Nuclear sheets in the egg of a fern, Dryopteris filix-mas.
In the maturing egg of Dryopteris filix-mas the nucleus is shown to produce sheet-like extensions into the cytoplasm, resembling those described in certain somatic cells of animals. In these sheets the distance between the 2 inner membranes of the envelope is regularly of the order of 45-50 nm, and the nuclear material is organized into a monolayer of electron-opaque aggregates 35-40 nm in diam...

متن کاملEffects of Chloroform Extract of Dryopteris crassirhizoma on the Ultramicroscopic Structures of Meloidogyne incognita
In our early experiments, the chloroform extract of D. crassirhizoma was demonstrated to contain the highest concentrations of total phloroglucinols among several extract fractions and possessed the most effective nematicidal activity. This study aimed to ascertain the ultrastructural changes in M. incognita after treatment with a D. crassirhizoma chloroform extract at 1 mg·mL⁻¹ for 24 h. It wa...
متن کاملaCGH-MAS: Analysis of aCGH by means of Multiagent System
There are currently different techniques, such as CGH arrays, to study genetic variations in patients. CGH arrays analyze gains and losses in different regions in the chromosome. Regions with gains or losses in pathologies are important for selecting relevant genes or CNVs (copy-number variations) associated with the variations detected within chromosomes. Information corresponding to mutations...
متن کاملWhat Is the Impact of Impatiens parviflora on Diversity and Composition of Herbal Layer Communities of Temperate Forests?
The aim was to estimate the impacts of invasive Impatiens parviflora on forests' herbal layer communities. A replicated Before-After-Control-Impact field experiment and comparisons with adjacent uninvaded plots were used. The alien's impact on species richness was tested using hierarchical generalized mixed effect models with Poisson error structure. Impact on species composition was tested usi...
