Abstract: Based on the EST sequence encoded the 14-3-3,gene-specific primer was designed and used to obtain the full-length cDNA of a novel 14-3-3 gene from Pyrus pyrifolia Nakai cv. Huobali in Yunnan province with?the method of rapid amplification of cDNA ends (RACE). This novel gene was named as Pp14-3-3. Pp14-3-3 is?1 107 bp in length with an ORF of 786 bp,a 5'-untranslated region (UTR) of 84 bp,and a 3'-UTR of 237 bp,and?the ORF encodes a predicted polypeptide of 261 amino acids. The Pp14-3-3 shares higher homology with the known?14-3-3 proteins,and possesses the basic stucture of 14-3-3 proteins. A phylogenetic analysis of the relationship of?the newly identified Pp14-3-3 with some known 14-3-3s from other species grouped the Pp14-3-3 into the class of?non-ε 14-3-3s. Pp14-3-3 is abundantly expressed in pericarps of Huobali regardless received sunlight or not,and also expression in the young leaves. Isolation and expression analysis of Pp14-3-3 in this study laid the groundwork for?further studying on function of Pp14-3-3 .
