Abstract
Camellia oleifera is an essential oil woody plant. The development of the camellia industry can relieve the a China’s pressure of importing edible oil. However, there are few studies on the codon usage bias (CUB) in C. oleifera genes. In this study, the codon usage patterns were analyzed by 35,178 reconstructed genes from the C. oleifera transcriptome. The mean GC and GC3 content of all transcripts was 51.14% and 55.43% respectively. A total of 18 optimal codons were identified, 15 of them ending with A or U. Which indicated the use of A/U codons was high frequency. Furthermore, the natural selection and mutational pressure, both influenced CUB in C. oleifera, however the natural selection was the most deciding factor. The nucleotide excretion of C. oleifera genome is rich. C. oleifera prefers A/U ending codons, and nature selection is one of the most important factors affecting CUB. This study will lay a theoretical foundation for the research of molecular evolution and genetic engineering in C. oleifera.
