  • Structural Basis of Immune Evasion at the Site of CD4 Attachment on HIV-1 gp120
    [作者:Chen, L; Kwon, YD; Zhou, TQ; Wu, XL; O'Dell, S; Cavacini, L; Hessell, AJ; Pancera, M; Tang, M; Xu, L; Yang, ZY; Zhang, MY; Arthos, J; Burton, DR; Dimitrov, DS; Nabel, GJ; Posner, MR; Sodroski, J; Wyatt, R; Mascola, JR; Kwong, PD,期刊:Science, 页码:1123-1127 , 文章类型: Article,,卷期:2009年326-5956]
  • The site on HIV-1 gp120 that binds to the CD4 receptor is vulnerable to antibodies. However, most antibodies that interact with this site cannot neutralize HIV-1. To understand the basis of this resistance, we determined...
  • Symbiotic Nitrogen Fixation in the Fungus Gardens of Leaf-Cutter Ants
    [作者:Pinto-Tomas, AA; Anderson, MA; Suen, G; Stevenson, DM; Chu, FST; Cleland, WW; Weimer, PJ; Currie, CR,期刊:Science, 页码:1120-1123 , 文章类型: Article,,卷期:2009年326-5956]
  • Bacteria-mediated acquisition of atmospheric N-2 serves as a critical source of nitrogen in terrestrial ecosystems. Here we reveal that symbiotic nitrogen fixation facilitates the cultivation of specialized fungal crops ...
  • A First-Generation Haplotype Map of Maize
    [作者:Gore, MA; Chia, JM; Elshire, RJ; Sun, Q; Ersoz, ES; Hurwitz, BL; Peiffer, JA; McMullen, MD; Grills, GS; Ross-Ibarra, J; Ware, DH; Buckler, ES,期刊:Science, 页码:1115-1117 , 文章类型: Article,,卷期:2009年326-5956]
  • Maize is an important crop species of high genetic diversity. We identified and genotyped several million sequence polymorphisms among 27 diverse maize inbred lines and discovered that the genome was characterized by hig...
  • The B73 Maize Genome: Complexity, Diversity, and Dynamics
    [作者:Schnable, PS; Ware, D; Fulton, RS; Stein, JC; Wei, FS; Pasternak, S; Liang, CZ; Zhang, JW; Fulton, L; Graves, TA; Minx, P; Reily, AD; Courtney, L; Kruchowski, SS; Tomlinson, C; Strong, C; Delehaunty, K; Fronick, C; Courtney, B; Rock, SM; Belter, E; Du, FY,期刊:Science, 页码:1112-1115 , 文章类型: Article,,卷期:2009年326-5956]
  • We report an improved draft nucleotide sequence of the 2.3-gigabase genome of maize, an important crop plant and model for biological research. Over 32,000 genes were predicted, of which 99.8% were placed on reference ch...
