The ectopic overexpression of a citrus gibberellin 20-oxidase enhances the non-13-hydroxylation pathway of gibberellin biosynthesis and induces an extremely elongated phenotype in... por Vidal, Ana M., Gisbert, C., Talón, Manuel, Primo-Millo, Eduardo, Lopez-Diaz, I., García-Martínez, José Luis

“…Transgenic plants of Nicotiana tabacum overexpressing a gibberellin (GA) 20-oxidase cDNA (CeGA20ox1) from citrus, under the control of the 35S promoter, mere taller (up to twice) and had larger inflorescences and longer flower peduncles than those of control plants, Hypocotyls of transgenic seedlings were also longer (up to 4 times), and neither the seedlings nor the growing plants elongated further after application of GA(3), Hypocotyl and stem lengths were reduced by application of paclobutrazol, and this inhibition was reversed by exogenous GA(3). …”
