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
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
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
Sánchez Elordi, Elena ; Díaz Peña, Eva María ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | International Journal of Pharma and Bio Sciences | 2018-01Sporisorium scitamineum cells, that causes smut disease in sugar cane, respond to Concanavalin A (ConA). This lectin stimulates the cytoagglutination of teliospores, an excessive elongation of germinative tubes and induces morphological changes [...]texto impreso

Sánchez Elordi, Elena ; Vicente Manzanares, M. ; Díaz Peña, Eva María ; Legaz González, María Estrella ; Vicente Córdoba, Carlos | Elsevier | 2016-07A fraction of active glycoproteins isolated from sugarcane cultivars resistant to smut (Sporisorium scitamineum) contains several peptides with different biological activities. One of these proteins is active as a positive chemotactic stimulus o[...]
