Effect of competitive interactions between ectomycorrhizal and saprotrophic fun...

In Northeast of Portugal the macrofungal community associated to chestnut tree (Castanea sativa Mill.) is rich and diversified. Among fungal species, the ectomycorrhizal Pisolithus tinctorius and the saprotroph Hypholoma fasciculare are common in this habitat. The aim of the present work was to assess the effect of the interaction between both fungi on growth, nutritional status and physiology of C. sativa seed...

In Northeast of Portugal the macrofungal community associated to chestnut tree (Castanea sativa is rich and diversified. Among fungal species, the ectomycorrhizal Pisolithus tínctorius and the saprotroph Hypholoma fasciculare are common in this habitat. The aim of the present work was to assess the effect of the interaction between both fungi on growth, nutritional status and physiology of C. satíva seedlings. ...

HydHf, a hydrophobin gene from the saprophytic fungus Hypholoma fasciculare

European chestnut tree (Castanea sativa Mill.) is an economical important culture due to the production of high quality wood and fruit. Portugal is the second largest producer of chestnuts, for which the Northern region contributes for more than 85% of Portuguese production. A saprotrophic fungus was recently isolated from Trás-os-Montes chestnut orchards that interferes with chestnut root mycorrhization and di...

A importância das interacções entre fungos do solo em agroecologia

Os microrganismos vivem no solo sob a forma de comunidades complexas, sendo constantes as interacções que estabelecem entre si e com as raízes das plantas. Esta enorme diversidade de interacções contribui, de forma preponderante, para a fertilidade do solo, desenvolvimento, nutrição e sanidade das plantas. Ao nível da comunidade fúngica do solo é possível observar vários tipos de interacção entre diferentes esp...

Transcriptome of Quercus suber challenged by drought, salinity, and oxidative s...

Comunicação em painel ; The cork oak (Quercus suber) forest (the “montado”) is a unique and emblematic resource for Portugal, due to its ecological, socio-economic significance, and the commercial value of cork. Plant abiotic stresses, particularly reduced water availability and extreme temperatures, are substantial constraints to agricultural and agro-forestry production. In the particular case of cork oak, t...

Global characterization of the Quercus suber ectomycorrhizal transcriptome usin...

Comunicação em painel ; In temperate forests, trees live in symbiosis with fungi and depend on them for their survival. Species from the Fagaceae family, including oaks, establish a symbiotic relationship in their roots with basidiomycetous fungi, called ectomycorrhizas (ECM). ECM symbiosis is essential for the life and health of trees in temperate and boreal forests where it plays a major role in nutrient cyc...

A strategy for the identification of new abiotic stress determinants in arabido...

Since the sequencing of the Arabidopsis thaliana genome in 2000, plant researchers have faced the complex challenge of assigning function to thousands of genes. Functional discovery by in silico prediction or homology search resolved a significant number of genes, but only a minor part has been experimentally validated. Arabidopsis entry into the post-genomic era signified a massive increase in high-throughput ...

Influence of hypholoma fasciculare in portuguese chestnut groves sustainability

The chestnut tree (Castanea sativa) has an enormous economic importance at national level, mainly due to the value of the fruit (chestnut) and the high quality of the wood. The presence of the fungus Hypholoma fasciculare has been observed in chestnut orchard soils of Trás-os-Montes (Portugal). Although it is described as being a saprophyte, preliminary studies have demonstrated that H. fasciculare could cause ...

Study of competitive interactions between ectomycorrhizal and saprotrophic fung...

European chestnut tree (Castanea sativa Mill.), as fruit and wood producers, have a great economic importance in Trás-os-Montes region (Northeast of Portugal). In this agro-ecosystem, the Hypholoma fasciculare and the Pisolithus tinctorius are the most commonest fungi among the saprophytic and mycorrhizal trophic groups, respectively. Although, interactions between ectomycorrhizal and saprotrophic fungi have be...
