In the present study, fauna of small mammals of the
Taman Peninsula is analyzed. It is shown that the
complex of rodents and insectivores inhabiting the
study area differs considerably from the adjacent
continental areas and is an isolate. Structure of its
fauna and population resembles that of the steppe parts
of Crimea and, at the same time, North-West NearCaspian
areas. Analyses of variation of the D-loop
regions of mtDNA in yellow-bellied mouse Sylvaemus
witherbyi, as well as certain peculiarities of the species
diversity, show the priority of faunal and genetic
connections of the Taman Peninsula’s mammal fauna
with the North-West Near-Caspian one
In the presented study, we have performed genotyping

It is stainable for high winter hardiness, drought resistance and increased resistance to fungal diseases, tolerant to phylloxera. The top of the young shoot is green without pubescence. Young shoots are green, without pubescence. The flower is hermaphroditic. The cluster is large, conical, branching, winged, of medium density. The berry is medium-sized, short elliptical, green-yellow. Peel is thin, strong. The pulp is juicy, with a varietal flavor. The sugar content is high. Rudiments of seeds are soft. The variety is intended for fresh consumption and kishmish production. The table high-yielding seedless variety Vasiliy Nosulchak in terms of winter hardiness, resistance to diseases and pests significantly exceeds all Eurasian varieties of table and kishmish designation. Can be used as a table grapevine for fresh consumption on site and for export, as well as for the production of high-quality dried products. As a winter-hardy variety, it is very promising for cultivation in covered viticulture zones, where table varieties require shelter for the winter. It is of great interest for selection work in breeding frost-resistant, diseases and pests of seedless varieties. To determine the influence of different ecological conditions on the growth, development, quantity and quality of the crop, the variety must be tested on all continents in different ecological and geographical areas of cultivation - in the grapes producing countries of America, Eurasia, Australia, Africa
Professional apple gardening is bound to particular
risks, of which is essential losses of a harvest because
of diseases. An apple scab, the caused Venturia
inaequalis (Cooke) G. Winter, brings the greatest
loss. The main approach in monitoring of a scab of an
apple-tree is creation of grades, steady against
pathogen. In the present work we have carried out
phytopathology testing of generations of the seedlings
received from the free pollination of six forms of a
crab of Malus orientalis from a collection MOS VIR
(Maykop) characterized by a relative resistance to the
apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both
of natural population of a scab, and of strains of
pathogen of various cultivars and geographical origin.
When carrying out padding infection increase in force
of an infectious background that can be bound to
selection of the plants of biotypes of a fungus that are
most adapted for genotypes was noted. It is
recommended for precise elimination of unstable
plants at selection at early stages of an ontogenesis to
carry out more than one serial infection during the
season. By results of the phytopathological testing,
we highlighted three Malus orientalis forms from the
six studied No. 17982, 17985 and 3080 the most
perspective stability genes for an introgressiya in a
cultural gene pool of an apple tree
The distribution and variability of features of the
endemic of flora Eastern Caucasus Centaurea
daghestanica (Lipsky) Czer. were given in this article.
Eleven locations of the species are detected and three
of them are new ones. C. daghestanica grows in the
lower and middle mountain belts from 400 to 1250 m
above sea level. In the lower belt, the species is found
on clayey areas of the solonchak valley of Kar-Kar and
the limestone slopes adjoining the valley, on average
on shale screes and stony slopes. Three populations of
the C. daghestanica we studied. Species composition
on the investigated sites was determined, and a
geobotanical description is carried out. Project
coverage of C. daghestanica in the studied populations
varies within 2–5%. By generative individuals of
different ages were represented mainly populations.
One generative shoot from 30 individuals in each
population was taken to reveal the variability of the
generative shoot structure, on which 13 traits were
taken into account. The degree of variability of the
morphological features of C. daghestanica shoot is
different, the influence of the altitude level on them is
not the same. The annual shoot of C. daghestanica has
an average of 3-5 branches of the first order. Branches
of all levels are located at the bottom of the shoot
Rice fields all over the world are one of the places of invasion of adventive weed species. They can reduce the yield of the rice crop by 20-30%. The phytomonitoring studies in the rice systems of the Krasnodar region in 2017 have discovered a new species of Ammannia coccinea Rottb. (Lythraceae) among the weed vegetation of the grain crops. The article gives a botanical description of the species; its biological and ecological features and ways of its distribution are discussed. Ammannia coccinea is an annual plant, light-loving and hygrophilous. The country of origin is North America. This is one of the most malicious weeds in California and the United States in general. In Asian and European countries, the plant is brought with rice seeds. Currently, in many rice-growing regions of the world, the species A. coccinea tends to spread and increase the severity of infestation. The species was registered in the Krasnodar region in the rice fields of the Abinskiy, Kalininskiy, Krasnoarmeiskiy and Slavyanskiy regions. The number of plants of A. coccinea does not exceed one plant per 10 m2, with the exception of three locations of invasion, where the density is up to 5-7 pcs/m2 and the plants occupy an area about 0.5 hectares. Considering the fact that in rich soils the height of the plant reaches 1 m, with the ramification of the stem, the plants go to the first tier. They successfully compete with rice plants, suppressing their growth and development. This can adversely affect crop yield. The article discusses the reasons for the appearance of A. coccinea in the rice fields of the Krasnodar region
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
Industrial horticulture assumes the most effective use of
the potential of varieties. One of the key factors
determining the yield of garden plantings is the
effectiveness of pollination. To obtain the maximum
yield, it is necessary to ensure maximum pollination
during the flowering period. For this reason, much
attention has been paid to the selection of pollinators.
Crab-apple forms are promising for use as pollinators, so
this work was aimed at identifying the most common
alleles of the self-incompatibility gene in the crab-forms
using the molecular genetic method of analysis. The
object of the study was 29 apple-tree creams and 3 elite
selection forms. They carried out the molecular genetic
identification of alleles S2 and S10, which are among
the most common apple trees in the world gene pool.
Allele S2 was identified in 16 samples (14 forms and 2
elite selection forms), while S10 allele in one
sample (elite form 12/2-20 (24-28)). Data on the allelic
composition of the S gene in the samples studied are of
value for the formation of a genetic passport on the
compatibility of the studied samples of apple with
modern industrial varieties
