Corn sugar transport gene Zmstp24 and application thereof

Abstract

The application discloses a corn sugar transport gene ZmSTP24 and application thereof. The nucleotide sequence of the corn ZmSTP24 gene is shown as SEQ ID NO. 1, and the amino acid sequence coded by the gene is shown as SEQ ID NO. 2. Through CRISPR / Cas9 technology, the corn ZmSTP24 gene is edited and its function is researched. Compared with a transgenic receptor, the ZmSTP24 transgenic strain has a significantly reduced grain sucrose content, starch content and grain size. It is shown that the ZmSTP24 gene cloned in the application positively regulates the accumulation of grain sugar and other carbohydrates, and influences corn filling and grain size.
