(FundaVet, 2019-06)Los glicosilfosfatidilinositoles (GPIs) se encuentran en abundancia en la superficie de protozoos parásitos como glicolípidos libres y como anclas de proteínas de superficie a la membrana plasmática. Se ha demostrado que ... -
Expressing the sunflower transcription factor HaHB11 in maize improves waterlogging and defoliation tolerance
(Oxford University Press, 2022-05)The sunflower (Helianthus annuus) transcription factor HaHB11 (H. annuus Homeobox 11) belongs to the homeodomain-leucine zipper family and confers improved yield to maize (Zea mays) hybrids (HiII × B73) and lines. Here we ... -
Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Expression and mapping of anthocyanin biosynthesis genes in carrot
(2013-07)Anthocyanin gene expression has been extensively studied in leaves, fruits and flowers of numerous plants. Little, however, is known about anthocyanin accumulation in roots of carrots or other species. We quantified ... -
Expression and purification of recombinant feline interferon in the baculovirus-insect larvae system
(2014-06)Feline interferons (FeIFNs) are cytokines with antiviral, antitumor and immunomodulatory functions used as therapeutic agents in a variety of veterinary diseases. In this work, FeIFN-α7 and FeIFN-α7xArg containing eight ... -
Expression of animal anti-apoptotic gene ced-9 enhances tolerance during Glycine max L.– Bradyrhizobium japonicum interaction under saline stress but reduces nodule formation
(2014-07-27)The mechanisms by which the expression of animal cell death suppressors in economically important plants conferred enhanced stress tolerance are not fully understood. In the present work, the effect of expression of animal ... -
Expression of apoptosis-related genes at different stages of BoHV-1 and 5 infection of bovine neural tissue
(Elsevier, 2022-11)Bovine alphaherpesviruses (BoHV) 1 and 5 share many genetic and structural characteristics; however, they differ in their ability to cause encephalitis. Previous research suggests that this difference might be caused by a ... -
Expression of grapevine AINTEGUMENTA-like genes is associated with variation in ovary and berry size
(2016-05)Fruit size is a highly important trait for most fruit and vegetable crops. This trait has been a main selection target and could be involved in divergent selection processes leading to the differentiation between modern ... -
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
(Springer Nature, 2020-10-07)Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ... -
Expression profile of genes as indicators of developmental competence and quality of in vitro fertilization and somatic cell nuclear transfer bovine embryos
(Plos One, 2014-09)Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags ... -
Expression profile of transcripts encoding cell wall remodelling proteins in tomato fruit cv. Micro-Tom subjected to 15°C storage
(2013)To extend fruit market life, tomatoes are harvested before red ripe and kept at temperatures below optimum (20°C). In this work, Micro-Tom tomatoes stored at 20°C (normal ripening) were compared with those stored at 15°C ... -
Expression-based analysis of genes related to single nucleotide polymorphism hits associated with bovine leukemia virus proviral load in Argentinean dairy cattle
(Elsevier, 2021-02)In dairy cattle infected with bovine leukemia virus (BLV), the proviral load (PVL) level is directly related to the viral transmission from infected animals to their healthy herdmates. Two contrasting phenotypic groups can ... -
