Comparison of chickpea rhizobia isolates from diverse Portuguese natural popula...
Laranjo, Marta; Branco, Cristina; Rebeca, Soares; Alho, Luís; Carvalho, Mário; Oliveira, SolangeAbstract: Aims: To test the hypothesis that differences in chickpea yields obtained in four distinct Portuguese regions (Beja, Elvas-Casas Velhas , Elvas-Estacao Nacional de Melhoramento de Plantas (ENMP) and Evora) could be due to variation between the natural rhizobia populations. Methods and Results: Estimation of the size of the different rhizobial populations showed that Elvas-ENMP population was the large...
Hybrids between cork oak and holm oak: Isoenzyme analysis
Oliveira, Paulo; Custódio, Ana Cristina; Branco, Cristina; Reforço, Isabel; Rodrigues, Fernanda; Varela, Maria Carolina; Meierrose, CarolaHybrids between cork oak and holm oak occur in a large range of overlap between these two species in Portugal, and the subsequent crosspollination involving the hybrids and cork oak has been postulated to result in some of the worst cork-producing trees in Portugal. A methodological framework was set for the routine large scale detection of hybrid genotypes using isoenzyme analysis. The effectiveness of isoenzy...
Complete bilateral carotid artery occlusion
Reis Pina, Paulo; Pacheco Pereira, João; Branco, Cristina; Silva, Francisco; Pimenta da Graça, JoséPatients with an internal carotid artery occlusion have been identifi ed as having an increased risk of an ischemic stroke.Complete bilateral carotid occlusion is a rare condition.Several risk factors are involved in the development of carotid atherosclerosis.The hemodynamic consequences of cerebral blood fl ow obstruction may be reduced through the development of collateral circulatory pathways.
