We used large samples of expressed sequence tags to characterize the patterns of codon usage bias (CUB) in seven different Citrus species and to analyze their evolutionary effect on selection and base composition. We found that A- and T-ending codons are predominant in Citrus species. Next. we identified 21 codons for 18 different amino acids that were considered preferred codons in a... https://www.oxfordofbluebell.com/product-category/fantasy-art/
