we constructed a translation fusion structure based on the native promoter of SVP in papaya. In the 2kb promoter, strong GUS staining was observed in the floral organs and pedicels. In the 1kb promoter, there is no GUS expression in the floral organs, and it is barely detectable in pedicels. Removal of a GA responsive P-box cis-element in the 1kb promoter enhanced expression in the floral organs and pedicels, and elongated pedicels. In the transgenic Arabidopsis plants expressing the male CpSVP allele, there was an increase in pedicel length, but not in the plants expressing the hermaphrodite CpSVP allele. CpSVP-Y is capable of pedicel elongation, with no defects in reproductive organs. These findings imply that CpSVP-Y and this P-box play a major role in peduncle elongation but not sex determination in papaya.<\/jats:p>","DOI":"10.3390\/plants15020209","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T09:25:02Z","timestamp":1767950702000},"page":"209","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Identification of a GA-Related Cis-Element Regulating Male Peduncle Elongation in Papaya"],"prefix":"10.3390","volume":"15","author":[{"given":"Julie","family":"Nguyen-Edquilang","sequence":"first","affiliation":[{"name":"FAFU and UIUC-SIB Joint Center for Genomics and Biotechnology, Fujian Provincial Key Laboratory of Haixia Applied Plant Systems Biology, Fujian Agriculture and Forestry University, Fuzhou 350002, China"},{"name":"Department of Plant Biology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingjing","family":"Yue","sequence":"additional","affiliation":[{"name":"FAFU and UIUC-SIB Joint Center for Genomics and Biotechnology, Fujian Provincial Key Laboratory of Haixia Applied Plant Systems Biology, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9417-5789","authenticated-orcid":false,"given":"Ray","family":"Ming","sequence":"additional","affiliation":[{"name":"FAFU and UIUC-SIB Joint Center for Genomics and Biotechnology, Fujian Provincial Key Laboratory of Haixia Applied Plant Systems Biology, Fujian Agriculture and Forestry University, Fuzhou 350002, China"},{"name":"Department of Plant Biology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13710","DOI":"10.1073\/pnas.1207833109","article-title":"Sequencing Papaya X and Yh Chromosomes Reveals Molecular Basis of Incipient Sex Chromosome Evolution","volume":"109","author":"Wang","year":"2012","journal-title":"Proc.
