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 ... -
First biological data of Ceresa nigripectus [Hemiptera:Membracidae], a common treehopper on alfalfa crops in Argentina
(2014-12)Alfalfa (Medicago sativa L.; Fabaceae) is essential for argentinean agricultural development, but diseases like “witches´ broom», caused by the ArAWB phytoplasma, are limiting factors for the production of this crop. ... -
Osteosarcoma in the Skull of a Holstein Heifer
(Brazilian Association of Veterinary Pathology, 2014-12-22)A-2-year-old heifer showed a mass on the frontal part of the skull. Cytological analysis displayed pleomorphic, polyedric and fusiform cells with extracellular hyaline material. Histologically, the excised mass showed ... -
Cítricos : Guignardia citricarpa Kiely (Mancha negra de los cítricos)
(2015)La mancha negra de los cítricos es una enfermedad del fruto que afecta a su corteza pero no causa podredumbre. El limonero es particularmente sensible y, cuando aparece la enfermedad por primera vez en alguna zona, ... -
Cuantificación de la captura de carbono de Chloris gayana cv Finecut implantada en un sistema pastoril bovino de la Llanura Deprimida Salina de Tucumán y de la vegetación nativa que reemplaza
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2015)En las últimas décadas, el crecimiento de la población humana se evidencia en el deterioro de los recursos naturales. El aumento de la frontera agrícola y de la producción de alimentos para una población creciente ha traído ... -
A strain of Bacillus subtilis subsp. subtilis shows a specific antagonistic activity against the soil-borne pathogen of onion Setophoma terrestris
(2015)Pink Root is among the major diseases of onion and its causal agent, Setophoma terrestris, is one of the most severe pathogens in soils of tropical and subtropical climates. The management of Pink Root is difficult and the ... -
Plasticity in sunflower leaf and cell growth under high salinity
(Wiley, 2015-01)A group of sunflower lines that exhibit a range of leaf Na+ concentrations under high salinity was used to explore whether the responses to the osmotic and ionic components of salinity can be distinguished in leaf expansion ... -
The role of inoculum identity in drought stress mitigation by arbuscular mycorrhizal fungi in soybean
(2015-01)It is well known that arbuscular mycorrhizal fungi (AMF) effects on plant growth largely depend on fungus identity. The objective of this study was to test whether three individual AMF isolates and their mixture mitigate ... -
First report of papaya ringspot virus w infecting momordica charantia in Cuba
(Dipartimento di Scienze del Suolo, della Pianta e degli Alimenti, Università di Bari, 2015-01-16)During a survey conducted in July 2010, severe mosaic and deformations were observed on the leaves of cerasee (Momordica charantia) in Villa Clara, Cuba. The symptoms resembled those induced by Papaya ringspot virus (PRSV) ... -
Efficiency and stability in subtropical beef cattle grazing systems in the northwest of Argentina
(2015-02)The objective of this work was to evaluate the efficiency and stability of cow–calf, fattening and whole cycle beef cattle agro-ecosystems from the subtropical region of Argentina. For this purpose, an agro-ecosystem model ... -
Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina
(Springer, 2015-02)Begomoviruses seriously threaten tomato production in South America. Here, we present the molecular characterization of a novel tomato-infecting begomovirus isolated in Argentina and demonstrate its infectivity. After ... -
