Diversity of culturable endophytic fungi vary through time in Manihot esculenta Crantz

Braz. j. biol; 84 (), 2024
Abstract Endophytic fungi are a ubiquituos group that colonize all plant species on earth. Studies comparing the location of endophytic fungi within the leaves and the sampling time in Manihot esculenta Crantz (cassava) are limited. In this study, mature leaves of M. esculenta from Panama were collected ...

Providing inoculum for Didymella bryoniae studies: the effect of light spectrum and storing at low temperature

Braz. j. biol; 84 (), 2024
Abstract The in vitro sporulation of Didymella bryoniae is of great importance for studies that require pure inoculum and in large quantities. Thus, the objectives of this study were to identify the best condition for D. bryoniae sporulation combining different light spectra (UV-A or UV-B light, white li...

Microascus gracilis y otomicosis

Rev. chil. infectol; 40 (3), 2023
Microascus spp, teleomorfo de Scopulariopsis, es un hongo saprofito encontrado normalmente en suelo, alimentos, vegetales e incluso en ambientes interiores. Considerado un contaminante ambiental, se caracteriza por la resistencia intrínseca a los antifúngicos disponibles. Existen escasas referencias de...

Filtrates from cultures of endophytic fungi isolated from leaves of Copaifera oblongifolia (Fabaceae) affect germination and seedling development differently

Braz. j. biol; 83 (), 2023
Abstract Interactions between endophytic fungi (EFs) and their host plants range from positive to neutral to negative. The results of such interactions can vary depending on the organ of the infected host plant. EFs isolated from the leaves of some species of plants have potential for use as agents to in...

Endophytic Bacillus subtilis P10 from Prunus cerasifera as a biocontrol agent against tomato Verticillium wilt

Braz. j. biol; 83 (), 2023
Abstract Endophytic bacteria serve key roles in the maintenance of plant health and growth. Few studies to date, however, have explored the antagonistic and plant growth-promoting (PGP) properties of Prunus cerasifera endophytes. To that end, we isolated endophytic bacteria from P. cerasifera tissue samp...

Community structure of endophytic fungi in roots and leaves of Fagopyrum mill and Avena sativa in a Chinese northern cold region

Biosci. j. (Online); 39 (), 2023
In order to explore the endophytic fungi of Fagopyrum Mill and Avena sativa, Illumina Miseq high-throughput sequencing was used to analyze the community structure and diversity of endophytic fungi in leaves and roots of buckwheat and oat at the mature stage. The results of community structure showed that...

Ameliorative effects of morel mushroom (Morchella esculenta) against Cadmium-induced reproductive toxicity in adult male rats

Braz. j. biol; 82 (), 2022
Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (...

Chemical control of dieback and mango malformation in a semiarid region

The São Francisco Sub medium Valley is a great mango exporter in Brazil. In this semiarid region, diseases such as dieback and mango malformation have reduced the production of this crop. In this work the effectiveness of different active ingredients (flutriafol, methyl-thiophanate, copper hydroxide and...

New treatments to disinfect vine cuttings with Phaeomoniella chlamydospora and the reason for the control

Petri disease is a problem for vineyard caused mainly by the fungus Phaeomoniella chlamydospora. Contaminated seedlings are source of inoculum for the disease. Treatment to disinfect vine rootstock cuttings for seedling production is hot water treatment (HWT) by 50 °C for 30 min, but the efficiency is c...

Presence of hyphae in chromoblastomycosis examinations: an enigma to be solved

An. bras. dermatol; 96 (4), 2021
Abstract The detection of muriform cells in direct mycological or anatomopathological examination is considered pathognomonic for chromoblastomycosis. The morphological aspect that these fungal structures acquire were called "Borelli spiders", when associated with hyphae. Reports of this association have...
