Abstract

See full text

Applications of a ZmROA1 protein or substance regulating the content or activity of the ZmROA1 protein are provided. The ZmROA1 protein can be specified as follows: A1), A2) or A3): A1, the amino acid sequence is the amino acid sequence shown in SEQ ID NO: 3; A2, the protein, which is obtained by replacing and/or deleting and/or adding the amino acid sequence shown in SEQ ID NO: 3 through amino acid residues, is more than 80% identity to A1) and relates to plant root angle; A3, the fusion protein which is obtained by linking N-end or/and C-end of A1) or A2) to protein tags. ZmROA1 protein and its related biological materials can be used to regulate plant density tolerance and/or root angle, and the cultivation of new density-tolerant maize varieties, which helps improve maize harvest index for high and stable yield.
