Genome Editing to Produce Knockout Mutations of Seed Dormancy Genes in Wheat

Methods Mol Biol. 2024:2830:137-148. doi: 10.1007/978-1-0716-3965-8_13.

Abstract

Knockout mutants provide definitive information about the functions of genes related to agronomic traits, including seed dormancy. However, it takes many years to produce knockout mutants using conventional techniques in polyploid plants such as hexaploid wheat. Genome editing with sequence-specific nucleases is a promising approach for obtaining knockout mutations in all targeted homoeologs of wheat simultaneously. Here, we describe a procedure to produce a triple recessive mutant in wheat via genome editing. This protocol covers the evaluation of gRNA and Agrobacterium-mediated transformation to obtain edited wheat seedlings.

Keywords: Agrobacterium-mediated transformation; CRISPR/Cas9; Genome editing; Immature embryo; Wheat.
