1. Obtaining monokaryotic and dikaryotic mycelial cultures of two Amazonian strains of Geastrum (Geastraceae, Basidiomycota)
RESUMO A alta diversidade do gênero Geastrum e a dificuldade de obtenção de culturas miceliais prejudicam o estudo ecofisiológico e a exploração do potencial biotecnológico do táxon. Nesse estudo, foram testados diferentes meios de cultivo, visando a obtenção de culturas miceliais para G. lloydianum e G. subiculosum coletadas na Amazônia brasileir

2. Germination of spores of Amazonian ferns Polypodium aureum in different culture media
Resumo A maior diversidade de samambaias ocorre nos trópicos onde aproximadamente três quartos das espécies são encontradas. Na flora brasileira, as pteridófitas possuem uma megadiversidade, sendo importante grupo vegetal. O objetivo foi estudar a germinação dos esporos de samambaias Polypodium aureum em diferentes tipos de meio de cultura. Os esporâ

3. Compostos voláteis de fungos conidiais sapróbios da Amazônia Meridional no controle in vitro de fitopatógenos
RESUMO Estudos sobre compostos orgânicos voláteis (COVs) produzidos por fungos conidiais sapróbios da Amazônia (FCSA) ainda são inexistentes. Assim, verificou-se a produção de COVs de FCSA e, seu potencial no controle de fitopatógenos in vitro. Utilizou-se os FCSA Beltrania rhombica, Brachysporiella sp., Dictyochaeta sp., Gonytrichum sp. e avaliou-se

4. Interactions of adjuvants on adhesion and germination of Isaria fumosorosea on adults of Diaphorina citri
ABSTRACT: Asian citrus psyllid, Diaphorina citri, is considered the most important citrus pest worldwide, as it transmits Huanglongbing – serious citrus disease. New efficient and sustainable strategies to control this pest have been investigated and the use of entomopathogenic fungi has become a promising alternative. The objective of this study was to ev

5. Seed exudates of Sesbania virgata (Cav.) Pers. stimulate the asymbiotic phase of the arbuscular mycorrhizal fungus Gigaspora albida Becker & Hall
RESUMO Sesbania virgata é uma leguminosa utilizada na restauração de áreas degradadas e que forma simbiose com fungos micorrízicos arbusculares (AMF). Suas sementes exudam metabólitos secundários que podem influenciar a colonização pelos AMF. Neste trabalho, estudamos os efeitos de exsudatos de sementes (SE) e radiculares (RE) de S. virgata na fase

6. Spore germination and young gametophyte development of the endemic Brazilian hornwort Notothylas vitalii Udar & Singh (Notothyladaceae - Anthocerotophyta), with insights into sporeling evolution
ABSTRACT Notothylas vitalii is an endemic Brazilian hornwort species, easily identified by the absence of pseudoelaters and columella, and the presence of yellow spores. Plant material was collected in Recife, Brazil, and the spores were sown onto Knop’s medium, germinating after thirty days only with the presence of light. Germination occurred outside the

7. Abiotic environmental conditions for germination and development of gametophytes of Cyathea phalerata Mart. (Cyatheaceae)
ABSTRACT In order to successfully establish themselves in their natural environment, ferns need habitats with abiotic conditions that are suitable for spore germination and gametophyte development. The objective of this study was to assess the influence of abiotic factors on the initial development of Cyathea phalerata cultivated in vitro. Spore germination

8. Spore germination, early development and some notes on the effects of in vitro culture medium on Frullania ericoides (Nees) Mont. (Frullaniaceae, Marchantiophyta)
ABSTRACT In bryophytes, establishment can occur by a sexual or asexual process, but the production of spores enables colonization of a wider range of habitats and substrates than can asexual propagules. Successful germination is critical for establishment in a new environment. This paper addresses germination and sporeling development in Frullania ericoides,

9. Spore Germination and Protonemal Development of Dolichomitriopsis diversiformis
ABSTRACT Dolichomitriopsis diversiformis is an endemic and threatened moss in eastern Asia. In vitro culture and light microscopic observation were employed to study its developmental process from spore germination to the formation of young gametophyte, as well as effects of light and temperature on its spore germination and protonemal development. Microscop

10. Chemicals and lemon essential oil effect on Alicyclobacillus acidoterrestris viability
Alicyclobacillus acidoterrestris is considered to be one of the important target microorganisms in the quality control of acidic canned foods. There is an urgent need to develop a suitable method for inhibiting or controlling the germination and outgrowth of A.acidoterrestris in acidic drinks. The aim of this work was to evaluate the chemicals used in the le

11. Effects of temperature, salinity and irradiance on carposporeling development of Hidropuntia caudata (Gracilariales, Rhodophyta)
The success of seaweed cultivation depends on the scientific control of the tolerance limits and the optimal physiological conditions that affect the spore germination and the early development of algal species. In order to establish cultivation techniques for spores of Hidropuntia caudata (J. Agardh) Gurgel & Fredericq, the effects of irradiance, salinity,

12. Identificação e caracterização de genes que codificam proteínas secretadas por Hemileia vastatrix na interação com o cafeeiro / Identification and characterization of genes encoding proteins secreted by Hemileia vastatrix during interaction with coffee
The coffee leaf rust caused by the biotrophic fungus Hemileia vastatrix, it is the most important fungal disease of coffee, causing productivity losses and its control increases the costs of coffee production. This study aimed to identify genes of H. vastatrix that encode secreted proteins that may function as effectors needed for the establishment of the bi
