The evolution of female sex pheromones

引用

Current Zoology 2013年第4期59卷 569-578页

作者： Ally R. HARARI Hadass STEINITZ Department of Entomology The Volcani Center Bet Dagan Israel

The role of female sex pheromones in natural selection, particularly as a means for species recognition to avoid the generation of hybrid offspring with low fitness, has been widely explored and is generally accepted by scholars. However, the significance of sex pheromones in shaping mate choice （sexual selection） and in competition over breeding resources （social se- lection） has been largely ignored. The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute, while the role of sex pheromones in competition over breeding resources （other than mates） has not yet been considered. As a result of natural selection, variation in sex pheromones among females is expected to be low, and males are not expected to choose their mates among phero- mone-releasing conspecific females. Sexual selection, on the other hand, should drive the increase in pheromone variance among females, and males are expected to choose females based on this variation. Moreover, social selection resulting from more general social interactions, for example competition among females for breeding sites and food, should also promote variance among female sex pheromones. Here, we review the cttrrent evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait. We suggest that the three selection types are not mutually exclusive but rather act together to promote different fimess components in diverse ecological situations

Synonymous codon usage pattern in model legume Medicago truncatula

Journal of Integrative Agriculture 2018年第9期17卷 2074-2081页

作者： SONG Hui LIU Jing CHEN Tao NAN Zhi-biao State Key Laboratory of Grassland Agro-ecosystems College of Pastoral Agriculture Science and Technology Lanzhou University Grassland Agri-husbandry Research Center Qingdao Agricultural University

Synonymous codon usage pattern presumably reflects gene expression optimization as a result of molecular evolution. Though much attention has been paid to various model organisms ranging from prokaryotes to eukaryotes, codon usage has yet been extensively investigated for model legume Medicago truncatula. In present study, 39 531 available coding sequences （CDSs） from M. truncatula were examined for codon usage bias （CUB）. Based on analyses including neutrality plots, effective number of codons plots, and correlations between optimal codons frequency and codon adaptation index, we conclude that natural selection is a major driving force in M. truncatula CUB. We have identified 30 optimal codons encoding 18 amino acids based on relative synonymous codon usage. These optimal codons characteristically end with A or T, except for AGG and TTG encoding arginine and leucine respectively. Optimal codon usage is positively correlated with the GC content at three nucleotide positions of codons and the GC content of CDSs. The abundance of expressed sequence tag is a proxy for gene expression intensity in the legume, but has no relatedness with either CDS length or GC content. Collectively, we unravel the synonymous codon usage pattern in M. truncatula, which may serve as the valuable information on genetic engineering of the model legume and forage crop.

Genome-scale analysis of demographic history and adaptive selection

引用

Protein & Cell 2014年第2期5卷 99-112页

作者： Qi Wu Pingping Zheng Yibu Hu Fuwen Wei Key Lab of Animal Ecology and Conservation Biology Institute of Zoology Chinese Academy of Sciences

One of the main topics in population genetics is identification of adaptive selection among populations. For this purpose, population history should be correctly inferred to evaluate the effect of random drift and exclude it in selection identification. With the rapid progress in genomics in the past decade, vast genomescale variations are available for population genetic analysis, which however requires more sophisticated models to infer species' demographic history and robust methods to detect local adaptation. Here we aim to review what have been achieved in the fields of demographic modeling and selection detection. We summarize their rationales, implementations, and some classical applications. We also propose that some widely-used methods can be improved in both theoretical and practical aspects in near future.
