Introduction bottleneck and the contribute of Mesoamerican and Andean gene pools to common bean (Phaseolus vulgaris L.) diversity in Europe.
Common bean (Phaseolus vulgaris L., 2n = 2x = 22) is the most important edible food legume for direct human consumption in Europe and in the world as it represents a valuable source of proteins, vitamins, fibres, and minerals. Genetic and archaeological studies have shown that domestication of P. vulgaris was originated and domesticated in the New World and has two major gene pools, the Andean and the Mesoamerican, based on their centers of origin in South and Central America, respectively. After the first voyages of Columbus (1492) common bean was brought to Europe but historical and linguistic sources provide little evidence of the introduction and expansion of common bean in Europe. In common bean a large number of nuclear microsatellite markers (nuSSRs) have been already developed and mapped that show relatively high levels of polymorphism, thus providing an attractive choice for describing population structure. However, to the best of our knowledge, population studies of the European common bean, using nuSSRs, so far have been performed with only a small number of landraces or a small number of samples from a few geographic regions. In the present study, we used thirteen highly polymorphic nuSSRs to assess
the genetic structure and level of diversity of a large collection of European landraces (256
individuals), in comparison with a representative American sample (89 individuals). Moreover, to
obtain a detailed picture and to elucidate the effects of bottleneck of introduction and selection for
adaptation during the expansion of common bean over the whole Europe, we also complemented
the nuSSRs analysis by information provided by a Bayesian analysis implemented in
STRUCTURE. Here, we present and discuss the role that inter-gene pool hybridization have had in
shaping the genetic structure of the European bean landraces. The implication for evolution and the
advantages for common bean breeding are also discussed
Agronomic, nutritional and nutraceutical aspects of durum wheat (Triticum durum Desf.) cultivars under low input agricultural management
Among cereals, durum wheat has a central role in the Italian diet and economy, where there is a historical tradition of pasta making. In the present study, we evaluated the nutrient and nutraceutical properties of 2 old and 6 modern durum wheat varieties grown under low input agricultural management. Considering the lack of available data on the adaptability of existing durum wheat varieties to the low input and organic sectors, the research aimed at providing a complete description of the investigated genotypes, considering the agronomic performance as well as the nutrient and phytochemical composition. The experimental trials were carried out at the same location (Bologna, Northern Italy) for two consecutive growing seasons (2006/2007, 2007/2008). No clear distinction between old and modern varieties was observed in terms of grain yield (mean values ranging from 2.5 to 4.0 t/ha), highlighting that the divergence in productivity, normally found between dwarf and non-dwarf genotypes, is strongly reduced when they are cropped under low input management. All durum wheat varieties presented high protein levels and, in addition, provided remarkable amounts of phytochemicals such as dietary fibre, polyphenols, flavonoids and carotenoids. Some of the investigated genotypes, such as Senatore Cappelli, Solex, Svevo and Orobel, emerged with intriguing nutritional and phytochemical profiles, with the highest levels of dietary fibre and antioxidant compounds. The study provided the basis for further investigations into the adaptability of the durum wheat genotypes to low input management, for the selection of genotypes characterised by higher yield and valuable nutrient and nutraceutical quality
Company ‘Emigration’ and EC Freedom of Establishment: Daily Mail Revisited
Following the ECJ’s recent case law on EC freedom of establishment (the Centros, Überseering and Inspire Art cases), regulatory competition for corporate law within the European Union takes place at an early stage of the incorporation of new companies. In contrast, as regards the ‘moving out’ of companies from the country of incorporation, the ECJ once considered a tax law restriction against the transfer abroad of a company’s administrative seat as compatible with EC freedom of establishment (the Daily Mail case). For years, this decision has been regarded as applicable to all restrictions imposed by countries of incorporation, even the forced liquidation of the ‘emigrating’ company. This paper addresses the question whether EC freedom of establishment really allows Member States to place any limit on the ‘emigration’ of nationally registered companies. It argues that EC freedom of establishment covers the transfer of the administrative seat as well as the transfer of the registered office and, therefore, that the country of incorporation cannot liquidate ‘emigrating’ companies. In addition, it addresses the question whether a new Directive is needed to allow the transfer of a com- pany’s registered office and the identity-preserving company law changes. It argues that such a Directive is necessary to avoid legal uncertainty and to protect the interests of employees, creditors and minority shareholders, among others, who could be detrimentally affected by the ‘emigration’ of national companies
Miglioramento degli standard qualitativi delle produzioni dei seminativi
Nell'ambito delle produzioni agricole possono essere considerati diversi aspetti per definire il concetto di qualit\ue0, che pu\uf2 comprendere aspetti tecnologici, sanitari e funzionali. La complessit\ue0 nel definire la qualit\ue0 e gli aspetti da considerare per ottenere una valutazione globale dell'alimento, rendono la valutazione molto complicata. Per anni il miglioramento genetico, e le tecniche agronomiche, sono stati orientati nel definire parametri legati alle caratteristiche produttive e tecnologiche, ignorando quasi del tutto gli aspetti legati alla nutrizione. Oggi con le nuove tecnologie di analisi \ue8 possibile valutare molto pi\uf9 integralmente un prodotto ottenuto dall'attivit\ue0 agricola, considerando tutti quei metaboliti secondari che sono spesso responsabili del sapore, dell'odore e delle qualit\ue0 funzionali di un alimento. Quindi \ue8 possibile orientare il miglioramento genetico e le tecniche agronomiche, per ottenere il giusto compromesso tra gli aspetti produttivi, tecnologici, sanitari e di qualit\ue0 alimentare e funzionale, per ottenere prodotti nel rispetto dell'ambiente e dell'organismo che se ne nutre
