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 | 2019-11-27Smut 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 ; 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
Alarcón, Borja ; Armas, Roberto de ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Bentham Science Publishers | 2019Aims and Objectives: This study aimed to characterize a coniferyl alcohol dehydrogenase from sugarcane stalks. Also, the purification of CAD from sugarcane stalks was also carried out to study kinetic properties and substrate specificity. Backg[...]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
Martins, M.C.B. ; Lima, M. J. G. ; Santiago, Rocío ; Buril, M. L. L. ; Pereira, Eugênia C. ; Legaz González, María Estrella ; Vicente Córdoba, Carlos ; Silva, Nicaçio H. da | Trade Science Inc. | 2017-03The aim of this paper is related to the modifications of the most usual method for producing USN and others bioactive compounds by the lichen Cladonia substellata to rationalize ecologically the provision of those at large scale. Different cell [...]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
Tigre, R. C. ; Pereira, Eugênia C. ; Da Silva, Nicácio H. ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Elsevier | 2015-05The possibilities for using phenolics, extracted from the lichen Cladonia verticillaris with different organic solvents, as bioherbicides have herein been studied through observation of the ultrastructural changes produced in Lactuca sativa seed[...]texto impreso
Santiago, Rocío ; Martins, Mônica C.B. ; Nascimento, Tais ; Filipe de Barros, Luis ; Vilaça, Matheus ; Emerson, Peter Falcão ; Henriques da Silva, Nicácio ; Legaz González, María Estrella | Canadian Center of Science and Education | 2020-03-19Bionts isolated from thalli of Cladonia verticillaris, immobilized in calcium alginate, produce two depsidones, fumarprotocetraric and protocetraric acids, and the depside atranorin, that exhibit antimicrobial activity against Staphylococcus aur[...]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 [...]texto impreso
Vasconcelos, Talitha L. de ; Oliveira, Andrezza K. de ; Pereira, Eugênia C. ; Silva, Nicaçio H. da ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | 2015-12The lichen Cladonia verticillaris can alter the mineralogical composition of the sandy soils that serve as its main substrate. Soils from Mamanguape, the semiarid land of the northeast of Brazil on which C. verticillaris grows, are mainly compos[...]texto impreso
Díaz, Eva María ; Davó, Nuria ; Vicente Córdoba, Carlos ; Legaz González, María Estrella | Trade Science Inc. | 2015The mycobiont of the lichen Cladonia verticillaris produces two depsidones, protocetraric and fumarprotocetraric acids, in the nature. This last compound is produced from the former depsidone. To study the role of the algal partner in the produc[...]
