A comprehensive assessment of the transcriptome of cork oak (Quercus suber) thr...

Background: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic inform...

Diversity and fruiting pattern of macrofungi associated with chestnut tree (Cas...

The chestnut (Castanea sativa) agro-ecosystem is of great social, economic and landscape importance in NE Portugal. There are multiple resources associated with this crop, among them fruit and wood production and mushroom harvesting. However, information about the diversity and ecology of macrofungi is very scarce. In this context, the aim of this study was to assess the macrofungal diversity associated with ch...

Identification of fungi isolated from the olive moth (Prays oleae Bern.) based ...

Biological potential of fungi associated to Prays oleae in Trás-os-Montes (Nort...

Olive groves represent an important fraction of the agricultural practices in Portugal, mainly in the region of Trás-os-Montes. Our work pretends to disclose the fungal diversity associated to one of the major olives pests, the Prays oleae Bern. Besides evaluating the extent of the presence of entomopathogenic fungi, we also intend to reveal other promising fungi with potential to be used as biological control ...

Interaction between Hypholoma fasciculare and the ectomycorrhizal fungus Pisoli...

In the past few years, cord-forming basidiomycetes have received considerable attention in their growth strategies in the presence of other fungi (saprotrophic and pathogenic). In the present study, the in vitro interaction between the cord-forming basidiomycete Hypholoma fasciculare and the ectomycorrhizal fungus Pisolithus tinctorius was studied. Dual-cultures were established and the radial fungal growth, hy...

Fungal diversity associated to Prays oleae in Trás-os-Montes (Northeastern regi...

Olive groves are one of the main agricultural activities in the Portuguese region of Trás-os-Montes. They occupy a very large area, where new biological agricultural practices have been increasingly applied. In order to control the pests that attack this culture, using methods that do not rely on chemical substances, an effort must be conducted to achieve new processes. One of the most important pest in the oli...

A importância dos fungos na limitação natural da traça-da-oliveira, Prays oleae...

A traça da oliveira (Prays oleae Bern.) e uma praga chave dos olivais da Península Ibérica, provocando, ano ap6s ano, consideráveis perdas de rendimento. Os meios de protecção contra esta praga são baseados sobretudo em produtos químicos de síntese com implicações ao nível de poluição ambiental, desenvolvimento de resistência e de existência de resíduos nos produtos do olival. Neste contexto 0 conhecimento dos ...

Intraspecific variation of the entomophatogenic fungi Beauveria bassiana collec...

The fungus Beauveria bassiana is a well recognised entomopathogen known to infect hundreds of host species from most of the insect orders. Therefore, the use of this fungus as a biological control agent against insect pests is very promising and several commercial products have already been developed. The natural occurrence of B. bassiana has been reported throughout Spain. Recently, its presence has been also ...

Beauveria bassiana, fungo entomopatogénico da traça-da-oliveira em Trás-os-Mont...

Beauveria bassiana, fungo entomopatogénico da traça-da-oliveira em Trás-os-Mont...

A traça-da- olivelra, Prays oleoe (Bern.), é uma praga chave da oliveira na região de Trás- os-Montes. Uma possível alternativa a luta química contra esta praga, reside na utilização de fungos entomopatogénicos (FE). Dado o desconhecimento da presença e expressão destes fungos em Portugal foi recentemente efectuado o isolamento in vitro de fungos, associados a pupas de traça-da-oliveira parasitadas, provenien...
