A geranium (Pelargonium graveolens) chloroplast translational elongation factor EF-Tu (tufA) cDNA was isolated. The geranium tufA cDNA is 1,584 bp long with 20 bp of 5′ untranslated region (UTR) and 139 bp of 3′ UTR. It encodes 474 amino acids including a putative chloroplast transit peptide of 65 amino acids. The deduced polypeptides of the geranium tufA cDNA contains four GTP binding sequences in its N-terminal region and two chloroplast EF-Tu signature regions in the C-terminal region. The predicted molecular weight of the mature geranium chloroplast EF-Tu protein was about 45,000 and its amino acid sequence identity with the chloroplast EF-Tu proteins of tobacco, pea, Arabidopsis, rice, and soybean ranges from 85% to 91%. The geranium tufA appears to exist as a single copy gene like Arabidopsis and rice, whereas other known dicot plants have more than one copy in their nuclear genomes.
