Coexistence between two fruit fly species is supported by the different strength of intra- and interspecific competition
(2018-04)1. Unravelling the strength and modes of interspecific interactions between resident and introduced species is necessary in order to understand the basis of their coexistence or the displacement of the former by the ... -
Adh1 first intron polymorphisms in Argentinean populations of Ceratitis capitata
(2010-07)DNA size polymorphisms were utilized in a study of 24 natural populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae) from Argentina. The first intron of alcohol dehydrogenase 1 gene (Adh1) was amplified using ... -
Genome-wide scan for commons SNPs affecting bovine leukemia virus infection level in dairy cattle
(2018-02-13)Background: Bovine leukemia virus (BLV) infection is omnipresent in dairy herds causing direct economic losses due to trade restrictions and lymphosarcoma-related deaths. Milk production drops and increase in the culling ... -
A novel source of cytoplasmic male sterility in Calibrachoa pubescens
(2017)Calibrachoa pubescens is a species native from the south of Brazil, Uruguay and northeast Argentina. An accession identified as 7.3.1.1 was collected at San Martín Department in Corrientes Province, Argentina and is included ... -
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 ... -
A novel association of BoLA DRB3 alleles in BLV infected cattle with different proviral loads
(2017)Bovine leukemia virus (BLV) is associated with the most common neoplastic disease of cattle. BLV has a silent dissemination in the herd due to infected cell exchange, thus the concentration of BLV-infected cells in blood ... -
Stable symbiotic nitrogen fixation under water-deficit field conditions by a stress-tolerant alfalfa microsymbiont and its complete genome sequence : Short communication
(2017-12)We here characterized the stress-tolerant alfalfa microsymbiont Sinorhizobium meliloti B401. B401-treated plants showed high nitrogen fixation rates under humid and semiarid environments. The production of glycine betaine ... -
Microevolution rather than large genome divergence determines the effectiveness of legume–rhizobia symbiotic interaction under field conditions
(2017-08)Despite the vast screening for natural nitrogenfixing isolates by public and private consortia, no significant progresses in the production of improved nitrogenfixing inoculants for alfalfa production have been made in the ... -
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 ... -
Engineering Pseudomonas protegens Pf-5 for nitrogen fixation and its application to improve plant growth under nitrogen-deficient conditions
(2013-05-13)Nitrogen is the second most critical factor for crop production after water. In this study, the beneficial rhizobacterium Pseudomonas protegens Pf-5 was genetically modified to fix nitrogen using the genes encoding the ... -
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 ... -
Genetic diversity in a world germplasm collection of tall fescue
(2013)Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ... -
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. ... -
Genetic characterisation of PPARG, CEBPA and RXRA, and their influence on meat quality traits in cattle
(2016)Antecedentes: peroxisoma receptor gamma activado por el proliferador (PPARg), unión a CCAAT / potenciador de la proteína alfa (CEBPA) y el receptor de retinoides X alfa (RXRA) son factores de transcripción nuclear que ... -
Effect of polyploidization in the production of essential oils in Lippia integrifolia
(2016-03)Consumption of medicinal and aromatic plants is widespread and increasing worldwide. Yet, harvesting from the wild, the main source of raw material in developing countries, is causing loss of genetic diversity and habitat ... -
Patterns of resource distribution among conspecific larvae in two fruit fly species : Anastrepha fraterculus and Ceratitis capitata (diptera: tephritidae)
(2016)1 Anastrepha fraterculus (Diptera: Tephritidae) and Ceratitis capitata (Diptera: Tephritidae) are fruit fly pests whose larvae are frequently found sharing the same fruit with conspecifics. Because larvae are incapable of ... -

Minimizing the time and cost of production of transgenic alfalfa libraries using the highly efficient completely sequenced vector pPZP200BAR
(2016)Alfalfa is the most important forage legume worldwide. However, similar to other minor forage crops, it is usually harvested along with weeds, which decrease its nutrient quality and thus reduce its high value in the ... -
Water deficit stress tolerance in maize conferred by expression of an anisopentenyltransferase (IPT) gene driven by a stress- and maturation-induced promoter
