    Abstract: In a transgenic plant, a stress-responsive promoter containing CE3 and ABRE2 from HVA1 ABRC3 and CE1 from HVA22 ABRC1, directs low background expression of a gene under normal growth conditions, but is highly inducible by an abiotic stress, such as abscisic acid, dehydration, salt or cold. Compared with the wild type plant, the transgenic plant that expresses a stress-resistant gene under the control of the stress-responsive promoter is more resistant and/or tolerant to abiotic stresses and exhibits similar or higher growth rate and strength under regular or normal environmental conditions.

    Abstract: Novel gibberellin 2-oxidase (GA2ox) genes were identified. Differential expression of GA2ox genes correlated with flower development, seed germination, tiller growth and other developmental processes. In addition, the early and increased growth of tiller and adventitious root and altered root architecture caused by overexpression of GA2oxs further suggest the pleiotropic role of GA2oxs in controlling growth and architecture in plants such as rice. GA2ox5, GA2ox6 and GA2ox9 were three genes encoding class C20 GA2oxs in rice. Mutants or transgenic rice overexpressing class C20 GA2oxs exhibited a broad range of mutant phenotypes, including semi-dwarfism, increased root system and higher tiller numbers that may favor grain yield. Mutations in the conserved domain III were found to affect the physiological activity of class C20 GA2oxs. Methods are described for controlling plant growth and architecture by controlling gene expression of gibberellin 2-oxidase in the plant.
