CRISPR/Cas9-Mediated Genome Editing in Indica Rice (Oryza sativa L. subsp. indica var. CR-5272)

Methods Mol Biol. 2024:2788:257-271. doi: 10.1007/978-1-0716-3782-1_15.

Abstract

Tissue culture optimization protocols limit indica rice breeding. Such a challenge is vital because emergent techniques still rely on tissue culture methods and could allow the breeding of new varieties with higher production and toleration of adverse environmental effects caused by climate change. Genome editing technology, using CRISPR/Cas9, is a fast and precise method for accelerated plant breeding. It limited its use in indica subspecies because of the recalcitrant response to in vitro culture methods. This chapter describes a protocol for CRISPR/Cas9 editing in indica subspecies, specifically in the CR-5272 variety derived from parental lines IR-822, using Agrobacterium tumefaciens and biolistic transformation.

Keywords: Agrobacterium tumefaciens; Biolistics; CRISPR/Cas9; Embryogenic calli; In vitro regeneration.
