Adventitious root formation in olive (Olea europaea L.) microshoots: anatomical...
Mecedo, E.; Vieira, C.; Carrizo, D.; Porfirio, S.; Hegewald, H.; Arnholdt-Schmitt, B.; Calado, M.L.; Peixe, A.Trials were performed using in vitro-cultured microshoots of the olive (Olea europaea L.) cultivar ‘Galega vulgar’, as initial explants, to identify histological events and modifications in peroxidase and polyphenol oxidase activities during adventitious root formation. Explant bases were submitted to a 10 s quick-dip treatment to promote rooting, using a sterile solution of 14.7 mM indole-3-butyric acid (IBA)....
Formação de raízes adventícias em microestacas de oliveira (Olea europaea L.); ...
Macedo, E.; Vieira, C.; Carrizo, D.; Porfírio, S.; Holger, H.; Arnholdt-Schmitt, B.; Calado, M.L.; Peixe, A.Com o objetivo de identificar tanto fenómenos histológicos como alterações na atividade das peroxidases e polifenoloxidases durante a formação de raízes adventícias, em oliveira realizaram-se ensaios utilizando microestacas da cultivar ‘Galega vulgar’ previamente instalada em cultura in vitro. As bases dos explantes foram submetidas a um tratamento indutor do enraizamento, por imersão rápida (10 segundos) numa ...
Coreceptor Usage by HIV-1 and HIV-2 Primary Isolates: The Relevance of CCR8 Che...
Calado, M; Matoso, P; Santos-Costa, Q; Espirito-Santo, M; Machado, J; Rosado, L; Antunes, K; Mansinho, K; Lopes, MM; Maltez, F; Santos-Ferreira, MOThe human immunodeficiency virus replication cycle begins by sequential interactions between viral envelope glycoproteins with CD4 molecule and a member of the seven-transmembrane, G-protein-coupled, receptors' family (coreceptor). In this report we focused on the contribution of CCR8 as alternative coreceptor for HIV-1 and HIV-2 isolates. We found that this coreceptor was efficiently used not only by HIV-2 but...
Hydatidosis in Portugal: a mitochondrial phylogeny approach
Beato, S.; Calado, M. M.; Parreira, R.; Grácio, M. A. A.Hydatidosis is a worldwide zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus. The taxonomy and phylogeny of the genus Echinococcus has been a controversial issue for several years but with the usage of molecular tools to characterize the etiological agents these aspects had been clarified and a new classification has been proposed and is now widely accepted. The aim of this work is to ...
