- As one of the most abundant polysaccharides on Earth, xylan will provide more than a third of the sugars for lignocellulosic biofuel production when using grass or hardwood feedstocks. Xylan is characterized by a linear ...
- Synergy of multiple partners, including freeloaders, increases host fitness in a multispecies mutualism
[作者:Palmer, TM; Doak, DF; Stanton, ML; Bronstein, JL; Kiers, ET; Young, TP; Goheen, JR; Pringle, RM,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17234-17239 , 文章类型: Article,,卷期:2010年107-40]
- Understanding cooperation is a central challenge in biology, because natural selection should favor "free-loaders" that reap benefits without reciprocating. For interspecific cooperation (mutualism), most approaches to t...
- Ancient class of translocated oomycete effectors targets the host nucleus
[作者:Schornack, S; van Damme, M; Bozkurt, TO; Cano, LM; Smoker, M; Thines, M; Gaulin, E; Kamoun, S; Huitema, E,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17421-17426 , 文章类型: Article,,卷期:2010年107-40]
- Pathogens use specialized secretion systems and targeting signals to translocate effector proteins inside host cells, a process that is essential for promoting disease and parasitism. However, the amino acid sequences th...
- Structural insights into the pH-controlled targeting of plant cell-wall invertase by a specific inhibitor protein
[作者:Hothorn, M; Van den Ende, W; Lammens, W; Rybin, V; Scheffzek, K,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17427-17432 , 文章类型: Article,,卷期:2010年107-40]
- Invertases are highly regulated enzymes with essential functions in carbohydrate partitioning, sugar signaling, and plant development. Here we present the 2.6 angstrom crystal structure of Arabidopsis cell-wall invertase...
- Autotrophic ammonia oxidation by soil thaumarchaea

- Nitrification plays a central role in the global nitrogen cycle and is responsible for significant losses of nitrogen fertilizer, atmospheric pollution by the greenhouse gas nitrous oxide, and nitrate pollution of ground...
- Effects of past, present, and future ocean carbon dioxide concentrations on the growth and survival of larval shellfish
[作者:Talmage, SC; Gobler, CJ,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17246-17251 , 文章类型: Article,,卷期:2010年107-40]
- The combustion of fossil fuels has enriched levels of CO2 in the world's oceans and decreased ocean pH. Although the continuation of these processes may alter the growth, survival, and diversity of marine organisms that ...
- Conservation, development, and function of a cement gland-like structure in the fish Astyanax mexicanus
[作者:Pottin, K; Hyacinthe, C; Retaux, S,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17256-17261 , 文章类型: Article,,卷期:2010年107-40]
- The larvae of the fish Astyanax mexicanus transiently develop a flat and adhesive structure on the top of their heads that we have called "the casquette" (cas, meaning "hat"). We hypothesized that the cas may be a teleos...
- Evidence for the prepattern/cooption model of vertebrate jaw evolution
[作者:Cerny, R; Cattell, M; Sauka-Spengler, T; Bronner-Fraser, M; Yu, FQ; Medeiros, DM,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:17262-17267 , 文章类型: Article,,卷期:2010年107-40]
- The appearance of jaws was a turning point in vertebrate evolution because it allowed primitive vertebrates to capture and process large, motile prey. The vertebrate jaw consists of separate dorsal and ventral skeletal e...
- Polymorphic genetic control of tumor invasion in a mouse model of pancreatic neuroendocrine carcinogenesis
