Pistil elimination in staminate florets requires jasmonic acid signaling, and functional pistils are protected by the action of the silkless 1 (sk1) gene. The sk1 gene was identified and found to encode a previously uncharacterized family 1 uridine diphosphate glycosyltransferase that localized to the plant peroxisomes. Constitutive expression of an sk1 transgene protected all pistils in the plant, causing complete feminization, a gain-of-function phenotype that operates by blocking the accumulation of jasmonates. The segregation of an sk1 transgene was used to effectively control the production of pistillate and staminate inflorescences in maize plants. application/pdf https://sonar.ch/global/documents/239277 eng info:eu-repo/semantics/altIdentifier/doi/10.1126/sciadv.1600991 info:eu-repo/semantics/altIdentifier/pmid/27819048 info:eu-repo/semantics/openAccess Science advances. - 2016 Floral development UDP-glycosyltransferase jasmonic acid plant hybrids sex determination silkless 1 gene Cyclopentanes Glycosyltransferases Inflorescence Oxylipins Peroxisomes Plant Proteins Zea mays Control of sexuality by the sk1-encoded UDP-glycosyltransferase of maize. http://purl.org/coar/resource_type/c_6501
