ABSTRACT. - Background:Diaporthe caulivora is a fungal pathogen causing stem canker in soybean worldwide. The generation of genomic and transcriptomic information of this ascomycete, together with a comparative genomic approach with other pathogens of this genus, will contribute to get insights into the molecular basis of pathogenicity strategies used by D. caulivora and other Diaporthe species. Results:In the present work, the nuclear genome of D. caulivora isolate (D57) was resolved, and a comprehensive annotation based on gene expression and genomic analysis is provided.

ABSTRACT. - Drought limits crop productivity and reduces yield stability. Drought tolerance as a selection criterion in breeding programs requires the development of high-throughput, precise, and low-cost phenotyping strategies. We developed a mathematical model, based on biological approaches, for evaluating soybean plants? response to drought under controlled growth conditions. The model describes the kinetics of water consumption of a plant pot substrate system (PPS) with low sampling requirements.

Desarrollar tecnologías para la producción sostenible de alimentos saludables, que diversifiquen la dieta de los uruguayos y contribuyan a la exportación, es un desafío que tienen los Programas de Investigación en Producción Citrícola, Frutícola y Hortícola ?que integran el Sistema Vegetal Intensivo?.

RESUMEN - En Uruguay el diagnóstico de rutina de Neospora caninum se realiza fundamentalmente por estudios histopatológicos de los fetos abortados complementando esta información con resultados deserología y/o Inmunohistoquímica (IHQ). El objetivo de este estudio fue estandarizar un protocolo de amplificación de secuencias mediante PCR (polymerase chain reaction) para la detección de Neospora caninum en órganos de fetos abortados espontáneamente en bovinos para su incorporación a la rutina diagnostica.

ABSTRACT - Background:The phytopatogen Claviceps paspali is the causal agent of Ergot disease in Paspalum spp., which includes highly productive forage grasses such as P. dilatatum. This disease impacts dairy and beef production by affecting seed quality and producing mycotoxins that can affect performance in feeding animals. The molecular basis of pathogenicity of C. paspali remains unknown, which makes it more difficult to find solutions for this problem. Secreted proteins are related to fungi virulence and can manipulate plant immunity acting on different subcellular localizations.
