食肉目猫科物种的系统发育学研究概述被引量:3
2012年
猫科动物(Felidae)是食肉目中肉食性最强的一科,其中许多成员是人们最熟悉、最引人注目的动物,也是各地的顶级食肉动物。目前37个现存猫科物种中有36个已经被列为濒危和稀有对象。食肉目猫科物种的进化历史是一个快速辐射和较近时期发生的物种形成事件,使得猫科物种之间系统发育关系的重建非常困难,一直处于广泛争论的状态。构建可靠的猫科系统发育关系,具有重要的进化理论意义和保护生物学价值。文章对猫科物种的系统发育学研究进展,包括来自于形态学特征、细胞学和分子生物学方面的证据做简要概述,并提出目前研究中存在的问题。以期对今后猫科物种的系统发育方面的进一步研究工作具有指导意义,并为该类群的生物多样性资源保护提供科学依据。

Summary of phylogeny in subfamily Colobinae(Primate:Cercopithecidae)被引量:2
2013年
The phylogeny of the colobine monkeys has a complex evolutionary history,evolving several distinct radiations and owned a wide range of forest and woodland habits in tropical Africa and in southern and eastern Asia.Understanding the true evolutionary history of the colobine monkeys becomes an important field and has received special attention.In this article,we review phylogeny of Colobinae based on previous fossil,cytological,morphological and molecular evidence and indicate the phylogenetic controversies.This review is expected to guide the future research of Colobinae phylogeny,and also provide theoretic evidence for the conservation of these highly endangered and unique primates.

哺乳动物犁鼻器信息素感知及犁鼻器系统特异基因的分子进化研究进展被引量:5
2010年
生物对外界环境中化学物质信号的识别和感知对其生存有着极其重要的意义.大多数哺乳动物具有两条嗅觉通路,主要嗅觉系统(MOS)用来感受普通嗅觉信号,而犁鼻器系统(VNS)则从异常灵敏的程度来识别小范围内特异性的化学感应信号-信息素(pheromone).信息素是一类在同种内个体间传递的物质,可引发群体内与个体交流和生殖相关的一系列生理和行为变化.本文综述了对哺乳动物犁鼻器信息素感知及犁鼻器系统特异(VNS-specific)基因的分子进化研究进展,这些基因包括信息素受体家族V1R和V2R以及离子通道TRPC2,为进一步深入研究哺乳动物信息素感知的分子机制奠定基础。

Molecular evolution of stress-response gene Leptin in high-altitude Chinese snub-nosed monkeys (Rhinopithecus genus)被引量:3
2010年
Chinese snub-nosed monkeys (genus Rhinopithecus, subfamily Colobinae), including R. bieti, R. brelichi and R. roxellana, are well-known as the non-human primates with the highest known altitudinal distribution. They represent an interesting model organism of adaptation to the extreme environmental stresses. However, no study at the molecular level has yet been reported for the high-altitude adaptation in Chinese snub-nosed monkeys. Leptin, as an adipocyte-derived hormone, is believed to play an important role in energy homeostasis in adaptation to high altitude environments. In the present study, we sequenced and compared leptin sequences of the Chinese snub-nosed monkeys (R. bieti and R. roxellana) with their lowland close relative R. avunculus and other Colobines. Unexpectedly, no amino acid changes were observed in the 7 Colobinae species examined, including the 2 Chinese snub-nosed monkeys, indicating no difference in the evolutionary pattern of the Leptin gene between high-altitude monkeys and their lowland counterparts. In contrast to a previous finding of adaptive evolution of Leptin gene in plateau pikas, our study suggests that this gene may not have an important role in high-altitude adaptation of Chinese snub-nosed monkeys. Other nuclear genes associated with energy metabolism, or mitochondrial genes, are most likely to be involved the molecular mechanism underlying adaptation of these monkeys to cold and hypoxia associated with the highland environment.

Natural selection and adaptive evolution of leptin被引量:5
2013年
Leptin is an adiposity-secreted hormone that is pivotal in regulating feeding behavior,energy metabolism and body mass.The study of leptin has been of crucial importance for public health and pharmaceutical intervention given its role in obesity.Generally,leptin is highly conserved due to its functional importance.However,episodes of rapid sequence evolution and positive selection have been observed in some mammalian species,indicating that the leptin functions in these animals may have undergone adaptive modification to their environments.In this article,we review the adaptive evolution of leptin and its potential functional consequences.This review is expected to guide future research of molecular evolution and functional assays of this gene,and also to provide a theoretical foundation for the use of leptin in therapeutic applications.

Duplication and functional diversification of pancreatic ribonuclease (RNASE1) gene被引量:3
2010年
Adaptation is one of the most fundamental issues in the studies of organismal evolution. Pancreatic ribonuclease is a very impor- tant digestive enzyme and secreted by the pancreas. Numerous studies have suggested that RNASE1 gene duplication is closely related to the functional adaptation of the digestive system in the intestinal fermentation herbivores. RNASE1 gene thus becomes one of the most important candidate genetic markers to study the molecular mechanism of adaptation of organisms to the feeding habit. Interestingly, RNASE1 gene duplication has also been found in some non-intestinal fermentation mammals, suggesting that RNASE1 gene may have produced novel tissue specificity or functions in these species. In this review, RNASE1 gene and its im- plications in adaptive evolution, especially in association with the feeding habit of organisms, are summarized.
