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.

The invention provides targets coated with structured biological materials, which are employed in laser produced plasma systems. The biological materials selected from cells of microbial, protozoan or plankton origin are applied on a portion of a solid target, like polished glass plate which then form a target system that absorbs the intense laser pulses, generates hot dense plasma and results in the emission of the X-rays. The method of coating structured biomaterial decreases the usable laser intensity required for producing the hot plasma, while increasing the X-ray yield. The coatings are easy to prepare and it is possible to vary the nature and shape of the cellular material in order to control/regulate the interaction with the light and thereby optimize the resultant plasma generation and X-ray emission. The increase in temperature of the plasma and the increase in yield demonstrate that the method is suitable for enhancing the emission yield in the Ultra Violet, Extreme Ultra violet, x-ray and the hard x-ray regimes.
