- Primordial organisms of the putative RNA world would have required polymerase ribozymes able to replicate RNA. Known ribozymes with polymerase activity best approximating that needed for RNA replication contain at their ...
- Transcriptome Complexity in a Genome-Reduced Bacterium
[作者:Guell, M; van Noort, V; Yus, E; Chen, WH; Leigh-Bell, J; Michalodimitrakis, K; Yamada, T; Arumugam, M; Doerks, T; Kuhner, S; Rode, M; Suyama, M; Schmidt, S; Gavin, AC; Bork, P; Serrano, L,期刊:Science, 页码:1268-1271 , 文章类型: Article,,卷期:2009年326-5957]
- To study basic principles of transcriptome organization in bacteria, we analyzed one of the smallest self-replicating organisms, Mycoplasma pneumoniae. We combined strand-specific tiling arrays, complemented by transcrip...
- Impact of Genome Reduction on Bacterial Metabolism and Its Regulation
[作者:Yus, E; Maier, T; Michalodimitrakis, K; van Noort, V; Yamada, T; Chen, WH; Wodke, JAH; Guell, M; Martinez, S; Bourgeois, R; Kuhner, S; Raineri, E; Letunic, I; Kalinina, OV; Rode, M; Herrmann, R; Gutierrez-Gallego, R; Russell, RB; Gavin, AC; Bork, P; Serra,期刊:Science, 页码:1263-1268 , 文章类型: Article,,卷期:2009年326-5957]
- To understand basic principles of bacterial metabolism organization and regulation, but also the impact of genome size, we systematically studied one of the smallest bacteria, Mycoplasma pneumoniae. A manually curated me...
- Extensive, Recent Intron Gains in Daphnia Populations
[作者:Li, WL; Tucker, AE; Sung, W; Thomas, WK; Lynch, M,期刊:Science, 页码:1260-1262 , 文章类型: Article,,卷期:2009年326-5957]
- Rates and mechanisms of intron gain and loss have traditionally been inferred from alignments of highly conserved genes sampled from phylogenetically distant taxa. We report a population-genomic approach that detected 24...
- Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly
[作者:Mann, ME; Zhang, ZH; Rutherford, S; Bradley, RS; Hughes, MK; Shindell, D; Ammann, C; Faluvegi, G; Ni, FB,期刊:Science, 页码:1256-1260 , 文章类型: Article,,卷期:2009年326-5957]
- Global temperatures are known to have varied over the past 1500 years, but the spatial patterns have remained poorly defined. We used a global climate proxy network to reconstruct surface temperature patterns over this i...
