Abstract
The present invention provides methods for obtaining plants that exhibit useful traits by transient suppression of the MSH1 gene of the 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.
Claims24
A method for producing a plant exhibiting a useful trait comprising the steps of:
- a. suppressing expression of MSH1 gene(s) in a first parental plant or plant cell;
- b. outcrossing the parental plant of step (a), progeny of said parental plant of step (a), a plant obtained from said plant cell of step (a), or progeny of a plant obtained from said plant cell of step (a) to a second plant wherein MSH1 had not been suppressed;
- c. screening a population of progeny plants obtained from said outcross of step (b) for at least one useful trait, wherein a portion of said population of progeny plants express MSH1;
- and,
- d. selecting a progeny plant having a useful trait that exhibits nuclear inheritance, wherein said trait is not caused by substoichiometric shifting (SSS) in mitochondria of the selected progeny plant and wherein said selected progeny plant expresses MSH1, thereby producing a plant exhibiting a useful trait.
The method of claim 140, wherein said trait is male sterility.
