ALLELIC VARIANTS AND EXPRESSION CANDIDATE GENES FOR ABDOMINAL FATMASS IN CHICKENS
DescriptionThe expression of nine candidate genes for QTL abdominal fat weight and relative abdominal fat content was investigated by real-time polymerase chain reaction (PCR) in the liver, adipose tissue, colon, muscle, pituitary gland and brain of broilers. The high mobility group AT hook1 (HMG1A) gene was up-regulated in liver with aratio of means of 2,90 (P≤0,01) in the «fatty» group (relative abdominal fat content 3,5±0.18%, abdominal fat weight 35,4±6,09 g) relative to the «lean» group (relative abdominal fat content 1,9±0,56%, abdominal fat weight 19,2±5,06 g). Expression of this gene was highly correlated with the relative abdominal fat content (0,70, P≤0,01) and abdominal fat weight (0,70, P≤0,01). The peroxisomeproliferator-activated receptor gamma (PPARG) gene was also up-regulated in the liver with a ratio of means of 3,34(P≤0,01) in the «fatty» group relative to the «lean» group. Correlation of its expression was significant with both the relative abdominal fat content (0,55, P≤0,05) and the abdominal fat weight (0,57, P≤0,01). These data obtained and the data of references will allow the statement that the HMG1A, PPARG and FABP2 genes were candidate genes for abdominal fat deposition in chickens. Searching of rSNPs in regulatory regions of thesegenes could provide a tool for gene-assisted selection

THE ACCUMULATION OF COPPER AND ZINC COMPOUNDS IN BLACK LEACHED SOIL UNDER TECHNOGENIC POLLUTION
DescriptionThe influence of exogenous form of heavy metals intake on their transformation in the soil is determined during the model experiment. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is observed. It is established that Cu accumulates mainly in the fraction connected with organic matter, Zn accumulates in residual fraction and in the fraction connected with ferric oxide and manganese oxide by consecutive fractionation technique

AGRO-BOTANICAL ILLUSTRATION: HISTORY AND CURRENT STATUS
DescriptionThe definition of agro-botanical illustration has been considered in this article, showing its capacity as a resource for analysis in biological research and its importance in the development of agronomy

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

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 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

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

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
