Methods and compositions for increasing yield of short stature plants through manipulation of gibberellin metabolism

摘要

The present disclosure provides compositions and methods for altering gibberellin (GA) content in corn or other cereal plants. Also provided are methods and compositions for altering expression of genes involved in gibberellin biosynthesis through inhibition, mutagenesis, and / or editing of certain subtypes of the GA20 or GA3 oxidase gene. Modified plant cells with inhibitory elements and mutations that reduce the expression or activity of plant or GA oxidase genes include reduced gibberellin levels and improved features such as reduced plant height and increased doping resistance, but without off-type Additionally provided.
