Summary: | Shoot branching is fundamentally important in determining soybean yield. Here, through genome-wide association study, we identify one predominant association locus on chromosome 18 that confers soybean branch number in the natural population. Further analyses determine that
Dt2
is the corresponding gene and the natural variations in
Dt2
result in significant differential transcriptional levels between the two major haplotypes. Functional characterization reveals that Dt2 interacts with GmAgl22 and GmSoc1a to physically bind to the promoters of
GmAp1a
and
GmAp1d
and to activate their transcription. Population genetic investigation show that the genetic differentiation of
Dt2
display significant geographic structure. Our study provides a predominant gene for soybean branch number and may facilitate the breeding of high-yield soybean varieties.
Shoot branching is critical in determining soybean yield. Here, the authors report natural variation of
Dt2
in controlling soybean branching number and the interaction of Dt2 with GmAgl22 and GmSoc1a to activate transcription of
GmAp1a
and
GmAp1d
