Citrus psorosis virus 24K protein interacts with citrus miRNA precursors, affects their processing and subsequent miRNA accumulation and target expression
Reyes, Carina Andrea; Ocolotobiche, Eliana Evelina; Marmisollé, Facundo E.; Robles Luna, Gabriel; Bazzini, Ariel Alejandro; Asurmendi, Sebastian; García, María Laura (2016-04)Sweet orange (Citrus sinensis), one of the most important fruit crops worldwide, may suffer from disease symptoms induced by virus infections, thus resulting in dramatic economic losses. Here, we show that the infection ... -
Metabolic and miRNA profiling of TMV infected plants reveals biphasic temporal changes
Bazzini, Ariel Alejandro; Manacorda, Carlos Augusto; Tohge, Takayuki; Conti, Gabriela; Rodriguez, Maria Cecilia; Nunes Nesi, Adriano; Villanueva, Sofía; Fernie, Alisdair R.; Carrari, Fernando; Asurmendi, Sebastian (2011-12-12)Plant viral infections induce changes including gene expression and metabolic components. Identification of metabolites and microRNAs (miRNAs) differing in abundance along infection may provide a broad view of the pathways ... -
The overexpression of antifungal genes enhances resistance to rhizoctonia solani in transgenic potato plants without affecting arbuscular mycorrhizal symbiosis
Fernandez Bidondo, Laura; Almasia, Natalia Ines; Bazzini, Ariel Alejandro; Colombo, Roxana; Hopp, Horacio Esteban; Vazquez Rovere, Cecilia; Godeas, Alicia (Elsevier, 2019-10)The biological control of fungal diseases through the use of genetically modified (GM) plants could decrease the input of chemical pesticides. To overcome possible losses in potato (Solanum tuberosum) yield because of ... -
Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants
Almasia, Natalia Ines; Bazzini, Ariel Alejandro; Hopp, Horacio Esteban; Vazquez Rovere, Cecilia (Wiley-Blackwell, 2008-05)Snakin‐1 (SN1), a cysteine‐rich peptide with broad‐spectrum antimicrobial activity in vitro, was evaluated for its ability to confer resistance to pathogens in transgenic potatoes. Genetic variants of this gene were cloned ... -
Virus infection elevates transcriptional activity of miR164a promoter in plants
Bazzini, Ariel Alejandro; Almasia, Natalia Ines; Manacorda, Carlos Augusto; Mongelli, Vanesa Claudia; Conti, Gabriela; Maroniche, Guillermo Andrés; Rodriguez, Maria Cecilia; Distefano, Ana Julia; Hopp, Horacio Esteban; Del Vas, Mariana; Asurmendi, Sebastian (BioMed Central, 2009-12)Background: Micro RNAs (miRs) constitute a large group of endogenous small RNAs that have crucial roles in many important plant functions. Virus infection and transgenic expression of viral proteins alter accumulation and ...
