Protecting diversity on coral reefs:DNA may hold the key
Protecting diversity coral reefs DNA
2016/5/6
Coral reefs are widely known for their stunning array of color, shape and forms of life, making them a model for extreme biodiversity. Hidden within the multitude of reef inhabitants, but no less...
中国将建海洋生物DNA数据库
中国 海洋生物 DNA数据库
2014/8/19
记者2014年8月18日获悉：科技部科技基础性工作专项部署了“我国近海海洋生物DNA条形码资源库构建”项目。该项目由中国科学院海洋研究所承担，计划用5年时间建成海洋生物DNA条形码数据库，形成一套海洋生物鉴定识别的标准体系。据介绍，研究人员将首先选择我国近海原核生物、植物、浮游动物、大型底栖无脊椎动物及鱼类等类群中常见的、关键的、有代表性的、与人们生活密切相关的重要海洋生物物种，进行DNA条形码序...
中国将开展近海海洋生物DNA条形码数据库构建
中国 近海海洋生物 DNA条形码数据库
2014/8/18
中国海洋生物资源丰富，具备极高的物种多样性，当前海洋经济发展和海洋科学研究亟需对我国海洋生物多样性资源进行充分认知，其中对物种的准确识别更是基础性的工作。目前我国专业的海洋生物分类学研究团队规模有限，依靠传统经验为主的海洋生物形态鉴定方法具有较大局限性，无法满足日益增长的海洋科研、海洋经济和管理的需求。因此，DNA条形码作为新兴的物种快速准确鉴定的方法，正发挥越来越重要的作用；DNA条形码资源库作...

Algal–bacterial competition for phosphorus from dissolved DNA, ATP, and orthophosphate in a mesocosm experiment
Algal– bacterial competition phosphorus dissolved DNA ATP orthophosphate a mesocosm experiment
2014/4/22
We measured the turnover of phosphorus (P) from radioactive-labeled dissolved deoxyribonucleic acid (dDNA), adenosine triphosphate (ATP), and orthophosphate, and the partitioning of P from these sourc...
Early diagenesis and trophic role of extracellular DNA in different benthic ecosystems
Early diagenesis extracellular DNA different benthic ecosystems
2014/4/22
To provide new insights into the early diagenesis of extracellular deoxyribonucleic acid (DNA) and its relevance in trophodynamic processes, we collected sediment samples from a variety of coastal and...
Viral infection plays a key role in extracellular DNA dynamics in marine anoxic systems
Viral infection plays a key role extracellular DNA dynamics marine anoxic systems
2014/4/23
To investigate the role of viruses in extracellular DNA production through cell lysis, we selected two systems where viruses are expected to be the main component controlling prokaryote dynamics. Thes...
Associations among ribosomal (r)DNA intergenic spacer length, growth rate, and C : N : P stoichiometry in the genus Daphnia
Associations growth rate
2014/5/16
The growth rate hypothesis (GRH) proposes that variation in organismal C : N : P ratios is associated
with growth rate due to differential allocation to P-rich ribosomal RNA to support growth. A furt...
Quantification, base composition, and fate of extracellular DNA in marine sediments
Quantification, base composition fate of extracellular DNA marine sediments
2014/5/27
The discovery of high concentrations of DNA in marine sediments unaccounted for by living biomass suggests the presence of a large fraction of extracellular DNA, which might play an important role in ...
The influence of food quality (P:C ratio) on RNA:DNA ratio and somatic growth rate of Daphnia
The influence of food quality P:C ratio RNA:DNA ratio somatic growth rate of Daphnia
2014/5/26
Growth experiments with juvenile Daphnia galeata were performed to investigate how fast their RNA:DNA ratio responds to changes in food quality, the relationship between RNA:DNA ratio and somatic grow...
