Ecological Interactions, Environmental Gradients, and Gene Flow in Local Adaptation
anti-herbivore defense environmental gradients evolution gene flow herbivore–pollinator interaction sphenology
2023/12/7
Despite long-standing interest in local adaptation of plants to their biotic and abiotic environment, existing theory, and many case studies, little work to date has addressed within-species evolution...
Study reveals surprising amount of gene flow among butterfly species（图）
surprising amount gene flow among butterfly species
2019/11/15
Scientists know that shared parts of DNA create color patterns in some passion vine butterflies. The patterns help the butterflies ward off predators.Now a new study in Science provides evidence that ...
Genetic diversity within and gene flow between three draught horse breeds using genealogical information
genetic drift inbreeding Silesian Noriker Noriker Czech-Moravian Belgian horse
2016/11/11
Three draught horse breeds are maintained in the Czech Republic: the Silesian Noriker (SN), the Noriker (N), and the Czech-Moravian Belgian (CMB). Because the SN and CMB populations are currently clos...
A Method for Detecting Population Genetic Structure in Diverse, High Gene-Flow Species
Diverse High Gene-Flow Species
2015/12/11
Detecting small amounts of genetic subdivision across geographic space remains a persistent challenge. Often a failure to
detect genetic structure is mistaken for evidence of panmixia, when more powe...
QUANTIFYING GENE FLOW FROM OILSEED RAPE TO ITS WILD RELATIVES USING REMOTE SENSING (LANDSAT TM)
Gene gene flow sports population crop wild swap genes genetically modified

Gene flow is defined as the movement of genes between populations and is a naturally occurring phenomenon
among sexually compatible individuals. Crops have exchanged genes with their wild and weedy ...
摘要群体遗传结构上的差异是遗传多样性的一种重要体现，对群体遗传结构的研究已有较久的历史，而其中的基因流研究近些年来越来越受到重视。它对群体遗传学、进化生物学、保护生物学、生态学有着极其重要的作用。虽然传统的群体遗传学能估测基因流大小，但它的精确性还有很大局限性。随着生物技术的进步，对基因流的研究逐渐向分子水平过渡，应用蛋白质电泳技术、分子标记技术(RAPD、RFLP、VNTR、ISSR、DNA测序...
降低转基因植物外源基因扩散的分子策略 Molecular Strategies for Decreasing the Gene Flow of Transgenic Plants
转基因植物 基因扩散 分子策略
2008/1/8
摘要
转基因植物可以通过花粉或种子将外源基因转移到其他植物，从而对生态环境造成潜在的危害。如何降低外源基因的扩散已引起了人们的极大关注。目前降低外源基因扩散的方法主要有叶绿体转化、花粉不育、种子不育、闭花受精、无融合生殖、暂时性控制及转基因缓和等。主要对各种方法的原理和优缺点及目前的使用情况进行综述。Abstract: Transgenic plants can transfer foreign...
Strong genetic clines and geographical variation in gene flow in the rocky intertidal barnacle Balanus glandula
California Current cline, dispersal marine invertebrate
2015/12/16
A long-standing issue in marine biology is identifying spatial scales at which populations
of sessile adults are connected by planktonic offspring. We examined the genetic continuity of
the acorn ba...
