Abstract excerpt
Although plant pan-genome studies have revealed extensive copy number variations, their phenotypic consequences remain poorly understood. Here, we manipulated the copy number of OsMADS18 in rice (Oryza sativa) cv 'Hitomebore' using the CRISPR/Cas9 system. We established rice lines harboring one to three tandem copies of OsMADS18, as identified by quantitative PCR and sequencing. The presence of one to three...
