The DNA fragment contains an open reading frame of 1 344 nucleotides and encodes 447 amino acids. Seguence analysis of DNA and deduced polypeptide demonstrated that it encoded for a pea elongation factor 1-alpha (EF-1α). The functional domains of EF-1α is well conserved and EF-1α can be a good candidate for studying molecular evolution.展开更多
