Analyses of Codon Usage Patterns and Codon Usage Bias in Peach (<i>Prunus persica</i>)

To further study the characteristics of peach codon usage, this analyzed usage biases and patterns genome, based on statistical calculations related GC content, effective number codons (ENC) relative synonymous (RSCU) from 26 873 coding sequences. The results showed that there were obvious in peach, 4 out 61 (UCA, ACA, GCA GAA) defined as optimal codons, all which end with Adenine at third position. Further analyses frequency among other 9 species Rosaceae found genus similar. These also suggested was a positive correlation between copy tRNA genes occurrence corresponding amino acids (and specific codons) genome. revealed Peach provide an important reference for relevant studies mechanism genetic engineering.
