This invention relates to the field of
genetic engineering breeding technology, and discloses genes related to maize flowering period regulation, their expression products, haplotypes, and applications. The genes... ZmTL1, ZmHSP70-10, ZmMHF1 The
nucleotide sequences are shown in SEQ ID NO.1, SEQ ID NO.3, and SEQ ID NO.5, and the
amino acid sequences of the proteins they
encode are shown in SEQ ID NO.2, SEQ ID NO.4, and SEQ ID NO.6. This invention also provides haplotypes of these genes. ZmZP1 The six haplotypes of a
gene ZmHSP70-10 Two haplotypes of the
gene ZmMHF1 Five haplotypes of the
gene were identified. These genes, their expression products, and their haplotypes can be used to identify different tasseling,
pollen shedding, and silking stages suitable for summer
sowing in the Huang-Huai-Hai region. They also provide
core gene resources for breeding new maize varieties resistant to extreme climates, significantly improving the precision of
flowering time regulation and breeding efficiency, and have significant application value. The application methods can be extended to breeding practices for other
flowering time-related regulatory genes.
