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.

The global growth of meat-based protein consumption is forcing the intensification and development of livestock and farming systems, with long-term consequences for natural systems and resources. The impacts associated with livestock systems include land-use change, global warming, power, and water consumption, and plenty of interdependent issues affecting mutually anthropogenic and natural ecosystems.

El Programa Nacional de Investigación en Producción Frutícola de INIA viene considerando desde el año 2007 el potencial de desarrollo del cultivo frutícola comercial del nogal americano o pecán. Dado el potencial identificado para este rubro en el país, y la falta de conocimiento sobre el manejo del cultivo y su comportamiento en nuestras condiciones, el primer paso para comenzar las investigaciones en pecán fue instalar un ensayo comparativo de cultivares.

ABSTRACT.- Apple trees set many more fruit than desired, requiring a crop load adjustment to achieve acceptable fruit size in the season and an adequate return bloom, thus avoiding biennial bearing. Thus, the aim of this study was to evaluate the effect of different plant growth regulators as 6-benzyladenine (6-BA) and naphthaleneacetic acid (NAA) sprays and lime sulfur (LS) in apple thinning. Two trials were carried out in Uruguay on 2020/2021 growing season in 'Gala Baigent' and 'Rosy Glow' apples, respectively. Productive and quality parameters were evaluated.

ABSTRACT.- Soybean (Glycine max (L.) Merr.), an economically relevant crop, establishes a symbiotic association with rhizobia to obtain nitrogen (N2) from the air by biological nitrogen fixation with important benefits. In Uruguay inoculants formulated with two strains, Bradyrhizobium elkanii U1301 and U1302, are recommended since 1984. Besides that, the study of native-naturalized rhizobia populations is relevant because these strains could compete with applied inoculants and may present a better symbiotic efficiency.

ABSTRACT.- Pear production in Uruguay covers 628 ha being 'Williams' the most planted cultivar. Orchards in Uruguay are managed without the use of pollinizers (parthenocarpy). Pear production in recent years has not been stable, there are many factors that could be influencing, including climatic conditions, low fruit set, among others. The aim of this study was to evaluate the use of plant growth regulators to increase fruit set in 'Williams' pears in orchards with and without pollinizers.

ABSTRACT.- This work aims to contextualize and analyze the potential contribution of pecan to SDG2 under the dual perspective of carbon storage and human nutrition. Particularly, the study focuses on the pecan agroecosystems in the Americas, representing the most important pecan-producing countries (the United States, Mexico, Brazil, Argentina, Uruguay, and Peru). We observed that pecan is a reliable sink for storing atmospheric C and also for quality nuts with high nutritional density. The Americas, hold a population of ca.
