CONTROLLED GENE EXPRESSION IN PLANTS

摘要

This invention relates to the control of gene expression in plants using either a chimeric transcriptional activator protein system, or a system based on suppressor tRNAs. Furthermore, the invention relates to transgenic plants carrying a DNA molecule coding the transactivator protein or a DNA molecule comprising the gene of interest combined with Lac repressor-responsive elements, crossing of a transgenic plant carrying a gene of interest under control of a Lac repressor/transactivator-sensitive promoter element with a transgenic plant coding for a Lac repressor/transactivator protein and transactivation of expression of a gene of interest.
