Cytological and molecular characterization of three gametoclones of Citrus clementina

2013

Abstract Background Three gametoclonal plants of Citrus clementina Hort. ex Tan., cv. Nules, designated ESP, FRA, and ITA (derived from three labs in Spain, France, and Italy, respectively), were selected for cytological and molecular characterization in order to elucidate genomic rearrangements provoked by haploidization. The study included comparisons of their ploidy, homozygosity, genome integrity, and gene dosage, using chromosome counting, flow cytometry, SSR marker genotyping, and array-Comparative Genomic Hybridization (array-CGH). Results Chromosome counting and flow cytometry revealed that ESP and FRA were haploid, but ITA was tri-haploid. Homozygous patterns, represented by a sing…

Two Remarkably Luminous Galaxy Candidates at z ≈ 10-12 Revealed by JWST

2022

The first few 100 Myr at z > 10 mark the last major uncharted epoch in the history of the universe, where only a single galaxy (GN-z11 at z ≈ 11) is currently spectroscopically confirmed. Here we present a search for luminous z > 10 galaxies with JWST/NIRCam photometry spanning ≈1–5 μm and covering 49 arcmin2 from the public JWST Early Release Science programs (CEERS and GLASS). Our most secure candidates are two MUV ≈ −21 systems: GLASS-z12 and GLASS-z10. These galaxies display abrupt ≳1.8 mag breaks in their spectral energy distributions (SEDs), consistent with complete absorption of flux bluewards of Lyα that is redshifted to =+z12.40.3 0.1and=+z10.40.5 0.4. Lower redshift interlopers su…

Is complying with the recommendations of sodium intake beneficial for health in individuals at high cardiovascular risk? Findings from the PREDIMED s…

2015

Background: Excess sodium intake is associated with high blood pressure, a major risk factor for cardiovascular disease (CVD). It is unknown whether decreasing sodium intake to ,2300 mg/d has an effect on CVD or all-cause mortality. Objective: The objective was to assess whether reductions in sodium intake to ,2300 mg/d were associated with either an increased or a decreased risk of fatal and nonfatal CVD and all-cause mortality. Design: This observational prospective study of the PREvencicon DIeta MEDiterr� (PREDIMED) trial included 3982 participants at high CVD risk. Sodium intake was evaluated with a validated food- frequency questionnaire and categorized as low (,1500 mg/d), in- termedi…

Diversity and Evolution of papillomaviruses

2017

1.1. Introducción Con el fin de averiguar las causas de las devastadoras epidemias de finales del siglo XIX, se llevaron a cabo diferentes estudios que dieron como resultado la identificación de unos nuevos agentes infecciosos, para los que se acuñó el nombre de “virus”. Desde entonces el descubrimiento de nuevos virus ha sido incesante, lo que llevó, en los años 70, a la creación de un organismo encargado de desarrollar, refinar y mantener la clasificación taxonómica de los virus, el Comité Internacional de Taxonomía Viral (ICTV), en el seno de la Unión Internacional de Sociedades Microbiológicas (IUMS). En 2014 este organismo había reconocido 3.186 especies virales pertenecientes a 104 fa…

X-ray spectral and timing characteristics of the stars in the young open cluster IC 2391

2005

We present X-ray spectral and timing analysis of members of the young open cluster IC 2391 observed with the XMM-Newton observatory. We detected 99 X-ray sources by analysing the summed data obtained from MOS1, MOS2 and pn detectors of the EPIC camera; 24 of them are members, or probable members, of the cluster. Stars of all spectral types have been detected, from the early-types to the late-M dwarfs. Despite the capability of the instrument to recognize up to 3 thermal components, the X-ray spectra of the G, K and M members of the cluster are well described with two thermal components (at kT$_1 \sim$ 0.3-0.5 keV and kT$_2 \sim$ 1.0-1.2 keV respectively) while the X-ray spectra of F members…

Pedogenesis and carbon sequestration in transformed agricultural soils of Sicily

2021

The increasing atmospheric CO2 concentration is a consequence of human activities leading to severe environmental deteriorations. Techniques are thus needed to sequester and reduce atmospheric carbon. One of the proposed techniques is the transformation or construction of new soils into which more organic carbon can be sequestered and CO2 be consumed by increased weathering. By using a chronosequence of new and transformed soils on crushed limestone (0–48 years) in a Mediterranean area (Sicily), we tried to quantify the amount of organic carbon that could be additionally sequestered and to derive the corresponding rates. A further aim was to trace chemical weathering and related CO2 consump…

Cropping system dynamics, climate variability, and seed losses among East African smallholder farmers: a retrospective survey.

2014

Abstract Climate variability directly affects traditional low input and rain-fed farming systems, but few studies have paid attention retrospectively to the cropping system’s ability to mitigate climate risk. This study analyzes the impacts of rainfall variability on farmers’ seed variety losses over time, considering changes in smallholder farming systems. The cropping system dynamics, in favoring maize at the expense of sorghum and pearl millet, have induced an increasing risk of seed loss during drought. Combining ecological anthropology and climatology, a retrospective survey asking farmers about the period 1961–2006 was carried out at three altitudinal levels (750, 950, and 1100 m) on …
