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
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
Sánchez Elordi, Elena ; Díaz, Eva María ; Armas, Roberto de ; Santiago, Rocío ; Alarcón, Borja ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Academic Press | 2020-04-17The effects of different environmental stresses on growth, efficiency in biomass production, and on the accumulation of sucrose in sugarcane cultivars are studied. Thermal, nutritional, saline, and drought stresses have similar effects on sensit[...]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 ; Sterling, Roberto M. ; Santiago, Rocío ; Armas, Roberto de ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Elsevier | 2020-01Smut infection alters the transcription of dirigent proteins (DIR) by sugarcane plants. Here, we show that these alterations are associated to an elevated production of cytotoxic lignans. Smut-resistant sugarcane varieties display a fivefold inc[...]texto impreso
Sánchez Elordi, Elena ; Blanch, María ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Isaac Scientific Publishing | 2017-12The aim of the present work is to study the way in which defense glycoproteins, produced by sugar cane plants, retard and modify the crystallization pattern of sucrose. The effect of defense glycoproteins against smut on the crystallization of s[...]texto impreso
La caña de azúcar es uno de los cultivos comerciales más destacados en países tropicales y sub-tropicales, y supone para el mundo la principal fuente de azúcar blanco (Sundar et al., 2015). Por otro lado, la enfermedad del carbón es una de las i[...]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[...]texto impreso
Sánchez Elordi, Elena ; Morales de los Ríos, Laura ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Springer | 2019-03-12Previous studies have already highlighted the correlation between Sporisorium scitamineum pathogenicity and sugarcane polyamine accumulation. It was shown that high infectivity correlates with an increase in the amount of spermidine, spermine an[...]texto impreso
Sánchez Elordi, Elena ; Morales de los Ríos, Laura ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Elsevier | 2015-12Sugar cane cultivars resistant to smut produce a pool of glycoproteins after experimental infection, one of them develops arginine activity. This arginase induces cytoagglutination of smut teliospores but impedes germination. Teliospores also se[...]texto impreso
Sánchez Elordi, Elena ; Baluška, František ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Springer | 2019-09-14Sporisorium scitamineum teliospores possess an organized cytoskeleton involved in important developmental and physiological processes. It has been described that microtubules appear to be fundamental for nucleus translocation during germination [...]
