Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia
Garcia, Araceli Nora; Ayub, Nicolás Daniel; Fox, Ana Romina; Gomez, Maria Cristina; Dieguez, Maria Jose; Pagano, Elba Maria; Berini, Carolina Andrea; Muschietti, Jorge Prometeo; Soto, Gabriela Cinthia (BMC Plant Biology, 2014-09-17)Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ... -
Caracterización del proceso de fabricación de macroporos sobre sustrato de silicio por método electroquímico = Characterization of fabrication process of micropores on silicon substrate by electrochemical method
Der, Manuel; Olmos, Carol; Rosero Yanez, Gustavo Iván; Santizo, Itzel; Fernandez, Tamara; Dieguez, Maria Jose; Sacco, Francisco; Granell, Pablo; Golmar, Federico; Lerner, Betiana; Lasorsa, Carlos; Perez, Maximiliano (Universidade Federal do Rio de Janeiro, 2018-07)En el presente trabajo se estudió el proceso de fabricación de una serie de macroporos sobre obleas de silicio cristalino mediante la técnica wet etching. Se evaluó la incidencia de distintos factores como el voltaje, la ... -
Characterization and comparative analysis of the genome of Puccinia sorghi Schwein, the causal agent of maize common rust
Rochi, Lucía; Dieguez, Maria Jose; Burguener, Germán; Darino, Martín Alejandro; Pergolesi, María Fernanda; Ingala, Lorena Romina; Cuyeu, Alba Romina; Turjanski, Adrián; Kreff, Enrique D.; Sacco, Francisco (Elsevier, 2018-03)Rust fungi are one of the most devastating pathogens of crop plants. The biotrophic fungus Puccinia sorghi Schwein (Ps) is responsible for maize common rust, an endemic disease of maize (Zea mays L.) in Argentina that ... -
Characterization and use in wheat breeding of leaf rust resistance genes from durable varieties
Dieguez, Maria Jose; Lopez, Micaela; Altieri, Emiliano; Pergolesi, María Fernanda; Dabove, Marisol Alicia; Cuyeu, Alba Romina; Justus, Nadia Alejandra; Kandus, Mariana Virginia; Ingala, Lorena Romina; Sacco, Francisco (MDPI, 2021-11)Leaf rust is one of the most significant diseases of wheat worldwide. In Argentina, it is one of the main reasons for variety replacement that becomes susceptible after large-scale use. Some varieties showed durable ... -
Effect of butanol and salt concentration on solid-state nanopores resistance
Vega, Milena; Perez, Maximiliano; Granell, Pablo; Golmar, Federico; Wloka, Carsten; Maglia, Giovanni; Dieguez, Maria Jose; Del Valle, Eva María; Lasorsa, Carlos; Lerner, Betiana (Taylor & Francis, 2016-09)The objective of this study was to demonstrate the possibility of using 1-butanol to reliably detect the open-pore current of pyramidal solid-state nanopores produced in silicon wafers. The nanopores were produced through ... -
Fine mapping of LrSV2, a race-specific adult plant leaf rust resistance gene on wheat chromosome 3BS
Dieguez, Maria Jose; Pergolesi, María Fernanda; Velásquez, Silvia Melina; Ingala, Lorena Romina; López, M.; Darino, Martin Alejandro; Paux, Etienne; Feuillet, Catherine; Sacco, Francisco (Springer, 2014-05)Three leaf rust resistance genes were identified in the durable leaf rust resistant Argentinean wheat variety Sinvalocho MA: the seedling resistance gene Lr3 on distal 6BL and two adult plant resistance genes, LrSV1 and ... -
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
Dieguez, Maria Jose; Petignat, Camila; Ferella, Luciana; Fiorentino, Gabriela A.; Silva, Martha; Dabove, Marisol Alicia; Rosero Yanez, Gustavo Iván; Lopez, Micaela; Pergolesi, María Fernanda; Ingala, Lorena Romina; Cuyeu, Alba Romina; Sacco, Francisco (Springer, 2018-08)A complementary gene to LrSV2 for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked to Lr12 / 31. LrSV2 is a race-specific adult plant leaf rust (Puccinia triticina) resistance ... -
Virulence characterization and identification of maize lines resistant to Puccinia sorghi Schwein. Present in the argentine corn belt region
Darino, Martín Alejandro; Rochi, Lucía; Lia, Veronica Viviana; Kreff, Enrique D.; Pergolesi, María Fernanda; Ingala, Lorena Romina; Dieguez, Maria Jose; Sacco, Francisco (2016-04)Puccinia sorghi Schwein., the causal agent of maize common rust, is an endemic disease in the Argentine Corn Belt region. Virulence surveys of the pathogen population within the region have not been performed; thus, the ...
