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
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

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
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
