Este año la Jornada de Agrobiotecnología INIA tuvo como foco el combate a la mosca de la bichera. Atendiendo a la relevancia del tema, participaron en la organización de la jornada:MGAP, INAC, IPA, SUL y el Institut Pasteur de Montevideo.

El género Paspalum comprende un alto número de especies que aportan buena producción y calidad como forrajeras durante la época estival. En un contexto de cambio climático y ante la oportunidad de aumentar el uso de especies C4 como forrajeras, INIA se encuentra trabajando sobre estrategias para generar resistencia a la "enfermedad azucarada" y así favorecer la formación y desarrollo de semilla en especies de este género.
Rice blast caused by Pyricularia oryzae is a major rice disease worldwide. Despite the detailed knowledge on major resistance genes available to date, little is known about how these genes interact with quantitative blast resistance loci and with the genetic background. Knowledge on these interactions is crucial for assessing the usefulness of introgressed resistance loci in breeding germplasm. Our goal was to identify quantitative trait loci (QTL) for blast resistance in rice breeding populations and to describe how they interact among each other and with the genetic background.
Soil microbial communities play critical roles in maintaining natural ecosystems such as the Campos biome grasslands of southern South America. These grasslands are characterized by a high diversity of soils, low available phosphorus (P) and limited water holding capacity. This work aimed to describe prokaryotic communities associated with different soil types and to examine the relationship among these soil communities, the parent material and the soil nutrient status. Five Uruguayan soils with different parent material and nutrient status, under natural grasslands, were compared.
ABSTRACT. BACKGROUND AND AIMS:The Mediterranean-type forest of central Chile is considered a 'biodiversity hotspot' and a relic of a wider ancient distribution produced by past climatic oscillations. Nothofagus macrocarpa, commonly known as 'roble de Santiago', is a threatened palaeoendemic of this forest, poorly represented in the protected area system. This tree has been repeatedly misidentified as the sister species N. obliqua, which has affected its recognition and protection. Only a few populations of N.

ABSTRACT. Pear is one of the most important temperate fruit crops. To propagate a reasonable number of plants in the shortest possible time, different in vitro multiplication systems were evaluated:solid media and temporary immersion bioreactors with two different cultivation media in each system.
