摘      要：Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight(TGW)in wheat(Triticum aestivum L.).However,no mutations have been identified within the gene to test this *** effects of TaSus1 on grain number per spike(GNS)also are largely *** previous genome-wide association study identified TaSus-A1 as a candidate gene controlling fertile spikelet number per spike(FSN).In the present study,we generated two independent mutants for the three TaSus1 homoeologs by CRISPR/Cas9-mediated genome *** triple mutants displayed lower FSN,GNS,grain number per spikelet(GNST),and TGW than wild-type *** 306 hexaploid wheat accessions,two single-nucleotide polymorphisms in TaSus-A1 contributed differently to *** of the two alleles into a wheat genetic background confirmed their *** alleles differed in geographical distribution among the accessions.
