cord-310298-26x2p9wc	Tao, Pan	Analysis of synonymous codon usage in classical swine fever virus	2008-10-29		.txt	text/plain	3416	184	56	Using the complete genome sequences of 35 classical swine fever viruses (CSFV) representing all three genotypes and all three kinds of virulence, we analyzed synonymous codon usage and the relative dinucleotide abundance in CSFV. The general correlation between base composition and codon usage bias suggests that mutational pressure rather than natural selection is the main factor that determines the codon usage bias in CSFV. As shown in Table 4 , the first axis value in COA of each selected genome, which contains most of the variation in synonymous codon usage bias between these genomes, is closely correlated with the GC composition at the first, second, and third codon position. Mean values of 35 CSFVs relative dinucleotide ratios ± S.D Table 3 Summary of correlation analysis between the first two axes in COA and sixteen dinucleotides in the selected viruses , indicating that the overall extent of codon usage bias in CSFV genomes is low.	./cache/cord-310298-26x2p9wc.txt	./txt/cord-310298-26x2p9wc.txt
