Genetic variability and vegetative compatibility of Erythricium salmonicolor isolates
Provedor de dados: 63
Autores: Sebastianes,Fernanda Luiza de Souza; Maki,Cristina Sayuri; Andreote,Fernando Dini; Araújo,Welington Luiz; Pizzirani-Kleiner,Aline Aparecida.
The Pink Disease is caused by Erythricium salmonicolor, which attacks broad hosts, such as citrus, coffee, rubber, Eucalyptus spp. and Acacia spp., infecting mainly branches. This disease became a serious problem in Brazil, reducing the citrus production up to 10%. However the genetic diversity and compatibility of the fungus E. salmonicolor from Brazilian citrus plants is not yet evaluated. Therefore, the aims of this study were to evaluate: i) the genetic variability of E. salmonicolor in the São Paulo and Minas Gerais States by the RAPD technique, and ii) the vegetative compatibility between these isolates. After RAPD analysis, six distinct groups were observed without correlation between the isolation site or host species. In the vegetative...

Daldinia eschscholtzii (Ascomycota, Xylariaceae) isolated from the Brazilian Amazon: taxonomic features and mycelial growth conditions
Provedor de dados: 36

The Amazon has a high diversity of fungi, including species of the genus Daldinia (Ascomycota, Xylariaceae), which produce secondary metabolites with recognized nematicidal and antimicrobial activity. The ecological role of Daldinia is important, as stromata serve as refuges to many insects and arthropodes, and the fungi contribute to the degradation of vegetable organic matter. The aim of this study was to analyze the taxonomic features and mycelial growth conditions in vitro of a Daldinia specimen collected in the Brazilian Amazon. Morphological and molecular studies of the fungus identified it as D. eschscholtzii. To evaluate mycelial growth, we cultivated the fungus at 20, 25, 30, 35, and 40 °C in malt extract-peptone agar (MEPA), malt extract-peptone...

ANTAGONISTIC EFFECT OF EDIBLE MUSHROOM EXTRACT ON CANDIDA ALBICANS GROWTH
Provedor de dados: 58
Autores: Paccola,Edneia A. de Souza; Maki,Cristina Sayuri; Nobrega,Gisele M.A. de; Paccola-Meirelles,Luzia Doretto.
Five species of edible mushrooms, Lentinula edodes, Pleurotus ostreatus, Pholiota nameko, Macrolepiota bonaerensis and Agaricus blazei, were tested for their potential to inhibit the in vitro growth of the pathogenic yeast Candida albicans. Only L. edodes had a fungistatic effect on this human pathogen. The inhibitory compound was produced intra and extracellularly in submersed L. edodes culture, and was also present in fresh and dehydrated mushroom basidiocarps. The fungistatic compound was heat sensitive and lost activity after 72 hours.

ANALYSES OF GENETIC VARIABILITY IN LENTINULA EDODES THROUGH MYCELIA RESPONSES TO DIFFERENT ABIOTIC CONDITIONS AND RAPD MOLECULAR MARKERS
Provedor de dados: 58
Autores: Maki,Cristina Sayuri; Teixeira,Flavia França; Paiva,Edilson; Paccola-Meirelles,Luzia Doretto.
The growth of thirty-four Lentinula edodes strains submitted to different mycelial cultivation conditions (pH and temperature) was evaluated and strain variability was assessed by RAPD molecular markers. The growth at three pH values (5, 6 and 7) and four different temperatures (16, 25, 28 and 37ºC) was measured using the in vitro mycelial development rate and water retention as parameters. Mycelial cultivation was successful at all pH tested, while the ideal temperature for mycelial cultivation ranged between 25 and 28ºC. The water content was lower in strains grown at 37ºC. Among 20 OPA primers (Operon Technologies, Inc.) used for the RAPD analyses, seventeen presented good polymorphism (OPA01 to OPA05, OPA07 to OPA14, OPA17 to OPA20). The clustering...
