Pine wilt disease (PWD) caused by pine wood nematode (PWN), Bursaphelenchus xylophilus, is the most destructive diseases of pine and poses a threat of serious economic losses worldwide. Although several of the mechanisms involved in disease progression have been discovered, the molecular response of Pinus massoniana to PWN infection has not been explored. We constructed four subtractive suppression hybridization cDNA libraries by taking time-course samples from PWN-inoculated Masson pine trees. One-hundred forty-four significantly differentially expressed sequence tags (ESTs) were identified, and 124 high-quality sequences with transcriptional features were selected for gene ontology (GO) and individual gene analyses. There were marked differences in the types of transcripts, as well as in the timing and levels of transcript expression in the pine trees following PWN inoculation. Genes involved in signal transduction, transcription and translation and secondary metabolism were highly expressed after 24
The tree-killing mountain pine beetle (Dendroctonus ponderosae Hopkins) is an important disturbance agent of western North American forests and recent outbreaks have affected tens of millions of hectares of trees. Most western North American pines (Pinus spp.) are hosts and are successfully attacked by mountain pine beetles whereas a handful of pine species are not suitable hosts and are rarely attacked. How pioneering females locate host trees is not well understood, with prevailing theory involving random landings and/or visual cues. Here we show that female mountain pine beetles orient toward volatile organic compounds (VOCs) from host limber pine (Pinus flexilis James) and away from VOCs of nonhost Great Basin bristlecone pine (Pinus longaeva Bailey) in a Y-tube olfactometer. When presented with VOCs of both trees, females overwhelmingly choose limber pine over Great Basin bristlecone pine. Analysis of VOCs collected from co-occurring limber and Great Basin bristlecone pine trees revealed only a few
Maritime pine (Pinus pinaster Aiton) grows in a range of different climates in the southwestern Mediterranean region and the existence of a variety of latitudinal ecotypes or provenances is well established. In this study, we have conducted a deep analysis of the transcriptome in needles from two P. pinaster provenances, Leiria (Portugal) and Tamrabta (Morocco), which were grown in northern Spain under the same conditions. An oligonucleotide microarray (PINARRAY3) and RNA-Seq were used for whole-transcriptome analyses, and we found that 90.95 % of the data were concordant between the two platforms. Furthermore, the two methods identified very similar percentages of differentially expressed genes with values of 5.5 % for PINARRAY3 and 5.7 % for RNA-Seq. In total, 6,023 transcripts were shared and 88 differentially expressed genes overlapped in the two platforms. Among the differentially expressed genes, all transport related genes except aquaporins were expressed at higher levels in Tamrabta than in

Recent wildfires in mountain pine beetle (Dendrocronas ponderosae; MPB) post-outbreak lodgepole (pinus contorta var. latifolia) stands in the western United States have generated concern among stakeholders and disagreement over predicted fire behavior in the scientific literature. A study was conducted of wildland firefighters observations of fire behavior in beetle-killed lodgepole pine forests to garner a better understanding of expected vs. observed fire behavior, with a focus on what fire behaviors surprised firefighters. Twelve MPB post-outbreak wildfires and one prescribed fire were ...
The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia Roxb.), stone pine (P. pinea L.), eldar pine (P. eldarica Medv.) and mugo pine (P. mugo pumilio XENARI). The mugo pine and eldar pine species contained the highest (44.10%) and the lowest (37.40%) oil percentage, respectively. The eldar pine (12.45%) and the chir pine (12.23%) species contained the highest and the stone pine species (11.18%) contained the least rate of saturated fatty acids (SFA). Palmitic (6.33%) and oleic (36.29%) acids were the highest in the stone pine specie, and stearic acid (3.86%) was the highest in the chir pine specie. For human health, high levels of unsaturated fatty acids and little amount of saturated

The significant geographic extent of lodgepole pine (Pinus contorta) in the interior West and the large proportion within the mixed-severity fire regime has led to efforts for more ecologically based management of lodgepole pine. New research and demonstration activities are presented that may provide knowledge and techniques to manage lodgepole pine forests in the interior West. First, at the stand and watershed levels, a current application of a suite of restoration treatments to lodgepole pine stands within a watershed in central Montana is discussed. Second, a Bitterroot Ecosystem Management Research Project (BEMRP) study is presented that characterized landscape and patch dynamics in lodgepole pine forests at a coarser spatial resolution. Various landscape metrics for quantification of the range of variation in aerial extent of cover type and structural stage categories were used, and the implications for ecosystem management are discussed. ...
The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological consequences. This review explores the ramifications of the MPB epidemic with respect to mid-term timber supply, forest growth, structure and composition, vegetation diversity, forest fire, climate change, and ecosystem resilience. Research confirms that, in British Columbia, all of these variables are more significantly impacted when salvage logging is used as management response to the outbreak. We conclude that appropriate management in response to MPB is essential to ensuring ecologically resilient future forests and reliable mid-term timber supplies for affected human communities. We highlight knowledge gaps and avenues for research to advance our
Stone Pine cone with pine nuts - note two nuts under each cone scale. In Europe, pine nuts come from the Stone Pine (Pinus pinea), which has been cultivated for its nuts for over 6,000 years, and harvested from wild trees for far longer. The Swiss Pine (Pinus cembra) is also used to a very small extent.. In Asia, two species are widely harvested, Korean Pine (Pinus koraiensis) in northeast Asia (the most important species in international trade), and Chilgoza Pine (Pinus gerardiana) in the western Himalaya. Four other species, Siberian Pine (Pinus sibirica), Siberian Dwarf Pine (Pinus pumila), Chinese White Pine (Pinus armandii) and Lacebark Pine (Pinus bungeana), are also used to a lesser extent.. In North America, the main species are three of the pinyon pines, Colorado Pinyon (Pinus edulis), Single-leaf Pinyon (Pinus monophylla), and Mexican Pinyon (Pinus cembroides). The other eight pinyon species are used to a small extent, as are Gray Pine (Pinus sabineana), Torrey Pine (Pinus torreyana) ...

Regenerating longleaf pine by artificial means is an essential component of restoring the ecosystem across most of its range because there are limited acres of longleaf stands remaining. Establishing longleaf pine is an early step in the ecosystem restoration process. An overview discussion of artificial regeneration techniques and related issues are presented this paper. Other papers follow in the proceedings that provide more specific information related to reestablishing longleaf pine forests. ...
Pycnogenol, a standardized extract of French maritime pine bark, is composed of flavonoids, procyanidins, and phenolic acids. The mixture of the components has shown greater pharmacological effects than its purified components, such as cardiovascular benefits, antihypertensive effects, alleviation of allergies and asthma, reduction of thromboxane, and antidiabetic effects [18,20,32]. However, a recent study showed that the Korean red pine (P. densiflora) bark extract is also composed of flavonoids and phenolic acids, and has considerable antioxidant effects [33]. Several studies discovered antiadipogenic and anti-inflammatory effects of P. densiflora bark extract, but further studies are required to validate the effectiveness [34,35]. French maritime and Korean red pine bark extract have been studied in many diseases but rarely in ocular diseases. The role of pine bark extract in age-related cataract is still unclear. That being said, other antioxidant substances can be used to prevent oxidative ...
Pinus massoniaia Lamb has gained more and more attention as the most important tree species for timber and forestation in South China. Gene expression studies are of great importance to identify new and elite cultivars. Real-time quantitative PCR, a highly sensitive and specific method, is commonly used in the analysis of gene expression. The appropriate reference genes must be employed to normalize the calculation program for ascertaining repeatable and significant results. Herein, eleven housekeeping genes were evaluated during different stages of P. massoniana post nematode inoculation in this study. Three statistical approaches such as geNorm, NormFinder and BestKeeper were selected to analyze the stability of candidate genes. The results indicated that U2af and β-TUB were the most stable reference genes. These two genes could be used for the normalization in most of the experiments of P. massoniana, while Histone and AK were the least stable ones. In addition, EF expressed at the lowest average Ct
ABSTRACT During periods with epidemic mountain pine beetle ( Dendroctonus ponderosae Hopkins) populations in lodgepole pine ( Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests, large amounts of tree foliage are thought to undergo changes in moisture content and chemistry brought about by tree decline and death. However, many of the presumed changes have yet to be quantified. In this study, we quantified and compared fuel moisture, chemistry, and resulting flammability of bark beetle affected foliage in terms of ignitability, combustibility, consumability, and sustainability at a site in far eastern Idaho, USA. Results revealed substantial decreases in moisture content, the proportion of starches and sugars, and crude fat and increases in the proportions of lignin, cellulose, and hemicellulose in foliage of trees attacked in the previous year (yellow foliage) or more than two years previously (red foliage). Increases in emission rates of several terpenes that were correlated with
Pine trees are struck by a variety of diseases and pests depending on the location of the tree. One of the most common pine tree diseases is Canker disease. Canker disease leaves resin or dark, sticky patches all over the wood of the tree. This disease can be deadly to trees and spreads quickly. Needle cast is another commonly seen pine tree disease. Needle cast starts as dark spots on needles, which turn into reddish rings. The needles die from the ring to the tip. If needle cast is not stopped, the tree will slowly die. Blister rust is a fungus that attacks pine trees from gooseberry and currant bushes. The rust needs both plants to grow on the pine trees. Pine root rot is caused by a disease that attacks the roots of pine trees. The needles appear brown at the top of the tree, and the trees often fall down in high winds. Pine wilt is caused by a small beetle that attacks the trees by breeding and choking the plant. The trees turn brown and die.. ...

Some of the MCs obtained were characterized by viscosity average molecular weight, thermal behavior, ...
Pinus strobus grows approximately 1 m (3.3 ft) annually between the ages of 15 and 45 years, with slower height increments before and after that age range.[5] The tallest presently living specimens are 50-57.55 m (164 ft 1 in-188 ft 10 in) tall, as determined by the Native Tree Society (NTS).[6] Three locations in southeastern United States and one site in northeastern United States have trees that are 55 m (180 ft) tall. The southern Appalachian Mountains have the most locations and the tallest trees in the present range of Pinus strobus. One survivor is a specimen known as the Boogerman Pine in the Cataloochee Valley of Great Smoky Mountains National Park. At 57.55 m (188 ft 10 in) tall, it is the tallest accurately measured tree in North America east of the Rocky Mountains. It has been climbed and measured by tape drop by the Native Tree Society. Before Hurricane Opal broke its top in October 1995, Boogerman Pine was 63 m (207 ft) tall, as determined by Will Blozan and Robert Leverett using ...
The study compared the ability of seven bleaching agents to remove the blue colour from blue-stained lodgepole pine without adversely affecting the colour of unstained heartwood. A 10% solution of sodium hypochlorite was effective at removing the blue colour from blue-stained lodgepole pine sapwood. Sodium hypochlorite did not adversely affect the colour of heartwood, whereas three other bleaches initially caused a pronounced yellowing of heartwood, which faded over time.. ...

Pine trees have a lot more to offer other than being a festive centerpiece during holidays. Pine pollen has been considered a powerful superfood and medicine in Asia for more than 2,000 years. The pine product is widely-popular in China and Korea, as a potent longevity tonic that improves the bodys energy levels and boosts the immune system. In addition, Asian cultures consider pine pollen as a Jing-enhancing herb. Jing loosely translates to life force or essence. Plants labeled as Jing tonics are commonly used to treat weakness, stress-related burnout, exhaustion and various sexual imbalances such as low libido, infertility, and erectile dysfunction.. Pine pollen is known to contain powerful bio-available androgen phyto-hormones. These naturally-occurring phyto-hormones are found to be a lot safer compared with bio-identical hormones and prescription steroids. In addition, pine pollen does not interfere with normal negative feedback mechanism during hormone production. Pine pollen also ...
We have surveyed a chloroplast DNA restriction fragment length polymorphism in 745 individuals, distributed rangewide in eight allopatric natural populations of jack pine (Pinus banksiana Lamb.) and eight allopatric natural populations of lodgepole pine (Pinus contorta Dougl.). The polymorphic region of the chloroplast genome is located near duplicated psbA genes. Fourteen length variants were found in the survey, and these variants distinguished the two species qualitatively. Variant diversities were high in both species (hes = 0.43 in jack pine; hes = 0.44 in lodgepole pine). Population subdivision was weak within and among lodgepole pine subspecies and in jack pine (i.e., theta values were less than 0.05). This weak subdivision is compatible with theoretical predictions for paternally inherited markers in wind-pollinated outcrossers, as well as for polymorphisms with high length mutation rates. If these populations are at a drift-migration equilibrium, the chloroplast DNA restriction fragment ...
Fumigation of 2 year-old Aleppo pine (Pinus halepensis Mill.) trees with episodes of O3 (up to 120 nl l- as compared to 25 nl l-) throughout two summer seasons produces taller plants with greater stem diameters but reduced root:shoot ratios. Both light and electron microscopy of current year needles carried out at mid-summer reveal extensive accumulations of starch, particularly in the endodermis, and crushing of the phloem sieve cells. Parallel measurements of starch levels also reveal a non-mobilizable component. All these features probably indicate that episodes of high summer O3 detrimentally affect the normal ability of Aleppo pines to withstand severe water stress and this may account for their reduced vitality in Mediterranean regions. By autumn, however, the amounts of starch are similar to those in low O3-grown trees and no evidence of the phloem sieve tube crushing remain although plastids do show increased num bers of plastoglobull. Similar summer high level O3-fumigated needles also ...
A new University of Colorado Boulder study shows for the first time that episodes of reduced precipitation in the southern Rocky Mountains, especially during the 2001-02 drought, greatly accelerated development of the mountain pine beetle epidemic.

Georgia, in particular, there has been a strong effort toward restoration. Janisse Ray, in her elegant book of essays Ecology of a Cracker Childhood (2001), exposed many Georgians to the beauty and importance of the longleaf-grassland ecosystem. Several good examples of longleaf-grassland forest remain in the state. The military bases Fort Stewart and Fort Benning have the largest remaining blocks, while the Nature Conservancy controls several thousand acres, the Moody Tract in Appling County being its best holding of old-growth longleaf. In 2017, the state acquired the Sansavilla Wildlife Management Area, a nearly 17,000-acre stretch along the Altamaha River, with the aim of revitalizing its longleaf pine. Several high-quality stands also thrive on privately held lands, especially on some large quail plantations near Thomasville and Albany, including the Birdsong Nature Center and the Joseph W. Jones Ecological Research Center at Ichauway. Groups like the Longleaf Alliance, the Georgia Forestry ...
The heartwood from the pine tree, heart pine, is preferred by woodworkers and builders over the sapwood,[1] due to its strength, hardness and golden red coloration. The longleaf pine, the favored tree for heart pine, nearly went extinct due to logging. Before the 18th century, in the United States, longleaf pine forests, covered approximately 30-60 million acres along the coastal plain from Virginias southern tip to eastern Texas. These pine trees, 80 to 120 feet tall, require 100 to 150 years to become full size and can live up to 500 years. An inch of heart pine requires 30 years growth. Due to deforestation and over-harvesting since colonial days, only about 3% of the original Longleaf Pine forest remains.[2] The source of much of the available heart pine found on the market is longleaf pine from old buildings.[3] Before 1900 it was a source for poles, pilings, posts, sawlogs, flooring, plywood, pulpwood and naval stores (tapped for turpentine).[4] ...
Get this from a library! Modeling the effect of landscape pattern on mountain pine beetles. [Josie Hughes; Pacific Forestry Centre.;]
Its pliant branches gives it the common name limber and specific epithet flexilis. Its long needles are a dark, blueish green, its bark is heavily creased and dark grey. Its pale wood is lightweight and soft. Pinus flexilis is typically a high-elevation pine, often marking the tree line either on its own, or with whitebark pine (Pinus albicaulis), either of the bristlecone pines, or lodgepole pine (Pinus contorta). In favourable conditions, it makes a tree to 20 meters (65 ft), rarely 25 meters (80 ft) tall. However, on exposed treeline sites, mature trees are much smaller, reaching heights of only 5-10 meters (15-35 ft).[8] In steeply-sloping, rocky, and windswept terrain in the Rocky Mountains of southern Alberta, limber pine is even more stunted, occurring in old stands where mature trees are consistently less than 3 metres (10 ft) in height.[9] One of the worlds oldest living Limber Pine trees grows on the banks of the upper North Saskatchewan River at Whirlpool Point in Alberta. Recent ...
This study investigates the effects of seed dispersal through the European nutcracker (Nucifraga caryocatactes) on the genetic structure of Swiss stone pine (Pinus cembra). The corvid bird deposits several thousands of stone pine seeds annually in the soil as a future food resource. Since not all caches are recovered, this bird behaviour often leads to the establishment of Swiss stone pine seedlings. The combination of wind pollination with this bird-mediated seed dispersal can be expected to greatly shape the spatial distribution of genotypes and the genetic diversity within and among Swiss stone pine populations. Hence, the aim of this study was to investigate gene flow patterns, together with their effects on spatial genetic structure (SGS) and, thus, inbreeding probabilities in an exemplary P. cembra population. Furthermore, potential effects of inbreeding on offspring fitness were analysed, hypothesizing that rates of inbreeding and subsequent cumulative inbreeding depression are higher in ...

Pine pollen may be coating sidewalks and cars with yellow dust, but it is not to blame for making people sneeze. People suffer from pollen allergies, but pine pollen doesnt contribute to it. The chemical composition of pine pollen appears to make it less allergenic than other types. Because pine pollen is heavy, it tends to fall straight down, and does not scatter easily in the wind; therefore, it rarely reaches human noses.
The result of such changes is a decrease in the ability of the bronchi to cleanse dust and soot particles, which causes the progression of chronic bronchitis, respiratory failure, allergization of the body and an increase in the risk of developing oncological processes in the lungs.. Pine Pollen is the safest and most effective remedy to relieve you of any signs of illness. This drug has a powerful mucolytic effect, makes your breathing easier, relieves cough in the shortest possible time. Pine Pollen liquefies phlegm, thereby removing it from the body, quickly relieves shortness of breath, and also has an anti-inflammatory effect on the entire body. Thanks to Pine Pollen, you will get rid of the heat, regulate the work of the heart and completely forget about such a problem as cough.. In this article, you will learn about what is Pine Pollen, how it works, how to use capsules, what are their benefits, where to buy them in Singapore at a low price and how to order.

Pinus strobus, commonly called Eastern white pine, is a rapid-growing, long-lived, needled evergreen tree that is native to the northeastern United States and Canada (State tree of Maine and Michigan). Although pyramidal in its early years, it matures to a broad oval habit with an irregular crown. Typically grows 50-80 in cultivation, but will grow to 100 tall in the wild, with records existing to over 200. Landscape size and shape can be controlled through pruning, however, to the extent that white pine may be sheared and grown as a hedge.

Simultaneous hydrodistillation and extraction of Pinus cembra needles from Slovakia was done (via Likens Nickerson apparatus) for the first time. In essential oil extracts 55 compounds were identified, comprising 99.6% of the extract. The most abundant were monoterpene hydrocarbons (71.0%). In the terpene profile alpha-pinene, limonene/beta-phellandrene, germacrene D, beta-pinene, and delta-cadinene dominated (53.2%, 11.4%, 9.4%, 4.6%, and 4.3%, respectively). Seven new compounds for P. cembra, such as methyl daniellate (0.5%), 1,8 cineole (0.2%) and trans-cadina-1(6),4-diene (0.2%), etc. were found. In needle cuticular wax of P. cembra the amount of nonacosan-10-ol was 75.8%. n-Alkanes ranged from C-20 to C-35 with the most dominant C-31, C-29 and C-33 (33.4%, 16.9%, and 9.6%, resp.). Differences in terpene profiles between Slovakian and Greece from one side and Romanian and Polish cembran pines on the other side could be the consequence of its disjuncted areal in Carpathian Mountains caused by ...

Pine wilt disease (PWD) is a complex disease integrating three major agents: the pathogenic agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80s, the notion that another pathogenic agent, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unknown. The present work supports the possibility that some B. xylophilus-associated bacteria may play a significant role in the development of this disease. This is inferred as a consequence of: (i) the phenotypic characterization of a collection of 35 isolates of B. xylophilus-associated bacteria, in different tests broadly used to test plant pathogenic and plant growth promoting bacteria, and (ii) greenhouse experiments that infer the pathogenicity of these bacteria in maritime pine, Pinus pinaster. The results illustrate the presence of a heterogeneous microbial community associated with B. xylophilus and the

Winter mortality is a major factor regulating population size of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Glycerol is the major cryoprotectant in this freeze intolerant insect. We report findings from a gene expression study on an overwintering mountain pine beetle population over the course of 35 weeks. mRNA transcript levels suggest glycerol production in the mountain pine beetle occurs through glycogenolytic, gluconeogenic and potentially glyceroneogenic pathways, but not from metabolism of lipids. A two-week lag period between fall glycogen phosphorylase transcript and phosphoenolpyruvate carboxykinase transcript up-regulation suggests that gluconeogenesis serves as a secondary glycerol-production process, subsequent to exhaustion of the primary glycogenolytic source. These results provide a first look at the details of seasonal gene expression related to the production of glycerol in the mountain pine beetle.

N2 - Bursaphelenchus xylophilus (B. xylophilus) is a pine wood nematode that is known to cause pine wilt disease. We report here that B. xylophilus extracts augmented the polyclonal immunoglobulin E (IgE) production induced by lipopolysaccharide (LPS) plus interleukin-4 (IL-4) both in murine splenocytes and purified B cells as determined by ELISA and ELIspot assays, but they did not cause such a promotion in the absence of either LPS or IL-4. We also observed that the antigen-nonspecific IgE levels were increased in sera of mice treated with B. xylophilus extracts, which were comparable to those of Ascaris suum extracts. These findings suggest that administration of B. xylophilus ...
Abstract. The pine wood nematode, Bursaphelenchus xylophilus, is an invasive plant parasitic nematode and a worldwide quarantine pest. An indigenous species in North America and the causal agent of pine wilt disease, B. xylophilus has devastated pine production in Southeastern Asia including Japan, China, and Korea since its initial introduction in the early 1900s. The reactive oxygen species (ROS) is the first line of defense utilized by host plants against parasites, while nematodes, counteractively, employ antioxidants to facilitate their infection. Peroxiredoxins (Prxs) are a large class of antioxidants recently found in a wide variety of organisms. In this report, a gene encoding a novel 2-cysteine peroxiredoxin protein in B. xylophilus was cloned and characterized. The 2-cysteine peroxiredoxin in B. xylophilus (herein refers to as BxPrx) is highly conserved in comparison to 2-cysteine peroxiredoxins (Prx2s) in other nematodes, which have two conserved cysteine amino acids (Cp and Cr), a ...
The pine wood nematode (PWN), Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), is a major world-wide pathogen and pest of pine, with impacts on forest health, natural ecosystem stability and international trade. In Portugal, PWN was first diagnosed in 1999, the first occurrence also for Europe. The disease was recently detected on the island of Madeira and in northern Spain. In an attempt to search for more reliable and robust molecular markers that enable the study of intraspecific variability of B. xylophilus from different geographic locations, the intergenic spacer (IGS) region of the 5S rRNA gene and inter-simple sequence repeats (ISSR) analysis were used to determine the genetic relationships among 43 B. xylophilus isolates from Portugal, China, Japan, South Korea and USA. IGS sequence analysis showed that this region can only be used to establish interspecific relationships, since no differences were detected among Portuguese isolates from different geographic locations.

Abstract Title: Oral administration of French maritime pine bark extract (Flavangenol(®)) improves clinical symptoms in photoaged facial skin. Abstract: BACKGROUND: French maritime pine bark extract (PBE) has gained popularity as a dietary supplement in the treatment of various diseases due to its polyphenol-rich ingredients. Oligometric proanthocyanidins (OPCs), a class of bioflavonoid complexes, are enriched in French maritime PBE and have antioxidant and anti-inflammatory activity. Previous studies have suggested that French maritime PBE helps reduce ultraviolet radiation damage to the skin and may protect human facial skin from symptoms of photoaging. To evaluate the clinical efficacy of French maritime PBE in the improvement of photodamaged facial skin, we conducted a randomized trial of oral supplementation with PBE.METHODS: One hundred and twelve women with mild to moderate photoaging of the skin were randomized ...

Increased mortality of forest trees, driven directly or indirectly by climate change, is occurring around the world. In western North America, whitebark pine, a high elevation keystone species, and lodgepole pine, a widespread ecologically and economically important tree, have experienced extensive mortality in recent climate-driven outbreaks of the mountain pine beetle. However, even in stands experiencing high levels of mortality, some mature trees have survived. We hypothesized that the outbreak acted as a natural selection event, removing trees most susceptible to the beetle and least adapted to warmer drier conditions. If this was the case, genetic change would be expected at loci underlying beetle resistance. Given we did not know the basis for resistance, we used inter-simple sequence repeats to compare the genetic profiles of two sets of trees, survivors (mature, living trees) and general population (trees just under the diameter preferred by the beetles and expected to approximate the genetic
We sequenced and compared the genomes of the Dothideomycete fungal plant pathogens Cladosporium fulvum (Cfu) (syn. Passalora fulva) and Dothistroma septosporum (Dse) that are closely related phylogenetically, but have different lifestyles and hosts. Although both fungi grow extracellularly in close contact with host mesophyll cells, Cfu is a biotroph infecting tomato, while Dse is a hemibiotroph infecting pine. The genomes of these fungi have a similar set of genes (70% of gene content in both genomes are homologs), but differ significantly in size (Cfu ,61.1-Mb; Dse 31.2-Mb), which is mainly due to the difference in repeat content (47.2% in Cfu versus 3.2% in Dse). Recent adaptation to different lifestyles and hosts is suggested by diverged sets of genes. Cfu contains an alpha-tomatinase gene that we predict might be required for detoxification of tomatine, while this gene is absent in Dse. Many genes encoding secreted proteins are unique to each species and the repeat-rich areas in Cfu are ...
Amy Gannon, hatchet in hand, sliced a slab of bark from a lodgepole pine tree near Wolf Creek, Mont., and quickly spotted a mountain pine beetle larva no bigger than her pinky fingernail. This trees done for, said Gannon, an entomologist with the Montana Department of Natural Resources and Conservation. As wildfires roar through tinder-dry forests in California, the mountain pine beetle is silently killing even more trees -- hundreds of thousands of acres of towering trees, mostly lodgepole pine, according to Robert Mangold, director of Forest Health Protection for the U.S. Forest Service. An epidemic of this magnitude hasnt been seen in the Mountain West in 25 years, he said. In 2007, the beetles were blamed for killing 3.9 million acres of trees in Colorado, Montana, Wyoming, Oregon, Idaho, Utah and Washington, Mangold said. By comparison, the fires in California had burned 640,847 acres as of July 14 this year, according to the National Interagency Fire Center. An average of 3.4 million ...
Considered an EPPO A2 quarantine pest, Bursaphelenchus xylophilus is the causal agent of the pine wilt disease and the most devastating plant parasitic nematode attacking coniferous trees in the world. In the early stages of invasion, this nematode has to manage host defence mechanisms, such as strong oxidative stress. Only successful, virulent nematodes are able to tolerate the basal plant defences, and furthermore migrate and proliferate inside of the host tree. In this work, our main objective was to understand to what extent B. xylophilus catalases are involved in their tolerance to oxidative stress and virulence, using as oxidant agent the reactive oxygen species hydrogen peroxide (H2O2). After 24 hours of exposure, high virulence isolates of B. xylophilus could withstand higher H2O2 concentrations in comparison with low virulence B. xylophilus and B. mucronatus, corroborating our observation of Bxy-ctl-1 and Bxy-ctl-2 catalase up-regulation under the same experimental conditions. Both ...

Loblolly pine (Pinus taeda L.) is one of the most widely planted and commercially important forest tree species in the USA and worldwide. However, whole genome resequencing in loblolly pine is hampered by its size and complexity. Additionally, the genetics underlying quantitative traits of loblolly pine remains to be discovered. As a valid and more feasible alternative, entire exome sequencing was hence employed to identify the gene-associated single nucleotide polymorphisms (SNPs) and to genotype the 375 tress in a clonally tested loblolly pine population. Adaptive and growth traits were also measured and analyzed on this population. The exome capture efficiency was high. A total of 972,720 high quality SNPs were identified after filtering. We found that linkage disequilibrium (LD) decayed very rapidly within this population. Two main distinct clusters representing western and eastern parts of the loblolly pine range were demonstrated by the population structure analysis using unlinked SNPs. ...

Genetic differentiation in phenotypic traits among populations from heterogeneous environments is often observed in common-garden studies on forest trees, but data on adaptive variation in Scots pine (Pinus sylvestris L.) in Scotland are limited. As a result, current seed transfer guidelines are based on earlier molecular marker studies and do not take into account environmental or adaptive genetic variation. An analysis of spatial variation in climate showed substantial differences in temperature and precipitation among the native Scots pine sites in Scotland. To investigate whether differentiation in response to environmental variation has occurred in Scotland, a glasshouse-based common-garden trial of ~3,360 seedlings from 21 populations and 84 open-pollinated families was established in 2007. At the beginning of the 2nd growing season, timing of bud flush showed evidence of genetic differentiation among populations, with those from cooler origins generally flushing earlier. Variation was ...
Crude condensed tannins extracted from Pinus radiata bark (sourced from Tokoroa) with various solvents (Hot water (HW), methanol/water/acetic acid (MWA), acetone/water (AW) and hot aqueous 2% sulphite/urea solution (SFU)) were subjected to Sephadex LH-20 column chromatography to purify the condensed tannins by removing carbohydrate and flavonoid components (crude extracts were approximately 70% condensed tannins). The condensed tannins from the HW and MWA extractions were then fractionated on a Sephadex LH-20 column using a stepwise gradient of methanol, water and acetone to separate the condensed tannins according to molecular weight (MW). Fractions were collected and pooled to give eight final fractions (HW 1-8 and MWA 1-8). Purified and fractionated condensed tannin fractions were then analysed with a range of techniques including 1H nuclear magnetic resonance (NMR) spectroscopy, acid/phloroglucinol depolymerisation coupled with high performance liquid chromatography (HPLC) with UV and MS ...
Two species-specific PCR primer pairs were developed for identifying the two nematode species, Bursaphelenchus xylophilus and B. mucronatus. The primer pairs were developed from the sequence of ribosomal DNA (rDNA) repeats to produce DNA fragments of different lengths by PCR amplification. The DNA fragments for B. mucronatus and B. xylophilus were 210 bp and 557 bp, respectively. When mixed, neither primer pair inhibited the PCR amplification of the other. Five isolates of B. xylophilus and four isolates of B. mucronatus showed different band profiles of PCR products between the two species, but identical profiles among isolates of the same species.
Yes there are millions of acres of beetle killed pine trees in Colorado, but also Wyoming, Utah, Idaho, Montana, eastern Oregon and Washington, New Mexico, British Columbia, Alberta and the Yukon. Local politicians respond to local demands to do something, but rarely do they realize or at least tell their constituents that that beetle kill is unstoppable by humans. The pine trees over hundreds of thousands of square miles are vulnerable to attack due to their age, but more due to winters failure to have sustained cold temperatures below -20 F.. I have never seen a large pine bark beetle infestation stopped anywhere by human means. I have been following mountain pine beetle kills since 1974 when I was first hired as consultant on the Targhee National Forest to help with the big mountain pine bark beetle infestation there, west of Yellowstone Park. The current infestation is much large, it almost spans the Continent from north to south.. As far as the alledged fire danger of vast tracts of dead ...

The Japanese black pine (Pinus thunbergii) is highly susceptible to pine wilt disease caused by the pine wood nematode (PWN; Bursaphelenchus xylophilus). To cope with this disease, researchers and tree breeders selected PWN-resistant individuals in a previous breeding program. In an attempt to understand the mechanisms of resistance in the Japanese black pine, we created four LongSAGE (serial analysis of gene expression) libraries. A total of 20 818 tags were studied, including 5194 tags from a PWN inoculated resistant pine, 5218 a non-inoculated resistant pine, 5194 an inoculated non-resistant pine, and 5212 a non-inoculated non-resistant pine. The analysis of the libraries indicated that 14 tag species were significantly up-regulated (e.g., pathogenesis-related proteins 2 and 4, osmotin, lipoxygenase, and chalcone synthase), and nine were down-regulated (eukaryotic translation initiation factor SUI1, translationally controlled tumor protein, and xyloglucan endotransglycosylase) by the PWN ...
Molecular Phylogeny of Geographical Isolates of Bursaphelenchus xylophilus Implications on the Origin and Spread of this Species in China and Worldwide
Lawrence LeBlond for redOrbit.com - Your Universe Online. The next time you find yourself lost in the woods with no clean drinking water, the nearest pine tree may save your life. While lake or pond water may provide some short-term relief from dehydration when in the wild, these sources of water are not always clean.. This is where the pine tree comes into play. Pouring lake water through a freshly-peeled pine tree limb can effectively remove most bacteria that may exist in the water, leaving you with a clean and fresh source of H2O.. This process is so effective that MIT researchers, publishing a paper in the journal PLOS ONE on Feb. 26, found that the low-tech filtration system can produce up to four liters of clean drinking water per day.. The research team demonstrated that a small piece of sapwood can filter out 99 percent of E. coli bacteria from water. This sapwood, which contains xylem tissue that helps transport sap up through the tree, has pores that allow water to pass through but ...

to a new study by Dartmouth and U.S. Forest Service researchers. Winters have been warming across the western U.S. states for decades, as overall the coldest winter night has warmed by 4 degrees C since 1960. But that warming trend could only be the primary driver of increasing pine beetle outbreaks in regions where winter temperatures have historically killed most of the beetles, such as in the Middle Rockies, eastern Oregon, and northern Colorado, the study says. Warming is unlikely to have played a major role in other regions since winters were rarely cold enough to kill the beetles, according to the study published in the journal Landscape Ecology. Other factors - including changes in the pine beetles seasonal development patterns and forestry practices that have influenced pine density and age - were likely more important, the authors say ...

Polyamines are nitrogenous, growth regulator like compounds, which are present in all living organisms. In plants, polyamines affect, for example, cell division, differentiation and stress tolerance. The project is coordinated by Metla and funded by the Academy of Finland. In laboratory experiments the roots of young seedlings of Scots pine were inoculated with the mycelium of S. variegatus and the development of the mycorrhizal interaction and changes in polyamine concentrations were monitored for five weeks. In the presence of the mycorrhizal fungus, the gene essential for the formation of polyamines was activated in wide areas of the developing root vascular tissue of the young Scots pine seedlings. The results show that the fungus induces the synthesis of plant polyamines and that polyamines play an important role in the formation of the symbiosis between S. variegatus and Scots pine seedlings. Mycorrhizal fungi are able to produce different amounts of polyamines. The results encourage ...

Inventories are time- and money-consuming. Hence, accurate equations to estimate difficult-to-measure variables are desirable, especially for species that are not commercially established, such as Pinus lawsonii, P. leiophylla, P. pringlei and P. oocarpa. This study aimed to fit height and volume models for these species and to present stand attribute values for a plantation located in Guarei, Brazil, belonging to the company Resinas Brasil. Models were assessed by the adjusted coefficient of determination, mean square error and residual plots. For P. lawsonii and P. pringlei, the best hypsometric models were those of Van Soest and Mishailof, respectively. For P. leiophylla at 3 m × 1.5 m and 3 m × 3 m spacing, the best models were the linear and Mishailof models, respectively. For P. oocarpa planted at 3 m × 1.5 m and 3 m × 3 m spacing, the best models were those of Mishailof and Van Soest, respectively. The best volume model was the logarithmic Spurr for all species, except for P. oocarpa, where
Eastern white pine trees can live to be over 400 years old. Trees can grow up to a height of 53 metres and a diameter of 1.2 metres. White pine is monoecious, meaning that each individual tree possesses separated male and female reproductive structures. The seeds of white pine are located in cones, which mature over a two year period. Cone production begins at 5-10 years of age, but good seed years do not occur until the tree is over 20 years of age, and only every 3-5 years after that, although seeds are produced annually. The primary method of seed dispersal is by wind, which can send a seed traveling 60+ metres from the source within a stand of trees, and up to 220 metres in the open. However, animals also play a minor role in seed dispersal. Mice and voles create caches of white pine seeds just beneath the soil, and caches that are not revisited usually produce seedlings (Wilson & Gray, 2001 ...

They are contributing to the goal of the Americas Longleaf Initiative to bring back an ecosystem that once spanned from Virginia to Texas, and in North Carolina supports unique wildlife such as the Venus flytrap, which is considered at risk in the wild.
