Abstract
This invention relates to compositions and methods for modifying Brassinosteroid Insensitive-1 (BRI1) genes in plants by introducing at least one mutation in a region of the BRI1 gene encoding the kinase domain, optionally to improve yield traits. The invention further relates to a mutated BRI1 gene, a modified BRI1 polypeptide, and plants having increased improved yield traits produced using the methods and compositions of the invention.
Claims13
A plant or part thereof comprising at least one mutation in an endogenous Brassinosteroid Insensitive-1 (BRI1) gene encoding a BRI1 polypeptide (brassinosteroid receptor polypeptide) comprising a kinase domain, wherein the at least one mutation is in a region of the endogenous BRI1 gene that encodes the kinase domain, and
- wherein the plant or part thereof is a corn plant or part thereof.
A modified Brassinosteroid Insensitive-1 (BRI1) polypeptide having at least 80% sequence identity to any one of SEQ ID NOs:
- 71, 87, 88, 101, the modified BRI1 polypeptide comprising a mutation in an amino acid residue located:
- from position 955-975 with reference to amino acid position numbering of SEQ ID NO:71, from position 1023-1043 with reference to amino acid position numbering of SEQ ID NO:87 or SEQ ID NO:88, from position 1081-1101 with reference to amino acid position numbering of SEQ ID NO:101, from position 1065-1085 with reference to amino acid position numbering of SEQ ID NO:114, and/or from position 1026-1046 with reference to amino acid position numbering of SEQ ID NO:
- 125.
