Improving cereal grain carbohydrates for diet and health
No full textAbstractStarch and cell wall polysaccharides (dietary fibre) of cereal grains contribute to the health benefits associated with the consumption of whole grain cereal products, including reduced risk of obesity, type 2 diabetes, cardiovascular disease and colorectal cancer. The physiological bases for these effects are reviewed in relation to the structures and physical properties of the polysaccharides and their behaviour (including digestion and fermentation) in the gastro-intestinal tract. Strategies for modifying the content and composition of grain polysaccharides to increase their health benefits are discussed, including exploiting natural variation and using mutagenesis and transgenesis to generate further variation. These studies will facilitate the development of new types of cereals and cereal products to face the major health challenges of the 21st century
The pictorial wit of Domenico Tiepolo
No full textThis thesis takes a new approach to Domenico Tiepolo’s (1727-1804), Divertimento Per li Regazzi (c.1795-1804), it is arguably the artists most enigmatic graphic work, which features the commedia dell’arte character Pulcinella. The drawings have hitherto been subject to rigorous connoisseurial analysis. Indeed, in his introduction to ten of the drawings in a catalogue of Italian Eighteenth-Century Drawings in The Robert Lehman Collection at the Metropolitan Museum of Art, New York, James Byam Shaw states that this particular series of drawings has now become so famous ‘that it is hardly necessary to add to the literature of the series.’1 In my opinion it would be a great pity if future generations of scholars were discouraged by this remark, for I believe the drawings still have much to ‘tell’ the contemporary art historian and would further benefit from increasingly interpretative readings. Previously, scholars have regarded Domenico Tiepolo as an imitator of his father, Giambattista Tiepolo (1696-1770), and interpreted the re-appropriation of motifs in the Divertimento as signs of old age and fatigue. I suggest, on the contrary, that in this series of drawings in particular, Domenico was an innovator.
This project carves out new territories within the study of the series in that it focuses on the playful nature of the drawings, and how the suite can be understood in relation to contemporary theory concerning games and play, and ludic musical/improvisatory forms. Additionally, the drawings are discussed as a case history in a now popular emerging dialectic on the late works of aged artists: here I consider how these drawings, often funny, poignant, sensitive and delicate reveal how the elderly painter reconciles himself not only to the passing of his own life and the extinction of his family line but to an entire political, cultural and visual tradition

Domenico Venier's Poetics and Petrarchism in Sixteenth-Century Veneto
No full textreservedIl presente elaborato si propone di indagare il fenomeno del petrarchismo cinquecentesco in area veneta, concentrandosi in particolare sulla figura di Domenico Venier, tra i più rappresentativi interpreti della lirica petrarchesca nel contesto veneziano del XVI secolo. Attraverso un’analisi delle principali istanze tematiche e stilistiche rintracciabili nella sua produzione poetica, la tesi intende delineare un profilo letterario dell’autore che tenga conto non solo della tradizione petrarchesca, ma anche delle caratteristiche culturali e sociali del contesto lagunare. Particolare attenzione è riservata al cenacolo venieriano, luogo privilegiato di scambio intellettuale e di sperimentazione poetica, che svolse un ruolo significativo nella diffusione e nella rielaborazione del canone lirico stabilito da Pietro Bembo nella prima metà del Cinquecento. La tesi prende inoltre in esame la ricezione critica della poesia di Venier, con l’obiettivo di ricostruire le diverse prospettive interpretative che hanno contribuito a delineare l’immagine letteraria del poeta nel corso dei secoli.This thesis aims to investigate the phenomenon of sixteenth-century Petrarchism in the Veneto region of Northern Italy, with a particular focus on the figure of Domenico Venier, one of the most prominent exponents of Petrarchan lyric poetry of the time. Through an analysis of the main thematic and stylistic features that characterize his poetic production, the study seeks to outline a literary profile of the author, considering not only the Petrarchan tradition but also the cultural and social characteristics of the Venetian context. Special attention is given to Venier’s social circle, a privileged space for intellectual exchange and poetic experimentation, which played a significant role in the dissemination and reworking of the lyric canon established by Pietro Bembo in the first half of the sixteenth century. The thesis also examines the critical reception of Venier’s poetry, aiming to reconstruct the various interpretative perspectives that have contributed to shaping the poet’s literary image throughout the centuries

Abstract
Key message Knocking down GW2 enhances grain size by regulating genes encoding the synthesis of cytokinin,
gibberellin, starch and cell wall.
Abstract Raising crop yield is a priority task in the light of the continuing growth of the world’s population and the inexorable
loss of arable land to urbanization. Here, the RNAi approach was taken to reduce the abundance of Grain Weight 2
(GW2) transcript in the durum wheat cultivar Svevo. The effect of the knockdown was to increase the grains’ starch content
by 10–40%, their width by 4–13% and their surface area by 3–5%. Transcriptomic profiling, based on a quantitative
real-time PCR platform, revealed that the transcript abundance of genes encoding both cytokinin dehydrogenase 1 and the
large subunit of ADP-glucose pyrophosphorylase was markedly increased in the transgenic lines, whereas that of the genes
encoding cytokinin dehydrogenase 2 and gibberellin 3-oxidase was reduced. A proteomic analysis of the non-storage fraction
extracted from mature grains detected that eleven proteins were differentially represented in the transgenic compared
to wild-type grain: some of these were involved, or at least potentially involved, in cell wall development, suggesting a role
of GW2 in the regulation of cell division in the wheat grain
Domenico Gerosolimitano a Venezia
No full textIn this article, the author provides the Hebrew name of Domenico Gerosolimitano, a famous ecclesiastical censor of Hebrew books who lived in Italy from the end of the sixteenth through the second decade of the seventeenth centuries. Based on the discovery of his baptismal act, recorded in Venice, Domenico Gerosolimitano's Hebrew name was Rabbi Samuel Vivas, of Jerusalem. The aforementioned act determines the exact date of his conversion to Catholicism, as 6 August, 1593. The author presents new information concerning Domenico´s life in Venice as well as his activities as censor of Hebrew books.El artículo se ocupa de la identificación hebrea de Domenico Gerosolimitano, célebre censor de libros hebreos que trabajó en Italia entre fines del siglo XVI y los primeros veinte años del XVII. Gracias a haber descubierto en Venecia el acta de bautismo, el autor ha logrado identificar a Domenico Gerosolimitano con el rabino Samuel Vivas de Jerusalén y precisar la fecha exacta de su conversión al catolicismo (6 de agosto de 1593). El estudio arroja además nueva luz sobre la estancia en Venecia de Domenico y sobre sus inicios como censor de libros hebreos
Table1_Whole-exome sequencing of selected bread wheat recombinant inbred lines as a useful resource for allele mining and bulked segregant analysis.DOCX
No full textAlthough wheat (Triticum aestivum L.) is the main staple crop in the world and a major source of carbohydrates and proteins, functional genomics and allele mining are still big challenges. Given the advances in next-generation sequencing (NGS) technologies, the identification of causal variants associated with a target phenotype has become feasible. For these reasons, here, by combining sequence capture and target-enrichment methods with high-throughput NGS re-sequencing, we were able to scan at exome-wide level 46 randomly selected bread wheat individuals from a recombinant inbred line population and to identify and classify a large number of single nucleotide polymorphisms (SNPs). For technical validation of results, eight randomly selected SNPs were converted into Kompetitive Allele-Specific PCR (KASP) markers. This resource was established as an accessible and reusable molecular toolkit for allele data mining. The dataset we are making available could be exploited for novel studies on bread wheat genetics and as a foundation for starting breeding programs aimed at improving different key agronomic traits.</p
Does Fe accumulation in durum wheat seeds benefit from improved whole-plant sulfur nutrition?
No full textSulphur (S) and iron (Fe) are an essential macro- and micronutrients for plant growth and development. A balanced supply of S and Fe for plants is of major importance since it has been demonstrated that plant capability to take up and accumulate Fe is strongly dependent on S availability in the growth medium and vice versa. In fact, that Fe deficiency adaptation requires the adjustment of S uptake and assimilation rate. Furthermore, it has been demonstrated that providing S above adequate concentrations may result in the improvement of Fe use efficiency in wheat plants and this S nutritional effect seems to be especially advantageous for plants grown under severe Fe limitation.
Aim of this study was to evaluate whether and to what extent the changes in S nutrition affect Fe accumulation into grains and whether grain Fe concentrations are significantly correlated with the concentration of Fe in the vegetative tissue.
This approach might represent an important tool to realize the improvement of the nutritional value of food crops by increasing Fe content (agronomic biofortification) through soil and crop management strategies which allow to may prevent Fe deficiency in crops without additional input of Fe fertilizers.
Durum wheat plants were grown on sand/perlite mixture with sufficient (1.2 mM) and high (2.5 mM) S supplies and with 10 or 80 M Fe-EDTA during the life cycle.
In particular, we will discuss the effect of S supply on plant growth parameters (fresh and dry weight and chlorophyll content) and on total S accumulation rate at both leaf and seed level. In addition, the relative changes of the leaf and seed ionome induced by different nutritional conditions were evaluated by using inductively coupled plasma-optical emission spectroscopy (ICP-OES). Finally, whole seeds and seed sections were subjected toinvestigated with micro-focused X-ray fluorescence (XRF) imaging to clarify the elemental distribution maps.of several elements, including S and Fe. Significant differences in the concentration and distribution of a number of elements could be observed according to the different treatments
