Anatomical structure of the common in forests and meadows Georgian subalpine zone plant - Aconitum nasutum Fisch. ex Reichenb underground aerial vegetative organs, rich diterpene alkaloids, was studied. A set diagnostic features has been established using accepted microtechnical methods. The conductive system axial organs A. nasutum, root, twig leaf stalk, a separated collateral structure. Casp...

Asymmetric cell divisions occur widely during many developmental processes in plants. In most angiosperms, the first zygotic cell division is asymmetric resulting in two daughter cells of unequal size and with distinct fates. However, the critical molecular mechanisms regulating this division remain unknown. Previously we showed that treatment of tobacco zygotes with beta-glucosyl Yariv (βGlcY)...

The paper deals with phytoplankton quantitative indicators and dominant complex structure, dimensional morphological characteristics of detritus particles in the ponds Hostomel urban settlement. Water quality has been assessed according to characteristics. abundance made up 2648.0–113675.0 thousand cells  dm–3, it was mainly formed by Cyanobacteria. biomass varied within 3.72–16.53 g m–3, whic...
