The Structure of Some Cytoplasmic Components of Plant Cells in Relation to the Biochemical Properties of Isolated Particles
1. Electron micrographs of thin sections of material fixed with buffered osmium tetroxide have been used for comparison of the fine structure of isolated cytoplasmic particles from silver beet petioles and roots of germinating wheat with that of the cytoplasm of the intact cells. 2. Mitochondria of wheat roots have an external double membrane and poorly oriented internal double membranes. As co...
متن کاملReaction of Wheat Yield to Soil Physical and Chemical Characteristics in Arak Fields
In order to evaluate the impact of physical and chemical properties of soil on Bekras kind wheat yield in the city of Arak, a completely randomized block experimental plan has been implemented with three replications in the1390 crop year. Treatments include the overall condition and qualifications of wheat field 's soil in 18 wheat farms, which were randomly selected. Traits in this experiment ...
متن کاملNuclear Dna and Cytoplasmic Dna from Tissues of Higher Plants
Young wheat roots were labeled with (32)P-inorganic phosphate. Following the labeling period, roots were homogenized in a sucrose medium and fractionated into nuclei, cytoplasmic particles (including proplastids and mitochondria), and a soluble fraction containing most of the microsomes. DNA prepared from the particles had a higher buoyant density than that from the nuclei and showed a marked l...
متن کاملThe Development in Vitro of Particles from Cytoplasm
A system is described in which microscopically visible particles develop from cytoplasmic proteins incubated in vitro. The conditions required for the development of particles are those usually associated with enzymic reactions. The particles are believed to develop as a result of enzyme action on cytoplasmic proteins in the presence of compounds having certain specific chemical configurations....
متن کاملIn vitro capacity and in vivo antioxidant potency of sedimental extract of Tinospora cordifolia in streptozotocin induced type 2 diabetes
Objective: The role of herbs against the free radicals have been put forth recently in combating many diseases. The aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of Tinospora cordifolia (SETc). Materials and Methods: SETcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydr...
