1. Semi-automated counting model for arbuscular mycorrhizal fungi spores using the Circle Hough Transform and an artificial neural network
Abstract: Arbuscular Mycorrhizae (AM) are mutualistic associations between Arbuscular Mycorrhizal Fungi (AMF) and the roots of many plant species. AMF spores give rise to filaments that develop in the root system of plants and contribute to the absorption of water and some nutrients. This article introduces a semi-automated counting model of AMF spores in sl

2. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

3. Arbuscular mycorrhizal fungal communities in the rhizosphere of a continuous cropping soybean system at the seedling stage
Abstract Arbuscular mycorrhizae (AM) fungi play a crucial role in the growth of soybean; however, the planting system employed is thought to have an effect on AM fungal communities in the rhizosphere. This study was performed to explore the influence of continuous soybean cropping on the diversity of Arbuscular mycorrhizal (AM) fungi, and to identify the dom

4. Arbuscular mycorrhizal fungi and dark septate fungi in plants associated with aquatic environments
ABSTRACT There have been several reports of symbionts in the roots of plants that live in aquatic environments. Arbuscular mycorrhizal fungi (AMF) are the most common microsymbionts and possibly recolonized the aquatic environment together with plants; however, their functions and the extent of their benefits are unclear. Furthermore, the presence of other g

7. Contribuição da micorriza arbuscular na resposta das culturas à calagem e adubação fosfatada em solos de cerrado.
ABSTRACT: The crop production in the cerrado soils may be improved when high amounts of lime and phosphate fertilizers are used. An economical management alternative of these inputs involves biological processes as the arbuscular mycorrhiza. The presence of arbuscular mycorrhizal fungi in the soil and the consequent root colonization cause an alteration in t

8. Manejo da micorriza arbuscular em sistemas integrados de lavoura e pastagens no Cerrado.
ABSTRACT: The arbuscular mycorrhizal fungi community is low in Cerrado soils and it gradually increases with soil cropping. Rotations of crops and of production systems stimulate propagation of those fungi in the soil, mycorrhiza formation and its effects in the plants. The crop-pasture integrated systems are well recommended, as pastures favors spores multi

9. Importância da micorriza arbuscular para o cultivo da mandioca na região do cerrado.
ABSTRACT: Cassava plants are highly dependent on arbuscular mycorrhiza for its optimum growth. Its cultivation in cerrado soil requires soil and culture management as soil liming and fertilization and crop rotation. Though, higher plant growth and root yield are attained and applied inputs are better usen when the cassava plants are mycorrhizal. The adequate

10. Ocorrencia de micorrizas arbusculares e da bacteria diazotrofica acetobacter diazotrophicus em cana-de-acucar.
Foi avaliada a ocorrencia e a distribuicao de especies de fungos micorrizicos arbusculares (FMAs) e Acetobacter diazotrophicus em plantios de cana-de-acucar em diferentes tipos de manejo nos Estados do Rio de Janeiro e Pernambuco. Foram feitas 35 coletas de amostras de solo da rizosfera e de raizes de 14 variedades de cana-de-acucar para extracao de esporos

11. Atividade de flavonoides sobre esporos do fungo micorrizico Giaspora gigantea in vitro.
Os flavonoides vegetais, alem de atuarem em diversos processos do crescimento e desenvolvimento das plantas, soa bastante ativos na relacao planta-microrganismos. Na simbiose rizobio-leguminosas, por exemplo, eles atuam como sinais moleculares ativando a transcricao de genes essenciais na interacao bacteria-planta. Apesar da acao estimulante de alguns flavon

12. Desenvolvimento de micorrizas arbusculares em mutantes hormonais de tomateiro (Lycopersicon esculentum cv Micro-Tom) / Development of arbuscular mycorrhiza in hormonal mutants of tomato (Lycopersicon esculentum cv Micro-Tom)
Os hormônios vegetais etileno e ABA são possíveis reguladores chave do desenvolvimento das micorrizas arbusculares (MAs). O primeiro objetivo deste trabalho foi avaliar o desenvolvimento da MA em mutantes superprodutores e insensíveis ao etileno (epinastic e Never ripe, respectivamente) e verificar se enzimas relacionadas ao sistema de defesa vegetal sã
