ABSTRACT
Summary The palea and lemma (hull) are grass‐specific organs, determine grain size quality. In the study, AH 2 encodes a MYB domain protein, functions in development of hull grain. Mutation produces smaller grains alters quality including decreased amylose content gel consistency, increased protein content. Meantime, part lost outer silicified cells, induces transformation rough epidermis to inner smooth body was reduced ah2 mutant. We confirmed function by complementation, CRISPR ‐Cas9, cytological molecular tests. Additionally, , as repressor, repress transcription downstream genes. Our results revealed that plays an important role determination development, identity, size.
