1. Vanilla bahiana Hoehne (Orchidaceae): studies on fruit development and new perspectives into crop improvement for the Vanilla planifolia group
Resumo: Vanilla é o gênero mais bem conhecido e economicamente importante de Orchidaceae no mundo. A espécie Vanilla bahiana é restrita ao Brasil e seu estado de conservação foi recentemente avaliado como “Em Perigo”. A espécie é filogeneticamente próxima de V. planifolia, cujos frutos são a principal fonte natural de vanilina. As principais ca

2. Arbuscular mycorrhizal fungal communities in soils under three phytophysiognomies of the Brazilian Atlantic Forest
ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophy

3. The status of cryptococcosis in Latin America
Cryptococcosis is a life-threatening fungal infection caused by the encapsulated yeasts Cryptococcus neoformans and C. gattii, acquired from the environment. In Latin America, as occurring worldwide, C. neoformans causes more than 90% of the cases of cryptococcosis, affecting predominantly patients with HIV, while C. gattii generally affects otherwise health

4. Equilibrium and Out-Of-Equilibrium Investigation of Proton Exchange and CuII and ZnII Complexation on Fungal Mycelium (Trametes hirsuta)
This work presents potentiometric investigations of [mycelium/metal ion/water] complex systems and the development of a new model investigating the ion-mycelium-fluid interactions. Since pH is a major parameter in soil ecology exhibiting large fluctuations, we proposed an improved equilibrium and also out-of-equilibrium potentiometric titration method in ord

5. Superficial mycoses at the Hospital do Servidor Público Municipal de São Paulo between 2005 and 2011
BACKGROUND: Superficial mycoses are fungal infections limited to the outermost layers of the skin. Dermatophytic filamentous fungi and yeasts are the major causative agents of these mycoses. Dermatophytosis is one of the clinical conditions caused by fungal infections most commonly found in dermatological practice. Thus, knowledge of the ecology of dermato

6. Sweet orange scab with a new scab disease "syndrome" of citrus in the USA associated with Elsinoë australis
Elsinoë fawcettii causes citrus scab and E. australis causes sweet orange scab and there are different pathotypes of each species. Citrus scab is widely distributed, whereas sweet orange scab is limited mostly to southern South America. In 2010, E. australis was detected by PCR in Texas for the first time in the USA and subsequently found in commercial area

7. Microbial diversity in Brazilian mangrove sediments: a mini review
The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for B

8. Fungos endofíticos associados à Vellozia compacta Mart. ex Schult. F. (Velloziaceae) presente em afloramentos rochosos nos estados de Minas Gerais e Tocantins
The Vellozia compact Mart. ex Schult. &Schult. F. (Velloziaceae), popularly known as canela-de-ema, is a tropical monocot, endemic, common in quartzite formations and adapted to multiple biotic and abiotic stresses. Endophytic fungi are microorganisms that live inside the vegetal tissues, in spaces inter or intracellular, without causing any apparent damage

9. Arbuscular mycorrhizal fungi communities in soil and sugarcane roots / Comunidades de fungos micorrízicos arbusculares no solo e raízes de cana-de-açúcar
Arbuscular mycorrhizal fungi (AMF, Glomeromycota) form mutualistic symbioses with most land plants. AMF hypha generally grow through the soil and colonize the cortical tissue of the plant roots. However, it is not known whether the most abundant species in the soil, determined based on the morphology of asexual spores are the most abundant inside the roots,

10. Arbuscular mycorrhizal community in a permanent pasture and development of species-specific primers for detection and quantification of two AM fungi
Arbuscular mycorrhizal (AM) fungi are a group of symbionts that occupy different niches during their life cycle in roots and in the rhizosphere. They occur in soil as spores, hyphae and other propagules such as colonised root fragments. During the interaction with the plant roots a bidirectional transfer of mineral nutrients and carbon occurs, frequently ens

11. Natural 13C abundance reveals trophic status of fungi and host-origin of carbon in mycorrhizal fungi in mixed forests
Fungi play crucial roles in the biogeochemistry of terrestrial ecosystems, most notably as saprophytes decomposing organic matter and as mycorrhizal fungi enhancing plant nutrient uptake. However, a recurrent problem in fungal ecology is to establish the trophic status of species in the field. Our interpretations and conclusions are too often based on extrap

12. Ecology of Thermophilic Fungi in Mushroom Compost, with Emphasis on Scytalidium thermophilum and Growth Stimulation of Agaricus bisporus Mycelium
Twenty-two species of thermophilic fungi were isolated from mushroom compost. Scytalidium thermophilum was present in the compost ingredients, fresh straw, horse droppings, and drainage from compost and dominated the fungal biota of compost after preparation. Of 34 species of thermophilic fungi tested, 9 promoted mycelial growth of Agaricus bisporus on steri
