marked gene activation DNA construct, marked population of maize plants, method for generating it and method for generating a marked maize plant

摘要

marked gene activation platform for maize, and resulting labeled populations and plants. The present invention relates to a labeled gene activation construct for maize, the resulting labeled populations and plants. In one example, a tagged gene activation DNA construct includes a transposase coding sequence, a detectable reporter (such as the b-turkey and c1 anthocyanin regulatory genes) and a non-autonomous transposable t-dna cassette. for example, the transposable t-dna cassette is inserted into the detectable reporter coding region so that the b-turkey and c1 genes express anthocyanins in a cell containing the corn labeled gene activation dna construct only by excision of the cassette transposable. Methods for generating the marked population of maize plants include transforming a maize plant cell or tissue with the constructs presented.
