“…In addition, analyses of the clones derived from restriction assays in C. pubescens suggested that the differential functional status of 18S-25S rDNA loci (nucleolar organizer regions -NORs- or cHet) in this species is related to a divergence in a short sequence upstream the regulatory transcription initiation site (TIS) of the intergenic spacer (IGS). …”

Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term por Iturri, Laura Antonela, Buschiazzo, Daniel Eduardo

“…We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired soils, developed on similar parent materials, within a climatic sequence (ustic to udic water regimes), and measured: 1) the extent of pH changes, 2) how these changes affected chemical and mineralogical soil properties and 3) how the soils, according to their H+ buffering substances, can react in the future if N-fertilization and acidification continue. …”

Genetic variation for tolerance to high temperatures in a population of Drosophila melanogaster por Rolandi, Carmen, Lighton, John R.B., De La Vega, Gerardo, Schilman, Pablo Ernesto, Mensch, Julián

“…To do so, we used adult flies derived from a natural population belonging to the Drosophila Genetic Reference Panel, for which genomic sequencing data are available. We characterized the phenotypic variation of the upper thermal limit in 34 lines by measuring knockdown temperature (i.e., critical thermal maximum [CTmax]) by exposing flies to a ramp of increasing temperature (0.25°C/min). …”

Max, Lambrides, Christopher J., Dalzell, Scott A., Macfarlane, David C., Murtagh, G. John

“…Further studies are needed, including: (a) physical sampling to determine the depth of active roots; (b) how defoliation affects rooting behaviours and water use of leucaena; and (c) modelling of the water and salt balances of leucaena and grass inter-row systems using data from this study, with various levels of irrigation, to investigate the risks of deep drainage over an extended climate sequence.…”

Evidence of a fixed internal gene constellation in influenza A viruses isolated from wild birds in Argentina (2006–2016) por Rimondi, Agustina, Gonzalez Reiche, Ana Silvia, Olivera, Valeria Soledad, Decarre, Julieta, Castresana, Gabriel Julián, Romano, Marcelo, Nelson, Martha I., van Bakel, Harm, Pereda, Ariel Julian, Ferreri, Lucas, Geiger, Ginger, Perez, Daniel Roberto

“…Cloacal swabs and feces samples (n = 6595) were collected from 62 bird species in Argentina from 2006 to 2016 and screened for influenza A virus. Full genome sequencing of 15 influenza isolates from 6 waterfowl species revealed subtypes combinations that were previously described in South America (H1N1, H4N2, H4N6 (n = 3), H5N3, H6N2 (n = 4), and H10N7 (n = 2)), and new ones not previously identified in the region (H4N8, H7N7 and H7N9). …”

Capacity of two Staphylococcus aureus strains with different adaptation genotypes to persist and induce damage in bovine mammary epithelial cells and to activate macrophages por Sacco, Sofía Clara, Velázquez, Natalia S., Renna, María Sol, Beccaria, Camila, Baravalle, Celina, Pereyra, Elizabet Amanda Lorena, Monecke, Stefan, Calvinho, Luis Fernando, Dallard, Bibiana Elisabet

“…Two isolates (designated 806 and 5011) from bovine intramammary infection (IMI) harboring genes involved in adherence and biofilm production, belonging to different capsular polysaccharide (CP) type, accessory gene regulator (agr) group, pulsotype (PT) and sequence type/clonal complex (ST/CC). Strains 806 and 5011 were associated with low (nonpersistent-NP) and high (persistent-P) adaptation to the MG, respectively. …”

Glyphosate Biodegradation Potential in Soil Based on Glycine Oxidase Gene (thiO) from Bradyrhizobium por Hernandez Guijarro, Keren, De Geronimo, Eduardo, Erijman, Leonardo

“…A quantitative PCR assay was designed to target a specific region of the glycine oxidase gene (thiO), involved in the oxidation of glyphosate to AMPA, from known sequences of Bradyrhizobium species. The abundance of the thiO gene was determined in response to herbicide application in soils with different GP exposure history both under field and microcosm conditions. …”

Inheritance pattern of tetraploids pummelo, mandarin, and their interspecific hybrid sour orange is highly influenced by their phylogenomic structure por Aleza, Pablo, Garavello, Miguel, Rouiss, Houssem, Benedict, Ana Cristina, García-Lor, Andrés, Hernández, María, Navarro, Luis, Ollitrault, Patrick

“…In this work, we have analyzed the inheritance pattern of three tetraploid genotypes: ‘Chandler’ pummelo (Citrus maxima) and ‘Cleopatra’ mandarin (Citrus reticulata), which represent two clear examples of autotetraploid plants constituted by the genome of a single species, and the ‘Sevillano’ sour orange, which is an allotetraploid interspecific hybrid between C. maxima and C. reticulata. Polymorphic simple sequence repeat (SSR) and single-nucleotide polymorphism (SNP) markers were used to estimate parental heterozygosity restitution, and allele frequencies for centromeric loci were used to calculate the preferential pairing rate related to the proportion of disomic and tetrasomic segregation. …”
