Population of transgenic plants individually comprising distinct codogenic gene segments, the population having at least 50% of the codogenic gene segments from a donor organism

Arabidopsis thaliana Saccharomyces cerevisiae The present invention relates to populations of trangenic plants encompassing a substantial part of all codogenic gene segments of a donor organism, and to biological material derived therefrom, plasmid collections and populations of transformed host organisms with which plants can be transformed in a suitable manner. There are also described methods for generating the plants and the material, and the use of the plants and of the material for functional studies. The codogenic gene segments are integrated into the genome of the plants. For example, there are described a population of plants of the species into whose genome the codogenic gene segments from are integrated, and their morphological analysis under normal conditions and stress conditions.
