PBF factor is one of the protein factors regulating the expression of wheat endosperm specific gene, and plays an important role in regulating the expression of wheat seed storage protein genes. In this study, the CDS sequence of TaPBF3-5D was obtained from wheat germplasm ZY96-3 by RT-PCR, and its bioinformatics and gene expression were analyzed. The results showed that the CDS sequence of TaPBF3-5D had a total of 909 bp, encoding 302 amino acids. The encoded protein is a non-transmembrane unstable hydrophilic protein without signal peptide, and it contains 36 phosphoric acid sites. It is predicted to be located in the nucleus. Phylogenetic tree and multiple sequence alignment showed that TaPBF3-5D was more closely related to the PBF from common wheat. Quantitative fluorescence analysis showed that TaPBF3-5D gene was expressed in roots, stems, leaves, and seeds, with the highest expression in seeds, followed by leaves and stems, and the lowest expression in roots. It indicated TaPBF3-5D gene regulating the grain development of wheat through participating in the regulation of wheat grain storage protein gene expression.
