Abstract
The present invention relates to rice grain with thickened aleurone. Also provided is a rice plant comprising at least one genetic variation which reduces the activity of at least one ROS1a gene in the plant. Grain of the invention, or aleurone therefrom, has improved nutritional properties, and hence is particularly useful for human and animal feed products.
Claims9
A rice grain comprising an aleurone, a starchy endosperm and a mutant ROS1a gene which encodes a ROS1a polypeptide, wherein the grain is homozygous for the mutant ROS1a gene, and wherein the ROS1a polypeptide comprises an amino acid sequence which is identical to SEQ ID NO:
- 1, or comprises an amino acid substitution which is S156F, S214F, S1413N, A441V, S1357F, K501S or R482K with reference to SEQ ID NO:
- 2.
