A brassinosteroid functional analogue increases soybean drought resilience
Perez Borroto, Lucia Sandra; Guzzo, María Carla; Posada, Gisella Anabel; Peña Malavera, Andrea Natalia; Castagnaro, Atilio Pedro; Gonzalez Olmedo, Justo Lorenzo; Coll, Yamilet; Pardo, Esteban Mariano (Nature Research, 2022-07-04)Drought severely affects soybean productivity, challenging breeding/management strategies to increase crop resilience. Hormone-based biostimulants like brassinosteroids (BRs) modulate growth/defence trade-off, mitigating ... -
A strawberry disease caused by Acremonium strictum
Racedo, Josefina; Salazar, Sergio Miguel; Castagnaro, Atilio Pedro; Diaz Ricci, Juan Carlos (Springer, 2013-12)We report Acremonium strictum as the causal agent of a new disease in strawberry plants (Fragaria x ananassa Duch.) in the Northwest of Argentina. Both the structure of conidiophores and the sequence spanning the internal ... -
Avirulent strain of Colletotrichum induces a systemic resistance in strawberry
Salazar, Sergio Miguel; Grellet Bournonville, Carlos Froilan; Chalfoun, Nadia Regina; Castagnaro, Atilio Pedro; Diaz Ricci, Juan Carlos (Springer, 2013-04)Strawberry plants exposed to an avirulent isolate of Colletotrichum fragariae acquired strong resistance against a virulent strain of C. acutatum. Biochemical, morphological and molecular markers indicated that the strong ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
Pardo, E.M.; Vellicce, Gabriel Ricardo; Aguirrezabal, Luis Adolfo Nazareno; Pereyra Irujo, Gustavo Adrian; Rocha, Carla Maria Lourdes; García, M.G.; Prieto Angueira, Salvador; Welin, Björn; Sanchez, J.; Ledesma, Fernando; Castagnaro, Atilio Pedro (Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -
Genetic inheritance analysis of the resistance to a virulent isolate of Colletotrichum acutatum in strawberry based on an octoploid model = Análisis de la herencia genética de la resistencia a un aislado virulento de Colletotrichum acutatum en frutilla basado en un modelo octoploide
Salazar, Sergio Miguel; Ontivero, M.I.; Castagnaro, Atilio Pedro; Mariotti Martinez, Jorge Alberto; Vellicce, Gabriel Ricardo; Diaz Ricci, Juan Carlos (Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2017-12)In the present work we propose a hypothesis to explain the mechanism of the genetic control of resistance to anthracnose and we show an experimental model that may support our hypothesis. The inheritance of the strawberry ... -
Use of AFLP markers to estimate molecular diversity of Phakopsora pachyrhizi
Rocha, Carla Maria Lourdes; Vellicce, Gabriel Ricardo; Garcia, Maria Gabriela; Pardo, Esteban Mariano; Racedo, Josefina; Perera, María Francisca; De Lucia, Adrían Darío; Gilli, Javier Ramon; Bogado, Noelia; Bonnecarrére, Victoria; German, Silvia; Marcelino, Francismar; Ledesma, Fernando; Reznikov, Sebastian; Ploper, Leonardo Daniel; Welin, Bjorn; Castagnaro, Atilio Pedro (2015-11)Background: Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. ...
