The present invention discloses isolated polynucleotides and polypeptides, recombinant DNA constructs and CRISPR-Cas constructs for regulating the heading stage or flowering stage of plants, and also includes CMP1 genes containing these recombinant DNA constructs or modifications or their regulation Compositions of elements (eg, plants or seeds), and methods of utilizing these recombinant DNA constructs and CRISPR-Cas constructs. The recombinant DNA construct comprises a CMP1 gene and a functional promoter in a plant operably linked thereto, and the CRISPR-Cas construct targets the CMP1 gene or its regulatory elements, wherein the CMP1 gene encodes a flowering time regulating polypeptide. |
