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 ... -
Characterization and comparative analysis of the genome of Puccinia sorghi Schwein, the causal agent of maize common rust
(Elsevier, 2018-03)Rust fungi are one of the most devastating pathogens of crop plants. The biotrophic fungus Puccinia sorghi Schwein (Ps) is responsible for maize common rust, an endemic disease of maize (Zea mays L.) in Argentina that ... -
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 ... -
Maximizing the expression of transgenic traits into elite alfalfa germplasm using a supertransgene configuration in heterozygous conditions
(2018-05)Numerous species of legumes, including alfalfa, are critical factors for agroecosystems due to their ability to grow without nitrogen fertilizers derived from non-renewable fossil fuels, their contribution of organic ... -
High-quality forage production under salinity by using a salt-tolerant AtNXH1-expressing transgenic alfalfa combined with a natural stress-resistant nitrogen-fixing bacterium
(Elsevier, 2018-06)Alfalfa, usually known as the “Queen of Forages”, is the main source of vegetable protein to meat and milk production systems worldwide. This legume is extremely rich in proteins due to its highly efficient symbiotic ... -
Caracterización del proceso de fabricación de macroporos sobre sustrato de silicio por método electroquímico = Characterization of fabrication process of micropores on silicon substrate by electrochemical method
(Universidade Federal do Rio de Janeiro, 2018-07)En el presente trabajo se estudió el proceso de fabricación de una serie de macroporos sobre obleas de silicio cristalino mediante la técnica wet etching. Se evaluó la incidencia de distintos factores como el voltaje, la ... -
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
(Springer, 2018-08)A complementary gene to LrSV2 for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked to Lr12 / 31. LrSV2 is a race-specific adult plant leaf rust (Puccinia triticina) resistance ... -
Absence of the nitrous oxide reductase gene cluster in commercial alfalfa inoculants is probably due to the extensive loss of genes during rhizobial domestication
(Springer, 2018-08)As other legume crops, alfalfa cultivation increases the emission of the greenhouse gas nitrous oxide (N2O). Since legumesymbiotic nitrogen-fixing bacteria play a crucial role in this emission, it is important to understand ... -
Traditional uses, conservation status and biotechnological advances for a group of aromatic / medicinal native plants from America = Usos tradicionales, estado de conservación y avances biotecnológicos para un grupo de plantas aromáticas / medicinales nativas de América
(Universidad de Santiago de Chile, 2018-09)Medicinal and aromatic plants are biologically and economically valuable species because of their intrinsic value as plants, ability to produce secondary metabolites, possible use in the pharmaceutical and food industries, ... -
Plant chemicals and the sexual behavior of male tephritid fruit flies
(Oxford University Press, 2018-09)Plant compounds affect insects in many different ways. In addition to being a food source, plants also contain secondary metabolites that may have positive and negative impacts on insects. The influence of these compounds ... -
Plant growth-promoting genes can switch to be virulence factors via horizontal gene transfer
(Springer, 2018-10)There are increasing evidences that horizontal gene transfer (HGT) is a critical mechanism of bacterial evolution, while its complete impact remains unclear. A main constraint of HGT effects on microbial evolution seems ... -
The ammonium channel NOD26 is the evolutionary innovation that drives the emergence, consolidation, and dissemination of nitrogen-fixing symbiosis in angiosperms
(Springer, 2018-10)Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ... -
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
(Elsevier, 2018-11)After gene duplication, paralogous genes evolve independently, and consequently, the new proteins encoded by these duplicated genes are exposed to changes in their subcellular location. Although there are increasing evidence ... -
In vivo and in vitro propagation of “macela”: a medicinal-aromatic native plant with ornamental potential
(Sociedade Brasileira de Floricultura e Plantas Ornmentais, 2018-12)Achyrocline satureioides is a shrub native from South America. In popular medicine it is used in infusions such as digestive, carminative, antispasmodic, eupeptic and emmenagogue. However, its main use is as an ingredient ... -
Single nucleotide polymorphisms in candidate genes associated with milk yield in Argentinean Holstein and Holstein x Jersey cows
