| molecular identification of endophytic fungi isolated from needle leaves of conifers in bohyeon mountain, korea. | fungal endophytes are microfungi that live in plants without causing apparent symptoms of infection. this study was conducted to identify endophytic fungi isolated from leaves of coniferous trees in bohyeon mountain of korea. we collected leaves of two species of coniferous trees, pinus densiflora and pinus koraiensis, from 11 sites in the study area. a total 58 isolates were obtained and identified using molecular and morphological characteristics. four species of endophytic fungi were isolated ... | 2012 | 23323047 |
| effects of elevated co(2) and pb on the microbial community in the rhizosphere of pinus densiflora. | rising levels of atmospheric co(2) may stimulate forest productivity in the future, resulting in increased carbon storage in terrestrial ecosystems. however, heavy metal contamination may interfere with this, though the response is not yet known. in this study, we investigated the effect of elevated co(2) and pb contamination on microorganisms and decomposition in pine tree forest soil. three-year old pine trees (pinus densiflora) were planted in pb contaminated soils (500 mg/kg-soil) and uncont ... | 2012 | 23274974 |
| Mixotrophy of Platanthera minor, an orchid associated with ectomycorrhiza-forming Ceratobasidiaceae fungi. | • We investigated the fungal symbionts and carbon nutrition of a Japanese forest photosynthetic orchid, Platanthera minor, whose ecology suggests a mixotrophic syndrome, that is, a mycorrhizal association with ectomycorrhiza (ECM)-forming fungi and partial exploitation of fungal carbon. • We performed molecular identification of symbionts by PCR amplifications of the fungal ribosomal DNA on hyphal coils extracted from P. minor roots. We tested for a (13) C and (15) N enrichment characteristic of ... | 2012 | 21995447 |
| pathogenicity of aseptic bursaphelenchus xylophilus. | pine wilt is a disease of pine (pinus spp.) caused by the pine wood nematode (pwn), bursaphelenchus xylophilus. however, the pathogenic mechanism of pine wilt disease (pwd) remains unclear. although the pwn was thought to be the only pathogenic agent associated with this disease, a potential role for bacterial symbionts in the disease process was recently proposed. studies have indicated that aseptic pwns do not cause pwd in aseptic pine trees, while pwns associated with bacteria cause wilting s ... | 2012 | 22662271 |
| characterization and ph-dependent substrate specificity of alkalophilic xylanase from bacillus alcalophilus. | the gene of endo-beta-1-4 xylanase, xynt, was cloned from bacillus alcalophilus ax2000 and expressed in escherichia coli. this xynt, which belongs to glycoside hydrolase (gh) family 10, was found to have a molecular weight of approximately 37 kda and exhibit optimal activity at ph 7-9 and 50 °c. it exhibits a high activity towards birchwood xylan and has the ability to bind avicel. under optimal conditions, xynt hydrolyzes all xylooligomers into xylobiose as an end product with a preference for ... | 2012 | 22763748 |
| morphometric variation in pine wood nematodes, bursaphelenchus xylophilus and b. mucronatus, isolated from multiple locations in south korea. | intraspecific variation in morphometry of pine wood nematodes bursaphelenchus xylophilus and b. mucronatus in relation to geographical locations in south korea was investigated using morphometric characters (body length, a, b and c ratio, stylet length, and spicule length for a male nematode and v (%) value for a female nematode). b. xylophilus was isolated from pinus thunbergii in jinju (1998), ulsan (2000), yangsan (2000), mokpo (2001) and jeju (2004), and from p. densiflora in gumi (2001). b. ... | 2013 | 25288962 |
| host deception: predaceous fungus, esteya vermicola, entices pine wood nematode by mimicking the scent of pine tree for nutrient. | a nematophagous fungus, esteya vermicola, is recorded as the first endoparasitic fungus of pine wood nematode (pwn), bursaphelenchus xylophilus, in last century. e. vermicola exhibited high infectivity toward pwn in the laboratory conditions and conidia spraying of this fungus on japanese red pine, pinus densiflora, seedlings in the field protected the pine trees from pine wilt disease to some extent, indicating that it is a potential bio-control agent against pwn. previous research had demonstr ... | 2013 | 23990972 |
| laboratory and simulated field bioassays to evaluate larvicidal activity of pinus densiflora hydrodistillate, its constituents and structurally related compounds against aedes albopictus, aedes aegypti and culex pipiens pallens in relation to their inhibitory effects on acetylcholinesterase activity. | the toxicity of pinus densiflora (red pine) hydrodistillate, its 19 constituents and 28 structurally related compounds against early third-instar larvae of aedes albopictus (ae. albopictus), aedes aegypti (ae. aegypti) and culex pipiens palles (cx. p. pallens) was examined using direct-contact bioassays. the efficacy of active compounds was further evaluated in semi-field bioassays using field-collected larval cx. p. pallens. results were compared with those of two synthetic larvicides, temephos ... | 2013 | 26464387 |
| trichoderma songyi sp. nov., a new species associated with the pine mushroom (tricholoma matsutake). | a new species, trichoderma songyi, was found to be associated with the pine mushroom (tricholoma matsutake) in korea. this species was isolated from three different substrates: tricholoma matsutake basidiomata, as well as roots of pinus densiflora and soil in the fairy ring. based on its molecular and phenotypic characteristics, we demonstrate that trichoderma songyi is unique and distinguishable from closely related species. we performed phylogenetic analyses based on two molecular markers, the ... | 2014 | 25052534 |
