Abstract
A comparative study of the biochemical composition of the groundwater bodies of 10 varieties of artichoke from the collection of Central botanical garden in the autumn and spring mounted pronounced dependence of the integral level of nutritional and vitamin value of raw pieces of this type of aggregate 8 defining characteristics of high-quality supplies of plants and tubers harvesting time. It is shown that, regardless of the time of year, the highest level of integrated nutritional and vitamin value of groundwater bodies characterized by the variety of artichoke, such as Skorospelka and Topinsolnechnik, indicating that they are the most promising for commercial cultivation in the conditions of Belarus.

Abstract
Three lines of transgenic tobacco plants (Nicotiana tabacum L. cv. Petit Havana SR1) expressing recombinant Saccharomyces cerevisiae ALA-synthase gene that contains an information for targeting peptide providing penetration of the enzyme to mitochondria (lines 1.1, 1.3, 1.7) and one line expressing gene of the ALA-synthase that is synthesized and localized in cytoplasm were obtained (line 2.1). All transgenic plants possessed by increased ALA-synthesizing ability and were characterized by improved growth parameters. Higher content of photosynthetic pigments - chlorophyll and carotenoids as compared to wild-type plants was also registered in plants of the line 2.1. The received transgenic plants can serve as model for research of a role of endogenous ALA in providing photosynthetic activity of chloroplast and forming of plant stress resistance that will be used for creating the biotechnologically improved cultivars.

Abstract
The examination of the 44 blue lupine (L. angustifolius) samples with molecular markers of 4 economically important traits was conducted. The study revealed polymorphism of markers TaLi (pod shattering), IucLi (low content of alkaloids), AnManM1 (resistance to anthracnose) in given collection.

Abstract
A new recombinant strain of Escherichia coli pBtdac, producing diadenylate cyclase Bacillus thuringiensis has been constructed. The amount of the diadenylate cyclase produced by the strain is 32 mg per 1 L of culture broth. The substrate specificity and stability of the produced enzyme has been studied. Application of the purified diadenylate cyclase for preparative (600 mg) cyclic di-AMP synthesis has been demonstrated.

Abstract
A new Ponto-Caspian species of fish - the black sea sprat Clupeonella cultriventris (Nordmann, 1840) have been confirmed in the water bodies of Belarus. Now composition fish fauna of Belarus includes 65 species, 8 species penetrated to the territory of Belarus from the Ukraine due to anthropogenic causes by the expansion of the range via the River Dnieper.

Abstract
Species diversity of vertebrate predators of Naliboki Forest is rich in species composition (44-48 species), high dominance species structure is in the warm season and is alignment in the cold season. Seasonal differences of the structure predator species is associated with changes in the density of their population due to demographic processes, migration and hibernation. In the size structure of vertebrate predators dominated by small species, in the warm season in this size group dominated by snakes (mostly grass snake), and in the cold season - weasel. Seasonal differences structure of predator guilds due to the fact that during the warm season absolutely consumers of amphibians dominated, at the beginning of the cold season consumers of rodents and insectivores dominated and midsize consumers of birds and mammals well represented, and at the end of the cold season to the fore consumers fell, and only then there are consumers rodents and insectivores and consumers midsize birds and mammals.

Abstract
Six species of fungi of the genus Phyllactinia Lev. parasitizing on 17 species plants-hosts were found on the territory of Belarus. The key for the determination of the species, morphological features of pathogens and the diseases of plants-hosts are given.

Abstract
The peptide composition of obtained enzymatic hydrolysate of whey proteins was determined. Also the parameters of its acute toxicity, antigenic and sensitizing activity were researched. The examined sample according to physicochemical, immunochemical and organoleptic properties corresponds to characteristics of partial hydrolysates for functional food products. Hydrolysed protein component possesses a weak sensitizing capacity.

Abstract
Elective conditions were selected in order to ensure effective allocation of acetic acid bacteria. From grape berries, apples, red currant and malt were allocated 22 strain acetic acid bacteria, which include representatives of the genera Acetobacter and Gluconobacter. Among the isolates were found 3 strains with higher acetic acid production. Among them - the strain Acetobacter sp. Vin3.3, which is superior the collectible industrial strain A. aceti N 1 in productivity.

Abstract
Atherosclerosis experimental model with atherogenic cholesterol causes damage to the coronary arteries of rats revealed morphological methods after 15 days of using the diet. These changes are similar to changes on the stage to the presence of lipids that is supported by studies at the ultrastructural level. After 60 days the rats in the coronary arteries prevail processes characteristic of the lipoidosis. After 180 days of the experiment revealed the progression liposclerotic processes.

Abstract
Old concrete fortifications, which are numerous on the territory of Belarus, are refugiums for population and conservation of ecologically different mosses, including rare and endangered species, mainly calciphilous. These structures are analogous to the rocky calcareous rocks. In view of specific these anthropogenic ecotopes that are unusual for a natural complex of Belarus, the need to assess the most important factors for the expansion of mosses to such facilities emerged. One of the largest complexes of fortifications - Grodno fortress is taken as a case study. The main limiting factors in the distribution of bryophytes on fortifications identified here. The main limiting factors are the type of substrate, air-water regime and substrate surface.

Abstract
Acute carbon tetrachloride-induced rat liver damage (4 g/kg) after 24 h was accompanied by a significant reduction in succinate- and glutamate-dependent mitochondrial respiration rate in state 3 (by 65 %, and by 50 %, respectively). The acceptor control ratio and respiration control ratio approached to 1, reflecting the loss of respiration control. The mitochondrial alterations were associated with oxidation of intramitochondrial GSH, the inhibition of succinate dehydrogenase (complex II) and the rise of blood plasma nitric oxide level. Melatonin administration under CCl4-induced intoxication (three times at doses of 10 mg/kg) did not cause a pronounced recovery of mitochondrial functional activity, but prevented an increase in nitric oxide level in the blood plasma of intoxicated animals and enhanced the rate of succinate oxidation in state 3 by 30 % (p < 0.05).

Abstract
The information about the helminth fauna of Eurasian water shrew in Belarus was presented. 23 species of helminths were found in this insectivorous mammal. More than of theirs (21) in south-west Belarus are noted. 25 Eurasian water shrews were investigated there during 1996-2011, and in 23 animals (92.0 %) were found 16 species of helminths: 8 trematode species, 3 cestode species and 5 nematode species. Trematode Neoglyphe locellus (Kossack, 1910) have been registered more often. Cestode Triodontolepis sumavensis (Prokopie, 1957), nematodes Capillaria konstantini Romashov, 1999 and Longistriata neomi Lubarskaja, 1962 for the first time are find in Belarus.

Abstract
The possibility of refined sunflower oil replacing for surfactants and exopolysaccharides synthesis by Acmetobacter calcoaceticus IMV B-7241 and Acinetobacter sp. ІМВ В-7005, on cheaper and affordable substrates (unrefined, waste after frying potato and meat oil) was shown. The quantity of synthesized surfactants and exopolysaccharides on waste sunflower oil was higher than on purified (refined) substrate with using inoculum grown on refined oil.

Abstract
Different physiological and biochemical processes mediated by nanoparticles in plants are reviewed. It can be concluded that the morphological and physiological characteristics of plants (the presence of polysaccharides of the cell wall, vacuole, the root system, photosynthesis, mineral nutrition, water exchange) could provide some specific interactions nanoparticles with plant organisms. It is very important to mark out plant nanophysiology (nanophytophysiology) as a significance branch of nanobiology.
