Structural Insights into Plant Viruses Revealed by Small-Angle X-ray Scattering and Atomic Force Microscopy.

The structural study of plant viruses is of great importance to reduce the damage caused by these agricultural pathogens and to support their biotechnological applications. Nowadays, X-ray crystallography, NMR spectroscopy and cryo-electron microscopy are well accepted methods to obtain the 3D protein structure with the best resolution. However, for large and complex supramolecular structures such as plant viruses, especially flexible filamentous ones, there are a number of technical limitations to resolving their native structure in solution.

Features of the Formation of Communities of Microorganisms Adapting to the Existing Conditions in Different Types of Agrophytocenoses.

The article is devoted to studying the features of the formation of communities of microorganisms, adapting to the conditions of existence in various types of agrophytocenoses. The study was carried out on model weed plant species, the most common in agrophytocenoses of the Belgorod region. Two nutrient media were prepared for microbiological examination: nutrient agar (BPA - the number of mesophilic aerobic and facultative anaerobic microorganisms) and ENDO - an elective medium for CB ( bacteria).

Hyperspectral imaging for small-scale analysis of Hordeum vulgare L. leaves under the benzo[a]pyrene effect.

Hyperspectral imaging is a newly developed approach to estimate the current state of the plants and to develop the methods of soil and plant ecological state improvement under the effect of different sources. The study was devoted to the novel approach of hyperspectral imaging application in the case of persistent organic pollutants (POP) uptake by plants. Hordeum vulgare L.

Plant Invasion Research in Russia: Basic Projects and Scientific Fields.

This paper represents a review of comprehensive research into invasion biology done by Russian scholars for four decades. Invasion biology is a relatively new field of research focused on the study of alien plants, their behavior in new habitats and risks they pose to indigenous species. It is shown that over 40 years, single finds of alien plant species have transformed into a check-list of invasive species in Russia.
