Method for increasing plant yields

摘要

The present invention provides methods for obtaining plants that exhibit useful traits by expression of a DNA methyltransferase fusion protein in progenitor plants. Methods for identifying genetic loci that provide for useful traits in plants and plants produced with those loci are also provided. In addition, plants that exhibit the useful traits, parts of the plants including seeds, and products of the plants are provided as well as methods of using the plants. Recombinant DNA vectors and transgenic plants comprising those vectors that express a DNA methyltransferase fusion protein are also provided.

主权项

1. A method of increasing cytosine methylation at one or more targeted DNA sequences in a plant or plant cell comprising the steps of:
a. expressing in a plant or plant cell a DNA methyltransferase fusion protein comptising a DNA methyltransferase domain and a DNA binding domain that binds one or more targeted DNA sequences in said plant or plant cell; and, b. identifying one or more plants or plant cells, or progeny thereof, with increased DNA methylation at one or more targeted DNA sequences relative to DNA methylation levels of a control plant or plant cell.
