DNA plasmid comprising phytostene synthesise gene, as well as methods to improve the selection of transgenic plants and to reduce the number of copies of plant cell transgene

摘要

"DNA constructs and methods to improve the production of commercially viable transgenic plants." This invention refers to a non-lethal negative selectable marker gene in the DNA of the skeleton vector of a DNA plasmid used to transform plant cells. thistransgenes are designed to express a non-lethal gene product in plant cells that contains DNA from the skeleton of DNA plasmid vector. the non-lethal selectable negative marker gene products are involved in plant hormone biosynthesis pathwaysfun of plant hormone substrate, plant hormone degradation, plant hormone signalling or metabolic interference. The use of these DNA plasmids to transform plant cells provides improved production of commercially viable plants.
