Díaz, E. M. ; Sánchez Elordi, Elena ; Santiago, Rocío ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | JSciMed Central | 2016-08-22Lichens are specific symbiotic associations between photosynthetic algae or cyanobacteria and heterotrophic fungi forming a double entity in which both components coexist. Specificity required for the lichen establishment can be defined in this [...]texto impreso
Díaz Peña, Eva María ; Ampe, Christophe ; van Troys, Maleen ; Vicente Manzanares, M. ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | Elsevier | 2016Lichenized Nostoc cells isolated from the lichen Peltigera canina develop chemotaxis towards a lectin purified from the lichen thallus. Similar movements in unicellular eukaryotes require actin and myosin to generate contraction and relaxation a[...]texto impreso
Vicente Córdoba, Carlos ; Alarcón, B. ; Santiago, Rocío ; Armas, R. D. ; Sánchez Elordi, Elena ; Legaz González, María Estrella | Trade Science | 2017-03-25A chemical simulation of the infection of sugar cane leaves by smut (Sporisorium scitamineum), using an elicitor isolated from the growing fungal mycelium, provokes an increase of the pattern of lignification of both sclereids and xylem elements[...]texto impreso
Pereira, Eugênia C. ; Silva, Nicaçio H. da ; Buril, M. L. L. ; Martins, Mônica C.B. ; Silva, Hianna A. M. F. ; Falcão, Emerson Peter S. ; Oliveira, Helinando P. de ; Costa, Mateus Matiuzzi da ; Legaz González, María Estrella ; Santiago, Rocío ; Vicente Córdoba, Carlos | Springer | 2020-05-12Lichens are the symbiotic organisms formed by one species of fungus associated to one or more species of green algae and/or cyanobacteria. The relationship between these organisms results in a metabolism that culminates in a production of exclus[...]texto impreso
Pereira, Eugênia C. ; Martins, Mônica C.B. ; Buril, M. L. L. ; Santiago, Rocío ; Da S. Falcão, Emerson Peter ; Da Silva, Nicácio H ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | JSciMed Central | 2017-07-13It can be obtained from lichens biologically-active extracts and pure substances, many of them of phenolic nature. They are usually obtained by using organic solvents, such as diethyl ether. In this paper the usefulness of ether for the obtainme[...]texto impreso
La ciencia impregna prácticamente todos los aspectos de nuestra vida gracias a la rapidez con la que se genera el conocimiento científico, la velocidad con la que dicho conocimiento se transmite y la profunda tecnificación de nuestra vida cotidi[...]texto impreso
Díaz Peña, Eva María ; Vicente-Manzanares, Miguel ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | Springer | 2015-11Lichenized Nostoc cells isolated from the lichen Peltigera canina develop chemotactic movement towards a lectin purified from the lichen thallus. Inhibitors of cytoskeleton dynamics, such as phalloidin, latrunculin A and blebbistatin, impede cel[...]texto impreso
Sánchez Elordi, Elena ; Baluška, František ; Echevarría, Clara ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Elsevier | 2016Microtubules (MTs) are involved in the germination of Sporisorium scitamineum teliospores. Resistant varieties of sugar cane plants produce defence glycoproteins that prevent the infection of the plants by the ?lamentous fungi Sporisorium scit[...]texto impreso
Sánchez Elordi, Elena ; Contreras, Roberto ; Armas, Roberto de ; Benito Jiménez, Cesar ; Santiago, Rocío ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Science Publishing Group | 2020-07-13Sugarcane is a C4 plant from the NADP-ME family, which performs a double photosynthetic carboxylation. It is a plant specialized in accumulating and storing large amounts of sucrose in the parenchymatous cells of its stalks. Perhaps because of t[...]texto impreso
Sánchez Elordi, Elena ; Morales de los Ríos, L. ; Díaz, E. M. ; Ávila, A. ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | Italian Phytopathological Society | 2016Sugarcane produces and secretes high molecular mass glycoproteins (HMMG) in response to pathogenic infections, wounds or several types of stress. The teliospores of the pathogenic filamentous fungus Sporisorium scitamineum produces smut disease [...]texto impreso
Díaz Peña, Eva María ; Cutrona, Carmen ; Sánchez Elordi, Elena ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | Springer Link | 2016-06In this study, we have used affinity chromatography to purify the lectins from a chlorolichen, Evernia prunastri (L.) Ach., and a cyanolichen, Peltigera canina (Ach.) Schard. These species secrete lectins that display arginase activity in additi[...]texto impreso
