We propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article
Tools and mathematical methods offered for usage represent essentially new base for forecasting of discrete evolutionary processes. Authors represent complete system of models and methods of temporary ranks’ with memory forecasting
There was determined that the heat resistance of fruit and decorate plants depends not only on their morpho-biological peculiarities but on the specific of temperature stressor revealing in corresponding years. There were selected three types of influence of high air temperature on plants on plants during summer period and three components of heat resistance respectively. There were cited possible mechanisms of plant adaptation to overheat. There were cited diagnostic criteria of their heat resistance
Value of new linear sorts allocated by the method of analytical selection from sort Stepnaya 7 in increase of adaptability of winter soft wheat is discussed. The new linear sorts: Line 15, AMMA, Line 21, Line 11, Line 26, Line 29, Line 36, Line 37 revealed combination of stability to brown and yellow rusts. Productive varieties with high quality of grain: Magnificent, Line 12, Line 38 have shown stability to a brown rust and poorly affected by other mushroom diseases
The results of the research of stability of the model of neutrophilomonocytegenesis are shown in the article. With the criterion of Routh-Hurwitz it's calculated that the system of the differential equations of cells growing is asymptotically steady. Threshold values of parameters of model at which the system becomes unstable are defined
These studies are devoted to determining the characteristics of changes in some physiological and biochemical parameters of sweet cherry plants that arise under the influence of the main damaging factor of the spring period - frost and associated with the resistance of the plant organism to the action of stressor. The studies were carried out in 2012 and adjacent 2018-2019 in the fruiting plantations of cherries of the Kuban zone located on horticultural soils: leached chernozem and alluvial meadow. We studied sweet cherry varieties of different resistance to frost. Samples for analysis were selected according to the background of naturally prevailing positive air temperatures. The plant material was frozen in the Binder climate chamber KB 53 for 4 hours at a temperature of 2.5 ± 0.2 ° C. According to the results of the experiment, sweet cherry plants that differ in early flowering are more susceptible to the temperature stressor in the spring in comparison with late flowering plant organisms. Meanwhile, the resistance of plants to frost depends not so much on the date of differentiation of the generative buds, but on the efficiency of the physiological and biochemical activation mechanisms under the influence of an unfavorable synthesis factor in the flowers of indolylacetic acid, which is responsible for the efficiency of the onset of fruit formation, and ultimately a more complete implementation potential productivity. An important indicator of the stability of a plant organism is the degree of change in the content of this phytohormone

The differential stability of mRNA is an important
mechanism for posttranscriptional regulation of gene
expression in eukaryotes. Messenger RNA stability is
controlled by specific genes and growth conditions.
The review examines the theoretical possibility of
mRNA stabilization in vivo as a consequence of
replacing carbon atoms (C) or phosphorus (P),
composed of nucleic acid on the silicon (Si) atom.
During isolation of poly-(A)+mRNA from plant
tissues by the two-cycle affinity chromatography on
poly-(U)-Sepharose, regular changes in poly-
(A)++mRNA yield were observed. The changes
varied both with the plant genotype and growth
conditions. Celite treatment of heated and unheated
total RNA preparations from developing corn kernels
and from green and etiolated wheat seedlings.
Messenger RNA that differed in the length of poly-
(A)-sequences was used for hybridization. It is
evident that a reduction of poly-(A)-length causes
alterations in spatial structure of mRNA, and
associated proteins and cations Mg++ become
accessible to celite absorption. Heating promotes
melting of secondary structure, already initiated, and
increases the efficiency of mRNA stabilization by
celite. Interpreting the facts interact celite with mRNA
in vitro and stabilization of mRNA in vivo by
cycloheximide with a modern point of view can be considered with the position research of the
phenomenon of RNA interference
