Abstract
The present invention provides methods for increasing yield in plants by introducing a gene encoding phosphinothricin acetyltransferase. The invention further involves a method of transferring said increased yield phenotype to other lines of plants by crossing. A maize transformant is identified in which the phosphinothricin acetyltransferase gene integration event is correlated with increased yield.
Claims19
A method of providing a transformed plant line having an increased yield relative to a starting plant line, comprising introducing into a starting plant line a gene encoding phosphinothricin acetyltransferase (PAT) to produce PAT transformed plants, and selecting therefrom a PAT transformed plant having an increased yield relative to the starting plant line.
A method of preparing a PAT gene integration event DNA segment comprising the steps of:
- (a) identifying a plant containing a transgenic PAT gene;
- (b) preparing a genomic library from said identified plant;
- and
- (c) screening said library to identify a genomic clone comprising the PAT gene and adjacent plant genomic DNA.
