1. Urochloa decumbens Has Higher Mycorrhizal Colonization in Degraded than in Pristine Areas in the Brazilian Cerrado
ABSTRACT Brazil has extensive degraded areas, where vegetation fails to establish due to harsh soil conditions. However, some invasive species such as Urochloa decumbens are successful pioneers in such areas, but the reasons deserve investigation. Mycorrhizal fungi are abundant in Cerrado soils, and their association with plants are beneficial for their esta

2. Establishment of Leguminous Trees in the Soil of a Shooting Range
ABSTRACT Shooting range activities risk contaminating the soil, posing potential risks to human health, the local biota, and water sources. Considering that soil organisms are the first to be affected by contamination, this study aimed to evaluate the initial growth of the leguminous tree Albizia polycephala and its association with microbes in soil taken fr

3. 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

4. Seed germination and development of orchid seedlings (Cyrtopodium saintlegerianum) with fungi
Resumo Fungos do complexo Rhizoctonia são micorrízicos de orquídeas e podem germinar suas sementes e desenvolver as plântulas. Neste contexto, nosso objetivo foi selecionar um isolado fúngico para promover a germinação e o desenvolvimento de plântulas de Cyrtopodium saintlegerianum. Foram encontrados pelotons nas raízes desta orquídea e foram ident

5. Arbuscular mycorrhizal fungi and auxin associated with microelements in the development of cuttings of Varronia leucocephala
RESUMO Varronia leucocephala é uma planta utilizada pela população para fins terapêuticos. Um dos maiores problemas para produção de mudas dessa espécie é o baixo percentual de enraizamento. Objetivou-se estabelecer um protocolo de enraizamento de estacas de V. leucocephala utilizando fitorreguladores e microelementos associados com fungos micorrízi

6. Root fungal associations in some non-orchidaceous vascular lithophytes
ABSTRACT Plant roots in natural ecosystems are colonized by a diverse group of fungi among which the most common and widespread are arbuscular mycorrhizal (AM) and dark septate endophyte (DSE) fungi. Though AM and DSE fungal associations are well reported for terricolous plant species, they are rather poorly known for lithophytic plant species. In this study

7. The epiphytic orchids Ionopsis utricularioides and Psygmorchis pusilla associate with different Ceratobasidium lineages at Valle del Cauca, Colombia
In Orchidaceae, association with symbiotic fungi is required for seed germination and seedling development, thereby being the main energy source during the first steps of germination. Colombia is one of the countries with the greatest biodiversity of orchids, with an estimated 3,200 species, but few studies on orchid mycorrhiza have been conducted. In our st

8. Arbuscular mycorrhizal colonization in Asteraceae from white sand savannas, in Pinar del Río, Cuba
Asteraceae family shows a great diversity in Cuba and presents threatened taxons in high number. Pinar del Río has 19 threatened species belonging to this family and three of them are characteristic of a sandy (quartzitic) soil at the Reserva Florística Manejada San Ubaldo-Sabanalamar (Floristic Reserve San Ubaldo-Sabanalamar). The arbuscular mycorrhizal s

9. Espécies tropicais de pteridófitas em associação com fungos micorrízicos arbusculares em solo contaminado com arsênio
The symbiosis of plants with mycorrhizal fungi represents an alternative to be considered during the processes of revegetation and rehabilitation of arsenic-contaminated soil. The aim of this study was to evaluate under greenhouse conditions the effect of arsenic on the mycorrhizal association of two species of tropical fern (Thelypteris salzmannii and Dicra

10. Dependência micorrízica de diferentes culturas anuais, adubos verdes e pastagens em solos de cerrado.
ABSTRACT: The arbuscular mycorrhizal fungi in the soil may establish an association with plant roots (mycorrhiza) which benefits the nutrient absorption by the plants and increase the effects of the applied inputs on plant growth. Then, to make profit of this association, it is recommended to increase and diversity fungi in the soil, mainly in those where it

11. Fungos micorrízicos arbusculares em amendoim forrageiro (Arachis pintoi Krap. e Greg.).
Este trabalho foi realizado na Embrapa Agrobiologia em Seropédica,RJ, no km 7 da BR 465 (antiga rodovia Rio-São Paulo), com o objetivo de avaliar a associação de fungos micorrízicos arbusculares (FMAs) com o amendoim forrageiro (Arachis pintoi) em quatro situações de cultivo. 0 primeiro estudo avaliou a associação do A. pintoi com FMAs autoctones, a

12. The role of mycorrhization helper bacteria in the establishment and action of ectomycorrhizae associations
More than 95 % short roots of most terrestrial plants are colonized by mycorrhizal fungi as soon as they emerge in the upper soil profiles. The establishment of mycorrhizal association involves profound morphological and physiological changes in root and fungus. It is affected by other rhizospheric microorganisms, specifically by the bacteria. Bacteria may h
