Diversity of seed mineral composition of Phaseolus vulgaris L. germplasm
Pinheiro, C.; Baeta, J.P.; Pereira, A.M.; Domingues, H.; Ricardo, C.P.A collection of 155 accessions of ancient Portuguese common beans (Phaseolus vulgaris L.) was evaluated in relation to the content of 8minerals (Zn, Cu, Fe, Mn, Ca, Mg, P and K) important for human nutrition. A high degree of variability for P, Fe, Zn, Cu, Mn and Ca was observed in the collection. Total correlation matrix analysis revealed the existence of two important sets of strong positive correlations (P ...
Expression of Lupinus albus PR-10 proteins during root and leaf development
Pinto, Paula; Ribeiro, A.; Regalado, A. P.; Rodrigues-Pousada, C.; Ricardo, C. P. P.Based on the NH2-terminal sequence of three PR-10 isoforms previously identified in Lupinus albus leaves and a conserved amino-acid region in the PR-10 proteins from leguminosae, a pair of oligonucleotides was designed and used to amplify the corresponding cDNA fragment from a L. albus leaves cDNA library. A fragment of DNA of 200 bp was isolated from the polymerase chain reaction (PCR) mixture and subsequently...
Watering and mineral supply effects on plant production, on hydrosoluble metabo...
Matos, O.; Baptista, S.; Passarinho, J.A.; Delgado, F.M.G.; Ricardo, C.P.; Vilas-Boas, L.Calamintha bactica, Origonum vulgaris and Cuminum cyminum have been studied for their capacities as a source of antifungal compounds. One set of these plants grown under water stress. The other set of plants was submitted to different mineral nutrition. The plant material obtained after grinding, were extracted with MeOH or EtOAc, fractionated with organic solvents, and tested for their antifungal properties. C...
Lupinus albus L. pathogenesis-related proteins that show similarity to PR-10 pr...
Pinto, Paula; Ricardo, C. P. P.We describe a group of three acidic proteins, pathogenesis-related (PR)-p16.5a, PR-p16.5b, and PR-p16.5c, that accumulate in the leaves of Lupinus albus L. cv Rio Maior plants when infected with the fungus Colletotrichum gloeosporioides Penz. These proteins co-migrate in sodium dodecyl sulfate-polyacrylamide gels as a single band of 16.5 kD, behaving as charge isomers, and are related to several members of the ...
Novas perspectivas de utilização para o Coriandrum sativum L.
Delgado, F.M.G.; Ricardo, C.P.; Rauter, A.P.O coentro, Coriandrum sativum L., pertence à família Umbelliferae e, é uma planta, anual aromática, com centro de origem no Norte de África e Ásia ocidental, sendo espontânea em vários países mediterrânicos. É cultivado em Portugal pelo aroma e sabor característico das suas folhas jovens. Estas são caracterizadas par serem ternapinadas e, pela sua utilização quando verdes, em diverso pratos da cozinha regional,...
