EP 513054
Claim 1 recites a plant cell that comprises both a phosphinothricin resistance gene and a gene coding for a virus resistance. This is a broad claim which is limited by the embodiments cited in the following claims.
The phosphinothricin gene must be obtained from a Streptomyces species, and hence includes the bar gene (Claim 4). Furthermore, the virus resistance gene must code for a virus coat protein and be obtained from RNA of either cucumber mosaic virus, alfalfa mosaic virus or of brom mosaic virus (Claims 2-3). Dependent Claim 5 recites a process for producing plants with the transgenes, as described in Claim 1, that display improved growth after treatment with phosphinothricin. The use of the plant cell for the regeneration of plants, with or without improved herbicide or virus resistance, is also claimed (Claims 6-7).
