摘要:
A method of and plasmids for producing specific gene expression in the guard cells of plants. In particular, 5' transcriptional regulatory promoter regions are provided for guard cell specific expression. In addition, methods for preparing an expression cassette, plasmids, and the use of the cassettes and plasmids to produce transgenic plant cells and plants are described.
摘要:
There is disclosed plasmids for the preparation of transgenic plants, as well as the plants, that are modified through the transfer and the expression of genes influencing the sugar metabolism or the sugar partitioning within a plant, which are localised on these plasmids.The transferred genes cause a modified distribution of assimilates in the transgenic plant which result in significant changes in habit, such as size, leaf shape, internode separation and root formation, as well as improvements in yield.Plasmids are also described which enable foreign proteins to be directed into the vacuoles of transgenic plants.
摘要:
There is described a new DNA sequence of an expression cassette on which the potato tuber specific regulatory regions are localised as well as the transfer of this DNA sequence into the plant genome using agrobacteria as transfer micro-organisms. The DNA sequence contains a patatin gene with a patatin gene promoter. The transfer DNA sequence acts both for regulating endogenous as well as for preparation of heterologous products in crops.
