37. Response of an endangered tree species from Caatinga to mycorrhization and phosphorus fertilization
Schinopsis brasiliensis is an endangered tree species found in the Caatinga biome. It presents a characteristic slow development and difficult propagation, although it has been traditionally exploited in the region. Application of arbuscular mycorrhizal fungi (AMF) and phosphorus (P) fertilization may be beneficial to S. brasiliensis development at the seed

38. Seasonality and mycorrhizal colonization in three species of epiphytic orchids in southeast Mexico
Orchids establish symbiosis with Rhizoctonia mycorrhizal fungi, forming the characteristic pelotons within the cells of the root cortex. Under natural conditions, terrestrial and epiphytic orchids have different levels of dependence upon the fungal symbiont, although various authors have mentioned that once orchid plants reach maturity the interaction become

39. Marginalidade, etnicidade e penalidade na cidade neoliberal: uma cartografia analítica
Este artigo elabora uma cartografia analítica do programa de pesquisa perseguido ao longo dos três livros do autor: Urban outcasts (2008), Punishing the poor (2009) e Deadly symbiosis: race and the rise of the penal State (no prelo). Nessa trilogia, são desfeitos os nexos triangulares entre fragmentação de classe, divisão étnica e remodelagem do Estad

40. Symbiotic nitrogen-fixing bacterial populations trapped from soils under agroforestry systems in the Western Amazon
Cowpea (Vigna unguiculata) is an important grain-producing legume that can forego nitrogen fertilization by establishing an efficient symbiosis with nitrogen-fixing bacteria. Although inoculating strains have already been selected for this species, little is known about the genotypic and symbiotic diversity of native rhizobia. Recently, Bradyrhizobium has be

41. Copper resistance of different ectomycorrhizal fungi such as Pisolithus microcarpus, Pisolithus sp., Scleroderma sp. and Suillus sp.
Environments contaminated with heavy metals negatively impact the living organisms. Ectomycorrhizal fungi have shown important role in these impacted sites. Thus, this study aimed to evaluate the copper-resistance of ectomycorrhizal fungi isolates Pisolithus microcarpus - UFSC-Pt116; Pisolithus sp. - UFSC-PT24, Suillus sp. - UFSM RA 2.8 and Scleroderma sp. -

42. Interrelação bactérias (MHB) e FMA : estratégia para estimular a eficiência simbiótica e micorrização de sabiá. / Bacteria (MHB) and FMA interrelation : a strategy to stimulate the symbiotic efficiency and mycorrhizal of sabiá.
A utilização de plantas associadas simbioticamente, com bactérias fixadoras de N2 e fungos micorrízicos arbusculares (FMA), constitui uma estratégia eficiente para acelerar a recuperação de áreas impactadas além de reduzir consideravelmente os custos com a mesma. O conceito de mycorrhiza helper bacteria (MHB) tem sido introduzido e discutido devido

43. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

44. Expression of phenazine biosynthetic genes during the arbuscular mycorrhizal symbiosis of Glomus intraradices
To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previous

45. Physiological and symbiotic diversity of Cupriavidus necator strains isolated from nodules of Leguminosae species
Biological nitrogen fixation, performed by diazotrophic bacteria, plays an important role in the maintenance of agricultural systems, as it contributes with significant amounts of the nitrogen (N) needed for plant growth, totally or partially exempting the use of industrial N fertilisers. Twenty-five bacterial strains isolated from nodules of Leucaena leucoc

46. 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

47. Control of uncertainties within an interdisciplinary design approach of a robust high heel
Within this paper the combination of several methods, developed and used in Collaborative Research Center (CRC) 805 - "Control of Uncertainties in Load Carrying Systems in Mechanical Engineering" of the DFG (German Research Foundation), is used to demonstrate the development of a load carrying system under uncertainty. The development starts with the identif

48. Chitinase activities, scab resistance, mycorrhization rates and biomass of own-rooted and grafted transgenic apple
This study investigated the impact of constitutively expressed Trichoderma atroviride genes encoding exochitinase nag70 or endochitinase ech42 in transgenic lines of the apple cultivar Pinova on the symbiosis with arbuscular mycorrhizal fungi (AMF). We compared the exo- and endochitinase activities of leaves and roots from non-transgenic Pinova and the trans
