| insect deterrent and nematicidal screening of microfungi from mexico and anti-aphid compounds from gliomastix masseei. | fungal metabolites are promising alternatives for the development of biorational pesticides. in this sense, microfungi from tropical regions are valuable sources of natural compounds for pest management. with the aim of broadening the search for new eco-friendly products to manage plant pests, this study was carried out to evaluate the biological activity of 23 tropical fungal extracts on three species of phytophagous insects and a plant parasitic nematode. in addition, the active principles of ... | 2017 | 28258772 |
| dual effects of metarhizium spp. and clonostachys rosea against an insect and a seed-borne pathogen in wheat. | crops are often prone to both insect herbivory and disease, which necessitate multiple control measures. ideally, an efficacious biological control agent must adequately control the target organism and not be inhibited by other biological control agents when applied simultaneously. wheat seeds infected with the plant pathogen fusarium culmorum were treated with metarhizium brunneum or m. flavoviride and clonostachys rosea individually and in combination, with the expectation to control both root ... | 2016 | 25827357 |

| spore production of clonostachys rosea in a new solid-state fermentation reactor. | a new solid-state fermentation (ssf) reactor was developed for the spore production of biocontrol agent clonostachys rosea. the greatest spore production in the reactor, 3.36 × 10(10) spores g dm(-1) occurred with mixings, which was about 10 times greater than that in traditional tray reactor. the reactor provides about two times sporulation surface area for spore formation. moisture content of the medium was adjusted to meet the spore production by changing the surface porosity. two mixings wer ... | 2014 | 25267354 |
| colonization of onions by endophytic fungi and their impacts on the biology of thrips tabaci. | endophytic fungi, which live within host plant tissues without causing any visible symptom of infection, are important mutualists that mediate plant-herbivore interactions. thrips tabaci (lindeman) is one of the key pests of onion, allium cepa l., an economically important agricultural crop cultivated worldwide. however, information on endophyte colonization of onions, and their impacts on the biology of thrips feeding on them, is lacking. we tested the colonization of onion plants by selected f ... | 2014 | 25254657 |

| investigating the compatibility of the biocontrol agent clonostachys rosea ik726 with prodigiosin-producing serratia rubidaea s55 and phenazine-producing pseudomonas chlororaphis toza7. | this study was carried out to assess the compatibility of the biocontrol fungus clonostachys rosea ik726 with the phenazine-producing pseudomonas chlororaphis toza7 or with the prodigiosin-producing serratia rubidaea s55 against fusarium oxysporum f. sp. radicis-lycopersici. the pathogen was inhibited by both strains in vitro, whereas c. rosea displayed high tolerance to s. rubidaea but not to p. chlororaphis. we hypothesized that this could be attributed to the atp-binding cassette (abc) protei ... | 2016 | 26860841 |
| zearalenone lactonohydrolase activity in hypocreales and its evolutionary relationships within the epoxide hydrolase subset of a/b-hydrolases. | zearalenone is a mycotoxin produced by several species of fusarium genus, most notably fusarium graminearum and fusarium culmorum. this resorcylic acid lactone is one of the most important toxins causing serious animal and human diseases. for over two decades it has been known that the mycoparasitic fungus clonostachys rosea (synonym: gliocladium roseum, teleomorph: bionectria ochroleuca) can detoxify zearalenone, however no such attributes have been described within the trichoderma genus. | 2014 | 24708405 |
| biological control as a strategy to reduce the impact of mycotoxins in peanuts, grapes and cereals in argentina. | mycotoxins including aflatoxins, deoxynivalenol, fumonisins and ochratoxin a are among the main fungal secondary metabolites detected as natural contaminants in south america in different commodities such as peanuts (aflatoxins), cereals (deoxynivalenol and fumonisins) or grapes (ochratoxin a). different strategies including crop rotation, tillage practices, fungicide application and planting less susceptible cultivars are used in order to reduce the impact of these mycotoxins in both food and f ... | 2015 | 25427716 |
| interactions among filamentous fungi aspergillus niger, fusarium verticillioides and clonostachys rosea: fungal biomass, diversity of secreted metabolites and fumonisin production. | interactions among fungi colonizing dead organic matter involve exploitation competition and interference competition. major mechanism of interference competition is antibiosis caused by secreted secondary metabolites. the effect of competition on secondary metabolite production by fungi is however poorly understood. fungal biomass was rarely monitored in interaction studies; it is not known whether dominance in pairwise interactions follows congruent patterns. | 2016 | 27165654 |
| incidence and severity of leaf and fruit diseases of plums in latvia. | in the present study six plum orchards in latvia were examined during 2014. one orchard was commercial with integrated pest management (ipm) practices, one was with organic management, two orchards were scientific collections and in two orchards plums were grown as a minor crop, using ipm practices. the shot-hole disease (wilsonomyces carpophilus) and fruit rot were monitored in the field. samples of twigs and leaves were taken for further examination if some other disease symptoms were observed ... | 2015 | 27141740 |
| impact of uv-b radiation on clonostachys rosea germination and growth. | sensitivity to uv-b radiation is one of the main limitations of biological control of plant pathogens in the field. the effect of uv-b radiation on germination and leaf tissue colonization by the biological control agent clonostachys rosea was evaluated. there were variations among c. rosea strains in sensitivity to uv-b radiation. the most tolerant strain (lqc62) had relative germination of about 60 % after irradiation of 4.2 kj m(-2). the deleterious effects of uv-b radiation on c. rosea colon ... | 2012 | 22806155 |
| growth and asymmetry of soil microfungal colonies from "evolution canyon," lower nahal oren, mount carmel, israel. | fluctuating asymmetry is a contentious indicator of stress in populations of animals and plants. nevertheless, it is a measure of developmental noise, typically obtained by measuring asymmetry across an individual organism's left-right axis of symmetry. these individual, signed asymmetries are symmetrically distributed around a mean of zero. fluctuating asymmetry, however, has rarely been studied in microorganisms, and never in fungi. | 2012 | 22523554 |
| an atp-binding cassette pleiotropic drug transporter protein is required for xenobiotic tolerance and antagonism in the fungal biocontrol agent clonostachys rosea. | atp-binding cassette (abc) transporters mediate active efflux of natural and synthetic toxicants and are considered to be important for drug tolerance in microorganisms. in biological control agents (bca), abc transporters can play important roles in antagonism by providing protection against toxins derived from the fungal prey and by mediating the secretion of endogenous toxins. in the present study, we generated deletion and complementation strains of the abc transporter abcg5 in the fungal bc ... | 2014 | 24654977 |
| transcriptomic profiling to identify genes involved in fusarium mycotoxin deoxynivalenol and zearalenone tolerance in the mycoparasitic fungus clonostachys rosea. | clonostachys rosea strain ik726 is a mycoparasitic fungus capable of controlling mycotoxin-producing fusarium species, including f. graminearum and f. culmorum, known to produce zearalenone (zea) and deoxynivalenol (don). don is a type b trichothecene known to interfere with protein synthesis in eukaryotes. zea is a estrogenic-mimicing mycotoxin that exhibits antifungal growth. c. rosea produces the enzyme zearalenone hydrolase (zhd101), which degrades zea. however, the molecular basis of resist ... | 2014 | 24450745 |
