Summary • Investigating the dispersal of the root-pathogenic fungus Armillaria mellea is necessary to understand its population biology. AMP inhibits tumor proliferation and induces apoptosis in A549 cells. Positive correlations were found between total phenolic content in the extracts and antioxidant activity. hޜ�� Aims. The research was carried out in two independent experi-ments, with plants for each experiment propagated 2 months apart, and incubated in the same Conviron MTR30 growth chamber (Controlled Environments Limited, Winnipeg, Manitoba, … © 2015, Romanian Society for Pharmaceutical Sciences. The antioxidant properties of two wild edible mushroom species from the northeast of Portugal, Lactarius deliciosus (L.) Gray and Tricholoma portentosum (Fr.) Moribund stumps or roots provide a food source from which the fungus can spread to infected coffee. Armillaria mellea consists of at least ten reproductively isolated groups, the equivalent of “biological species.” Each biological species possesses bifactorial heterothallism with compatibility discernible by the gross mycelial morphology of paired monosporous isolates rather than the presence or absence of clamp connections and dikaryotic cells. Response of mycorrhizal grapevine to Armillaria mellea inoculation: disease development and polyamines The fruit body or mushroom, commonly known as stump mushroom, stumpie, honey mushroom, pipinky or pinky, grows typically on hardwoods but may be found around and on other living and dead wood or in open areas. Armillaria melleais the pathogen that causes root rot of many forest and ornamental and agronomic trees [1,2]. However, the effects of A. mellea on Alzheimer’s disease (AD) have not been systemically reported. 2011; Honey fungus. In both antioxidant assays, all lavender extracts showed significant and concentration-dependent activities. AMP-induced apoptosis occurred through the activation of caspase-3 and … Key words: Armillaria mellea, isolation by distance, microsatellite markers, spatial autocorrelation, spatial genetic structure, spore dispersal, wood decay fungi. Root Diseases and Soil-borne Pathogens, Berkeley, USA: University of California Press, 150-152 . Honey mushrooms (Armillaria mellea) are edible mushroom generally used in traditional oriental medicine. Armillaria mellea (Tricholomataceae) is a fungus symbiotic with the Chinese medicinal herb “Tianma” (Gastrodia elata Blume). The metals content was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Read our advice on honey fungus. Yet, no large-scale “-omics” data are available to enable new studies, and limited experimental models are available to investigate basidiomycete pathogenicity. Many conifers and hardwoods, and even some herbaceous plants, are susceptible. Armillaria mellea (Vahl) P. Kumm is a basidiomycete fungus in the genus Armillaria in the Physalacriaceae family which grows on the stumps and roots of a wide variety of woody and herbaceous plants. A polysaccharide (AMP) is isolated from the fruiting bodies of A. mellea.

Metal content and crude polysaccharide characterization of selected mushrooms growing in Romania. The ethanolic extract, having a total phenolic content of 11.47 ± 0.19 mg/g, showed a high 15-lipoxygenase inhibitory activity being only 3.5 times less active than (+)-catechin (EC50 = 226.67 ± 0.95 and 64.17 ± 0.15 μg/mL, respectively). microelements such as copper (varied from 15.8 mg/kg in A. mellea to 64.1 mg/kg in C. cibarius), iron (varied from 118 mg/kg in B. edulis to 221 mg/kg in A. mellea) and zinc (varied from 77.3 mg/kg in A. mellea to 188 mg/kg in C. cibarius). an der Hochschule für Angewandte Wissenschaften Hamburg Fakultät Life Science Studiengang Biotechnologie vorgelegt von Corinna Gebarowski Hamburg, 17. Fomes fomentarius sample contained the highest quantity of polyphenols (8.58 mg/g methanolic extract) and the sample 2 of Pleurotus ostreatus contained the highest quantity of flavonoids (2.62 mg/g methanolic extract). The ferrous ion chelating effect was superior to DPPH radical scavenging effect. The content of the components with antioxidant properties, such as total phenols, total flavonoids, β-carotene, lycopene and β-glucans were determined by spectrophotometric methods. Der Honiggelbe Hallimasch (Abb. : studies on substrate colonisation relating to the mechanism of biological control by ring-barking. Article/chapter can not be redistributed. Armillaria mellea is a common disease producing fungus found in much of California . 2007), and for other rootpathogens[e.g.,Thielaviopsisbasicola(Hood&Shew1996)]. The antioxidant activity of the detected polysaccharides was evaluated by means of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) scavenging and ferrous ion chelating assays. Coriander leaves showed stronger antioxidant activity than the seeds, and in both parts of coriander, the ethyl acetate extract contributed to the strongest activity. Armillaridin (AM) is an aromatic ester compound isolated from honey medicinal mushroom, Armillaria mellea, which has anti-cancer potential.

With conifers, killing of young, vigorous trees is fairly common, especially in plantations. tests: 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assay, 2,2’-azino-bis-3- ethylbenzthiazoline-6-sulphonic acid (ABTS) assay, iron chelating activity test and the capacity to block 15-lipoxygenase. Both two species showed antioxidant potential; but L. deliciosus proved to be more active. Swift MJ, 1970. Three different bioassays were used, namely scavenging of the diphenylpicrylhydrazyl (DPPH) radical method, inhibition of 15-lipoxygenase (15-LO) and inhibition of Fe2+ induced porcine brain phospholipid peroxidation. Older trees often get butt rot if they are infected rather than extensive killing of sapwood, cambium, and phloem. ]l�m�Uc�.����@3��/+%��3��Z�Ϥk„�Q�N����B���C���G:;K�"6�?�94t���}P��q1K�����A�sd�}P&>����vp6a\�gV؝X>���R��0#�W���T�`���UV{VXE��w��c+F��\ Uk��%|�$�/�G%*ʃp ����!��o�Иe��L�3�ěԲ$�#s�h���*t�=^��aҡ�-3{�"�t����@��T\>$j�d��I�W����j��o&�� �+�존��/�cF P��9����Qn�dq���g}|��>tq~�0�JF8�E���G�K0���|3n�!�4P���D�|��&ҏk �} ]n8t�}���'Z�K2�.����ȭ3o�|��0(rӔ�%#`-(Q. Total phenolic content was quantified as well. Munstead, there is no strict positive relationship between the polyphenolic content and antioxidant activity of extracts.
