Cavitation fatigue. Embolism and refilling cycles can weaken the cavitation resistance of xylem. (1/167)

Although cavitation and refilling cycles could be common in plants, it is unknown whether these cycles weaken the cavitation resistance of xylem. Stem or petiole segments were tested for cavitation resistance before and after a controlled cavitation-refilling cycle. Cavitation was induced by centrifugation, air drying of shoots, or soil drought. Except for droughted plants, material was not significantly water stressed prior to collection. Cavitation resistance was determined from "vulnerability curves" showing the percentage loss of conductivity versus xylem pressure. Two responses were observed. "Resilient" xylem (Acer negundo and Alnus incana stems) showed no change in cavitation resistance after a cavitation-refilling cycle. In contrast, "weakened" xylem (Populus angustifolia, P. tremuloides, Helianthus annuus stems, and Aesculus hippocastanum petioles) showed considerable reduction in cavitation resistance. Weakening was observed whether cavitation was induced by centrifugation, air dehydration, or soil drought. Observations from H. annuus showed that weakening was proportional to the embolism induced by stress. Air injection experiments indicated that the weakened response was a result of an increase in the leakiness of the vascular system to air seeding. The increased air permeability in weakened xylem could result from rupture or loosening of the cellulosic mesh of interconduit pit membranes during the water stress and cavitation treatment.  (+info)

Phenylcoumaran benzylic ether and isoflavonoid reductases are a new class of cross-reactive allergens in birch pollen, fruits and vegetables. (2/167)

We investigated the biochemical function of the birch pollen allergen Bet v 6 and its role in the IgE-cross-reactivity between birch pollen and plant foods, and characterized Pyr c 5, a Bet v 6-related food allergen, from pear; the proteins were expressed as His-Tag fusion proteins in Eschershia coli and purified by Ni-chelate affinity chromatography under native conditions. Nonfusion proteins were obtained by factor Xa protease treatment. The highest degree of amino-acid sequence identity of Pyr c 5 and Bet v 6 was found with a plant protein related to a defense mechanism, which we have named phenylcoumaran benzylic ether reductase (PCBER) based on its ability to catalyze the NADPH-dependent reduction of 8-5' linked lignans such as dehydrodiconiferyl alcohol to give isodihydrodehydrodiconiferyl alcohol. Enzymatic assays with recombinant Pyr c 5 and Bet v 6 showed PCBER catalytic activity for both recombinant allergens. Both Pyr c 5 and Bet v 6 allergens had similar IgE binding characteristics in immunoblotting and enzyme allergosorbent tests (EAST), and bound IgE from 10 sera of birch-pollen-allergic patients including six pear-allergic subjects. EAST inhibition experiments with Pyr c 5 as the solid phase antigen suggested that homologous allergens may be present in many vegetable foods such as apple, peach, orange, lychee fruit, strawberry, persimmon, zucchini (courgette), and carrot. In extracts of pear, apple, orange, and persimmon, the presence of proteins of approximately 30-35 kDa containing Bet v 6 cross-reactive epitopes was demonstrated with two Bet v 6-specific monoclonal antibodies. Recombinant Pyr c 5 triggered a strong, dose-dependent mediator release from basophils of a pear-allergic subject, suggesting that Pyr c 5 has the potential to elicit type I allergic reactions.  (+info)

Comparative analysis of pollen counts of Corylus, Alnus and Betula in Szczecin, Warsaw and Lublin (2000-2001). (3/167)

The aim of the study was to compare the airborne concentrations of allergenic pollen produced by three early flowering tree taxa (Corylus, Alnus, Betula) in the cities of Warsaw (central Poland), Lublin (eastern Poland) and Szczecin (western Poland) during the years 2000-2001. Measurements were performed by the volumetric method. Pollen seasons were defined as the periods in which 95% of the total catch occurred. The highest concentration and annual pollen count of Corylus was measured in Lublin in both seasons, while the highest annual pollen counts of Alnus and Betula were noted in Warsaw, where the annual pollen count of Betula in 2001 was four times higher than in 2000 and equalled 5,376 grains in m3 per 24 h. Significant differences in the pollen count of the examined taxa were observed between two seasons: the pollen count of Corylus was higher in 2000 than in 2001, while for Alnus and Betula the opposite was the case. The longest pollen seasons were observed at low annual pollen counts for the pollen of Corylus. Results of the study reveal significant differences between the seasons and the cities. The differences concern the dates of the appearance of pollen grains in the air, the duration of the presence of sporomorphs and the maximum concentrations in particular seasons. The pollen counts of alder, birch and hazel trees are determined by the weather, diversity of local flora and specific rhythm of pollination of particular taxa.  (+info)

Mast cell alpha-chymase reduces IgE recognition of birch pollen profilin by cleaving antibody-binding epitopes. (4/167)

In sensitized individuals birch pollen induces an allergic response characterized by IgE-dependent mast cell degranulation of mediators, such as alpha-chymase and other serine proteases. In birch and other plant pollens, a major allergen is profilin. In mammals, profilin homologues are found in an intracellular form bound to cytoskeletal or cytosolic proteins or in a secreted form that may initiate signal transduction. IgE specific to birch profilin also binds human profilin I. This cross-reactivity between airborne and endogenous proteins may help to sustain allergy symptoms. The current work demonstrates that cultured mast cells constitutively secrete profilin I, which is susceptible to degranulation-dependent proteolysis. Coincubation of chymase-rich BR mastocytoma cells with Ala-Ala-Pro-Phe-chloromethylketone (a chymase inhibitor) blocks profilin cleavage, which does not occur in degranulated HMC-1 mast cells, which are rich in tryptase, but chymase deficient. These data implicate chymase as the serine protease cleaving secreted mast cell profilin. Sequencing of chymase-cleaved profilins reveals hydrolysis at Tyr(6)-Val(7) and Trp(35)-Ala(36) in birch profilin and at Trp(32)-Ala(33) in human profilin, with all sites lying within IgE-reactive epitopes. IgE immunoblotting studies with sera from birch pollen-allergic individuals demonstrate that cleavage by chymase attenuates binding of birch profilin to IgE. Thus, destruction of IgE-binding epitopes by exocytosed chymase may limit further mast cell activation by this class of common plant allergens, thereby limiting the allergic responses in sensitized individuals.  (+info)

Morphological, cytogenetic, and molecular evidence for introgressive hybridization in birch. (5/167)

Extensive morphological variation of tetraploid birch (Betula pubescens) in Iceland is believed to be due to gene flow from diploid dwarf birch (B. nana) by means of introgressive hybridization. A combined morphological and cytogenetic approach was used to investigate this phenomenon in two geographically separated populations of natural birch woodland in Iceland. The results not only confirmed introgressive hybridization in birch, but also revealed bidirectional gene flow between the two species via triploid interspecific hybrids. The populations showed continuous morphological variation connecting the species, but karyotypically they consisted of only three types of plants: diploids, triploids, and tetraploids. No aneuploids were found. Some of the tetraploid plants had B. pubescens morphology as expected, but most of them had intermediate characters. Most of the diploid plants were B. nana, but some were intermediates and a few had B. pubescens morphology. The triploid plants were either intermediates or they resembled one of the two species. Similar introgressive variation was observed among the diploid and triploid progeny of open-pollinated B. nana in a garden. Birch samples including field plants and artificial hybrids were further examined using a molecular method based on genomic Southern hybridization. The experiments verified introgression at the DNA level.  (+info)

Leaf structural and photosynthetic characteristics, and biomass allocation to foliage in relation to foliar nitrogen content and tree size in three Betula species. (6/167)

Young trees 0.03-1.7 m high of three coexisting Betula species were investigated in four sites of varying soil fertility, but all in full daylight, to separate nutrient and plant size controls on leaf dry mass per unit area (MA), light-saturated foliar photosynthetic electron transport rate (J) and the fraction of plant biomass in foliage (F(L)). Because the site effect was generally non-significant in the analyses of variance with foliar nitrogen content per unit dry mass (N(M)) as a covariate, N(M) was used as an explaining variable of leaf structural and physiological characteristics. Average leaf area (S) and dry mass per leaf scaled positively with N(M) and total tree height (H) in all species. Leaf dry mass per unit area also increased with increasing H, but decreased with increasing N(M), whereas the effects were species-specific. Increases in plant size led to a lower and increases in N(M) to a greater FL and total plant foliar area per unit plant biomass (LAR). Thus, the self-shading probably increased with increasing N(M) and decreased with increasing H. Nevertheless, the whole-plant average M(A), as well as M(A) values of topmost fully exposed leaves, correlated with N(M) and H in a similar manner, indicating that scaling of MA with N(M) and H did not necessarily result from the modified degree of within-plant shading. The rate of photosynthetic electron transport per unit dry mass (J(M)) scaled positively with N(M), but decreased with increasing H and M(A). Thus, increases in M(A) with tree height and decreasing nitrogen content not only resulted in a lower plant foliar area (LAR = F(L)/M(A)), but also led to lower physiological activity of unit foliar biomass. The leaf parameters (J(M), N(M) and M(A)) varied threefold, but the whole-plant characteristic FL varied 20-fold and LAR 30-fold, indicating that the biomass allocation was more plastically adjusted to different plant internal nitrogen contents and to tree height than the foliar variables. Our results demonstrate that: (1) tree height and N(M) may independently control foliar structure and physiology, and have an even greater impact on biomass allocation; and (2) the modified within-plant light availabilities alone do not explain the observed patterns. Although there were interspecific differences with respect to the statistical significance of the relationships, all species generally fit common regressions. However, these differences were consistent, and suggested that more competitive species with inherently larger growth rates also more plastically respond to N and H.  (+info)

Hydrogen peroxide activates cell death and defense gene expression in birch. (7/167)

The function of hydrogen peroxide (H(2)O(2)) as a signal molecule regulating gene expression and cell death induced by external stresses was studied in birch (Betula pendula). Ozone (O(3)), Pseudomonas syringae pv syringae (Pss), and wounding all induced cell death of various extents in birch leaves. This was temporally preceded and closely accompanied by H(2)O(2) accumulation at, and especially surrounding, the lesion sites. O(3) and Pss, along with an artificial H(2)O(2) producing system glucose (Glc)/Glc oxidase, elicited elevated mRNA levels corresponding to genes encoding reactive oxygen species detoxifying enzymes, Pal, Ypr10, and mitochondrial phosphate translocator 1. In addition to the regulation of gene expression, Glc/Glc oxidase also induced endogenous H(2)O(2) production in birch leaves, accompanied by cell death that resembled O(3) and Pss damage. Wound-induced gene expression differed from that induced by O(3) and Pss. Thus, it appears that at least two separate defense pathways can be activated in birch leaves by stress factors, even though the early H(2)O(2) accumulation response is common among them all.  (+info)

Xylem ray parenchyma cells in boreal hardwood species respond to subfreezing temperatures by deep supercooling that is accompanied by incomplete desiccation. (8/167)

It has been accepted that xylem ray parenchyma cells (XRPCs) in hardwood species respond to subfreezing temperatures either by deep supercooling or by extracellular freezing. Present study by cryo-scanning electron microscopy examined the freezing responses of XRPCs in five boreal hardwoods: Salix sachalinensis Fr. Schmit, Populus sieboldii Miq., Betula platyphylla Sukat. var japonica Hara, Betula pubescens Ehrh., and red osier dogwood (Cornus sericea), in which XRPCs have been reported to respond by extracellular freezing. Cryo-scanning electron microscopy observations revealed that slow cooling of xylem to -80 degrees C resulted in intracellular freezing in the majority of XRPCs in S. sachalinensis, an indication that these XRPCs had been deep supercooled. In contrast, in the majority of XRPCs in P. sieboldii, B. platyphylla, B. pubescens, and red osier dogwood, slow cooling to -80 degrees C produced slight cytorrhysis without clear evidence of intracellular freezing, suggesting that these XRPCs might respond by extracellular freezing. In these XRPCs exhibited putative extracellular freezing; however, deep etching revealed the apparent formation of intracellular ice crystals in restricted local areas. To confirm the occurrence of intracellular freezing, we rewarmed these XRPCs after cooling and observed very large intracellular ice crystals as a result of the recrystallization. Thus, the XRPCs in all the boreal hardwoods that we examined responded by deep supercooling that was accompanied with incomplete desiccation. From these results, it seems possible that limitations to the deep-supercooling ability of XRPCs might be a limiting factor for adaptation of hardwoods to cold climates.  (+info)

The physiological mechanisms controlling plant responses to dynamic changes in ambient solar ultraviolet (UV) radiation are not fully understood: this information is important to further comprehend plant adaptation to their natural habitats. We used the fluorimeter Dualex to estimate in vivo the epidermal flavonoid contents by measuring epidermal UV absorbance (A375) in Betula pendula Roth (silver birch) leaves of different ages under altered UV. Seedlings were grown in a greenhouse for 15 days without UV and transferred outdoors under three UV treatments (UV‐0, UV‐A and UV‐A+B) created by three types of plastic film. After 7 and 13 days, Dualex measurements were taken at adaxial and abaxial epidermis of the first three leaves (L1, L2 and L3) of the seedlings. After 14 days, some of the seedlings were reciprocally swapped amongst the treatments to study the accumulation of epidermal flavonoids in the youngest unfolded leaves (L3) during leaf expansion under changing solar UV environments. ...
Three species of autoecious aphids, Callipterinella calliptera (Hartig), Euceraphis betulae (Koch), and Betulaphis brevipilosa Börner, commonly occur on European white birch trees, Betula pendula Roth, in northern California. Populations were sampled from 1981 through 1984 at two sites. Within-tree populations of all three species were more abundant in the lower and middle vertical thirds of tree canopies. Optimal sample sizes were estimated for individual trees as well as tree populations, given variable mean aphid densities, sampling reliability levels, and sampling costs. An aesthetic injury level for honeydew production was estimated. At both sites, all species exhibited spring and fall peaks with a summer decline in numbers. Callipterinella calliptera and B. brevipilosa populations increased during late summer while feeding on mature leaves. Euceraphis betulae preferred developing and senescing leaves and was reproductively

To elucidate the mechanisms underlying the population dynamics of Betula ermanii in response to climate change over temporal and spatial dimensions, 310 quadrats were systematically sampled in 7 plots located in the upper treeline region on the north-facing slopes of Changbai Mountains. IKONOS images were used to identify the spatial distribution of Betula ermanii with the aid of a digital elevation model (DEM). Meteorological data were recorded in the field throughout the study area and collected from a nearby long-term weather station, to reconstruct the temperature and precipitation changes. We collected tree-ring samples from a total of 1197 Betula ermanii trees. The correlation coefficients between 14 eco-climate parameters (from 1953 to 2008) and the aggregated annual indices of population dynamics for each quadrat (totaling 310 quadrats) in the corresponding years were calculated via statistical analysis facilitated by GIS technology. The results show that the Betula ermanii population is ...

Bud dynamic in mountain birch, Betula pubescens ssp. czerepanovii, is affected by biotic and abiotic factors such as temperature, light and herbivory. Climate probably has a large impact on module life history strategies i.e. survival, sexual and vegetative reproduction. (Modules are here defined as partially autonomous, repetitive and multicellular subunits within a tree.) Trade-off between present reproduction and future growth and/or reproduction occurs if resources are limiting. There is no direct trade-off between male catkin production and axillary bud production in mountain birch since male catkins are produced at the terminal bud of long-shoot. This bud is aborted when no catkin is present. However, same resources are used for both male catkin production and axillary bud production indicating that trade-offs occur in mountain birch. In my study I have simulated herbivory in order to study what effect trade-offs have on growth of long-shoot and bud performance.
Betula papyrifera trees were exposed to elevated concentrations of CO2 (1.4 x ambient), O3 (1.2 x ambient) or CO2 + O3 at the Aspen Free-air CO2 Enrichment Experiment. The treatment effects on leaf surface characteristics were studied after nine years of tree exposure. CO2 and O3 increased epidermal cell size and reduced epidermal cell density but leaf size was not altered. Stomatal density remained unaffected, but stomatal index increased under elevated CO2. Cuticular ridges and epicuticular wax crystallites were less evident under CO2 and CO2 + O3. The increase in amorphous deposits, particularly under CO2 + O3, was associated with the appearance of elongated plate crystallites in stomatal chambers. Increased proportions of alkyl esters resulted from increased esterification of fatty acids and alcohols under elevated CO2 + O3. The combination of elevated CO2 and O3 resulted in different responses than expected under exposure to CO2 or O3 alone. ...

In temperate climates there is a sudden movement of sap at the end of the winter as trees prepare to burst into growth. In North America, the sap of the sugar maple (Acer saccharum) is most often used in the production of a sweet liquid, maple syrup. About 90% of the sap is water, the remaining 10% being a mixture of various sugars and certain minerals. The sap is harvested by drilling holes in the trunks of the trees and collecting the liquid that flows out of the inserted spigots. It is piped to a sugarhouse where it is heated to concentrate it and improve its flavour. Similarly in northern Europe the spring rise in the sap of the silver birch (Betula pendula) is tapped and collected, either to be drunk fresh or fermented into an alcoholic drink. In Alaska, the sap of the sweet birch (Betula lenta) is made into a syrup with a sugar content of 67%. Sweet birch sap is more dilute than maple sap; a hundred litres are required to make one litre of birch syrup.[117] Various parts of trees are used ...

Birch polypore (Piptoporus betulinus) growing on the trunk of a silver birch tree (Betula pendula). This parasitic bracket fungus is found only on birch trees. The visible part of the fungus is the fruiting body that produces the spores, which are held in pores on the underside of the bracket. The fungus uses a fine mycelium network to extract nutrients from the trunk of the tree. It is generally only found on weakened trees, and the fungus can kill a birch tree over time. - Stock Image B250/1623

In a diversity of habitats, from lowland hardwoods, especially in the southern part of the state, to hemlock-white pine-northern hardwoods forest of the north, becoming especially common in the western Upper Peninsula. As is true of the other birches, the pistillate scales and bark of B. alleghaniensis are variable. Very old trees, as in virgin stands in the Upper Peninsula, may have very furrowed or checkered dark bark. Trees in swamps of the southern Lower Peninsula may have dark brown or blackish bark, which peels very little if at all; such trees hardly resemble the widespread typical yellow birch with light yellow-brown, peeling bark, and have sometimes been erroneously referred to B. lenta (which differs in having smaller, nearly or quite glabrous and less densely ciliate scales in the pistillate aments). Betula lenta and B. alleghaniensis both have a characteristic odor and flavor of wintergreen in the crushed bark of young twigs. Betula nigra, river birch, lacks the wintergreen flavor ...

Woschnagg, C.; Rak, S.; Venge, P., 1996: Oxygen radical production by blood eosinophils is reduced during birch pollen season in allergic patients
All patients were clinically diagnosed as birch pollen allergic. Seven patients allergic to birch pollen without any gastrointestinal symptoms and seven completely healthy individuals were included in the study for comparison. All patients were examined with a standard skin prick test panel and blood samples were analysed for IgE antibodies by component micro-arrays (ISAC). The two groups of patients underwent gastroscopy and duodenal biopsies were taken both during (May-June) and outside the pollen season (November-January) for each patient. Duodenal biopsies were examined with immunostaining for mast cells (IgE and tryptase), eosinophils (eosinophil peroxidase), T-cells (CD3), and dendritic cells (DC) (CD11c). ...
One example of a diagnostic application of recombinant birch allergens is found in a study examining allergen-specific serum IgE antibodies using the recombinant allergens Bet v 1, Bet v 2 and Bet v 4, as examined in birch-sensitive patients from the province of Cuneo, in northwestern Italy. It was reported that of 372 patients, 215 (58%) had serum IgE antibodies to Bet v 1, 166 (45%) to Bet v 2, and 35 (9%) to Bet v 4. Mono-sensitisation to Bet v 1 occurred in 146 (39%) of patients; in 96 (26%) to Bet v 2; and in only 4 (1%) to Bet v 4. Thirty-nine sera (11%) did not contain allergen-specific IgE antibodies to any of these three individual birch pollen allergens. All 372 sera (100%) had IgE antibodies against natural Birch pollen extract; 162 (44%) contained IgE antibodies reacting with Apple extract (75% of Bet v 1 positive sera). The study concluded that the 3 recombinant birch pollen allergens alone could identify 90% of birch pollen-sensitive patients (7 ...

inproceedings{41c8c41b-a2f5-4475-8be9-0341dfcd092f, abstract = {In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batatasin-III on photosynthesis by applying the compound (0.1, 1.0, or 2.8 mM) directly to the transpiration stream of intact Spinacia oleracea L. (spinach) and Betula pendula L. (birch) leaves. Within the concentration range used, batatasin-III had a small, but significant, effect on photosynthesis. The strongest effect was found on CO2 assimilation, but there were also significant effects on respiration and on maximum quantum yield of chlorophyll fluorescence (Fv / Fm). In spinach leaves treated with 2.8 mM of batatasin-III, a 14 % decrease in ...

White birch trees are popular ornamental trees because of their tall, graceful limbs and their beautiful pale bark. However, these trees are notoriously short-lived and tend to start declining after reaching about 40 or 50 feet in height. If you want to keep your white birch tree healthy, keep a close eye ...
Betula populifolia, commonly called gray birch, is a short-lived, narrow-columnar, suckering, deciduous tree that typically grows to 20-40 tall. It most often appears in a multi-trunked form, but also grows with a single trunk. It is native primarily from Southeastern Canada to Virginia, with a scattering of plants extending westward to Illinois. It typically occurs in both dry and wet soils. This tree is noted for (1) its non-peeling chalky white bark with dark chevron trunk patches appearing below each branch base and (2) its long-pointed triangular green leaves. Triangular leaves (each to 3 long) are double-toothed and shiny with tapered tips. Fall color is usually undistinguished. Tiny monoecious flowers appear in early spring in separate catkins on the same tree: yellowish-brown male flowers in single catkins (to 4 long) at the branch tips and greenish female flowers in smaller, upright catkins (to 1/2 long). Female flowers are followed by drooping cone-like fruits containing numerous ...

Aim: To test if there is an interactive effect between tree and understory species on the soil microbial community (SMC), community level physiological profiles (CLPP) and soil micro-fauna. Method: A replicate pot experiment with five sapling tree species (Betula pendula, Betula pubescens, Sorbus aucuparia, Quercus petraea and Pinus sylvestris) and a no-tree treatment with and without Calluna vulgaris was established. After 21 months samples were taken for phospholipid fatty acid (PLFA) analysis, CLPP and soil microfauna assessment. Results: There was an interactive effect of tree species and Calluna on the SMC, CLPP and nematode densities. Calluna addition changed the SMC composition (increase in fungal PLFAs) and the CLPP (lower utilisation of most carbon sources but greater utilisation of phenolic acids). A multivariate test for homogeneity of dispersion showed that while Calluna addition resulted in the presence of an altered microbial composition, it did not result in there being less ...
This research set on a former reclaimed opencast coal spoil in Varteg Hills, South Wales, UK explores the phytoremediation potential of Alnus glutinosa (Alder), Betula pendula (Roth) (Birch) and Larix decidua (Larch), which are commonly used in UK land reclamation, to sequester metals: Zn, Cd, Mn, Pb and Cu, from mine spoils. This study also compares the abilities of newly planted trees to sequester metals-on a new experimental site, within the landscape and compares these with those from older plantations on adjoining land. This chronosequence is used to evaluate the overall impact of forestation on metals levels in soils over two decades. Metal concentrations in soil were measured over three years and those in tree leaves were measured over two years. The majority of the samples examined lie between the UK defined thresholds for contamination but below levels that trigger immediate action and treatment. Samples within this range are placed within a new critical soil category. Mapping the ...
There are substantial levels of nucleotide polymorphisms in all five genes included in this study, both species-wide and within populations (Table 2). Levels of silent site diversity within populations averaged 0.0145, although diversity varied almost threefold between loci, from 0.0089 in GA20ox1 to 0.022 in TI-3. These values are comparable to within-population diversity in outcrossing A. lyrata (pW = 0.014, Wright et al. 2003) and to the average within-population diversity seen in Drosophila melanogaster (πW = 0.014, Moriyama and Powell 1996). It is also about two to fivefold higher than nucleotide polymorphism in the BpMADS2 gene in Betula pendula, another long-lived woody perennial, which was sampled from two locations in Finland (πW = 0.0047, Järvinen et al. 2002).. Species-wide levels of silent polymorphism in P. tremula (πsil = 0.016) are also comparable to levels of polymorphism in several plant species. In selfing A. thaliana, πsil = 0.0114, whereas in the two closely related, ...

Type I allergy is a major health problem in industrialized countries where up to 15% of the population suffer from allergic symptoms (rhinitis, conjunctivitis, and asthma). Previously, we identified a cDNA clone that encoded a birch pollen allergen as profilin. Profilins constitute a ubiquitous family of proteins that control actin polymerization in eukaryotic cells; in particular, profilin participates in the acrosomal reaction of animal sperm cells. Although profilins had been unknown in plants so far, our finding led to the assumption that profilins might have similar functions in pollens during plant fertilization and therefore represent allergenic components in almost all pollens. We show that profilins are prominent allergens that can be isolated from tree pollens (Betula verrucosa, birch), from pollens of grasses (Phleum pratense, timothy grass), and weeds (Artemisia vulgaris, mugwort). About 20% of all pollen allergic patients tested (n = 65) displayed immunoglobulin E (IgE) reactivity ...

American Dwarf Birch (Betula glandulosa) is a birch species native to North America, especially Greenland. It is also found in other cold temperate areas of the continent, such as Alaska, the higher attitudes of California, and the Black Hills of South Dakota. The shrub birch is multi-stemmed, rising to around 3 meters in height, and forms dense thickets. The trunks are smooth and slender with a dark brown bark. The leaves are circular or oval with toothed margins. The plant flowers in late springs. The flowers are monoecious. Preformed flowers appear at the end of the summer on the aments. When the female catkins get pollinated, they form small nutlets, and each nutlet has one seed. By early August seeds ripen and are ready for dispersal. The shrub also reproduces through vegetative propagation. A paper birch can regenerate from sprouts especially those of young trees cut in the spring. Vegetative reproduction is seldom but precious as a seed replacement during droughts and other difficult ...
We made a list of all the plants that we are currently growing in our container garden. Some of the plants we brought with us from our old garden. Included in these are a number of plants that we raised from seed. When growing plants from seed, each one is genetically distinct from the others. Although the majority will usually look quite similar when growing trees such as birch or alder, occasionally one can be pleasantly surprised. In 2006 we sowed seed of Betula albosinensis and an unusual alder, Alnus fruticosa. We potted up the germinated seeds and after a few years some plants were planted in the garden. From each of the two species, we got one individual amongst the seedlings which displayed characteristics remarkably different from the rest of their seedling batch; dwarf bushy plants! In the case of the Birch, after nine years our selected plant now measures less than 1 meter and has a bushy habit, all other plants grew much taller and average about 3 meters or more. From the alders only ...

River birch (Betula nigra) is a handsome tree native to the southeastern United States. It is considered the most widely adapted of all the birches, and hardy throughout South Carolina.
The allergen Bet v 1 is known as the primary sensitizer for birch pollen-related food allergy and is responsible for IgE cross-reactivity to pathogenesis-related 10 (PR-10) proteins from, in particular, fruits from the Rosaceae and vegetables from the Apiaceae families. The allergenic potential of PR-10 proteins is mainly characterized for specific recombinantly produced isoforms, which are used for research and diagnostic purposes. However, in natural food sources these allergens are often present as isoform mixtures. The first aim of this research was to purify and characterize PR-10 allergens as natural isoform mixtures to determine whether differences could be observed between natural and recombinant allergens and between plant families. The second aim was to find a relationship between the physico-chemical stability of PR-10 proteins and structural characteristics to explain differences in IgE binding potential and cross-reactivity. The PR-10 allergens Bet v 1 from birch, Api g 1 from ...

Dr Elaine Vickers, Research Relations Manager at Asthma UK, says: There are a few studies which suggest that the chemicals present in indoor swimming pools, like chlorine, may be involved in the development or worsening of asthma and other allergic conditions. This is due to the fact that the chemicals in the water may compromise protective cell barriers within the lungs, meaning people with allergic asthma are more vulnerable to allergens. However, asthma develops as a result of a complex mix of genetic and environmental factors, so more research is needed in this area before we can make a conclusive link between asthma and the use of chemicals in swimming pools. Swimming is an excellent form of exercise for children and young people with asthma as it can help improve lung capacity and the warm, humid air inside indoor pools is less likely to trigger asthma symptoms. We would therefore advise parents of children with asthma not to worry about letting their child go swimming, unless they ...

Plant-herbivore interactions are extremely variable, making it difficult to predict potential impacts on the surrounding ecosystem. Shrub proliferation and increased herbivore pressure through climate warming, particularly in the Northern Hemisphere, increases the potential for plant-herbivore dynamics to impact ecosystem function; yet no research has examined whether herbivore-plant dynamics can affect permafrost conditions. Thus, there is a need to better understand the impacts of these arthropods on the plants and their environment to predict future abiotic conditions. This study examined the effects of the gall-inducing Eriophyoid mite, Vasates oldfieldi, on Betula shrub physiology and associated energy inputs to the ground surface. Results from two consecutive field seasons indicate decreased thaw below galled shrubs driven by a compensatory response via shift in aboveground structure and increased transpirational water loss. These results suggest gall-inducing mites have the ability to ...

Sex differences in declarative memory and visuospacial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population based Betula study at two follow-up occasions.

Mr. Speaker, I will be splitting my time today with the member for Elgin-Middlesex-London.. I am very pleased to speak to the motion presented by member for London-Fanshawe. It goes without saying that we are disappointed by Caterpillars decision to close its Electro-Motive Diesel facility in London and by White Birch Paper Companys decision to close its idled Stadacona plant. I can tell members why from a very personal perspective.. I grew up in Cape Breton and unfortunately witnessed the closing of the coal mines, steel plant and the collapse of the fishery during the time when I was in high school there. I have great sympathy for the workers and their families affected by the decisions of these companies.. Unfortunately these events come at a time of global uncertainty. Because of that uncertainty, and as has already been pointed out, the government has taken significant steps toward helping manufacturing in our country.. Specifically, we have provided tax relief. We have enabled a 50% ...

The evidence was clear. The C-13 and C-14 was showing me that paper birch and Douglas fir were in a lively two-way conversation. It turns out at that time of the year, in the summer, that birch was sending more carbon to fir than fir was sending back to birch, especially when the fir was shaded. And then in later experiments, we found the opposite, that fir was sending more carbon to birch than birch was sending to fir, and this was because the fir was still growing while the birch was leafless. So it turns out the two species were interdependent, like yin and yang. ...
