Are Sunflower chlorotic mottle virus infection symptoms modulated by early increases in leaf sugar concentration?
Rodriguez, Marianela; Taleisnik, Edith; Lenardon, Sergio Luis; Lascano, Hernan Ramiro (Elsevier, 2010-09-15)Symptom development in a susceptible sunflower line inoculated with Sunflower chlorotic mottle virus (SuCMoV) was followed in the second pair of leaves at different post-inoculation times: before symptom expression (BS), ... -
Biological, Molecular and Phiysiological Characterization of Four Soybean mosaic virus Isolates Present in Argentine Soybean Crops
Maugeri Suarez, M; Rodriguez, Marianela; Bejerman, Nicolas Esteban; Laguna, Irma Graciela; Rodriguez Pardina, Patricia (BioRxiv, 2021-06-10)Soybean mosaic virus (SMV) causes systemic infections in soybean plants, leading to chlorotic mosaic and producing significant yield losses. The virus is widely distributed in all soybean production areas in the world. In ... -
Cassava common mosaic virus infection causes alterations in chloroplast ultrastructure, function and carbohydrate metabolism of cassava plants
Zanini, Andrea Alejandra; Di Feo, Liliana Del Valle; Luna, Dario Fernando; Paccioretti, Pablo; Collavino, Agostina; Rodriguez, Marianela (Wiley, 2021-01)Cassava common mosaic virus (CsCMV) is a potexvirus that causes systemic infections in cassava plants, leading to chlorotic mosaic and producing significant yield losses. To date, the physiological alterations and the ... -
Interactions between soybean, Bradyrhizobium japonicum and Soybean mosaic virus: the effects depend on the interaction sequence
Andreola, Sofia; Rodriguez, Marianela; Parola, Rodrigo; Alemano, Sergio Gabriel; Lascano, Hernan Ramiro (2019-06-25)The symbiotic interaction between soybean and nitrogen-fixing rhizobia can lead to plant growth promotion and induced systemic responses. Symbiotic interactions may increase tolerance/resistance to abiotic/biotic stress ... -
Negative short-term salt effects on the soybean–Bradyrhizobium japonicum interaction and partial reversion by calcium addition
Muñoz, Nacira Belen; Rodriguez, Marianela; Robert, German; Lascano, Hernan Ramiro (CSIRO Publishing, 2013-09-05)The short-term (2 h) effects of salt stress (50 and 150 mM NaCl) on early events of soybean– Bradyrhizobium japonicum (rhizobia) interaction were analysed, determining the following parameters in root hair with or without ... -
Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom
Rodriguez, Marianela; Muñoz, Nacira Belen; Lenardon, Sergio Luis; Lascano, Hernan Ramiro (Taylor & Francis, 2013)Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. These elements are major determinants of the ... -
The chlorotic symptom induced by Sunflower chlorotic mottle virus is associated with changes in redox-related gene expression and metabolites
Rodriguez, Marianela; Muñoz, Nacira Belen; Lenardon, Sergio Luis; Lascano, Hernan Ramiro (Elsevier, 2012-08-18)Systemic infections are commonly associated with changes in host metabolism and gene expression. Sunflower chlorotic mottle virus (SuCMoV) causes systemic infection with sugar increase, photoinhibition and increase in ... -
TOR and SnRK1 signaling pathways in plant response to abiotic stresses: Do they always act according to the "yin-yang" model?
Rodriguez, Marianela; Parola, Rodrigo; Andreola, Sofia; Pereyra, Cintia; Martínez-Noël, Giselle (2019-08-13)Plants are sessile photo-autotrophic organisms continuously exposed to a variety of environmental stresses. Monitoring the sugar level and energy status is essential, since this knowledge allows the integration of external ...
