60 YEARS IN THE RANKS: FEATURES OF MOLECULAR BIOLOGY OF BEZOSTAYA 1 WINTER WHEAT VARIETY
DescriptionThis review is devoted to the 60 anniversary of the winter wheat variety (Triticum aestivum L.) Bezostaya 1 – a masterpiece of world selection. This variety played a great role in increasing total grain yields in the Kuban Region. It also was an important gene source for Russian and world breeding. This variety has initiated and was for many years a party to research molecular biological mechanisms of wheat frost resistance formation. The article summarizes data about the peculiarities of functioning of protein-synthesizing system it sprouts (coleoptilies) under the influence of hardening temperature (4oC): translational activity in vitro, poliribosomts, degree of polyadenilation and stability of total mRNA and specific mRNA translational elongation factor α subunit 1 (eEF-1 α). The in vitro (ommp) system, which adequately characterizes the relative mRNA stability in vivo was used for these measurements. The effects of cooling and light on mRNA stability were shown to be cultivar-specific. The hardiness of winter wheat has a positive relationship with the amount of RNA and DNA, and a negative correlation with the amount of magnesium cations in mature grain that can serve as a simple marker of frost resistance. The main feature of the variety Bezostaya 1 is high content of magnesium ions (Mg++) in RNA molecules and relatively low variation of Mg++-depending molecularphysiological responses for different environmental conditions. The knowledge gained in the study of variety of Bezostaya 1 contributes to the understanding of molecular biological processes that underlie the selection and determining its future success

ISSR ANALYSIS OF PINUS SYLVESTRIS TREES APPURTENANT TO DIFFERENT SELECTION CATEGORIES
DescriptionThe genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268

LEAF MORPHOMETRY OF KUBAN WILD-GROWING GRAPE LIANA
DescriptionLeaf morphometry of Kuban wild-growing grape liana has not been studied yet and there is no evidence of straight subspecies representatives location of Vitis vinifera silvestris Gmel. on the Kuban land. Though there have been suppositions about it in science since long ago [5]. With morphometric taxonomy appearance there was necessity of exact focusing on modern state of genotypic grape variety and biological leaf polymorphism for link identification silvestris – silvesatis - sativa

Description
Based on the information stored in the system of database management, biodiversity indices with special accent on measures of species richness are comparatively studied for Carabid beetles in various areas of the East Caucasus. Biodiversity indices are shown to be dependent on sampling or collecting techniques, sample size, geographic localization and its area

ABIOTIC PECULIARITIES OF SMALL RIVERS OF THE STEPPE ZONE OF THE KRASNODAR REGION
DescriptionSteppe rivers (Eja, Beysug, Chelbas et al.) occupy a vast Azov-Kuban plain, whose total length reaches 4800 km and catchment area of the entire hydrological network of up to 24 000 km. Dams and silting increase flooding of agricultural land and many rivers severely degraded with a reduction of its water content and its quality. Landscapes of the steppe zone occupy a middle reaches of the largest rivers - Beysug River, Chelbas, Eja and differ of transaccumulative character and accompanied by numerous beams and small slope that prone to weak erosion. The valleys of the steppe rivers are characterized by high and gentle slopes and floodplains of river slightly wavy and their deep areas are swamped. As a parent rocks it is dominated by loess clay and clay. Features of soil cover are determined by topography. Black soils were formed on the plain, eroded and meadow-black soils are on the slopes, and meadow-bog soils - in areas with stagnant water. The climate is characterized by moderate winter and hot summers with insufficient moistened soil and low air humidity. The vegetation of the river systems of the steppe zone is divided into marsh, meadow, meadow-steppe vegetations and vegetations of saltmarshes. The ichthyofauna of small rivers is very scanty that is determined by the hydrological regime. Plowing of lands along the water bodies, the development of wind and water erosion is typical for steppe rivers; therefore siltation and overgrowing of rivers are widespread

AGRO-BOTANICAL ICONOGRAPHY TURBANOFORMIS FRUIT FORMS SPICIES OF CUCIRBITACEAE
DescriptionPlants images in painting, mosaics, scientific illustration, herbals and books or agro-botanical iconography is a valuable resource of the information about the history of the spread of various phenotypes, such as turbanoformis form of pumpkin in the past century in different regions of the world

Description
The article considers the agro-botanical characteristics of pumpkin annual plants – lagenaria ( Lagenaria siceraria (Molina) Standl.) have been consider in article. The task of the analytical study went in search of communication between anatomic-morphological characteristics of plant and use this in the images, the iconography of the cultural traditions of different nation

Description
The article discusses agro-botanical illustration of hand fans painting as an independent resource of visual information on the history of culture of introduction, distribution, species diversity and plant breeding. We have reviewed the history of the fan and the causes of widespread of fans and the respective painting plants. The article shows the different trends in the filing of a visual image in the fan art: from accurate, detailed drawing of the image, until smooth, blurred contours, made in the "boneless" or "acyclic" technique. On the example of pumpkins, lagenaria, soybeans, corn, flowers, namely asters and peonies we have shown various aspects of breeding and agronomic work for several centuries. The article uses the method of visual analysis as a tool for collection and analysis of data on breeding and introduction of a number of crops on the example of specific crops, particularly soybeans. The analysis includes a description of morphotypes, area of origin, distribution, physiology, individual characteristics, and insects found in the ecological niche. It is noted that visual analysis can be successfully applied in the study of varietal diversity of a number of flower crops: asters, peonies, chrysanthemums, and some fruits and vegetables

Description
The article considers turban cucumber forms, we have also described the origin of this characteristic, briefly overviewed turban forms in species of the family of Cucurbitaceae. We have given the agro-botanical iconography of this trait in pumpkin cultures for cucumis. In Europe, China and America turbanoformis cucumber forms are used as a vegetable, there are some varieties. It is shown that turbanoformis forms are found in the fruit of the cucumber with hermaphrodite flower, polunina ovaries, short or shareplace the melon, and also in forms with the ongoing evolutionary process
