In vitro propagation of Lippia integrifolia (Griseb.) Hier. and detection of genetic instability through ISSR markers of in vitro-cultured plants.
(2016)Aromatic and medicinal plants have been traditionally harvested from the wild and, in Argentina, they have been exploited without any major limitation. In vitro plant propagation is an easy and inexpensive method to obtain ... -
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ... -
Development of a construct-based risk assessment framework for genetic engineered crops
(2016)Experience gained in the risk assessment (RA) of genetically engineered (GE) crops since their first experimental introductions in the early nineties, has increased the level of familiarity with these breeding methodologies ... -
Cytogenetic analysis of the South American fruit fly Anastrepha fraterculus (diptera:tephritidae) species complex : construction of detailed photographic polytene chromosome maps of the Argentinian af. sp.1 member
(2016)Genetic and cytogenetic studies constitute a significant basis for understanding the biology of insect pests and the design and the construction of genetic tools for biological control strategies. Anastrepha fraterculus ... -
Ancestry analysis of locally adapted crespa goats from southernmost Brazil
(2016)Crespa goats are phenotypically similar to the Angora breed, and are traditionally reared in small, low-tech farms in southernmost Brazil. Whether they represent degenerated remnants of pure Angora goats or result from ... -
Plastome mutations and recombination events in barley chloroplast mutator seedlings
(2016)The barley chloroplast mutator (cpm) is an allele of a nuclear gene that when homozygous induces several types of cytoplasmically inherited chlorophyll deficiencies. In this work, a plastome Targeting Induced Local Lesions ... -
mRNA biogenesis-related helicase eIF4AIII from Arabidopsis thaliana is an important factor for abiotic stress adaptation
(2016)Similar to other plant species, Arabidopsis has a huge repertoire of predicted helicases, including the eIF4AIII factor, a putative component of the exon junction complex related to mRNA biogenesis. In this article, we ... -
Genetic diversity and population structure in South African, French and Argentinian angora goats from genome-wide snp data
(2016)The Angora goat populations in Argentina (AR), France (FR) and South Africa (SA) have been kept geographically and genetically distinct. Due to country-specific selection and breeding strategies, there is a need to ... -
Pip water transport and its pH dependence are regulated by tetramer stoichiometry
(2016)Many plasma membrane channels form oligomeric assemblies, and heterooligomerization has been described as a distinctive feature of some protein families. In the particular case of plant plasma membrane aquaporins (PIPs), ... -
Pollen aquaporins : the solute factor
(2016)In the recent years, the biophysical properties and presumed physiological role of aquaporins (AQPs) have been expanded to specialized cells where water and solute exchange are crucial traits. Complex but unique processes ... -
Pollen-specific aquaporins NIP4;1 and NIP4;2 are required for pollen development and pollination in Arabidopsis thaliana
(2016)In flowers with dry stigmas, pollen development, pollination, and pollen tube growth require spatial and temporal regulation of water and nutrient transport. To better understand the molecular mechanisms involved in ... -
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 ... -
Transcriptome profiling of Diachasmimorpha longicaudata towards useful molecular tools for population management
(2016)Background: Diachasmimorpha longicaudata (Hymenoptera: Braconidae) is a solitary parasitoid of Tephritidae (Diptera) fruit flies of economic importance currently being mass-reared in bio-factories and successfully used ... -
Effects of superparasitism on immature and adult stages of Diachasmimorpha longicaudata Ashmead (Hymenoptera: Braconidae) reared on Ceratitis capitata Wiedemann (Diptera: Tephritidae)
(2017)The optimal use of available host by parasitoid insects should be favoured by natural selection. For solitary parasitoids, superparasitism (i.e. the egg-laying of several eggs/host) may represent a detrimental phenomenon ... -
The genetic diversity of wild rescuegrass is associated with precipitation levels
(Springer, 2014-04-27)The genus Bromus belongs to the family Poaceae, contains over 160 annual and perennial species of grasses, varying in ploidy level from diploid (2n = 14) to dodecaploid (2n = 70) (Fortune et al. 2008). One of the most ... -
Genome-wide identification of the mutation uderlying fleece variation and discriminating ancestral hairy species from modern woolly sheep
(Oxford university press, 2017-07)The composition and structure of fleece variation observedin mammals is a consequence of a strong selective pressure for fiber production after domestication. In sheep, fleece variation discriminates ancestral species ... -
Virulence characterization and identification of maize lines resistant to Puccinia sorghi Schwein. Present in the argentine corn belt region
(2016-04)Puccinia sorghi Schwein., the causal agent of maize common rust, is an endemic disease in the Argentine Corn Belt region. Virulence surveys of the pathogen population within the region have not been performed; thus, the ... -
Spermatogenesis in the parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae)
(2017)The study of spermatogenesis in Hymenoptera is limited to few taxa due to limitations to access the material in the right stage for analysis. The information available up to now states that the gametogenesis in males ... -
Validation of housekeeping genes for qPCR in maize during water deficit stress conditions at flowering time
(2017)Plant stress studies are increasingly being based on gene expression. The analysis of gene expression requires sensitive, precise, and replicable measurements for specific mRNA sequences. Real-time RT-PCR is nowadays the ... -
