Plan S: take Latin America’s long experience on board
(Nature Research, 2019-09-24)We share the spirit of Plan S to achieve full open access to scholarly publications (see go.nature.com/2hszsaf), but we disagree with its implementation guidelines. The plan’s design ignores more than 20 years of widespread ... -
Plant microRNAs: Recent Advances and Future Challenges
(2014-12)MicroRNAs (miRNAs) are small ∼20–24 nt species of non-coding RNAs that modulate plant gene expression by means of gene silencing through sequence-specific inhibition of target mRNAs. MiRNAs derive from pol-II transcription ... -
Plant-Derived Essential Oils and Aqueous Extract as Potential Ingredients for a Biopesticide: Phytotoxicity in Soybean and Activity against Soybean Mosaic Virus
(MDPI, 2023-07-27)Soybean mosaic disease, caused by the soybean mosaic virus (SMV), is responsible for major losses in yield and seed quality worldwide. Although resistant cultivars are used for its prevention and control, an alternative ... -
Plum Pox virus in japanese plum from Argentina: serological detection and molecular characterization of an isolate from cv. Red Beauty
(Wiley, 2014-01)A Plum pox virus (PPV) isolate detected in a Japanese plum orchard in Pocito (San Juan, Argentina) was transmitted mechanically to Prunus tomentosa and Nicotiana benthamiana. DAS-ELISA and DASI-ELISA indicated the virus ... -
Preprints are good for science and good for the public
(Nature Research, 2018-08-29)We disagree with Tom Sheldon’s contention that the preprint ecosystem can present a challenge to accurate and timely journalism (Nature 559, 445; 2018). Restricting when or how preprints are released risks suppressing ... -
Presence of both mating types of Ascochyta rabiei in Argentina suggests potential for sexual reproduction
(Springer, 2020-11-15)The presence of both mating types was tested for in twelve isolates of Ascochyta rabiei in Argentina. A MATspecific PCR assay was performed. Nine of these isolates were identified as MAT1–1 and three of them MAT1–2. This ... -
Primer reporte de Sweet potato leaf curl virus en las provincias de Córdoba y Santiago del Estero de Argentina
(Facultad de Ciencias Exactas Físicas y Naturales, Universidad Nacional de Córdoba, 2016-03)La superficie con batata en Argentina experimentó notable reducción, causada por virosis que ocasionan daños en todas las regiones productoras, debido al intercambio indiscriminado de material de propagación y consiguiente ... -
Proteínas totales y perfiles SDS-PAGE de suelos agrícolas bajo fertilización mineral
(Facultad de Ciencias Exactas Físicas y Naturales, Universidad Nacional de Córdoba, 2019-03)Los microorganismos son fundamentales para el mantenimiento de las funciones de suelos naturales y agrícolas. La identificación de proteínas del suelo podría proporcionar una valiosa información sobre las capacidades ... -
Qualitative and quantitative factors affecting the relationship between Canola leaf spot epidemic and stem base canker (Leptosphaeria maculans) in Argentina
(Springer, 2017-09)Stem base canker caused by Leptosphaeria maculans (SBC) has been reported to affect canola production worldwide. Ascospores infections produce leaf spots (LS) in early vegetative stages. From these initial spots, the fungus ... -
Quantifying the negative impact of clinical diseases on productive and reproductive performance of dairy cows in central Argentina
(Elsevier, 2022-03-15)In dairy herds, cattle experience different health disorders, and their occurrence during lactation may cause important economic losses. The systematic analysis of productive and health records allows us to identify the ... -
Reaction of South American wheat genotypes to wheat streak mosaic virus
(Springer, 2018-08)Wheat streak mosaic virus (WSMV) is an emerging virus in South America that threatens cereal production. Genetic resistance is used in other regions as an effective strategy for management of this disease. The susceptibility ... -
