Аннотация: Four birch species are traditionally used for the sap harvesting in Russia. In the report, we discuss their spatial and ecophysiological features as well as the exudation, tapping periods and sap productivity. Biochemical constituents of the living tissues of the birches such as the wood, outer and inner bark, twigs, leaves, buds, roots, and exudated birch sap are also reviewed. We show numerous useful wooden, medicinal, tanning, coloring as well as feeding and decorative properties. Chaga - a fungi-parasite developed on the stems of the birch trees, is mentioned to be famous due to its antitumor and/or especially anti-cancer activity. It is reported that the former birch sap production closed completely at the transition to a market-economy has restarted in the Russian Far East.

Аннотация: Microbial community and population amounts, as well as functional activity, can be concluded to indicate level of human-caused forest ecosystem disturbance at early stage of anthropogenesis. This study identified mocroorganisms useful for bioremediation of disturbed components of forest ecosystems differing in disturbance level. Application of biologically active agents (bacteria and microscopic fungi) was shown to be useful for restoring and improving soil conditions during bioremediation (sanation).

Аннотация: Arctic environments, where surface temperatures increase and sea ice cover and permafrost depth decrease, are very sensitive to even slight climatic variations. Placing recent environmental change of the high-northern latitudes in a long-term context is, however, complicated by too short meteorological observations and too few proxy records. Driftwood may represent a unique cross-disciplinary archive at the interface of marine and terrestrial processes. Here, we introduce 1445 driftwood remains from coastal East Greenland and Svalbard. Macroscopy and microscopy were applied for wood anatomical classification; a multi-species subset was used for detecting fungi; and information on boreal vegetation patterns, circumpolar river systems, and ocean current dynamics was reviewed and evaluated. Four conifer (Pinus, Larix, Picea, and Abies) and three deciduous (Populus, Salix, and Betula) genera were differentiated. Species-specific identification also separated Pinus sylvestris and Pinus sibirica, which account for similar to 40% of all driftwood and predominantly originate from western and central Siberia. Larch and spruce from Siberia or North America represents similar to 26% and similar to 18% of all materials, respectively. Fungal colonization caused different levels of driftwood staining and/or decay. Our results demonstrate the importance of combining wood anatomical knowledge with insight on boreal forest composition for successfully tracing the origin of Arctic driftwood. To ultimately reconstruct spatiotemporal variations in ocean currents, and to better quantify postglacial uplift rates, we recommend consideration of dendrochronologically dated material from many more circumpolar sites.

Аннотация: Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission have been studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi has been revealed, along with a decrease in the enzymatic and respiratory activity of contaminated soil with the relative increase in the fraction of sporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na(2)SO(3) microbiological norm-fixing for technogenic soil ecosystems has been carried out.

Аннотация: Ophiostomatoid fungi colonize the conducting tissues of conifer stems, the phloem and the xylem. These pathogenic fungi penetrate into the stem through injuries made by xylophagous insects vectoring these pathogens. In this study the response of the phloem of Scotch pine (Pinus sylvestris L.) to wounding (treatment 1) was compared with the response to wounding combined with application of high-molecular-weight compounds isolated from the mycelium of the ophiostomatoid fungus Ceratocystis laricicola Redfern & Minter (treatment 2). Both treatments induced the appearance of necrosis in the inner bark, the formation of periderm separating living and dead tissues, and formation of the callus alongside the wound perimeter. In addition, the bark accumulated lignin, bound proanthocyanidins, and resins, with a parallel decrease in the content of free proanthocyanidins, low-molecular-weight carbohydrates, and non-lignin components of the cell wall (P > 0.95). The size of necrotic spots, as well as changes in the content of most substances, were significantly higher in the treatment 2 than in the treatment 1 (P > 0.95). The accumulation of lignin in cell walls of phloem sieve cells was delayed in the treatment 2 as compared with that in the treatment 1. This suggested that the mycelial extract temporarily inhibited lignification at the early stage of the wound response. This disturbance of the cell wall protective transformation led to the hypothesis that the fungal suppressors retard the repair of inner bark injured by insects, thereby favoring the invasion of conifer tissues by ophiostomatoid fungi.

Аннотация: The elicitor activity of compounds extracted from the mycelia of six species of phytopathogenic fungi was assessed from the sizes of necrotic lesions on the external surface of the living trunk phloem of five coniferous species inhabiting Siberia: Siberian larch (Larix sibirica L.), Scotch pine (Pinus sylvestris L.), Siberian spruce (Picea obovata Ledeb.), Siberian fir (Abies sibirica L.), and cedar pine (Pinus sibirica (Rupr.) Mayr.). The compounds for inoculation were extracted from the mycelium of ascomycetes imperfect, and basidium fungi; the living mycelia of these fungi were also used. The fungal extract or mycelium was placed into the hollows 7 mm in diameter in the trunk bark. Infection triggered the formation of hypersensitivity necrotic lesions in the inner bark exceeding in size those appeared after control wounding of four tree species (larch, pine, spruce, and cedar); fir was an exclusion. In experiments with tree trunks and conifer calluses, a dependence of immune response parameters (the sizes of necrotic lesions and the content of lignin and bound proanthocyanidins) on the quantity of the fungal preparation was elucidated. The largest necrotic lesions appeared after injection of 500 mu g of the fungal preparation into the hollow in the trunk, and its higher quantities did not increase the indices measured. The size of the necrotic lesion on the trunk bark is supposed to be used as a promising index characterizing the level of tree immunity and tolerance under various ecological conditions.

Аннотация: The introduction of Trichoderma viride spores (10(8) CFU per 1 cm(2)) essentially changed the structure of micromycetes in the soils of tree nurseries in Krasnoyarsk region. During the first 20 days, in the variants with dark gray forest soils and podzolized chernozems, the total number of fungi decreased by 3-4 and 1.5 times, respectively, as compared to that in the control plots. During the intense development of the introduced microbes, the species composition of the soil fungi changed considerably. The treatment of Scots pine seeds with metabolites of Trichoderma fungi, as well as Pseudomonas and Bacillus bacteria, in the form of water suspensions, biopreparations, and dry spores promoted an increase in the yield of seedlings and improve their morphometric parameters. At the end of the growing period, the treatment with Trichoderma and the biopreparation on its basis increased these parameters, on average, by 18-70%, and the treatment with bacteria increased the same parameters by 13-15%. The application of microbial preparations improved the phytosanitary state of the soils in the studied tree nurseries. The use of the strains of indigenous microorganisms might be feasible for solving bioremediation problems more successfully in particular regions.

Аннотация: Two methods for evaluation of pine stand vigor were tested on permanent sample plots near Krasnoyarsk City: visual evaluation and exposure to fungal metabolites. In the first case, forest vigor was estimated using the six-point system of the Sanitary Regulations of the Russian Federation as the mean score for 200 trees on the sample plots. In the second case, the vigor was evaluated from the size of the necrotic spot on inner bark of the tree after inoculation of 22-25 randomly chosen pines with the extract of fungus Ceratocystis laricicola Redfern and Minter. The necrotic spot size was significantly larger in pines from polluted forest as compared to background one. This points to the decrease in infection protection of trees affected by pollution, although visual evaluation of the stand vigor could not distinguish the polluted and background stands.

Аннотация: Callus cultures of Siberian larch (Lar ix sibirica Ledeb.) and Siberian spruce (Picea obovata Ledeb.) were used to demonstrate the elicitor activity of two ophiostomatoid fungal species, Ceratocystis laricicola and Ceratocystis polonica, as the pioneer settlers on larch and spruce, respectively. The extract from C. laricicola mycelium stimulated the accumulation of lignin in larch cells by 37% and that of hound proanthocyanidins by 25%. In spruce callus cultures, C. laricicola and C. polonica increased the bound PA content by 25 and 46%, respectively. In the callus cultures of larch and spruce, the addition of extract of C. laricicola increased the concentration of p-hydroxybenzoic acid 13-fold and nearly 4-fold, respectively. The metabolic characteristics of accumulation of phenolic compounds in conifer cells are discussed.

Аннотация: Species of Leptographium are well-known inhabitants of conifers in the Northern Hemisphere, in which they cause a blue-stain. They are also known to be associated with insects, especially bark beetles (Coleoptera: Scolytidae). Surveys of dying stands of Siberian fir (Abies sibirica) have resulted in the consistent isolation of an unknown Leptographium from the galleries of the fir sawyer beetle, Monochamus urussovi (Coleoptera: Cerambycidae). This fungus is responsible for the blue-stain in living trees. Comparison with known species of Leptographium led to the conclusion that it had not been previously described, and the name Leptographium sibiricum sp. nov, is introduced here.

Аннотация: Soils in the tree nurseries studied were characterized by a lower species diversity of fungi than adjacent virgin soils. In particular, the relative abundances of representatives of the genera Mucor Chaetomium, and Trichoderma in the nursery soil were two times lower than in adjacent virgin soils. On the other hand, the nursery soil exhibited greater abundances of fungi of the genus Fusarium, which are causative agents of many diseases of conifer seedlings. To appreciate the efficiency of biocontrol of the infectious diseases of conifer seedlings, we introduced several indigenous Trichoderma strains into the nursery soil and found that this affected the species composition of soil microflora considerably. Changes in the species composition of mycobiota beneficially influenced the phytosanitary state of soils and reduced the infectious lodging of conifer seedlings.

Аннотация: The number and the biomass of microorganisms were determined in the soils of the floodplain and islands in the Selenga River delta. The population of fungi in the soils studied was low. The number of saprotrophic prokaryote microorganisms varied from 10(6)-10(8) CFU/g of soil in the upper horizons to 10(4)-10(5) CFU/g in the lower horizons of the soils. This pattern is typical for most zonal soils. The microbial biomass in the floodplain soils was 2-4 times as high as that in the soils of the islands. The number of microorganisms of different ecologic-trophic groups participating in the nitrogen and carbon mobilization was much lower than that in the hydromorphic soils of the Transbaikal region or in the cryogenic soils of the Angara River basin (Irkutsk district). The low coefficient of microbiological mineralization and the low coefficient showing the lack of nitrogen (coefficient of oligotrophness) in the soils indicated the weak processes of organic matter decomposition in the soils studied. During the season investigated (August-September), the bacterial complexes in all the soils were dominated by bacteria of the genera Bacillus, Pseudomonas, and Aquaspirillum. In the floodplain soils, streptomycetes constituted a considerable part of the microbial complexes of the floodplain soils, whereas, in the soils of the islands, their number was minor.

Аннотация: This study was carried out to investigate the interaction between basidiomycetes and Ophiostomataceae fungi that were able to inhibit the growth of blue stain fungi and to decolorize its dark pigments. Twenty-eight isolates belonging to 18 species of basidiomycetes and eighteen isolates of 11 blue stain fungi, mainly from Ophiostomataceae family, were used. The dual culture technique was adopted to study the interaction between basidial and blue stain fungi isolates. The ability of basidial cultures to decolourize dark pigments of ophiostomatoid fungi was the main characteristics estimated during this investigation. Antrodiella hoehnelii (S28/91), Bjerkandera fumosa (137), Gleophyllum odoratum (124), and Trametes versicolor (1318/91) cultures were found to be the most active in decreasing dark colour of blue stain fungi colonies. The cultures were recommended for further development as agents of biopulping and control of blue stain fungi in wood chips.

Аннотация: In this article, we report observations made during thirteen years on foliar fungal pathogens attacking European and Eurasian woody broadleaved species in Siberian arboreta and cities and discuss the possibility of using such data for detecting exotic pathogens that may represent a danger for European tree and shrub species, should these pathogens be introduced into Europe. A total of 102 cases of symptomatic infections (fungus-host plant associations) involving 67 fungal species were recorded on 50 of the 52 European and Eurasian woody plant species. All but four of the fungi found during the surveys were previously reported in Europe. However, 29 fungus-host plant associations are apparently new to science, suggesting that complexes of cryptic species differing in their host range and geographic range may occur. Seventeen percentage of associations were given a high damage score, that is, more than 50% of plant area was attacked, for at least some localities. In nearly half of the cases, fungus-host plant associations were found to be very frequent, that is, occurring every year and at all locations where the plant was inspected. A list of pathogen-host associations in Siberia deserving further investigation is provided, either because the pathogen is not yet recorded in Europe or because the pathogen-host association has not yet been reported, and the damage is high or, finally, because the damage and infestation level is unusually high in known associations. Further studies should involve molecular characterization of these foliar pathogens and their host range testing.

Аннотация: The effects of pentachlorophenol (PCP) and 2-chlorophenol (2CP) on white rot fungi, Abortiporus biennis, Cerrena unicolor, Gloeophyllum odoratum, and Trametes versicolor were investigated. With the exception of C. unicolor and A. biennis, concentrations of PCP higher than 50 ppm inhibited fungal growth completely. However, extreme concentrations of PCP (500 ppm) caused a 61 % increase in growth of C. unicolor compared to the control culture within 14 days. When initial PCP concentrations were 50 ppm A. biennis and C. unicolor achieved, respectively, 87 % and 78 % of chlorophenol transformation within 3 days. However, when 2,5-dimethylaniline (0.2mM) was added to the C. unicolor culture, 98 % of PCP transformation was achieved after one hour. Under the same conditions, A. biennis transformed 44 % of PCP. Both chlorophenols are completely removed, when laccase activity reaches its maximum. In conclusion, among the four fungi investigated, C. unicolor and A. Biennis were very effective in transforming PCP and 2-CP. This biotransformation was greatly intensified by 2,5-dimethylaniline and accompanied by an increase in laccase activity.

Аннотация: Effect of tannin and non-volatile components of lesion resin on the growth of blue-stain fungi - Ceratocystis laricicola, C. polonica, Ophiostoma minus, Leptographium sp. and Ophiostoma sp. - the primary invaders of conifers in Siberia (Russia), has been studied. The fungi under study exhibited tolerance to plant's defensive substances in bioassays. The cultures of Leptographium sp., C. polonica, and Ophiostoma sp. proved to be the most tolerant to tannin. In the range between 0.05 and 0.15% tannin concentration their growth tended to stabilize. Less tolerant to tannin were C. laricicola and O. minus. With an increase in tannin concentration their biomass gradually decreased. The fungi more tolerant to tannin regulated the medium pH about 5.0 and higher, white the species which were less tolerant preferred lower pH values. Lesion resins of conifers differed in their inhibitory effect on fungal growth. Fir resin had the greatest inhibitory effect of all the conifer resins tested, causing reduction to 50-60% in fungal growth. When fungi were grown on the resin of any other conifer, the reduction in the linear growth rate did not exceed 20 to 30%. The assumption that fungi are more tolerant to the resin of a host plant than to that of a non-host plant has not been confirmed.

Аннотация: Effect of defoliation on resistance response of Siberian fir, Abies sibirica Ledeb., to fungal inoculation was investigated within three even-aged fir stands damaged by Siberian moth, Dendrolimus superans sibiricus Tschetw., and located in the Krasnoyarsk Territory (Central Siberia). Histological changes in tissues, accompanying the resistance response were examined in 30 fir trees (90-130 years old) of different defoliation degree (50, 75, 100 %) six weeks after single inoculation with Leptographium sp, vectored by Monochamus urussovi Fisch. (Coleoptera: Cerambycidae). It was recorded that the rate and intensity of defence response of phloem and xylem tissues to inoculation as well as percent of trees infested by the insect-vector differed significantly in dependence of defoliation degree. Trees of 50 percent defoliation significantly differed from trees of more severe defoliation in all parameters of defence response and percentage of colonisation by the beetle. The trees defoliated to 75 and 100% did not differ significantly in defence response activity and the number of the trees attacked by M. urussovi Strong difference in resistance to inoculation and colonisation by the beetle was recorded between trees defoliated in the current year and in the previous year. All infested by M, urussovi trees were characterised by the epidemic level of frequency of blue-stain fungi associated with this insect. The tendency was recorded to a decreased frequency of the pathogenic Ophiostoma sp. and a more frequent occurrence of the saprophyte O. curvicollis in trees defoliated in previous year which lost ability to defend against wounding and fungal infection.

Аннотация: Stable isotope analysis is a powerful tool in the study of soil organic matter formation. It is often observed that more decomposed soil organic matter is C-13, and especially N-15-enriched relative to fresh litter and recent organic matter. We investigated whether this shift in isotope composition relates to the isotope composition of the microbial biomass, an important source for soil organic matter. We developed a new approach to determine the natural abundance C and N isotope composition of the microbial biomass across a broad range of soil types, vegetation, and climates. We found consistently that the soil microbial biomass was N-15-enriched relative to the total (3.2 parts per thousand) and extractable N pools (3.7 parts per thousand), and C-13-enriched relative to the extractable C pool (2.5 parts per thousand). The microbial biomass was also C-13-enriched relative to total C for soils that exhibited a C3-plant signature (1.6 parts per thousand), but C-13-depleted for soils with a C4 signature (-1.1 parts per thousand). The latter was probably associated with an increase of annual C3 forbs in C4 grasslands after an extreme drought. These findings are in agreement with the proposed contribution of microbial products to the stabilized soil organic matter and may help explain the shift in isotope composition during soil organic matter formation.

Аннотация: The significant growth in applications of silver nanoparticles across -various branches of industry as well as in consumer products has caused concerns that nanosilver may have a toxic effect on the environment and human health and may have implications for eco-terorism. This paper presents research on antimicrobial effects of silver nanoparticles. We studied the cytotoxicity of silver nanoparticles via an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) assay that measures cell activity through the mitochondrial cleavage of a molecule that exhibits a change of colour that can be measured spectrophotometrically. NIH-3T3 (Swiss mouse embryo), HEP-G2 (human hepatocellular carcinoma), A-549 (human lung carcinoma), PC-12 (rat adrenal pheochromocytoma), and Colo-320 (human colon adenocarcinoma) cells were chosen in order to study different possible absorption paths of nanoparticles into the organism and various areas of particle accumulation in the body. The obtained MTT test results have shown that silver nanoparticles with concentrations of ∼1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. © Springer Science+Business Media B.V. 2011.
