摘要： The present disclosure provides compositions and methods for altering auxin accumulation in corn or other cereal plants. Methods and compositions are also provided for altering the expression of genes related to auxin efflux through editing of a Brachytic2 (br2) gene to introduce an antisense sequence or segment or a deletion or premature stop codon into the gene. Modified plant cells and plants having a dominant or semi-dominant allele reducing the expression or activity of a br2 gene product are further provided comprising improved characteristics, such as reduced plant height and increased lodging resistance, but without off-types in the plant.
