1. A method of producing a genome-edited plant, wherein the plant is a petunia, the method comprising:
introducing a composition into a plant cell
wherein the composition comprises
a Cas protein, or a nucleic acid sequence encoding the same, wherein the Cas protein is the Streptococcus pyogenes-derived Cas9 protein; and
a guide RNA having a first portion complementary to about 20nt of a target sequence and a second portion capable of interacting with the Cas protein, or a nucleic acid sequence encoding the guide RNA,
wherein the target sequence is a part of sequence of F3H gene on genomic DNA in a petunia and is selected from SEQ ID NOs: 2, 3, 4, and 5 of the F3H gene,
wherein the guide RNA is selected from the group consisting of SEQ ID NO: 43, 44, 45, and 46, which is corresponding to the target sequence of SEQ ID NOS: 2, 3, 4, and 5, respectively,
wherein the plant cell is a protoplast form, and the composition induces an indel by cleaving one or more sequences selected from SEQ ID NOs: 2, 3, 4, and 5 on the genomic sequencing encoding F3H in the plant cell,
obtaining an engineered plant cell which comprises an artificial mutation on the genome of the plant cell, and
regenerating the engineered plant cell to be the genome-edited plant,
wherein the genome-edited plant has a changed color characteristic compared to a wild type thereof.
