Cereals with altered dormancy
First Claim

1. A wheat plant which has a genetic variation that decreases ABA 8′
- -hydroxylase activity in the grain of the wheat plant, wherein said genetic variation comprises two mutations of which one mutation is in a first ABA 8′
-hydroxylase-1 gene and one mutation is in a second ABA 8′
-hydroxylase-1 gene of the plant, wherein the mutations are in the A and B genomes, the A and D genomes or the B and D genomes of the wheat plant, such that the ABA 8′
-hydroxylase activity is decreased in the grain of the plant and the grain of the plant has a rate of germination that is decreased relative to grain of a corresponding wheat plant which does not have the genetic variation.

Abstract
The present invention relates to polypeptides, and polynucleotides encoding therefor, which influence seed dormancy in cereals such as wheat and barley. In particular, the present invention relates to polypeptides with ABA 8′-hydroxylase activity, and polynucleotides encoding these proteins. Also provided are cereal plants which produce seeds that have altered rates of germination, and/or levels of dormancy, when compared to seeds from wild-type plants, as well as methods of producing such plants.
