Proposal of a Citrus translational genomic approach for early and infield detection of Flavescence dorée in Vitis

Flavescence dore´e (FD) is one of the most widely known grapevine yellows disease and one of the most unabated worldwide in the viticulture sector. In this paper, we outline a strategy for developing an integrated system of technologies to enable rapid, early disease FD detection and diagnosis. We propose the deployment of a newly developed sensor device, the differential mobility spectrometer (DMS), which has shown positive results with a similar vector-borne disease in Citrus. We have previously demonstrated that the gas chromatograph DMS (GC/DMS) can distinguish various citrus diseases, and the system may also allow detection of volatile organic compound (VOC) signals from a tree of othe…

First results on the phenotypic analysis of wild and cultivated species of Pyrus in Sicily

Phenotypic analysis of Pyrus in Sicily using a set of 19 characters on 71 accessions belonging to 7 species is here reported. Results show a high level of morphological variation in this genus. Cluster analysis of the morphological characters allows to identify two groups: the first closely related to wild pears and the latter related to P. communis s. l. and P. sicanorum. It is likely to think that many Ethno-Varieties, usually attributed to P. communis, on the contrary are attributable to wild Sicilian pears and belong to indigenous germplasm.

Evaluation of the DNA barcoding approach to develop a reference data-set for the threatened flora of Sicily

The Mediterranean Basin is one of the most significantly altered World Biodiversity Hotspots with extensive habitat loss and fast genetic population erosion, for which urgent biodiversity reconnaissance and preservation actions are required. In particular, Sicily has about 600 taxa classified as threatened or near-threatened. The correct recognition and identification of such biodiversity is required for supporting further activities. The objective of this work is to assess the ability of the DNA barcoding approach to identify different taxonomic groups from a collection of the most threatened plant taxa, throughout natural Sicilian populations. The evaluation of the DNA barcoding core mark…

Geobotanical approach to detect land-use change of a Mediterranean landscape: a case study in Central-Western Sicily

A landscape is a palimpsest of the interactions between human activities and ecological dynamics. In an interdisciplinary perspective of dialogue between the ‘Two Cultures’ (Natural Sciences and Humanities), a study of a rural area has been carried out through a reading of plant ecosystems as signs of human impact. The purpose of this paper—as part of the project ‘Harvesting Memories’: Ecology and landscape archaeology of Castro/Giardinallo Valley and Mt. Barrau district (Corleone, Palermo, Sicily)—is to analyse the formative-processes of a Sicilian rural landscape and its changes in the last century. A key element in the reconstruction of the formation of the present landscape is the serie…

Sources of geomaterials in the Sicani Mountains during the Early Middle Ages: A case study of Contrada Castro, central western Sicily

From 2017, an unknown rural settlement in Contrada Castro at Corleone (Palermo Province, western Sicily) was investigated as part of the `Harvesting Memories Project¿. The stratigraphic sequence, supported by radiocarbon dating, has demonstrated a reoccupation of a pre-Roman site during the transition between the Byzantine and Islamic periods. In particular, the main occupation occurred in the late 8th¿9th century when pottery kilns and a probable warehouse were constructed. During the 10th¿11th century, a new structure with different orientations replaced the previous buildings that had already collapsed. Specifically focusing on a perspective of the household production and its relationsh…

Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools t…

Land forms, land-use and landscapes in Sicily

Landscape as we perceive it is the product of many different interacting factors: macro- and topoclimate, lithology, geomorphology, land use and human activities. The evaluation of the relative influence of each one of these factors on vegetation pattern and landscape is strongly dependent from the scale of observation. Hierarchical classification (Blasi et al. 2000) makes scale-related use of these factors as diagnostic attributes: macroclimate (over 1:250,000 scale) defines landscape regions, lithology (1:250,000 scale) defines systems and lithomorphology (1:50,000 scale) defines subsystems. At a finer scale (less than 1:10,000), land forms and land-use are the predominant landscape maker…

Influence of Variety and Maturity Stage on Sterolic Composition of Virgin Olive Oil from Central-Western Sicily

Olive oil is one of the most important food products throughout the Mediterranean Basin due to its high nutritional and dietetic value. In recent years, there has been increased interest in the sterols of olive oil for their health benefts and their importance to virgin olive oil quality regulation. The impact of sterols on the human health is proved by several studies, showing that a suffcient quantity of β-sitosterol inhibits the intestinal absorption of LDL-cholesterol. In olive oil the phytosterol concentration ranges from 800 to 2600 mg kg-1. Sterol esters evaluation has been proposed as useful parameter in studies related to varietal and geographical discrimination. Cultivar and matur…

PAESAGGIO VEGETALE, NATURALITÀ E RETE ECOLOGICA DEL COMPRENSORIO DEL PARCO DEI MONTI SICANI (SICILIA)

I Monti Sicani costituiscono un comprensorio montuoso-collinare, a prevalente ossatura carbonatica di era mesozoica, localizzato tra le province di Palermo e Agrigento (Sicilia centro-occidentale). Esteso circa 2.800 km2 si spinge a settentrione fino a Rocca Busambra mentre a meridione fino al complesso di Rocca Ficuzza-Monte Telegrafo; ad occidente i confini sono segnati dalle colline trapanesi di Salaparuta mentre ad oriente dall’Alta Valle del Platani. In tale contesto s’inserisce il Parco dei Monti Sicani istituito con L.R. n. 6 del 14 maggio 2009 e che, in base alle determinazioni dell’ARTA, interesserebbe il territorio di 12 Comuni (Bivona, Burgio, Cammarata, Castronovo di Sicilia, Ch…

Studio botanico finalizzato al recupero del paesaggio vegetale dell’Area archeologica di Lilibeo presso Marsala (Sicilia occidentale)

Viene presentato uno studio botanico volto al recupero del paesaggio vegetale dell’Area Archeologica di Capo Lilibeo (Marsala). Il progetto prevede l’eradicazione delle specie esotiche ad alto grado di invasività quali Ailanthus altissima e Vachellia karroo, il risanamento fitosanitario dei viali di Palme delle Canarie e la sostituzione degli individui malformati con specie ornamentali altamente decorative e a basso grado di invasività. E’ previsto l’impiego di specie afferenti agli stadi più evoluti dei sigmataxa Chamaeropo humilis- Querceto calliprini sigmetum ed al Pistacio lentisci- Chamaeropo humilis sigmetum al fine di assicurare i migliori risultati contro l’espansione della componen…

La sindrome delle aree protette

Al di là di inevitabili specificità legate a singoli contesti, i parchi naturali europei presentano un quadro sintomatico comune, riconducibile all'interazione di tre principali eziologie. Un primo problema è quello della notevole "parcellizzazione", amministrativa e gestionale, di aree sottoposte a vincoli di tutela non sempre omogenei e spesso affidate ad istituti diversi. Un secondo agente eziologico è quello dei "processi in atto", quale conseguenza dei rapidi cambiamenti socio-economici della nostra società. Come spesso accade, quando si devono compiere scelte gestionali, occorre stabilire delle priorità. Il terzo agente eziologico è legato proprio alla disparità di vedute tra chi prop…

Compositions and Sensory Characterization of Olive Oils from CentralWestern Sicily

In Sicily, olive has been cultivated since ancient times and its germplasm is characterized by a wide genetic diversity that could be related to its domestication and spread in ancient times, and to some reproductive biological peculiarities as self-incompatibility. In this research, EVOO of Sicilian heritage such as Nocellara del Belice, Biancolilla, Biancolilla centinara and Passulunara, was been investigated. The assessment regards main chemical-physical parameters and sensory profles, based on the olfactory and gustatory characteristics. Samples were obtained from Bona Furtuna farm (Corleone, C-W Sicily), equipped with a continuous two and half phases cold extraction system. Results sho…

Fatty acid composition of the seed lipids ofChamaerops humilisL. natural populations and its relation with the environment

Seed lipids composition is a tool to discriminate among plant taxa and is related to phylogeny and biogeographic distribution. Aim of the present study was to evaluate the fatty acid (FA) composition of the seed lipids from nine natural Chamaerops humilis L. population and its relation with the climatic traits of the collection sites. The average seed lipids content was 54.8 g kg21 and the most represented FAs were oleic (478 g kg21 oil) and linoleic (230 g kg21 oil), with significant differences among the accessions. Most of the lipid traits significantly correlated with climatic traits. In particular, oleic acid negatively correlated with year potential evapotranspiration. These relations…

Tertiary relict laurophyll vegetation in the Madonie mountains (Sicily)

:Laurel woodlands in the Madonie mountains (Sicily) are characterized by the presence of Laurus nobilis, Rhamnus lojaconoi and Vitis vinifera subsp. sylvestris. The results of a phytosociological study are presented, and a new endemic association, Rhamno lojaconoi–Lauretum nobilis, is described. Present Mediterranean laurel communities are the result of an adaptive response by Tertiary laurel forest to the peculiar microclimatic conditions that characterize the refugia where they persist. These refugia have been recently considered as a priority habitat under the Directive 92/43/EEC, and their plant communities are very vulnerable. Protection measures of the studied laurel populations are n…
