Abstract. Rice (Oryza sativa L.) is one of the most important staple food crops in the world; however, there has recently been a shift in consumer demand for higher grain quality. Therefore, understanding the genetic architecture of grain quality has become a key objective of rice breeding programs. Genomewide association studies (GWAS) using large diversity panels have successfully identified genomic regions associated with complex traits in diverse crop species.

ABSTRACT. The widespread use of artificial insemination has allowed the expansion of genetic progress. However, it also brought consequences such as the expansion of lethal hereditary diseases and the increase in inbreeding. The object of this study was to establish a fast and sensitive molecular assay to detect bovine leukocyte adhesion deficiency (BLAD) and deficiency of uridine monophosphate synthase (DUMPS) carriers in Uruguayan Holstein cattle by means of high resolution melting (HRM) curve analysis.

ABSTRACT. One of the main limitations of rice yield in regions of high productive performance is the light-use efficiency (LUE). LUE can be determined at the whole-plant level or at the photosynthetic apparatus level (quantum yield). Both vary according to the intensity and spectral quality of light. The aim of this study was to analyze the cultivar dependence regarding LUE at the plant level and quantum yield using four rice cultivars and four light environments.

La soja (Glycine max L.) es uno de los cuatro cultivos de mayor importancia a nivel mundial. El objetivo general del proyecto fue desarrollar las capacidades a nivel nacional para incluir la ingeniería genética en el repertorio de técnicas útiles al mejoramiento genético del cultivo de soja. En particular, el proyecto tuvo como objetivos desarrollar las capacidades en el país para transformar soja y generar intragénicos de esta especie que incorporen genes involucrados en la tolerancia a sequía.
