Abstract	Data on concentrations and molecular structure of paraffin hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) present in dissolved and particulate forms in the surface microlayer and in bottom sediments of the inshore and central parts of the Black Sea are presented. Distribution of hydrocarbons in these regions is chiefly governed by the independent geochemical background distribution. Industrial pollutions play a noticeable role in the northwestern and southeastern zones of the basin and that is expressed by increase in concentrations of n-alkanes and PAHs (particularly in suspended matter) and increase in the ratios of industrially derived PAHs to biogenic PAHs.

Abstract	Bitumoid contents in metalliferous sediments from axial parts of the East Pacific Rise (EPR) have been studied. Maximal concentrations of bitumoid matter and aromatic hydrocarbons have been found in the axial zones of the EPR as a result of hydrothermal processes and accumulation of endogenous matter in the sediments. Distribution of bitumoids and hydrocarbons coincides with deposition of ore minerals that indicates similarity of their sources.

Abstract	Use of bituminological parameters for determining origin of organic matter in sediments from the deformation zone in the Central Indian Ocean is considered. It is shown that relatively high concentrations of hydrocarbons enriched in aromatic structures (above 60%) were detected in bitumoids from the region of extensive tectonic deformations of the sedimentary cover. The main molecular structures of polycyclic aromatic hydrocarbons (PAH) are homologues of naphtylene (40-60% rlt.), and phenanthrene (15-40% rlt.), biphenyl (19-30% rlt.) and benzfluorene homologues (up to 13% rlt.). Pyrene, 1.12-benzperylene, and chrysene homologues are found in minor amounts. Such distribution of PAH is close to that in carbonic matter of high-temperature hydrothermal associations. It is shown that sediments from fracture zones and from boundaries of deformed blocks contain organic components of deep high-temperature origin.

Abstract	Main conclusion: Fiber-like cells with thickened cell walls of specific structure and polymer composition that includes (1 → 4)-β-galactans develop in the outer stem cortex of several moss species gametophytes. The early land plants evolved several specialized cell types and tissues that did not exist in their aquatic ancestors. Of these, water-conducting elements and reproductive organs have received most of the research attention. The evolution of tissues specialized to fulfill a mechanical function is by far less studied despite their wide distribution in land plants. For vascular plants following a homoiohydric trajectory, the evolutionary emergence of mechanical tissues is mainly discussed starting with the fern-like plants with their hypodermal sterome or sclerified fibers that have xylan and lignin-based cell walls. However, mechanical challenges were also faced by bryophytes, which lack lignified cell-walls. To characterize mechanical tissues in the bryophyte lineage, following a poikilohydric trajectory, we used six wild moss species (Polytrichum juniperinum, Dicranum sp., Rhodobryum roseum, Eurhynchiadelphus sp., Climacium dendroides, and Hylocomium splendens) and analyzed the structure and composition of their cell walls. In all of them, the outer stem cortex of the leafy gametophytic generation had fiber-like cells with a thickened but non-lignified cell wall. Such cells have a spindle-like shape with pointed tips. The additional thick cell wall layer in those fiber-like cells is composed of sublayers with structural evidence for different cellulose microfibril orientation, and with specific polymer composition that includes (1 → 4)-β-galactans. Thus, the basic cellular characters of the cells that provide mechanical support in vascular plant taxa (elongated cell shape, location at the periphery of a primary organ, the thickened cell wall and its peculiar composition and structure) also exist in mosses.

Abstract	Bituminous substances in metalliferous sediments from the region of the triple junction in the Indian Ocean were studied. Specific peculiarities of their structure confirming location in "hot conditions" were revealed. Hydrocarbons are genetically connected with hydrothermal matter, and thus they could be considered as a geochemical indicator of hydrothermal processes in the ocean.

Abstract	The cellulose-enriched tertiary cell walls present in many plant fibers have specific composition, architecture, machinery of formation, and function. To better understand the mechanisms underlying their mode of action and to reveal the peculiarities of fibers from different plant species, it is necessary to more deeply characterize the major components. Next to overwhelming cellulose, rhamnogalacturonan I (RG-I) is considered to be the key polymer of the tertiary cell wall; however, it has been isolated and biochemically characterized in very few plant species.

Abstract	The cellulose-enriched tertiary cell walls present in many plant fibers have specific composition, architecture, machinery of formation, and function. To better understand the mechanisms underlying their mode of action and to reveal the peculiarities of fibers from different plant species, it is necessary to more deeply characterize the major components. Next to overwhelming cellulose, rhamnogalacturonan I (RG-I) is considered to be the key polymer of the tertiary cell wall; however, it has been isolated and biochemically characterized in very few plant species. Here, we add RG-I to the list from the phloem fibers of the Phaseolus vulgaris stem that was isolated and analyzed by nuclear magnetic resonance (NMR), dynamic light scattering, and immunolabeling, both within tissue and as an isolated polymer. Additionally, fibers with tertiary cell walls from nine species of dicotyledonous plants from the orders Malphigiales, Fabales, and Rosales were labeled with RG-I-related antibodies to check the presence of the polymer and compare the in situ presentation of its backbone and side chains. The obtained results confirm that RG-I is an obligatory polymer of the tertiary cell wall. However, there are differences in the structure of this polymer from various plant sources, and these peculiarities may be taxonomically related.

Abstract	The key problems of development of agrarian business were analyzed. Low dynamic potential of renewal of production process, lowering of employment in agricultural business, people abandoning rural localities, and inefficient system of agricultural pattern are mostly those problems. Authors established that among financial instruments intended to solve those problems are the system of budget program special purpose funding and bank credit products and they are the target to implement project decisions in the field of agribusiness. Agricultural credit cooperation will allow solving effectively the problems of small-scale agricultural industries and farming. The dynamics of the financial institutions within the specified field was analyzed and measures to activate the development of agricultural credit cooperation areadvised.

Abstract	Cellulose synthesising complex consists of cellulose synthase (CESA) subunits encoded by a multigene family; different sets of CESA genes are known to be expressed during primary and secondary cell wall formation. We examined the expression of LusCESAs in flax (Linum usitatissimum L.) cellulosic fibres at various stages of development and in the course of graviresponse by means of RNA-Seq and quantitative PCR. Transcripts for both primary and secondary cell wall-related CESAs were abundant in fibres depositing highly cellulosic tertiary cell walls. Gravistimulation of flax plants temporally increased the abundance of CESA transcripts, specifically in phloem fibres located at the pulling stem side. Construction of coexpression networks for LusCESAs revealed that both primary and secondary cell wall-related CESAs were involved in the joint coexpression group in fibres depositing tertiary cell walls, as distinct from other tissues, where these genes were within separate groups. The obtained data suggest that fibres depositing tertiary cell walls have a specific mechanism of cellulose biosynthesis and a specific way of its regulation.
