To develop functional markers related to wheat plant type, we identified members of the wheat OTUBs family in this study, cloned a potential plant type-related gene, TaOTUB1, and analysed the expression pattern of the gene. The result showed that TaOTUB1 gene was widely expressed in various tissues of wheat and had the highest expression abundance among the 33 members of the wheat OTUBs family. The natural variation of the TaOTUB1 gene was analyzed using 748 wheat genome natural variation data, and it was found that two haplotypes, HapⅠ and HapⅡ, mainly existed in the TaOTUB1-A promoter region. The development of a dCAPS molecular marker based on SNPs at the -761 bp locus enabled the effective identification of HapⅠ and HapⅡ in 313 wheat varieties. Linkage analysis revealed that HapⅠ is an excellent haplotype for plant type improvement and yield increase. Evolutionary analysis revealed that HapⅠ is the dominant haplotype in domestic and foreign-cultivated wheat. These results can be helpful for plant type improvement and molecular marker-assisted selection breeding in wheat.
