POLYMORPHISM IN PROMOTER OF PROLACTIN GENE AND ITS ASSOCIATION WITH PRODUCTION TRAITS IN CHICKENS
DescriptionProlactin (PRL) - is a peptide hormone. It effects on metabolic processes in mammals and birds. Indel genotype mutations in a prolactin gene were determined in 595 hens and cocks. Polymerase chain reaction (PCR) were used. We studied four different breeds: Cornish, White Russian, Pushkin, Yurlov crower. Homozygous of insertion II, homozygous deletion of DD and heterozygous ID were observed in all groups. The differences in frequencies of genotypes and alleles were observed in all groups. Homozygotes II and allele I (frequency is 0,83) were the most common for Russian white chickens with high egg production and the lack of the instinct of incubation. Prolactin gene deletion was more common for beef Cornish. The frequency of D allele was 0,84. Pushkin chickens proved to be closer to the egg type. A significant number of heterozygotes with this mutation were noted in a population of Yurlov crower. It is recommended to use gene prolactin as a marker of productive indicators in chickens

WORLD AMPELOGRAPHICAL COLLECTION: NNIIViV "MAGARACH" AND SKZNIISiV
DescriptionThe article describes the history of the institute called "Magarach" and the formation of the world's ampelographic collections in the Crimea and Kuban, provides data on the genetic diversity of the original parent Crimean collection of grape, carries out the impact of its long-term ampelo-breeding and genetic work. We have found the best ampelo-genetic rennets, both in the Crimea (zoned in Russia and abroad varieties of Academician Avidzba, Pervanets Magaracha, Jubilee Magarach, Antei magarachsky, Nimrang ustoichivii, Podarok Magaracha, Riesling Magaracha Novoukrainsky Rannii, Granatovii Magaracha, Krymchanin, Rkatsiteli Magaracha, Spartanets Magaracha, Tavkveri Magaracha, Citronnii Magaracha, promising varieties Livya, Solnetchnaja grozd, etc..) and in the Kuban region. Magarach ampelographic collection was and still is the parent of many national collections of gene pools of, the former Soviet republics, including the Russian Federation as well: Anapa ampelographic collection in the North Caucasus NIISiV has 3356 samples collected from 41 countries, including ones from the institute of "Magarach" (about 40%). Using its base we had a comprehensive biological and economic evaluation of the outstanding genotypes for ampelo-genetic and clonal selection – such as zoned Bogotyanovsky, Helios, Dolgogdannii, Kubattik, Libya K, Arathi, Preobragenie, Rochefort K, Chrizolit, Citrine, Anthracite, promising varieties Annie, Baikonur, Gourmet Kra, Memory Master Nesvet Gift, Jubilee Novocherkasska, etc.

The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators

Description
The problem of environmental contamination by heavy metals is significant problem of urbanization. The search of ways of indication heavy metals pollution becomes actual, because of their simplicity and affordability. A widely used test objects for heavy metals pollution indicators are leafy mosses used for bioindication, because they are highly sensitive to any stress factor. The research shows that bioindication with using leafy mosses as test objects is highly effective method definition of heavy metals pollution. Using of bioindication methods are promising techniques for the assessment of the contamination of ecosystems by heavy metals. Through the use of this method, it is possible indication of pollution of the surface layer of air with heavy metals. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems. The accumulation features of heavy metals in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. pylaisiella moss (P. polyantha) accumulates the largest amounts of the following heavy metals: Zn, Cr, Pb, Sr, Ni (Kc to 1.07), and Cu. According to the Kc values, all the studied elements accumulated by pylaisiella moss form the following series of biological uptake: Zn > Pb > Sr > Cr > V > Ni > Cu > Cо. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of heavy metals pollution in different polluted zones

Description
The article reports about the results of the new population of protected herb species studying in the Rostov region and in the Russian Federation - Cymbochasma borysthenica (Pall are given. ex Schlecht.) Klok. & Zoz (Orobanchaceae), registered in 2014 on the northern coast of Mius Liman in the Rostov-on-Don Region. The new habitat is located at considerable distance from the earlier known. The population area has about 200 sq. m, total number – more than 1000 uneven-age specimens of a seed and vegetative origin. Population consists of two cenopopulations one of which lives in community of transitional type from a timyannik to a stony steppe (association: Festuca valesiaca – Cleistogenes bulgarica – Cymbochasma borysthenica – Thymus dimorphus), another – as a part of the stony steppe (association: Festuca valesiaca + Agropyron pectinatum + Galatella villosa), created at the limestone shell rock exits. Cenopopulation in community of transitional type, despite the smaller area (50 sq. m), differs by more number and density. Both cenopopulations are similar in age ranges character and vitality of specimens. They belong to a normal type (capable to vegetative and seed self-maintenance) with a left-side age range that allows estimating them as rather stable, despite very limited area

COMPLEX COMPOST AND ECOLOGICAL NICHE OF LIVING ORGANISMS IN AGROLANDSCAPES
DescriptionEcological niche acts as an important evolutionary function of living organisms in the ecosystem and determines its properties, which are caused by the nutrient requirements, mobility, ability to reproduction, biochemical features, structural features limits tolerance to environmental conditions, opportunities performing certain actions in the specific biocenosis; in the process of divergence (species, their internal and external properties and abiotic characteristics) features of ecological niches are changed , there are new kinds of living organisms and, of course, the formation of new ecological niches

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
