La ineficiencia reproductiva ... -
Morir en soledad: la terrible situación de las personas que fallecen por COVID-19 y el dolor de sus familiares en un contexto de desborde del sistema de salud
(Sociedad Argentina de Medicina, 2020-09)La Organización Mundial de la Salud declaró la pandemia de covid-19 el 11 de marzo de 2020. El coronavirus pandémico afecta a todo el mundo desde que se identificó en diciembre de 2019 en Wuhan, China. La pandemia causó ... -
Morphological and genetic diversity of maize landraces along an altitudinal gradient in the Southern Andes
(BioRxiv, 2022-07)Maize (Zea mays ssp. mays) is a major cereal crop worldwide and is traditionally or commercially cultivated almost all over the Americas. The northwestern region of Argentina (NWA) constitutes one of the main diversity ... -
Morphological and molecular evidence for a new species of Pseudanisakis Layman & Borovkova, 1926 (Nematoda: Ascaridida), parasitizing Rajiformes in southern Southwest Atlantic waters
(2017-07)Pseudanisakis argentinensis n. sp. is proposed to accommodate parasitic nematodes found in six skate species (Rajidae and Arhynchobatidae) examined from southern Southwest Atlantic waters. The new species differs from its ... -
Morphometric and genetic characterization as tools for selection of Apis mellifera (Hymenoptera: Apidae) stocks in an area of natural hybridization in Argentina
(Frontiers Media, 2023-01)Beekeepers around the world select bees’ characteristics that facilitate and favor production. In regions where hybridization among lineages is taking place, this selection is a challenge, given that these regions are ... -
Moscas blancas y enemigos naturales asociados al cultivo de naranja bajo dos tipos de manejo sanitario en San Pedro, provincia de Buenos Aires = Whiteflies and natural enemies on orange crops under two types of sanitary management in San Pedro, Buenos Aires province
(Sociedad Entomológica Argentina, 2017)Las moscas blancas (Hemiptera: Aleyrodidae) son importantes plagas que afectan al género Citrus. En este trabajo se identificaron las especies presentes en naranjos de San Pedro (provincia de Buenos Aires) y se analizó su ... -
Moscas minadoras del girasol y sus enemigos naturales
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-08)Las “moscas minadoras” se caracterizan por excavar túneles (“minas”) en el interior de las hojas, consumiendo el mesófilo y dejando intacta la epidermis foliar o, al menos, su pared externa. Hay especies cuyas larvas, en ... -
Mouse model as an efficacy test for foot‐and‐mouth disease vaccines
(Wiley, 2020-04)Protection against foot‐and‐mouth disease virus (FMDV) has been linked to the development of a humoral response. In Argentina, the official control tests for assessing the potency of FMD vaccines are protection against ... -
mRNA biogenesis-related helicase eIF4AIII from Arabidopsis thaliana is an important factor for abiotic stress adaptation
(2016)Similar to other plant species, Arabidopsis has a huge repertoire of predicted helicases, including the eIF4AIII factor, a putative component of the exon junction complex related to mRNA biogenesis. In this article, we ... -
Multiomics analyses reveal the roles of the ASR1 transcription factor in tomato fruits
(Oxford University Press, 2021-09)The transcription factor ASR1 (ABA, STRESS, RIPENING 1) plays multiple roles in plant responses to abiotic stresses as well as being involved in the regulation of central metabolism in several plant species. However, despite ... -
