1. High rates of agricultural gypsum affect the arbuscular mycorrhiza fungal community and coffee yield
ABSTRACT High rates of agricultural gypsum, above the recommended levels, have been used on a regular basis to deepen plant roots and to alleviate recurrent water stress in Cerrado areas. However, very little is known about the consequences of this practice to arbuscular mycorrhizal fungi (AMF). Therefore, the objective of this study was to evaluate whether

2. Brazilian tropical dry forest (Caatinga) in the spotlight: an overview of species of Aspergillus, Penicillium and Talaromyces (Eurotiales) and the description of P. vascosobrinhous sp. nov.
ABSTRACT A literature-based checklist of species of Aspergillus, Penicillium, and Talaromyces recorded in the Brazilian tropical dry forest (Caatinga), the largest tropical dry forest region in South America, is provided. A total of 130 species (60 Aspergillus, 57 Penicillium, and 13 Talaromyces) are reported. Soil was the most common substrate, with 122 spe

3. Evaluation of Antifungal Potential of Leaf Extract of Chenopodium murale Against Fusarium oxysporum f. sp. lycopersici
RESUMO: O presente estudo foi realizado para avaliar a atividade antifúngica e a análise por CG-EM do extrato de folhas de Chenopodium murale contra Fusarium oxysporum f. sp. lycopersici (FOL), um patógeno de tomate altamente problemático no solo. Folhas secas de C. murale foram extraídas com metanol por duas semanas e, após a evaporação do solvente

4. Is arbuscular mycorrhizal fungal species community affected by cotton growth management systems in the Brazilian Cerrado?
Abstract: Conventional cotton production in western Bahia, Brazil, involves intensive use of agricultural inputs and mechanization, which may affect arbuscular mycorrhizal fungi (AMF). This work aimed at studying the impact of conventional and organic cotton production in the AMF of western Bahia. Soil samples were obtained from conventional white cotton and

5. Impact of agro-farming activities on microbial diversity of acidic red soils in a Camellia Oleifera Forest
ABSTRACT The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, r

6. Impacto da queima de vegetação do Cerrado sobre fungos habitantes do solo
Resumo Existem poucos estudos relacionados ao impacto de queimadas sobre os fungos habitantes do solo presente no cerrado. Objetivou-se com este trabalho identificar a micoflora presente em amostras de solos, antes e após o processo de queimada em duas profundidades, observando a interferência deste processo na população de fungos habitantes do solo. As

7. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

8. Identificação e seleção de espécies de Trichoderma spp. endofíticos de bromélias de restingas como agentes de biocontrole da fusariose em frutos de abacaxi
RESUMO Uma das doenças fúngicas de grande importância que ataca a cultura do abacaxizeiro é a fusariose, causado pelo fungo Fusarium guttiforme. A utilização do Trichoderma spp, que são fungos habitantes do solo e de ocorrência natural na forma endofítica em bromélias, ainda não foi estudada visando o biocontrole da gomose do abacaxizeiro. O traba

9. Micro-organismos endofíticos e níveis de nitrogênio no crescimento de plantas de arroz
RESUMO Os micro-organismos endofíticos podem estimular o crescimento a depender da interação com a planta hospedeira e da disponibilidade de nutrientes no solo. O objetivo deste trabalho foi avaliar o crescimento de plantas de arroz BRS Tropical cultivadas com fungos endofíticos e níveis de adubo nitrogenado em estufa agrícola. O delineamento experimen

10. Potential of aqueous extracts of basidiomycetes to control root-knot nematodes on lettuce
RESUMO Os nematoides das galhas (Meloidogyne incognita) estão entre as principais pragas da alface em função da elevada suscetibilidade da cultura, indisponibilidade de nematicidas e carência de cultivares resistentes. Foi objetivo deste trabalho, avaliar o potencial de extratos aquosos de dez diferentes basidiomicetos no controle de nematoides das galha

11. 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

12. Coccidioidomycosis: first cases reported in Pernambuco, Brazil
ABSTRACT Coccidioidomycosis is a fungal infection caused by Coccidioides immitis or Coccidioides posadasii. These fungi are known to thrive in desert climate. Fungi produce infectious arthroconidia in soil, they are aerosolized in the air and when inhaled by humans, usually cause infections such as pneumonia. The first cases of coccidioidomycosis in Brazil w
