Analysis of Chloroplast Genome Sequence and Codon Preference of Pleione
摘要
Abstract
To clarify the usage pattern of codons in the chloroplast genome of Pleione,16 species of Pleione were used as study materials,and Codon W 1.4.2 and online software CUSP were used to obtain GC,RSCU,ENC and other relevant parameters of codons in Pleione,and neutral mapping,PR2-plot and optimal codon analysis were also carried out.The results showed that the contents of codons GC1,GC2,GC3 and GCall were similar in 16 species,and each species showed the following pattern:GC1＞GC2＞GC3,which indicated that the GC contents in the same species of Pleione were not uniformly distributed in different positions of the codons,and the codons preferred to end in A/U;the ENC values were all more than 35,which indicated that the codon preferences of Pleione were weak.It is evident that the formation of codon preferences in the chloroplast genomes of Pleione was mainly influenced by natural selection.The relative sequence usage(RSCU)and ENC values were used to identify the 10-22 optimal codons,most of which ended in A/U.关键词
