Three haplotypes were identified in Chinese wheat Bay 65-1942 R form core collections, and a haplotype association analysis showed that was significantly correlated with the production of larger kernels and higher kernel weights in modern Chinese cultivars. The haplotype effect resulted from a difference in expression levels between genotypes, with resulting in lower expression levels. This favourable haplotype was found having been positively selected during wheat breeding over the last century. Furthermore, we demonstrated that TaDA1\A physically interacts with TaGW2\B. The additive effects of and on kernel weight were confirmed not only by the phenotypic enhancement arising from the simultaneous down\regulation of and expression, but also by the combinational haplotype effects estimated from multi\environment field data from 348 wheat cultivars. A comparative proteome analysis of developing transgenic and wild\type grains indicated that TaDA1 and TaGW2 are involved in partially overlapping but relatively independent protein regulatory networks. Thus, we have identified an important gene controlling kernel size in whole wheat and established its discussion with MADH9 additional genes regulating kernel pounds, which could possess helpful applications in whole wheat mating. L., AABBDD) can be a significant staple crop in the globe. With developing global inhabitants and raising demand for whole wheat, wheat yields must be further improved. Grain weight and size are major components of wheat yield and are therefore key targets for the further improvement of this crop (Li and Yang, 2017; Mohler (Qin (Zhang (Ma (Ma (Hanif (Sajjad and (Hou carries a G\to\A mutation in allele dramatically increases the seed and organ size of plants because the mutant DA1R358K protein negatively impacts the function of DA1 and DAR1 (Li or homologs also improved their seed weights and Bay 65-1942 R form organ sizes, thereby increasing the overall grain yield and biomass (Wang mutant (also caused an increase in seed size, indicating that can be studied relatively independently of in regulating seed size (Dong and in both restricted seed growth, similar to the phenotype change in rice (Xia in wheat using a bioinformatics approach and mapped the homoeologs on chromosomes 2A, 2B, and 2D. Transgenic analysis showed that this overexpression of in wheat causes a decline in kernel size and weight, while the down\regulation of using RNA interference (RNAi) had the opposite effect, indicating that has a conserved function in the unfavorable regulation of kernel size. Our haplotype association analysis also exhibited that, in modern Chinese cultivars, the favourable haplotype of was significantly associated with higher kernel weights. Moreover, we found that TaDA1\A physically interacted with TaGW2\B and verified their additive effects not only through the enhanced kernel size phenotype generated by the simultaneous down\regulation of and in wheat, but also using a combinational analysis of and haplotypes in the association population. Our findings provide evidence that is an important gene controlling kernel size in wheat, and it can be potentially applied in combination with other produce\related genes in whole wheat high\yield breeding.
