The Platform of Microbial Products for Agriculture at INIA Las Brujas has emphasized the role of microorganisms in the biocontrol of plant pests and diseases, and in nitrogen and phosphorus plant nutrition.
ABSTRACT. The objective of this study was the optimization and implementation of a reliable and economical molecular screening method for the detection of the mutant allele of CVM (complex vertebral malformation, c.559G>T, SLC35A3) by HRM analysis, as well as analyzing its existence in a representative sample of Holstein cows from the Milk Genomic DNA Bank of Uruguay. The optimization of the HRM methodology in the RotorGene?
En Uruguay, Argentina y el sur de Brasil se distribuyen parientes silvestres de la papa como Solanum commersonii, S. malmeanum y S. chacoense. Presentan resistencia a varios estreses bióticos y abióticos, gran adaptabilidad a nuestros ambientes y amplia diversidad genética. Este proyecto busca, en paralelo con un proyecto de Embrapa Clima Temperado en Brasil, caracterizar genética y morfológicamente los parientes silvestres de la papa de Uruguay y sur de Brasil y construir colecciones núcleo.
ABSTRACT. The photosynthesis process is determined by the intensity level and spectral quality of the light; therefore, leaves need to adapt to a changing environment. The incident energy absorbed can exceed the sink capability of the photosystems, and, in this context, photoinhibition may occur in both photosystem II (PSII) and photosystem I (PSI). Quantum yield parameters analyses reveal how the energy is managed.
Las relaciones que se establecen entre bacterias del suelo pueden ser de cooperación o de antagonismo, y en el medio existe un abanico de posibilidades. Este trabajo completa un primer panorama de la relación entre origen, antagonismo y señalización entre Streptomyces del suelo.
En el suelo ocurren interacciones entre sus diversos componentes físicos, químicos y biológicos. El término salud del suelo se refiere a las dinámicas biológicas que ocurren en él, incluyendo la capacidad de las comunidades microbianas de proteger a los cultivos de enfermedades.
Diariamente se divulga información de precios de distintas categorías de ganado bovino y ovino a través de diversos medios de prensa. Ya sea que los datos provengan de un remate - tradicional o por pantalla - o de resúmenes de estadísticas semanales o períodos mayores, lo que se publican son promedios y, en todo caso, rangos de precios (mínimo y máximo). Existe una variabilidad, a veces muy marcada, en los valores de los ganados comercializados, no sólo en fechas diferentes sino dentro de un mismo local de remate en un día en particular.
ABSTRACT. We examined the effect of lipid content in the diet on the transcriptome of the Longissimus dorsi muscle in pigs. Our objective was to examine changes at the molecular level affecting economically relevant meat quality characteristics such as intramuscular fat deposition and fatty acid profile. The treatments consisted of isoproteic and isoenergetic diets with differing lipid contents due to addition of rice bran. The control diet (T0) was a normal basic diet and the test diet (T15) had 15% rice bran.
ABSTRACT. We have investigated the origin of swine breeds through the joint analysis of mitochondrial, microsatellite, and Y-chromosome polymorphisms in a sample of pigs and wild boars with a worldwide distribution. Genetic differentiation between pigs and wild boars was remarkably weak, likely as a consequence of a sustained gene flow between both populations.
ABSTRACT. Prosopis strombulifera (Lam.) Benth. is a spiny shrub with the maximum tolerance limits reported for halophytic plants. This species is frequently found in the salinized areas in south-western of Córdoba and San Luis provinces, Argentina. Little is known about the genetic diversity within this species in a native population. Genetic diversity in 60 plants of P. strombulifera in south-western San Luis was investigated using AFLP analysis. Polymorphism was found among the samples tested.
