En este trabajo se realizaron experimentos ... -
Allele mining in the Argentine public maize inbred line collection of two paralogous genes encoding NAC domains
(Springer Nature, 2017-01)NAC proteins are plant transcription factors involved in biotic and abiotic stress responses, with conserved sub-domain motifs. To our knowledge, no diversity studies have been carried out at the nucleotide level of candidate ... -
Amino acid composition of soybean seeds as affected by climatic variables
(Empresa Brasileira de Pesquisa Agropecuária (Embrapa), 2011-09-12)The objective of this work was to perform a quantitative analysis of the amino acid composition of soybean seeds as affected by climatic variables during seed filling. Amino acids were determined from seed samples taken ... -

Antibody detection against Kunitz-type protein in Fasciola hepatica experimentally infected sheep using enzyme-linked immunosorbent assay (ELISA)
(Taylor & Francis, 2023-11-14)Fasciolosis is a parasitic disease considered as emerging and neglected by the WHO. Sheep are highly susceptible to this disease, and affected flocks experience decreased productivity due to increased mortality, and the ... -
Are all edges equal? Microclimatic conditions, geographical orientation and biological implications in a fragmented forest
(Elsevier, 2019-08-01)In fragmented forests the edges experience changes in microclimatic conditions, which are referred to as “abiotic edge effect”, and differ according to geographical orientation and season. These microclimatic changes could ... -
Attainable yield and soil texture as drivers of maize response to nitrogen : A synthesis analysis for Argentina
(Elsevier, 2021-09)The most widely used approach for prescribing fertilizer nitrogen (N) recommendations in maize (Zea Mays L.) in Argentina is based on the relationship between grain yield and the available N (kg N ha−1), calculated as the ... -
