Genomic Characteristics and Codon Preference Analysis of Schefflera octophylla(Lour.)Harms Chloroplasts
摘要
Abstract
To study the genetic structure and function,genetic codon preference,influencing factors and optimal codon of Schefflera octophylla,the Schefflera octophylla(Lour.)Harms was used as research material.The full sequence of the chloroplast genome was sequenced and assembled.The results showed that the chloroplast genome of S.octophylla was consist of a large single copy region,a small single copy region and 2 reverse repeat regions,with a total length of 156 532 bp,and 123 functional genes were obtained including 8 ribosomal rRNA genes,29 tRNA genes and 86 protein coding genes.A total of 84 SSR loci were detected.The preference analysis of codons showed that the optimal codons of S.octophylla chloroplast genomic codons tended to end in A/U bases,which indicated natural selection was main factor of preference analysis of codons.Phylogenetic analysis showed that S.actophylla had closely related to Kalopanax septemlobus.Above results provided scientific basis for the study and application of chloroplast genome of S.octophylla.关键词
