A new species of Brassica sect. Brassica (Brassicaceae) from Sicily
2013
Among the suffruticose cabbages of Brassica sect. Brassica, a new species from Sicily, named B. raimondoi, is described and illustrated. It is a chasmophyte restricted to some steep limestone cliffs near Taormina (NE Sicily) and is morphologically related to B. incana, with which it shares densely hairy, broad, amplexicaul leaves and winged petioles, but differs principally in its white corolla, larger floral pieces, more developed stigmatic papillae, shorter siliquae with keeled valves and a smaller, seedless beak, smaller seeds differing in testa microsculpture. A key for the identification of the currently known Sicilian taxa of the section is provided.
Agronomic performance and energetic potential of two Brassica oilseed species in Sicily, Italy
2018
Industrial crops for energy purposes are object of increasing interest worldwide and play an important role as a source of renewable energy. The aims of this study were to evaluate: i) the agronomic performance of Brassica napus L. var. oleifera D.C. and Brassica carinata A. Braun in a semi-arid environment; ii) to evaluate the economic viability of a pilot combined heat and power (CHP) plant operating on pure vegetable oil (PVO). The research was carried out in Sicily (Italy). The main biometric and yield parameters of the two species were determined. Chemical-physical characterizations were carried out on PVO for each species using specific protocols. The cogeneration of renewable energy …
Bio-Agronomic Evaluation of Brassica Carina A. Braun in a Semi-Arid Area of Sicily
2011
The need to reduce fossil fuel consumption for environmental and economic reasons is placing the farming sector in a whole new light with a new set of tasks to face. Concerns arising from climate change and decisions resulting from the Kyòto Protocol have helped reinforce the idea that multifunctional farms can make a real contribution to achieving the targets set for 2012. As a producer of dedicated energy crops – crops used to supply biomass for energy – the farm becomes a supplier of raw materials for fuel production or of energy directly. For economic, social and environmental reasons, agro-energy may be the way forward to encourage multi-functionalism in farming and, therefore, increas…
Anti-Inflammatory Potential of Brassicaceae-Derived Phytochemicals: In Vitro and In Vivo Evidence for a Putative Role in the Prevention and Treatment…
2022
AbstractAbstract Inflammatory bowel disease (IBD) is a group of intestinal disorders, of unknown etiology, characterized by chronic inflammation within the gut. They are gradually becoming critical because of the increasing incidence worldwide and improved diagnosis. Due to the important side effects observed during conventional therapy, natural bioactive components are now under intense investigation for the prevention and treatment of chronic illnesses. The Brassicaceae family comprises vegetables widely consumed all over the world. In recent decades, a growing body of literature has reported that extracts from the Brassicaceae family and their purified constituents have anti-inflammatory…
Tocopherol, fatty acid and phytosterol content in seeds of nine wild taxa of Sicilian Brassica (Cruciferae)
2010
The purpose of this study was to determine tocopherol (Toc), fatty acid and phytosterol content in dry seeds of nine wild taxa of Sicilian Brassica sect. Brassica. Analyses were performed by gas chromatography (GC)-mass spectroscopy (MS). The biochemical analysis of dry seeds showed that in the nine taxa examined, α - and γ -Toc were the major isomers, δ - Toc was present in traces and β -Toc was never found. All taxa had a similar fatty acid composition with C 16:0 (357.2 mg kg − 1 DW), C 18:1 (393.94 mg kg − 1 DW) and C 22:1 (618.29 mg kg − 1 DW) acids present in higher amount. Unsaturated fatty acids (52.5–66.5%) were more abundant than saturated (33.5–47.5%) ones relative to the total f…

Purification and Characterization of Glutamine Synthetase Isoenzymes from Leaves and Roots of Brassica napus (L.)
1995
Summary The glutamine synthetase enzymes from leaves (GS2) and roots (GSR) of Brassica napus L. have been purified to homogeneity by the application of a three-stage isolation procedure comprising anion-exchange chromatography, adsorption by hydroxylapatite and gel filtration on Sephacryl 5-300 HR. The isoforms of the enzyme show a differential distribution in leaf and root tissues. Elution profiles of hydroxylapatite chromatography showed a distinct behaviour for GS proteins found in leaves and roots. Denaturing SDS-PAGE and Western blot experiments revealed molecular masses of approximately 43.5 and 40.5 kD for GS2 and GSR subunits, respectively. Moreover, kinetic properties determined us…
The Influence of Brassinosteroid, a Growth-promoting Steroidal Lactone, on Development and CO2-fixation Capacity of Intact Wheat and Mustard Seedlings
1984
In 1970, Mitchell et al. isolated a lipoidal complex from the pollen of rape (Brassica napus L.). This complex, called “Brassins” was found to have partly powerful growth-promoting properties. The novel growth response of young bean plants in the second internode assay (Worley, Mitchell 1971; Mitchell, Gregory 1972) and other physiological changes following Brassin-treatment have been studied under several aspects (Krizek, Worley 1981; Gregory 1981).

Water-soluble chlorophyll proteins (WSCP) from Brassicaceae form homotetrameric chlorophyll (Chl)–protein complexes binding one Chl per apoprotein and no carotenoids. Despite the lack of photoprotecting pigments, the complex-bound Chls displays a remarkable stability toward photodynamic damage. On the basis of a mutational study, we show that not only the presence of the phytyls is necessary for photoprotection in WSCPs, as we previously demonstrated, but also is their correct conformation and localization. The extreme heat stability of WSCP also depends on the presence of the phytyl chains, confirming their relevance for the unusual stability of WSCP.
