متن کاملVariation in floral sex allocation in Polygonatum odoratum (Liliaceae).
BACKGROUND AND AIMS It is well known that resource allocation to male and female functions can be highly variable in hermaphroditic plants. The purpose of this study was to investigate variations in sexual investment at different levels (flower, plant and population) in Polygonatum odoratum, a plant with sequentially opening flowers. METHODS Pollen and ovule production in base, middle and top...
متن کاملIsolation and characterization of a bacteriophage polysaccharide.
A high molecular weight heteropolysaccharide, composed of glucose, glucuronic acid, N-acetylglucosamine, and mannose in an approximate molar ratio of 1:2:2:5, respectively, was isolated from phage K-2 and from the soluble fraction of phage-infected Aerobacter aerogenes lysates. Treatment of pure phage with 8 M urea at 4 degrees quantitatively solubilizes the bound polysaccharide and capsular po...
متن کاملIsolation and characterization of the lipopolysaccharides from Bradyrhizobium japonicum.
The lipopolysaccharide (LPS) of Bradyrhizobium japonicum 61A123 was isolated and partially characterized. Phenol-water extraction of strain 61A123 yielded LPS exclusively in the phenol phase. The water phase contained low-molecular-weight glucans and extracellular or capsular polysaccharides. The LPSs from B. japonicum 61A76, 61A135, and 61A101C were also extracted exclusively into the phenol p...
متن کاملPurification and Partial Structural Characterization of a Complement Fixating Polysaccharide from Rhizomes of Ligusticum chuanxiong.
Rhizome of Ligusticum chuanxiong is an effective medical plant, which has been extensively applied for centuries in migraine and cardiovascular diseases treatment in China. Polysaccharides from this plant have been shown to have interesting bioactivities, but previous studies have only been performed on the neutral polysaccharides. In this study, LCP-I-I, a pectic polysaccharide fraction, was o...
