This invention belongs to the field of
biotechnology applications and discloses a
gene containing a
kinesin domain that is associated with the height trait of the first fruiting
branch of cotton. GhFFBPH And its applications. This invention provides the cDNA sequence (SEQ ID NO.1) and
genome sequence (SEQ ID NO.2) of this
gene in tetraploid upland cotton TM-1, and the
gene... GhFFBPH The gene contains a non-synonymous SNP located at 353 bp in the
coding region, where the base changes from A to T, and the corresponding
amino acid changes from Gln to Leu. The gene provided in this invention was obtained from cotton variety resequencing and
genome-wide association analysis, and is significantly associated with the height trait of the first fruiting
branch in cotton. Two haplotypes of this gene are used to distinguish the height
phenotype of the first fruiting
branch: the AA
haplotype corresponds to the tall
phenotype, and the TT
haplotype corresponds to the short
phenotype. This invention... GhFFBPH Genes have significant research value and application prospects in improving the height of the first fruiting branch of cotton and in breeding new varieties of cotton with high first fruiting branch height.
