New genes which code for amino acid - culturing of specificity for n - acetyl - l - phosphinotricin, their isolation and use

摘要

The invention concerns DNA molecules which code for deacetylases or proteins having the biological activity of a deacetylase, and transgenic plant cells which are transformed with the DNA molecules according to the invention. These molecules can be used to produce plants having parts which can be deliberately destroyed, that is plants which have male or female sterility, by the specific expression of a deacetylase gene.
