METHOD FOR SELECTION OF CELL LINES OF PLANTS WITH CHANGED NITRATE REDUCTASE TYPE AND NITRATE FIXATION PATTERN

摘要

A method for selection of cell lines of plants with a changed nitrate reductase type and nitrate fixation pattern includes isolating resistant clones by direct breeding on a model medium. In the model medium a combination of nitrates, as the only nitrogen form, and of anions of a wolframate (W6+) in the concentrations toxic for cell cultures of wild type is used.
