Argentina’s local crop biotechnology developments: why have they not reached the market yet?
(Frontiers Media, 2020-04)Plant biotechnology in Argentina started at the end of the 1980s, leading to the development of numerous research groups in public institutions and, a decade later, to some local private initiatives. The numerous scientific ... -
Association of TNF-α gene promoter region polymorphisms in bovine leukemia virus (BLV)-infected cattle with different proviral loads
(2015-08)Tumor necrosis factor alpha (TNF-α) is a pleiotropic cytokine involved in the immune response against viral and other infections. Its expression levels are affected by a polymorphism in the promoter region of the gene. ... -
Associative learning of visual cues in the fruit fly parasitoid Diachasmimorpha longicaudata : temporal dynamics and potential consequences on females' fitness
(Wiley, 2024-01)Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is a generalist larval-prepupal parasitoid of true fruit flies (Diptera: Tephritidae). During host-seeking, females use visual information to locate the ... -
Bacterially expressed dsRNA induces Varroa destructor gene knockdown by honey bee-mediated oral administration
(Taylor and Francis, 2022-02)The ectoparasite Varroa destructor causes serious losses of Apis mellifera colonies and negatively impacts the beekeeping industry around the world. New control methods have been proposed based on the RNA interference ... -
Beyond arabidopsis: differential UV-B response mediated by UVR8 in diverse species
(Frontiers Media, 2019-06)Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated ... -
La biotecnología como herramienta para la conservación y el cuidado de la biodiversidad de las especies aromático-medicinal nativas
(2018-04)En este capítulo se tomaron 11 especies diferentes de PAMs y se muestra una revisión de sus usos populares, sus potenciales aplicaciones, sus correspondientes estados de conservación, y el grado de aplicación de las ... -
BOLA-DRB3 gene polymorphisms influence bovine leukaemia virus infection levels in Holstein and Holstein × Jersey crossbreed dairy cattle
(2017-05)Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of ... -
Bovine leukemia virus becomes established in dairy herds before the first lactation
(2016)In this work, we studied seven groups of pregnant heifers from a consortium of dairy farms heavily infected with bovine leukemia virus (BLV). ELISA testing showed that the seroprevalence ranges of BLV in heifers between ... -
Canarypox virus expressing infectious bursal disease VP2 protein as immunogen for chickens
(Sociedade Brasileira de Microbiologia, 2014-05)Canarypox viruses (CNPV) carrying the coding sequence of VP2 protein from infectious bursal disease virus (IBDV) were obtained. These viruses were able to express VP2 protein in vitro and to induce IBDV-neutralizing ... -
Candidate Gene Approach for Parasite Resistance in Sheep – Variation in Immune Pathway Genes and Association with Fecal Egg Count
(Plos One, 2014-02-12)Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within ... -
