The invention discloses a method for acquiring an
aromatic rice strain by targeting a Badh2
gene via
CRISPR / Cas9
gene editing technology. The method comprises the following steps: separately targeting sequences, recognizable by Cas9, of every
exon and
intron of an aromatic
gene by using the
CRISPR / Cas9 gene editing technology and then
cutting a
genomic DNA sequence to initiate
DNA restoration so as to obtain an afunctional Badh2 gene; with the
callus of Indica rice,
japonica rice or glutinous rice as a
receptor material of genetic transformation and an mature
embryo, young ear,
ovary or the like as explant, carrying out induction so as to obtain a diploid
callus, introducing a targeting vector into cells of the
callus by using an
Agrobacterium mediated transformation method, screening and identifying positive plants and separating the plants from a T1 colony so as to obtain an
aromatic rice strain; and with anther,
pollen, unfertilized
ovary or the like as explant, carrying out induction so as to obtain a haploid callus, introducing the targeting vector into cells of the callus by using the
Agrobacterium mediated transformation method, screening a positive callus, reduplicating the positive callus by using
colchicine, carrying out differentiation to form seedlings and identifying genetic transformation positive plants so as to eventually obtain the
aromatic rice strain.
