Loci de caracteres cuantitativos para rasgos reproductivos en bovinos lecheros locales
(Sociedad Argentina de Genética, 2022-10)Introducción: La intensa selección para producción lechera junto con una consideración insuficiente de parámetros de fertilidad y salud, sumado a las correlaciones genéticas antagonistas o cercanas a cero entre caracteres ... -
Long-term maintenance rate fertilisation increases soil bacterial-archaeal community diversity in the subsoil and N-cycling potentials in a humid crop season
(Elsevier, 2024-01)Among agronomical practices, fertilisation greatly influences soil microbial diversity and functionality and severely disturbs the global nitrogen (N) cycle. In this study, we assessed the effect of 16 years of mineral ... -
Longitudinal follow-up of the immunity to SARS-CoV-2 in health care workers in Argentina : persistence of humoral response and neutralizing capacity after Sputnik V vaccination
(American Society for Microbiology, 2023-06)SARS-CoV-2 vaccine protection has encountered waning of immune response and breakthrough infections. The hybrid immune response generated by the combination of vaccination and infection was shown to offer higher and broader ... -
LOV‐domain photoreceptor, encoded in a genomic island, attenuates the virulence of Pseudomonas syringae in light‐exposed Arabidopsis leaves
(Wiley, 2013-10)In Arabidopsis thaliana, light signals modulate the defences against bacteria. Here we show that light perceived by the LOV domain‐regulated two‐component system (Pst–Lov) of Pseudomonas syringae pv. tomato DC3000 (Pst ... -
Machine learning algorithms identified relevant SNPs for milk fat content in cattle
(Sociedad Argentina de Informática, 2021-10)In recent years, machine learning methods have been shown to be efficient in identifying a subset of single nucleotide polymorphisms (SNP) underlying a trait of interest. The aim of this study was the construction of ... -
Macro y micropropagación de peperina de las lomas (Hedeoma multiflorum Benth)
(Ediciones INTA, 2020-07)La extracción intensiva de plantas aromático-medicinales (PAMs) de sus ambientes naturales coloca a muchas especies en una situación de gran vulnerabilidad ecológica. Este es el caso de la “peperina de las lomas” (Hedeoma ... -
Main and epistatic QTL analyses for Sclerotinia Head Rot resistance in sunflower
(PLOS, 2017-12)Sclerotinia Head Rot (SHR), a disease caused by Sclerotinia sclerotiorum, is one of the most limiting factors in sunflower production. In this study, we identified genomic loci associated with resistance to SHR to support ... -
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ... -
Mal de Río Cuarto virus (MRCV) genomic segment S3 codes for the major core capsid protein
(Springer, 2009-06)Mal de Río Cuarto virus (MRCV) is a newly described species of the genus Fijivirus, family Reoviridae. Compared with other plant-infecting genus of the family, the function and localization of MRCV and other Fijivirus ... -
Mal de Río Cuarto virus infection causes hormone imbalance and sugar accumulation in wheat leaves
(BMC, 2019-03)Background; Mal de Río Cuarto virus (MRCV) infects several monocotyledonous species including maize and wheat. Infected plants show shortened internodes, partial sterility, increased tillering and reduced root length. To ... -
Mal de Río Cuarto Virus infection triggers the production of distinctive viral-derived siRNA profiles in wheat and Its planthopper vector
(2017)Plant reoviruses are able to multiply in gramineae plants and delphacid vectors encountering different defense strategies with unique features. This study aims to comparatively assess alterations of small RNA (sRNA) ... -
Male Sexual Behavior and Pheromone Emission Is Enhanced by Exposure to Guava Fruit Volatiles in Anastrepha fraterculus
(Plos One, 2015-04)Background: Plant chemicals can affect reproductive strategies of tephritid fruit flies by influencing sex pheromone communication and increasing male mating competitiveness. Objective and Methodology: We explored whether ... -
Male sexual enhancement after methoprene treatment in Anastrepha fraterculus (Diptera: Tephritidae) : a sustained response that does not fade away after sexual maturation
(2017)The juvenile hormone (JH) of insects triggers physiological changes related to reproduction in adults of both sexes. Methoprene is a sesquiterpene with some effects that are analogous to those of JH. Treatments with ... -
Male–female separation with a genetic sexing strain of Medfly, Ceratitis capitata, based on the gene sw (slow)
(lsteg Scientific Publications, 2004)The rate of development of the Medfly, Ceratitis capitata, slows down in the presence of mutation slow, sw. Separation of fast-developing males from slow-developing females is possible when this locus on chromosome 2 is ... -
