De novo assembly and characterization of leaf transcriptome for the development of functional molecular markers of the extremophile multipurpose tree species Prosopis alba
(2013-10)Background: Prosopis alba (Fabaceae) is an important native tree adapted to arid and semiarid regions of north-western Argentina which is of great value as multipurpose species. Despite its importance, the genomic resources ... -
Nanostructured voltammetric sensor for ultra-trace anabolic drug determination in food safety field
(2013-11)A sensitive electrochemical sensor for clenbuterol (CL) determination in bovine urine samples was designed. This drug was originally developed for the treatment of respiratory pathologies. However, in the livestock industry, ... -
Impacts of population structure and analytical models in genome-wide association studies of complex traits in forest trees: a case study in Eucalyptus globulus
(Plos One, 2013-11-25)The promise of association genetics to identify genes or genomic regions controlling complex traits has generated a flurry of interest. Such phenotype-genotype associations could be useful to accelerate tree breeding cycles, ... -
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
An assessor-specific Bayesian multi-threshold mixed model for analyzing ordered categorical traits in tree breeding
(Springer, 2013-12)Many traits of biological interest in tree breeding are assessed using more than two ordered discrete categories. These scores have a more or less arbitrary and subjective assignment by the assessors, which could lead to ... -
Tecnología de procesos en la generación de biogás a partir de subproductos agrícolas
(2014)Durante la última década hemos sido testigos de un crecimiento exponencial del empleo de diferentes fuentes de biomasa con fines energéticos comerciales. Esta tendencia fuertemente apoyada por el ambientalismo se ha ... -
Identification of single nucleotide polymorphisms [SNPs] at candidate genes involved in abiotic stress in two Prosopis species and hybrids
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2014)Aim of the study: Identify and compare SNPs on candidate genes related to abiotic stress in Prosopis chilensis, Prosopis flexuosa and interspecific hybrids Area of the study: Chaco árido, Argentina. Material and Methods: ... -
Synergy between glyphosate- and cypermethrin-based pesticides during acute exposures in tadpoles of the common South American Toad Rhinella arenarum
(2014)The herbicide glyphosate and the insecticide cypermethrin are key pesticides of modern management in soy and corn cultures. Although these pesticides are likely to co-occur in ephemeral ponds or aquatic systems supporting ... -
Cross transferability of SSR markers to endangered Cedrela species that grow in Argentinean subtropical forests, as a valuable tool for population genetic studies
(Elsevier, 2014-04)Species of Cedrela with a high economic value from Northwest and Northeastern Argentina are severely exploited. This work evaluates whether 51 nuclear SSRs, developed to study phylogenetically close species in the Meliaceae ... -
Carotenoids gene markers for sweetpotato (Ipomoea batatas L. Lam): applications in genetic mapping, diversity evaluation and cross‑species transference
(Springer, 2014-04)Carotenoids play essential biological roles in plants, and genes involved in the carotenoid biosynthesis pathway are evolutionarily conserved. Orange sweetpotato is an important source of β-carotene, a precursor of vitamin ... -
Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
(2014-05)In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x = 13 is the basic chromosome ... -
Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-07)Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This species comprises two varieties, which are distinguished by the indumentum. However, this character is ... -
Density, habitat use, and opportunities for conservation of shorebirds in rice fields in southeastern South America
(Bioone, 2014-08)Worldwide, shorebirds are a major component of rice field avian biodiversity. Rice fields in Argentina and southern Brazil hold large numbers of shorebirds and have been recognized as important areas for migrating or ... -
Crotalaria vespertilio (Papilionoideae, Leguminosae) nuevo registro para el nordeste de Argentina y este de Paraguay
(Sociedad Argentina de Botánica, 2014-09)Crotalaria vespertilio (Papilionoideae, Leguminosae) es citada, descripta e ilustrada por primera vez para NE de Argentina y E de Paraguay. Esta especie es afín a C. paulina, diferenciándose por caracteres florales. Para ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
(2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ... -
Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
(Springer, 2014-12)The translocation of the short arm of rye (Secale cereale L.) chromosome one (1RS) onto wheat (Triticum aestivum L.) chromosome 1B (1RS.1BL) is used in wheat breeding programs worldwide due to its positive effect on yield, ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
