Fine mapping of LrSV2, a race-specific adult plant leaf rust resistance gene on wheat chromosome 3BS
(Springer, 2014-05)Three leaf rust resistance genes were identified in the durable leaf rust resistant Argentinean wheat variety Sinvalocho MA: the seedling resistance gene Lr3 on distal 6BL and two adult plant resistance genes, LrSV1 and ... -
Prediction of aquaporin function by integrating evolutionary and functional analyses
(Springer, 2014-02)Aquaporins (AQPs) are a family of channel proteins, which transport water and/or small solutes across cell membranes. AQPs are present in Bacteria, Eukarya, and Archaea. The classical AQP evolution paradigm explains the ... -
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ... -
Single nucleotide polymorphisms in candidate genes associated with milk yield in Argentinean Holstein and Holstein x Jersey cows
(2018-12)Research on loci influencing milk production traits of dairy cattle is one of the main topics of investigation in livestock. Many genomic regions and polymorphisms associated with dairy production have been reported ... -
Identification and characterization of Pythium graminicola, causal agent of kikuyu yellows in Argentina
(Springer, 2017-08)Kikuyu grass (Pennisetum clandestinum) is a perennial plant that belongs to the Poaceae family. In Argentina, it is used in warm areas as tropical pasture, forage and grass in gardens and sports fields. Species of Pythium ... -
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, ... -
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 ... -
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 ... -
Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia
(BMC Plant Biology, 2014-09-17)Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ... -
Silencing of the glutathione biosynthetic pathway inhibits somatic embryogenesis in wheat
(Springer, 2013-02)Somatic embryogenesis in scutella of wheat (Triticum aestivum L.) is a well documented phenomenon and it has been shown through transcriptome analysis that genes involved in antioxidant responses, particularly in glutathione ... -
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 ... -
Microsatellite markers from the ‘South American fruit fly’ Anastrepha fraterculusa: valuable tool for population genetic analysis and SIT applications
(BioMed Central, 2014-12-01)Background: Anastrepha fraterculus Wiedemann is a horticultural pest which causes significant economic losses in the fruit-producing areas of the American continent and limits the access of products to international markets. ... -
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 ... -
Plant growth-promoting bacterium Pseudomonas fluorescens FR1 secrets a novel type of extracellular polyhydroxybutyrate polymerase involved in abiotic stress response in plants
(Springer, 2018)Objectives Identification of novel microbial factors contributing to plant protection against abiotic stress. Results The genome of plant growth-promoting bacterium Pseudomonas fluorescens FR1 contains a short mobile ... -
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 ... -
Dynamics of genetic variability in Anastrepha fraterculus (Diptera: Tephritidae) during adaptation to laboratory rearing conditions
