Abstract
The invention relates to the novel use of a sequence coding for a protein capable of degrading oxalic acid to select plant cells which have integrated a gene of interest, and a novel process for selecting, on oxalic acid, cells, calluses or plants transformed by this recombinant DNA.
Claims8
A process for selecting plant cells comprising the steps of:
- transforming plant cells with a DNA sequence coding for an enzyme having oxalate oxidase activity and having a homology of at least 80% with SEQ ID No. 1, and
- selecting the plant cells which express said enzyme.
