- Movement and equipositioning of plasmids by ParA filament disassembly
[作者:Ringgaard, S; van Zon, J; Howard, M; Gerdes, K,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19369-19374 , 文章类型: Article,,卷期:2009年106-46]
- Bacterial plasmids encode partitioning (par) loci that confer stable plasmid inheritance. We showed previously that, in the presence of ParB and parC encoded by the par2 locus of plasmid pB171, ParA formed cytoskeletal-l...
- Soft X-ray tomography of phenotypic switching and the cellular response to antifungal peptoids in Candida albicans
[作者:Uchida, M; McDermott, G; Wetzler, M; Le Gros, MA; Myllys, M; Knoechel, C; Barron, AE; Larabell, CA,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19375-19380 , 文章类型: Article,,卷期:2009年106-46]
- The opportunistic pathogen Candida albicans can undergo phenotypic switching between a benign, unicellular phenotype and an invasive, multicellular form that causes candidiasis. Increasingly, strains of Candida are becom...
- Phylogenetic structure in tropical hummingbird communities
[作者:Graham, CH; Parra, JL; Rahbek, C; McGuire, JA,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19673-19678 , 文章类型: Article,,卷期:2009年106-46]
- How biotic interactions, current and historical environment, and biogeographic barriers determine community structure is a fundamental question in ecology and evolution, especially in diverse tropical regions. To evaluat...
- Telomere shortening relaxes X chromosome inactivation and forces global transcriptome alterations
[作者:Schoeftner, S; Blanco, R; de Silanes, IL; Munoz, P; Gomez-Lopez, G; Flores, JM; Blasco, MA,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19387-19392 , 文章类型: Article,,卷期:2009年106-46]
- Telomeres are heterochromatic structures at chromosome ends essential for chromosomal stability. Telomere shortening and the accumulation of dysfunctional telomeres are associated with organismal aging. Using telomerase-...
- Sodium shortage as a constraint on the carbon cycle in an inland tropical rainforest
[作者:Kaspari, M; Yanoviak, SP; Dudley, R; Yuan, M; Clay, NA,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19405-19409 , 文章类型: Article,,卷期:2009年106-46]
- Sodium (Na) is uncommon in plants but essential to the metabolism of plant consumers, both decomposers and herbivores. One consequence, previously unexplored, is that as Na supplies decrease (e. g., from coastal to inlan...
- Ecology and the ratchet of events: Climate variability, niche dimensions, and species distributions
[作者:Jackson, ST; Betancourt, JL; Booth, RK; Gray, ST,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19685-19692 , 文章类型: Article,,卷期:2009年106-46]
- Climate change in the coming centuries will be characterized by interannual, decadal, and multidecadal fluctuations superimposed on anthropogenic trends. Predicting ecological and biogeographic responses to these changes...
- How blood-derived odor influences mate-choice decisions by a mosquito-eating predator
[作者:Cross, FR; Jackson, RR; Pollard, SD,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19416-19419 , 文章类型: Article,,卷期:2009年106-46]
- Evarcha culicivora (Araneae, Salticidae) feeds indirectly on vertebrate blood by choosing, as preferred prey, bloodcarrying female mosquitoes. Mutual mate-choice behavior is also pronounced in this species. Here we show ...
- A mechanism for functional segregation of mitochondrial and cytosolic genetic codes
[作者:Espanol, Y; Thut, D; Schneider, A; de Pouplana, LR,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19420-19425 , 文章类型: Article,,卷期:2009年106-46]
- The coexistence of multiple gene translation machineries is a feature of eukaryotic cells and a result of the endosymbiotic events that gave rise to mitochondria, plastids, and other organelles. The conditions required f...
- Age-related hearing loss in C57BL/6J mice is mediated by Bak-dependent mitochondrial apoptosis
[作者:Someya, S; Xu, JZ; Kondo, K; Ding, DL; Salvi, RJ; Yamasoba, T; Rabinovitch, PS; Weindruch, R; Leeuwenburgh, C; Tanokura, M; Prolla, TA,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:19432-19437 , 文章类型: Article,,卷期:2009年106-46]
- Age-related hearing loss (AHL), known as presbycusis, is a universal feature of mammalian aging and is the most common sensory disorder in the elderly population. The molecular mechanisms underlying AHL are unknown, and ...
