Phenotypes associated with mutations generated by CAS9 (A) and BECAS9 (B). WT = wild type, Oscao1 = mutant induced by CAS9. (A) Twenty-nine mutants are visible among 33 mutant plants: yellow plants smaller than WT. (B) From left to right, a WT plant, a heterozygous C- > T plant, and a homozygous C- > T plant. The heterozygous and homozygous plants have a pale-yellow phenotype, as expected, and the homozygous plant is shorter than the heterozygous plant and the WT
