Molecular identification of Azospirillum spp.: limitations of 16S rRNA and qualities of rpoD as genetic markers
(2017)
Since their discovery, plant-growth promoting rhizobacteria from the genus Azospirillum have been sub-jected to intensive research due to their biotechnological potential as crop inoculants. Phylogeneticanalysis of ...
Impact of extracellular nucleic acids from lactic acid bacteria on qPCR and RT-qPCR results in dairy matrices : implications for defining molecular markers of cell integrity
(2017-07)
In this study, we evaluated whether quantitative PCR (qPCR) and reverse transcription-qPCR (RT-qPCR) results could be affected by extracellular (free) DNA or RNA, respectively, obtained either from isolated bacteria or ...
Detection of Plasmopara halstedii in sunflower seeds: A case study using molecular testing.
(Elsevier, 2021-05-06)
Plasmopara halstedii (Farl.) Berl. & De Toni causing downy mildew of sunflower is responsible for considerable economic losses worldwide. Because P. halstedii can be seed-transmitted, monitoring of seeds for pathogen ...
Characterisation and transferability of transcriptomic microsatellite markers for Nothofagus species
(2017-07)
Discriminant molecular markers are required for research on population genetics, as well as evolutionary studies involving identification of hybrids and parental species, or detection of the genome regions under selection. ...
SSRs, SNPs and DArTs comparison on estimation of relatedness and genetic parameters’ precision from a small half-sib sample population of eucalyptus grandis
(2016)
Simple sequence repeats (SSR) are the most widely used molecular markers for relatedness inference due to their multi-allelic nature and high informativeness. However, there is a growing trend toward using high-throughput ...
Antifungal susceptibility profile and molecular identification of Cyp51C mutations in clinical and environmental isolates of Aspergillus flavus from Argentina
(Wiley, 2020-10)
Background: The emergence of azole resistance in non‐fumigatus Aspergillus strains is on the raise.
Objectives: To study the susceptibility profiles and the molecular mechanisms of azole resistance of environmental and ...
Molecular evidence of hybrid zones of cedrela (Meliaceae) in the yungas of northwestern Argentina
(2016)
In the Yungas of Northwestern Argentina, three endangered species of Cedrela (C. angustifolia, C. saltensis, and C. balansae) follow altitudinal gradients of distribution with contact zones between them. We sampled 210 ...
Molecular characterization of novel Ehrlichia genotypes in Ixodes auritulus from Uruguay
(Elsevier, 2021-04)
Ehrlichia are small intracellular Gram-negative bacteria transmitted by ticks. These microorganisms cause ehrlichiosis, a complex of life-threatening emerging zoonoses and diseases of global veterinary relevance. The aim ...
Mode of Reproduction and Meiotic Chromosome Behavior in Acroceras macrum
(Wiley, 2020-01)
Acroceras macrum Stapf is a high-quality C3 grass species adapted to the subtropics. It is a valuable forage resource in frequently flooded environments. The objectives were to analyze the type of polyploidy, mode of ...
Effect of Vrn-1, Ppd-1 genes and earliness per se on heading time in Argentinean bread wheat cultivars
(2014-03)
Predicting phenology, in particular heading time, is crucial to avoid and/or minimize risk of damage of frost, drought and high temperatures during grain filling. Although some of the major genes controlling development, ...
