Abstract
The sequences around translation initiation codons (from -20 to +13) were compared among 271 cDNA clones obtained from peach fruit. Following features were found: 1) three or more consecutive bases containing single kind or repetitive sequences which is made up of six or more bases are frequently existed in 5' untranslated regions. 2) from -4 to -1, "A" appears frequently than others, namely 43% at -1 and "AA" at -2 to -1 is 25%. 3) "G" appears 72% frequency at +4, "C" at +5 is 55%. Accordingly, most frequently found amino acid residue at second is Alanine with a 40% frequency. 4) in frame stop codon is found in 49 clones (18%) and out of frame in 109 clones (40%). Collectively, many different features are found in the sequences before and after the initiation codons, which may be correlated with establishment of translation initiation point or with efficiency of translation.
