Use of nodulation pattern, stress tolerance, nodC gene amplification, RAPD-PCR and RFLP-16S rDNA analysis to discriminate genotypes of Rhizobium legu…
2005
Twenty-seven new Rhizobium isolates were obtained from root nodules of wild and crop legumes belonging to the genera Vicia, Lathyrus and Pisum from different agroecological areas in central and southern Italy. A polyphasic approach including phenotypic and genotypic techniques was used to study their diversity and their relationships with other biovars and species of rhizobia. Analysis of symbiotic properties and stress tolerance tests revealed that wild isolates, showed a wide spectrum of nodulation and a marked variation in stress tolerance compared with reference strains tested in this study. All rhizobial isolates (except for the isolate CG4 from Galega officinalis) were presumptively i…
Identification of Leguminosae gums and evaluation of carob-guar mixtures by capillary zone electrophoresis of protein extracts.
2002
A procedure for the extraction and capillary zone electrophoresis (CZE) separation of proteins from carob, guar and tara gums in a background electrolyte (BGE) of pH 9 containing 0.1% polyvinyl alcohol is described. The CZE protein profiles exhibit characteristic peaks for each one of the Leguminosae gums, which can be used to construct models capable of identifying samples of carob, guar and tara gums, and predicting the guar content in binary carob-guar mixtures of different geographical origin and harvested in different years. The classification and prediction models are constructed by using linear discriminant analysis (LDA) and multiple linear regression (MLR), respectively. An excelle…
Crystallization of Light-Harvesting Complex II From Vicia Faba (Fabaceae)
1998
The most abundant chlorophyll binding complex in plants is the intrinsic light-harvesting complex II (LHC II), comprising about half of the total chlorophyll in thylakoid membranes. The structure of LHC II has been determined by electron crystallography, providing a three-dimensional map at 3.4 A (1). Nevertheless, high-resolution structure based on x-ray crystallography is still missing because of the lack of highly ordered 3-D crystals. While delipidation of membrane proteins suitable for high-quality 3-D crystals seems to be a prerequisite, in case of LHC H delipidation leads to a loss of the ability to crystallize. So far, standard purification methods like chromatography have been proo…
Le specie ornamentali della famiglia delle Fabaceae coltivate nella Sicilia Occidentale con chiave di identificazione
2004
ABSTRACT- The family Fabaceae: the ornamental species cultivated in a Mediterranean area (W Sicily, Italy) and an identification key for - A study undertaken between 1997 and 2000 in a Mediterranean area, W Sicily (Italy), has shown that the ornamental flora of is formed by 633 species, of which 38 appertain to 21 genera. Indications of this family, genus and species are given with an identification key. Trees, shrubs, herbaceous and climbing species belonging to Fabaceae and cultivated in Western Sicily gardens are listed.
Late Quaternary distributional stasis in the submediterranean mountain plant Anthyllis montana L. (Fabaceae) inferred from ITS sequences and amplifie…
2002
Anthyllis montana is a submediterranean, herbaceous plant of the southern and central European mountains. The internal transcribed spacer (ITS) regions of nuclear ribosomal DNA were sequenced from multiple accessions of the species and several closely related taxa. In addition, amplified fragment length polymorphism (AFLP) was analysed from 71 individuals of A. montana collected in 20 localities, mainly in the Pyrenees, Alps, Italian Peninsula and Balkans. Our ITS phylogeny showed a sequential branching pattern in A. montana, implying a western Mediterranean origin followed by an eastward migration. ITS clock calibrations suggest that speciation of A. montana took place at the Pliocene-Plei…
Phylogenetics of Anthyllis (Leguminosae: Papilionoideae: Loteae): Partial incongruence between nuclear and plastid markers, a long branch problem and…
2010
Abstract Phylogenetic relationships in the genus Anthyllis (Leguminosae: Papilionoideae: Loteae) were investigated using data from the nuclear ribosomal internal transcribed spacer regions (ITS) and three plastid regions (psbA–trnH intergenic spacer, petB–petD region and rps16 intron). Bayesian and maximum parsimony (MP) analysis of a concatenated plastid dataset recovered well-resolved trees that are topologically similar, with many clades supported by unique indels. MP and Bayesian analyses of the ITS sequence data recovered trees that have several well-supported topological differences, both among analyses, and to trees inferred from the plastid data. The most substantial of these concer…
Effect of cooking and legume species upon calcium, iron and zinc uptake by Caco-2 cells
2006
Abstract An in vitro system, consisting of simulated gastrointestinal digestion and Caco-2 cell culture, was used to estimate the uptake of calcium, iron and zinc from white beans, chickpeas and lentils, and the effect of cooking upon uptake, with the ultimate aim of evaluating legumes as a dietary source of the aforementioned minerals. In raw products, differences were observed in the uptake percentages by Caco-2 cells of a same mineral from different legumes, although these were not related to the total mineral content. In the three elements studied, the highest uptake values corresponded to chickpeas. Traditional cooking significantly ( p 0.05 ) increased the uptake (%) of calcium, iron …

Chemical composition of the essential oil from the aerial parts of Ononis reclinata L. (Fabaceae) grown wild in Sicily
2016
In the present study, the chemical composition of the essential oil from aerial parts of Ononis reclinata L., a species not previously investigated, collected in Sicily was evaluated by GC and Gas chromatography-Mass spectrometry. The main components of O. reclinata were menthone (43.6%), isopimpinellin (38.4%) and pulegone (11.2%). The comparison with other studied oils of genus Ononis showed a peculiar and characteristic profile.
A chemometric approach to evaluate the impact of pulses, Chlorella and Spirulina on proximate composition, amino acid, and physicochemical properties…
2019
Changes in physicochemical parameters, proximate composition, amino acid and taste profiles of turkey burgers enriched at 1% with soy (control), pulses, Chlorella and Spirulina proteins were studied. Results: Color parameters, pH, ash content, total, essential and non-essential amino acids were significantly different among the different type of turkey burgers prepared. In this regard, turkey burgers made with pea protein presented the highest values for pH and lightness, whereas the samples prepared with broad bean showed the highest redness. The inclusion of bean and seaweed produced a marked increase of glutamic acid, lysine and aspartic acid. However, the taste profile was similar in th…
