Abstract
The invention relates to a method for producing an aqueous extract rich in nucleic acids from a plant material, in particular from plant embryos or from seeds rich in DNA or in RNA, which consists in: extracting, in an aqueous medium, the plant material in the presence of cellulolytic enzymes at an initial pH of 9 to 13, separating the plant material in order to recover an aqueous extract, treating the extract with a protease, separating the insolubles in order to recover a purified aqueous extract.
