Phenotypic comparisons of vegetative organs between wild-type, osku70 mutant, and OsKu70 transgenic plants. A, Growth retardation of osku70 homozygous mutant seedlings. Wild-type, heterozygous (G2 and G3) and homozygous (G2 and G2-1) osku70-1 and osku70-2 mutant, and 35S:anti-OsKu70 (T2; lines 5 and 8) and 35S:OsKu70 (T2; lines 1 and 5) transgenic seedlings were germinated and grown in half-strength Murashige and Skoog medium for 10 d under normal-light growth conditions. B, Gross morphology of 3-month-old wild-type, heterozygous (G2 and G3) and homozygous (G2 and G2-1) osku70-1 and osku70-2 mutant, and 35S:OsKu70 (T2; lines 1 and 5) and 35S:anti-OsKu70 (T2; lines 5 and 8) transgenic rice plants, which were grown under greenhouse conditions.
