[作者:Ito, S; Song, YH; Josephson-Day, AR; Miller, RJ; Breton, G; Olmstead, RG; Imaizumi, T,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3582-3587 , 文章类型: Article,,卷期:2012年109-9]
- Many plants monitor day-length changes throughout the year and use the information to precisely regulate the timing of seasonal flowering for maximum reproductive success. In Arabidopsis thaliana, transcriptional regulat...
- Quantifying the hurricane risk to offshore wind turbines
[作者:Rose, S; Jaramillo, P; Small, MJ; Grossmann, I; Apt, J,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3247-3252 , 文章类型: Article,,卷期:2012年109-9]
- The U.S. Department of Energy has estimated that if the United States is to generate 20% of its electricity from wind, over 50 GW will be required from shallow offshore turbines. Hurricanes are a potential risk to these ...
- At 6-9 months, human infants know the meanings of many common nouns
[作者:Bergelson, E; Swingley, D,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3253-3258 , 文章类型: Article,,卷期:2012年109-9]
- It is widely accepted that infants begin learning their native language not by learning words, but by discovering features of the speech signal: consonants, vowels, and combinations of these sounds. Learning to understan...
- Metabolomic analysis reveals that carnitines are key regulatory metabolites in phase transition of the locusts
[作者:Wu, R; Wu, ZM; Wang, XH; Yang, PC; Yu, D; Zhao, CX; Xu, GW; Kang, L,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3259-3263 , 文章类型: Article,,卷期:2012年109-9]
- Phenotypic plasticity occurs prevalently and plays a vital role in adaptive evolution. However, the underlying molecular mechanisms responsible for the expression of alternate phenotypes remain unknown. Here, a density-d...
- Predictive microfluidic control of regulatory ligand trajectories in individual pluripotent cells
[作者:Moledina, F; Clarke, G; Oskooei, A; Onishi, K; Gunther, A; Zandstra, PW,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3264-3269 , 文章类型: Article,,卷期:2012年109-9]
- Local (cell-level) signaling environments, regulated by autocrine and paracrine signaling, and modulated by cell organization, are hypothesized to be fundamental stem cell fate control mechanisms used during development....
- Active maintenance of nuclear actin by importin 9 supports transcription
[作者:Dopie, J; Skarp, KP; Rajakyla, EK; Tanhuanpaa, K; Vartiainen, MK,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:E544-E552 , 文章类型: Article,,卷期:2012年109-9]
- Besides its essential and well established role as a component of the cytoskeleton, actin is also present in the cell nucleus, where it has been linked to many processes that control gene expression. For example, nuclear...
- Trafficking of gap junction channels at a vertebrate electrical synapse in vivo
[作者:Flores, CE; Nannapaneni, S; Davidson, KGV; Yasumura, T; Bennett, MVL; Rash, JE; Pereda, AE,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:E573-E582 , 文章类型: Article,,卷期:2012年109-9]
- Trafficking and turnover of transmitter receptors required to maintain and modify the strength of chemical synapses have been characterized extensively. In contrast, little is known regarding trafficking of gap junction ...
- Conversion of the chill susceptible fruit fly larva (Drosophila melanogaster) to a freeze tolerant organism
[作者:Kostal, V; Simek, P; Zahradnickova, H; Cimlova, J; Stetina, T,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:3270-3274 , 文章类型: Article,,卷期:2012年109-9]
- Among vertebrates, only a few species of amphibians and reptiles tolerate the formation of ice crystals in their body fluids. Freeze tolerance is much more widespread in invertebrates, especially in overwintering insects...
