    Genome editing in rice using SpCas9, ScCas9 and SpCas9-LK variants. A, Schematic illustration of ScCas9 and SpCas9-LK variants. U3, U3 promoter; NLS, nuclear localization signal; CaMV T, cauliflower mosaic virus 35S terminator; OsActin P, OsActin promoter. Loop (367–376, IKHRKRTTKL) and KQ (1337–1338) are two important insertions in ScCas9. B, Mutation frequency of SpCas9, ScCas9 and SpCas9-LK at NNG PAM target sites in transgenic calli and mutation frequency of ScCas9 in seedlings. The PAM motif is in red and underlined, and the flanking sequence around the PAM motif is in blue. Bi, biallele; He, heterozygote; Chi, Chimera.
