The Wild Rice Whole Genome Frame Map is Completed by KIB Scientists
In August 2010, the research team headed by GAO Li-Zhi in Kunming Institute of Botany, Chinese Academy of Sciences completed the de novo sequencing and assembling of wild rice (Oryza rufipogon) genome and has acquired the frame map covering the whole genome of wild rice. This is the first wild ri... 查看详细>>
Cytotoxic Triterpene Dilactones from the Stems of Kadsura ananosma
    Six new triterpene dilactones with a rare rearranged pentacyclic skeleton, longipedlactones K-P (1-6), and seven known analogues (7-13) were isolated from the stems of Kadsura ananosma. Compound I was found to possess a unique peroxide bridge between C-1 and C-9 in rings A and B. The structur... 查看详细>>
Melodinines A-G, Monoterpenoid Indole Alkaloids from Melodinus he...
   Nineteen monoterpenoid indole alkaloids including seven new ones, melodinines A-G (1-7), were isolated from Melodinus henryi. The structures of the new compounds were elucidated using spectroscopic methods, and the Structure of compound 4 was confirmed by single-crystal X-ray diffraction ana... 查看详细>>
Extended expression of B-class MADS-box genes in the paleoherb As...
  Asarum caudigerum (Aristolochiaceae) is a paleoherb species that is important for research in origin and evolution of angiosperm flowers due to its basal position in the angiosperm phylogeny. In this study, a subtracted floral cDNA library from floral buds of A. caudigerum was constructed and... 查看详细>>
Vibralactones D-F from Cultures of the Basidiomycete Boreostereum...
  Three new metabolites, vibralactones D-F (1-3) were isolated from cultures of the basidiomycete Boreostereum vibrans. The relative configuration of I was established on the basis of X-ray diffraction analysis, while the absolute configurations of 1-3 were assigned using a modified Mosher's me... 查看详细>>
Asymmetric hybridization in Rhododendron agastum: a hybrid taxon ...
  Rhododendron (Ericaceae) is a large woody genus in which hybridization is thought to play an important role in evolution and speciation, particularly in the Sino-Himalaya region where many interfertile species often occur sympatrically. Rhododendron agastum, a putative hybrid species, occurs ... 查看详细>>
