Аннотация: Changes in the levels of ascorbic acid (AA), its oxidized form, dehydroascorbic acid (DHA), and uronic acids as initial precursors for the AA synthesis were studied as related to the degree of xylem and phloem cell development in the course of early and late wood formation in the trunks of Scots pine (Pinus sylvestris L.). The cells of mature and conducting phloem, cambial zone, differently developed cells in the zones of cell enlargement and maturation were obtained by successive scraping tissue layers from trunk segments of 20-25-year-old trees; tissue identification was checked anatomically and histochemically. The contents of compounds tested were calculated per dry weight and per cell basis. We found great differences in the contents of AA and DHA and also in their ratio in dependence of the wood type developing in the pine trunks during growth period and on the stage of differentiation of xylem and phloem cells. Changes in the AA content during xylem cell differentiation were accompanied by changes in the content of uronic acids. The amounts of AA, DHA, and uronic acids were the highest at the stage of early lignification and reduced with tracheid maturation. The AA to DHA ratio changed differently in the course of early and late xylem lignification. It reduced from the start of lignification to the formation of early mature xylem and, in contrast, increased in mature late wood; this indicates a difference in the level of redox processes in these tissues.

    VARIATION AMONG AND WITHIN MOUNTAIN BIRCH TREES IN FOLIAGE PHENOLS, CARBOHYDRATES, AND AMINO-ACIDS, AND IN GROWTH OF EPIRRITA-AUTUMNATA LARVAE
[Text] / J. . SUOMELA, V. . OSSIPOV, E. . HAUKIOJA // J. Chem. Ecol. - 1995. - Vol. 21, Is. 10. - P1421-1446, DOI 10.1007/BF02035143. - Cited References: 81 . - 26. - ISSN 0098-0331

Аннотация: Leaf quality of the mountain birch (Betula pubescens ssp. tortuosa) for herbivores was studied at several hierarchical levels: among trees, among ramets within trees, among branches within ramets, and among short shoots within branches. The experimental units at each level were chosen randomly. The indices of leaf quality were the growth rate of the larvae of a geometrid, Epirrita autumnata, and certain biochemical traits of the leaves (total phenolics and individual phenolic compounds, total carbohydrates and individual sugars, free and protein-bound amino acids). We also discuss relationships between larval growth rate and biochemical foliage traits. Larval growth rates during two successive years correlated positively at the level of tree, the ramet, and the branch, indicating that the relationships in leaf quality remained constant between seasons both among and within trees. The distribution of variation at different hierarchical levels depended on the trait in question. In the case of larval growth rate, ramets and short shoots accounted for most of the explained variation. In the case of biochemical compounds, trees accounted for most of the variance in the content of total phenolics and individual low-molecular-weight phenolics. In the content of carbohydrates (total carbohydrates, starch, fructose, glucose, and sucrose) and amino acids, variation among branches was generally larger than variation among trees. Variation among ramets was low for most compounds. No single leaf trait played a paramount role in larval growth. Secondary compounds, represented by phenolic compounds, or primary metabolites, particularly sugars, may both be important in determining the suitability of birch leaves for larvae. If phenols are causally more important, genet-specific analyses of foliage chemistry are needed. If sugars are of primary importance, within-genet sampling and analysis of foliage chemistry are necessary.

    LOCATION OF ARABINOGALACTAN PROTEINS IN XYLEM OF SIBERIAN LARCH
[Text] / G. F. ANTONOVA, V. V. STASOVA // SOVIET PLANT PHYSIOLOGY. - 1990. - Vol. 37, Is. 4. - P547-554. - Cited References: 23 . - 8. - ISSN 0038-5719

Аннотация: We conducted a comparative study on the composition of water soluble carbohydrate-protein complexes of primary cell walls and cytoplasm in xylem cells of Siberian larch (Larix sibirica Ldb.). Preparations were obtained in the process of isolating protoplasts from xylem cells at the stage of elongation. Water-soluble high-molecular-weight compounds were fractionated on DEAE cellulose. It was found that the dominant fraction in composition of these compounds consists of a carbohydrate-protein complex. Comparison of the composition of neutral sugars, uronic acids, and amino acids of these complexes showed that water-soluble arabinogalactan proteins were absent in the cytoplasm, but present in the solution after plasmolysis. They were bound with pectins and arabinoxylans, detected in solutions obtained after isolation and purification of protoplasts, and capable of forming a gel at low water content and low temperature. It is hypothesized that arabinogalactan proteins are components of primary cell walls, that they are located for the most part on the surface, and that their solubility in an aqueous medium depends upon binding with pectins of the middle plate and with other cell wall components.

    Aspect-vegetation complex effects on biochemical characteristics and decomposability of soil organic carbon on the eastern Qinghai-Tibetan Plateau
/ N. -N. Zhao [et al.] // Plant Soil. - 2014. - Vol. 384, Is. 1-2. - P289-301, DOI 10.1007/s11104-014-2210-x . - ISSN 0032-079X

Lignin Microbial biomass -- Mineralization -- Non-cellulosic sugars -- Soil organic carbon quality

Аннотация: Background Meadows and shrublands are two major vegetation types on the Qinghai-Tibetan Plateau, but little is known about biochemical characteristics and its relation to decomposability of soil organic carbon (OC) under these two vegetation types. The present study was designed to evaluate effects of aspect-vegetation complex on biochemical characteristics and decomposability of soil OC. Methods Two hills were randomly selected; both with vegetation being naturally divided into southward meadows and northward shrublands by a ridge, and soils were sampled at depths of 0-15 and 15-30 cm, along contours traversing the meadow and shrubland sites. Particulate (particle size 2-0.05 mm) OC and nitrogen (N), microbial biomass C and N, non-cellulosic sugars, and CuO lignin were analyzed, and OC mineralization was measured for 49 days at 18 and 25 °C under laboratory incubation, respectively. Results More than half of soil OC was present as particulate fraction across all samples, indicating the coarse nature of soil organic matter in the region. Averaging over depths, shrublands contained 87.7 - 114.1 g OC and 7.7 - 9.3 g N per kg soil, which were 63 - 78 and 26 - 31 % higher than those in meadows, respectively. Meanwhile the C/N ratio of soil organic matter was 11.4 - 12.3 under shrublands, being 29 - 40 % higher than that under meadows. Soil OC under meadows was richer in noncellulosic carbohydrates and microbial biomass in the 0-15 and 15-30 cm depths but contained less lignin in the 15-30 cm depth. Ratios of microbially- to plant-derived monosaccharides and between acid and aldehyde of the vanillyl units were greater in soils under shrublands, showing more abundant microbially-derived sugars and microbially-transformed ligneous substances in OC as compared to meadow soils. By the end of 49 days' incubation, total CO2-C evolution from soils under meadows was 15.0-16.2 mg g-1 OC averaging over incubation temperatures and soil depths, being 27-55 % greater than that under shrublands. Across all soil samples over two sites, total CO2 - C evolved per g OC at either 18 or 25 °C was closely correlated to enrichments of noncellulosic carbohydrates and microbial biomass. This indicates that the greater soil OC decomposability under meadows was associated with its larger abundances of readily mineralizable fractions compared with shrublands. However, temperature increase effect on soil OC decomposability did not differ between the two types of vegetation. Conclusions Our findings suggest that the aspect-vegetation complex significantly affected pool size, biochemical characteristics, and decomposability of soil OC on the northeastern edge of Qinghai-Tibetan Plateau. However, the response of soil OC decomposability to temperature was similar between southward meadows and northward shrublands. © 2014 Springer International Publishing Switzerland.

    Examining the response of needle carbohydrates from Siberian larch trees to climate using compound-specific δ13C and concentration analyses
/ K. T. Rinne [et al.] // Plant Cell Environ. - 2015. - Vol. 38, Is. 11. - P2340-2352, DOI 10.1111/pce.12554 . - ISSN 0140-7791

Carbon isotope -- Central Siberia -- Larix gmelinii Rupr. -- Needle sugar concentration -- Larix -- Larix gmelinii

Аннотация: Little is known about the dynamics of concentrations and carbon isotope ratios of individual carbohydrates in leaves in response to climatic and physiological factors. Improved knowledge of the isotopic ratio in sugars will enhance our understanding of the tree ring isotope ratio and will help to decipher environmental conditions in retrospect more reliably. Carbohydrate samples from larch (Larix gmelinii) needles of two sites in the continuous permafrost zone of Siberia with differing growth conditions were analysed with the Compound-Specific Isotope Analysis (CSIA). We compared concentrations and carbon isotope values (δ13C) of sucrose, fructose, glucose and pinitol combined with phenological data. The results for the variability of the needle carbohydrates show high dynamics with distinct seasonal characteristics between and within the studied years with a clear link to the climatic conditions, particularly vapour pressure deficit. Compound-specific differences in δ13C values as a response to climate were detected. The δ13C of pinitol, which contributes up to 50% of total soluble carbohydrates, was almost invariant during the whole growing season. Our study provides the first in-depth characterization of compound-specific needle carbohydrate isotope variability, identifies involved mechanisms and shows the potential of such results for linking tree physiological responses to different climatic conditions. © 2015 John Wiley & Sons Ltd.

Аннотация: Significant gaps still exist in our knowledge about post-photosynthetic leaf level and downstream metabolic processes and isotopic fractionations. This includes their impact on the isotopic climate signal stored in the carbon isotope composition (delta C-13) of leaf assimilates and tree rings. For the first time, we compared the seasonal delta C-13 variability of leaf sucrose with intra-annual, high-resolution delta C-13 signature of tree rings from larch (Larix gmelinii Rupr.). The trees were growing at two sites in the continuous permafrost zone of Siberia with different growth conditions. Our results indicate very similar low-frequency intra-seasonal trends of the sucrose and tree ring delta C-13 records with little or no indication for the use of 'old' photosynthates formed during the previous year(s). The comparison of leaf sucrose delta C-13 values with that in other leaf sugars and in tree rings elucidates the cause for the reported C-13-enrichment of sink organs compared with leaves. We observed that while the average delta C-13 of all needle sugars was 1.2% more negative than delta C-13 value of wood, the delta C-13 value of the transport sugar sucrose was on an average 1.0% more positive than that of wood. Our study shows a high potential of the combined use of compound-specific isotope analysis of sugars (leaf and phloem) with intra-annual tree ring delta C-13 measurements for deepening our understanding about the mechanisms controlling the isotope variability in tree rings under different environmental conditions.

    Fate of carbohydrates and lignin in north-east Siberian permafrost soils
/ T. T. Dao [et al.] // Soil Biol. Biochem. - 2018. - Vol. 116. - P311-322, DOI 10.1016/j.soilbio.2017.10.032 . - ISSN 0038-0717
Аннотация: Permafrost soils preserve huge amounts of organic carbon (OC) prone to decomposition under changing climatic conditions. However, knowledge on the composition of soil organic matter (OM) and its transformation and vulnerability to decomposition in these soils is scarce. We determined neutral sugars and lignin-derived phenols, released by trifluoroacetic acid (TFA) and CuO oxidation, respectively, within plants and soil density fractions from the active layer and the upper permafrost layer at three different tundra types (shrubby grass, shrubby tussock, shrubby lichen) in the Northeast Siberian Arctic. The heavy fraction (HF; >1.6 g mL?1) was characterized by a larger enrichment of microbial sugars (hexoses vs. pentoses) and more pronounced lignin degradation (acids vs. aldehydes) as compared to the light fraction (LF; <1.6 g mL?1), showing the transformation from plant residue-dominated particulate OM to a largely microbial imprint in mineral-associated OM. In contrast to temperate and tropical soils, total neutral sugar contents and galactose plus mannose to arabinose plus xylose ratios (GM/AX) decreased in the HF with soil depth, which may indicate a process of effective recycling of microbial biomass rather than utilizing old plant materials. At the same time, lignin-derived phenols increased and the degree of oxidative decomposition of lignin decreased with soil depth, suggesting a selective preservation of lignin presumably due to anaerobiosis. As large parts of the plant-derived pentoses are incorporated in lignocelluloses and thereby protected against rapid decomposition, this might also explain the relative enrichment of pentoses with soil depth. Hence, our results show a relatively large contribution of plant-derived OM, particularly in the buried topsoil and subsoil, which is stabilized by the current soil environmental conditions but may become available to decomposers if permafrost degradation promotes soil drainage and improves the soil oxygen supply. © 2017

Аннотация: Salt-affected soils will become more frequent in the next decades as arid and semiarid ecosystems are predicted to expand as a result of climate change. Nevertheless, little is known about organic matter (OM) dynamics in these soils, though OM is crucial for soil fertility and represents an important carbon sink. We aimed at investigating OM dynamics along a salinity and sodicity gradient in the soils of the southwestern Siberian Kulunda steppe (Kastanozem, non-sodic Solonchak, Sodic Solonchak) by assessing the organic carbon (OC) stocks, the quantity and quality of particulate and mineral-associated OM in terms of non-cellulosic neutral sugar contents and carbon isotopes (delta C-13, C-14 activity), and the microbial community composition based on phospholipid fatty acid (PLFA) patterns. Aboveground biomass was measured as a proxy for plant growth and soil OC inputs. Our hypotheses were that (i) soil OC stocks decrease along the salinity gradient, (ii) the proportion and stability of particulate OM is larger in salt-affected Solonchaks compared to non-salt-affected Kastanozems, (iii) sodicity reduces the proportion and stability of mineral-associated OM, and (iv) the fungi : bacteria ratio is negatively correlated with salinity. Against our first hypothesis, OC stocks increased along the salinity gradient with the most pronounced differences between topsoils. In contrast to our second hypothesis, the proportion of particulate OM was unaffected by salinity, thereby accounting for only 10% in all three soil types, while mineral-associated OM contributed 90 %. Isotopic data (delta C-13, C-14 activity) and neutral sugars in the OM fractions indicated a comparable degree of OM transformation along the salinity gradient and that particulate OM was not more persistent under saline conditions. Our third hypothesis was also rejected, as Sodic Solonchaks contained more than twice as much mineral-bound OC than the Kastanozems, which we ascribe to the flocculation of OM and mineral components under higher ionic strength conditions. Contrary to the fourth hypothesis, the fungi : bacteria ratio in the topsoils remained fairly constant along the salinity gradient. A possible explanation for why our hypotheses were not affirmed is that soil moisture covaried with salinity along the transect, i.e., the Solonchaks were generally wetter than the Kastanozems. This might cause comparable water stress conditions for plants and microorganisms, either due to a low osmotic or a low matric potential and resulting in (i) similar plant growth and hence soil OC inputs along the transect, (ii) a comparable persistence of particulate OM, and (iii) unaffected fungi : bacteria ratios. We conclude that salt-affected soils contribute significantly to the OC storage in the semiarid soils of the Kulunda steppe, while most of the OC is associated with minerals and is therefore effectively sequestered in the long term.

Аннотация: Permafrost-affected soils in the northern circumpolar region store more than 1,000 Pg soil organic carbon (OC), and are strongly vulnerable to climatic warming. However, the extent to which changing soil environmental conditions with permafrost thaw affects different compounds of soil organic matter (OM) is poorly understood. Here, we assessed the fate of lignin and non-cellulosic carbohydrates in density fractionated soils (light fraction, LF vs. heavy fraction, HF) from three permafrost regions with decreasing continentality, expanding from east to west of northern Siberia (Cherskiy, Logata, Tazovskiy, respectively). In soils at the Tazovskiy site with thicker active layers, the LF showed smaller OC-normalized contents of lignin-derived phenols and plant-derived sugars and a decrease of these compounds with soil depth, while a constant or even increasing trend was observed in soils with shallower active layers (Cherskiy and Logata). Also in the HF, soils at the Tazovskiy site had smaller contents of OC-normalized lignin-derived phenols and plant-derived sugars along with more pronounced indicators of oxidative lignin decomposition and production of microbial-derived sugars. Active layer deepening, thus, likely favors the decomposition of lignin and plant-derived sugars, that is, lignocelluloses, by increasing water drainage and aeration. Our study suggests that climate-induced degradation of permafrost soils may promote carbon losses from lignin and associated polysaccharides by abolishing context-specific preservation mechanisms. However, relations of OC-based lignin-derived phenols and sugars in the HF with mineralogical properties suggest that future OM transformation and carbon losses will be modulated in addition by reactive soil minerals.
