Codon Usage Pattern and its Influencing Factors for Mitochondrial CO Genes Among Different Subfamilies of Cerambycidae.

This study examined nucleotide composition and codon usage of mitochondrial CO (cytochrome oxidase) genes from four subfamilies of Cerambycidae. Nucleotide composition analysis of the CO genes revealed an AT-rich pattern in the four subfamilies of Cerambycidae. Furthermore, by analyzing the correlation between the overall nucleotide composition of CO genes and the nucleotide composition of the 3rd codon, we found that mutation pressure and natural selection were the key factors affected the CUB.

The complete chloroplast genome of W.P. Fang (Ericaceae), a endemic plant from the Southern Dabie Mountains of China.

W.P. Fang 1983 (Ericaceae) is woody plant naturally distributed in the southwest of Anhui, China.

Out of the Qinghai-Tibetan Plateau and rapid radiation across Eurasia for section (Amaryllidaceae).

The disjunctive distribution (Europe-Caucasus-Asia) and species diversification across Eurasia for the genus sect. has fascinating attractions for researchers aiming to understanding the development and history of modern Eurasia flora. However, no any studies have been carried out to address the evolutionary history of this section.

Phylogeny of Chinese Species in Section and Adaptive Evolution of (Amaryllidaceae, Allioideae) Species Revealed by the Chloroplast Complete Genome.

The genus (Amaryllidaceae, Allioideae) is one of the largest monocotyledonous genera and it includes many economically important crops that are cultivated for consumption or medicinal uses. Recent advances in molecular phylogenetics have revolutionized our understanding of taxonomy and evolution. However, the phylogenetic relationships in some sections (such as the section ) and the genetic bases of adaptative evolution, remain poorly understood.
