1. Antifungal activity of selected plant extracts based on an ethnodirected study
ABSTRACT Plants have been reported as used by local populations to treat various infections for a long time, which has directed several pharmacological studies. The main aim of this work was to evaluate three plant selection criteria with better predictive power to detect extracts with antifungal action: (1) medicinal plants that are not used for indications

2. No fitness costs are induced by Spiroplasma infections of Aphis citricidus reared on two different host plants
Resumo Pulgões podem abrigar vários simbiontes secundários que alteram características ecológicas importantes, como defesa contra inimigos naturais, tolerância ao calor e utilização da planta hospedeira. Um desses simbiontes secundários, Spiroplasma, é estudado em Drosophila por alterar a razão sexual e interagir com o sistema imunológico do hosp

3. DIVERSITY OF ARBUSCULAR MYCORRHIZAL FUNGI IN FOREST ECOSYSTEMS OF BRAZIL: A REVIEW
ABSTRACT Plants can stablish symbiosis with arburcular mycorrhiza fungi (AMF), in which the fungus uses carbohydrates synthesized by plant photosynthesis in exchange for soil nutrients. AMF symbiosis may benefit plants by increasing the rates of nutrient uptake, tolerance to abiotic stresses, protection against pathogens and, by promoting resilience of fores

4. The Antifungal Activity of Naphthoquinones: An Integrative Review
ABSTRACT Naphthoquinones are the most commonly occurring type of quinones in nature. They are a diverse family of secondary metabolites that occur naturally in plants, lichens and various microorganisms. This subgroup is constantly being expanded through the discovery of new natural products and by the synthesis of new compounds via innovative techniques. In

5. Selection, isolation, and identification of fungi for bioherbicide production
Abstract Production of a bioherbicide for biological control of weeds requires a series of steps, from selection of a suitable microbial strain to final formulation. Thus, this study aimed to select fungi for production of secondary metabolites with herbicidal activity using biological resources of the Brazilian Pampa biome. Phytopathogenic fungi were isolat

6. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco

7. Activity of Fabaceae species extracts against fungi and Leishmania: vatacarpan as a novel potent anti-Candida agent
AbstractLeishmaniasis and fungal infection treatment efficacy is limited by toxicity and ever increasing resistance to available drugs, requiring development of alternative compounds. The richness of Cerrado plant antimicrobial secondary metabolites justifies screening of Fabaceae species extracts: Enterolobium ellipticum Benth., Sclerolobium aureum (Tul.) B

8. TRIAGEM METABÓLICA POR PKS E NRPS EM ACTINOBACTÉRIAS ENDOFÍTICAS DE Citrus reticulata
Polyketides and non-ribosomal peptides are natural products widely found in bacteria, fungi and plants. The biological activities associated with these metabolites have attracted special attention in biopharmaceutical studies. Polyketide synthases act similarly to fatty acids synthetases and the whole multi-enzymatic set coordinating precursor and extending

9. Phylogeny and molecular dating of the cerato-platanin-encoding genes
The cerato-platanin family consists of proteins that can induce immune responses, cause necrosis, change chemotaxis and locomotion and may be related to the growth and development of various fungi. In this work, we analyzed the phylogenetic relationships among genes encoding members of the cerato-platanin family and computed the divergence times of the genes

10. Oral treatments for fungal infections of the skin of the foot
BACKGROUND: About 15% of the world population have fungal infections of the feet (tinea pedis or athlete's foot). There are many clinical presentations of tinea pedis, and most commonly, tinea pedis is seen between the toes (interdigital) and on the soles, heels, and sides of the foot (plantar). Plantar tinea pedis is known as moccasin foot. Once acquired,

11. Caracterização da diversidade de fungos filamentosos associados a esponjas marinhas e avaliação da produção de lacase = : Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production / Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production
The ocean represents a promissing habitat in the search for new microorganisms, which may have the ability to produce enzymes of industrial interests different from that produced by their terrestrial counterparts. In this context, two samples of the marine sponge Dragmacidon reticulatum were collected on northern coast of São Paulo State, aiming at the char

12. Produção de celulases, purificação e caracterização bioquímico-cinética da β-galactosidase produzida por fungo isolado da região amazônica / Production of cellulases, purification and characterization of kinetic biochemical ß-galactosidase produced by fungus isolated from the Amazon.
The selection of cellulase-producing fungi is one of the possible estrategies for obtaining necessary enzymes to hydrolyze the lignocellulosic material of plant biomass and thereby contribute to the viability of cellulosic ethanol production. The aim of this study was achive a screening of isolated fungi from the Amazon region to assess the production of enz
