Molecular approach to characterize ectomycorrhizae fungi from Mediterranean pin...
Ragonezi, Carla; Caldeira, A. Teresa; Martins, M. Rosário; Salvador, Cátia; Santos-Silva, Celeste; Ganhão, Elsa; Klimaszewska, KrystynaStone pine (Pinus pinea L.), like other conifers, forms ectomycorrhizas (ECM), which have beneficial impact on plant growth in natural environments and forest ecosystems. An in vitro co-culture of stone pine microshoots with pure mycelia of isolated ECM sporocarps was used to overcome the root growth cessation not only in vitro but also to improve root development during acclimation phase. Pisolithus arhizus (S...
O-coumaric acid ester, a potential early signaling molecule in Pinus pinea and ...
Ragonezi, Carla; Teixeira, Dora; Caldeira, Ana Teresa; Martins, Maria do Rosário; Santos Silva, Celeste; Ganhão, Elsa; Klimaszewska, KrystynaDuring ectomycorrhizal (ECM) establishment, biochemical signals lead to the development of complex structures in both the plant and the fungus that ultimately result in the formation of an ectomycorrhiza. The cross-talk between partners begins before physical contact. Our objective was to investigate the chemical nature of the signals during the first stages of in vitro mycorrhization of Pinus pinea with Pisoli...

Ecologie de Amanita ponderosa et gestion des écosystèmes
Santos-Silva, Celeste; Machado, Helena; Guinberteau, JacquesAmanita ponderosa (Malençon & R. Heim) est une espèce de champignon printanière associée aux régions méditerranéennes, très recherchée au niveau régionale et utilisée dans la gastronomie locale. Cette espèce symbiotique bien adaptée à l’écosystème de type « montado » avec chêne-liège ou chêne-vert constitue un modèle d'étude fondamental pour sa conservationet gestion. Son aire de distribution naturelle est limi...
Diagnostics mycosylvicoles à l'échelle Massif
Santos-Silva, Celeste; Machado, Helena; Guinberteau, Jacques; Rondet, JeanCe document est réalisé dans le cadre du projet Micosylva. Micosylva est un projet scientifique et technique européen cofinancé par des aides FEDERiNTERREG. L’objectif est de promouvoir en Europe une gestion multifonctionnelle et durable des forêts qui intègre et valorise les fonctions écologiques et socioéconomiques des champignons sylvestres comestibles. Afin de réaliser ce projet, sur la base d’une coopérati...
Diversidade fúngica no Baixo Alentejo - Diversidade de macrofungos em povoament...
Santos-Silva, CelesteA necessidade de proteger e conservar a biodiversidade e os recursos naturais tem vindo a assumir um papel de destaque, uma prioridade e uma preocupação generalizada na comunidade científica e, cada vez mais, na sociedade actual, face às constantes ameaças e impactes negativos inerentes ao desenvolvimento. É ainda diminuto o conhecimento sobre a riqueza e a diversidade das comunidades micológicas do nosso País,...
Macrofungal diversity in Montado ecosystems – Management and Sustainability
Santos-Silva, Celeste; Louro, RogérioIn order to discuss new management strategies and point out whose silvicultural actions ensure macrofungal communities sustainability in montado ecosystems, studies have been developed on how macrofungal richness and fruitbody production varies in relation to several vegetation factors (canopy cover, proximity of crown projection area, shrub cover and herbaceous cover). The sporocarp surveys were conducted in r...
The use of ectomycorrhizal fungi to restore root growth during in vitro rooting...
Santos-Silva, Celeste; Louro, Rogério; Ragonezi, Carla; Caldeira, Ana Teresa; Martins, Rosário; Klimaszewska, Kristina; Dias, Luis; Ganhao, ElsaThe ICAAM Institute aims to study Mediterranean forest ecosystems in all aspects. Our Plant Breeding and Biotechnology Laboratory of ICAAM has always been involved in biotechnology of Mediterranean woody species, and has developed various in vitro techniques for vegetative propagation of Quercus and Pinus (Ragonezi et al. 2010, Zavattieri et al. 2009). The power of clonal propagation for the improvement of thes...
Canopy cover influence on macrofungal richness and sporocarp production in Mont...
Santos-Silva, Celeste; Louro, Rogério; Gonçalves, AnaIn this study we aimed to find out how macrofungi richness and sporocarp production varies in relation to both canopy cover and proximity of crown projection area, in order to discuss strategies and point out management actions that ensure macrofungal communities sustainability in montado ecosystems. The sporocarp survey was conducted once every two weeks, from October to February, between 2007 and 2009 in two ...
