Identification and characterization of durum wheat microRNAs in leaf and root tissues.
2017
MicroRNAs are a class of post-transcriptional regulators of plant developmental and physiological processes and responses to environmental stresses. Here, we present the study regarding the annotation and characterization of MIR genes conducted in durum wheat. We characterized the miRNAome of leaf and root tissues at tillering stage under two environmental conditions: irrigated with 100% (control) and 55% of evapotranspiration (early water stress). In total, 90 microRNAs were identified, of which 32 were classified as putative novel and species-specific miRNAs. In addition, seven microRNA homeologous groups were identified in each of the two genomes of the tetraploid durum wheat. Differenti…

Power monitoring in dielectric-loaded surface plasmon-polariton waveguides
2011
We report on propagating mode power monitoring in dielectric-loaded surface plasmon-polariton waveguides (DLSPPWs) by measuring the resistance of gold stripes supporting the DLSPPW mode propagation. Inevitable absorption of the DLSPPW mode in metal causes an increase in the stripe temperature and, thereby, in its resistance whose variations are monitored with an external Wheatstone bridge being accurately balanced in the absence of radiation in a waveguide. The investigated waveguide configuration consists of a 1-µm-thick and 10-µm-wide polymer ridges tapered laterally to a 1-µm-wide ridge placed on a 50-nm-thin and 4-µm-wide gold stripe, all supported by a magnesium fluoride substrate. Usi…
The sensitivity of buckwheat plants to pathogens under conditions of mixed viral and mycoplasmal infection
2016
It was investigated, that mixed infection of buckwheat distributed in various ecological regions of Ukraine, the pathogens that belong to different taxonomic groups have different and peculiar morphological and structural properties. First was shown that buckwheat is affected by buckwheat burn virus (BBV) together with Mycoplasma. Mixed infection leads to proliferation of sepals, clarification of the flowers petals, reduction and greening of petals, hypoplasia or hypodevelopment of stamens and pistils: all of this can lead to partial or complete sterility.
Basic Physical-Chemical and Sensorial Evaluation of Some Fermented Mashes Produced from Wheat, Husked Millet, Barley Malt and Oat
2012
Abstract Fermented mashes based on different cereal grist are a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. These mashes are a thick consistency and sour-sweet taste, different colors depending on the ingredients and method of preparation. In this study were determined the main physical and chemical characteristics (pH, volatile and total acidity, total and soluble dry substances, alcohol concentration, dynamic viscosity) and was made sensorial analysis of some boiled aqueous mashes obtained from wheat, husked millet, barley malt and oat. Mashes were fermented at 30 °C with a mixed culture of mesophilic cheese lactic acid ba…
A Non-Invasive Thermal Drift Compensation Technique Applied to a Spin-Valve Magnetoresistive Current Sensor
2011
A compensation method for the sensitivity drift of a magnetoresistive (MR) Wheatstone bridge current sensor is proposed. The technique was carried out by placing a ruthenium temperature sensor and the MR sensor to be compensated inside a generalized impedance converter circuit (GIC). No internal modification of the sensor bridge arms is required so that the circuit is capable of compensating practical industrial sensors. The method is based on the temperature modulation of the current supplied to the bridge, which improves previous solutions based on constant current compensation. Experimental results are shown using a microfabricated spin-valve MR current sensor. The temperature compensati…
Grano duro 2019: Italia divisa in due per rese e qualità. Dettaglio regionale dei risultati 2019: Sicilia.
2019
Nell’annata agraria 2018-2019 la Rete nazionale di valutazione delle varietà di frumento duro, coordinata dal CREA, ha previsto l’allestimento in Sicilia di quattro campi sperimentali, realizzati nei seguenti ambienti: Libertinia (Catania), Catania, S. Stefano Quisquina (Agrigento) e Caltagirone (Catania). Irisultati di quest’annata agraria hanno mostrato risposte produttive interessanti di diverse nuove varietà che, al primo anno di valutazione nella Rete nazionale, si affacciano sul mercato sementiero del frumento duro. Tali risultati andranno verificati nelle successive stagioni colturali.
Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces
2021
Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…

Study of surface carbohydrates on isolated Golgi subfractions by fluorescent-lectin binding and flow cytometry
1995
The Golgi complex is a functionally heterogeneous subcellular structure that plays a key role in the synthesis, maturation, and sorting of newly synthesized glycoproteins. Fluorescent lectins have been used extensively to analyze surface glycoproteins by flow cytometry in whole cells and more recently in isolated subcellular organelles, such as mitochondria and chloroplasts. We report here the use of several fluorescein-isothiocyanate-conjugated lectins to detect and quantify specific surface sugars by flow cytometry on isolated elements from purified cis and trans-Golgi fractions from rat liver. Our results show that this approach may be useful to study Golgi composition and function, sinc…
