RESUMEN.- El objetivo de este estudio consistió en un relevamiento de las principales enfermedades hereditarias BLAD, DUMPs y Citrulinemia, en una población representativa de terneras Holando de la región este del Uruguay utilizando el panel GGP-BovineLDv3, así como en el análisis de la frecuencia del alelo mutante de BLAD desde que fue reportado por primera vez en Uruguay.

Previous to Next Generation Sequencing (NGS), a different technology allowed science to drive through the roads of genetic analysis, the microarray technology. Shortly, microarrays consist of a grid of spots, with each spot containing single-stranded DNA sequences attached to a solid surface. For microarray analysis, the mRNA must be extracted from the sample and converted to a labeled cDNA strand, and later added to the microarray device.

ABSTRACT.- Conventional viticulture involves a high use of inputs that negatively impact ecosystem services and biodiversity. Traditionally, vineyards are rainfed systems and vegetation is removed or sprayed with herbicides to avoid excessive competition for water and nutrients. Introducing cover crops can positively promote several ecosystem services and particularly soil and crop health and biodiversity.

Grassland biomes provide valuable ecosystem services, including nutrient cycling. Organic phosphorus (Po) represents more than half of the total P in soils. Soil microorganisms release organic P through enzymatic processes, with alkaline phosphatases, acid phosphatases and phytases being the key P enzymes involved in the cycling of organic P.

ABSTRACT.- Controlling a pest species raises questions about the harmful effects its eradication could cause in ecosystems. Currently, in Uruguay are being analyzed strategies to eradicate the New World Screwworm (NWS), Cochliomyia hominivorax (Diptera:Calliphoridae), an obligatory ectoparasite that causes myiasis in warm-blooded vertebrates, including humans. The loss of a species implies a risk of secondary extinctions and cascading effects that depend on the ecological function of the species and the capacity of the rest of the species with which it interacts to compensate for its loss.

Agrociencia Uruguay was founded 25 years ago with the aim of communicating, in open access mode, the research results in the field of agriculture, mainly research carried out in the region. To fulfill this objective, and given the different disciplines that make up the agricultural sciences, the journal was divided from its origin until the present into sections in which original knowledge is published.

El objetivo del presente trabajo es mejorar la calidad nutricional del grano de soja, a través de la edición de genes que controlan el tamaño y composición del grano. Este trabajo se centró en generar mutaciones de tipo knockout en genes asociados con el tamaño de la semilla (BS) y con la calidad de proteínas de grano, utilizando el sistema CRISPR-Cas9.
