Phytotoxicity of cardoon (Cynara cardunculus) allelochemicals on standard target species and weeds.
Journal of Agricultural and Food Chemistry, 2014Co-Authors: Carlos Rial, Paula Novaes, Rosa M. Varela, José M. G. Molinillo, Francisco A. MacíasAbstract:Cardoon (Cynara cardunculus L.) is a native plant to the Iberian Peninsula and the European Atlantic coast and invasive in American environments. Different solvents were used to perform cardoon extracts that were tested in phytotoxic bioassays. The ethyl acetate extract had the highest inhibitory activity so this was tested on the germination and growth of standard target species (lettuce, watercress, tomato, and onion) and weeds (barnyardgrass and brachiaria). The ethyl acetate extract was very active on root growth in both standard target species and weeds and it was therefore fractionated by chromatography. The spectroscopic data showed that the major compounds were sesquiterpene lactones. Aguerin B, grosheimin, and cynaropicrin were very active on etiolated wheat coleoptile, standard target species, and weed growth. The presence of these compounds explains the bioactivity of the ethyl acetate extract. The strong phytotoxicity of these compounds on important weeds shows the potential of these compounds...

Mining SNPs and Linkage Analysis in Cynara cardunculus
Genomics of Plant Genetic Resources, 2013Co-Authors: Sergio Lanteri, Alberto Acquadro, Davide Scaglione, Ezio PortisAbstract:Cynara cardunculus L., a member of the Asteraceae family, is a diploid (2n = 34) outcrossing perennial species native to the Mediterranean basin. It includes globe artichoke (var. scolymus L.), which today is grown as vegetable all over the world, cultivated cardoon (var. altilis DC), locally grown in Southern European countries, and their progenitor wild cardoon (var. sylvestris Lam). The species is also a valuable source of pharmaceutical compounds, and is exploitable for the production of lignocellulosic biomass as well as oil from seed, the latter being suitable for both edible and bio-fuel end-uses.

Isolation and functional characterization of a cDNA coding a hydroxycinnamoyltransferase involved in phenylpropanoid biosynthesis in Cynara cardunculus L
BMC plant biology, 2007Co-Authors: Cinzia Comino, Ezio Portis, Alberto Acquadro, Sergio Lanteri, Annalisa Romani, Alain Hehn, Romain Larbat, Frédéric BourgaudAbstract:Background Cynara cardunculus L. is an edible plant of pharmaceutical interest, in particular with respect to the polyphenolic content of its leaves. It includes three taxa: globe artichoke, cultivated cardoon, and wild cardoon. The dominating phenolics are the di-caffeoylquinic acids (such as cynarin), which are largely restricted to Cynara species, along with their precursor, chlorogenic acid (CGA). The scope of this study is to better understand CGA synthesis in this plant.

Development and characterization of microsatellite markers in Cynara cardunculus L.
Genome, 2005Co-Authors: Alberto Acquadro, Ezio Portis, David Lee, Paolo Donini, Sergio LanteriAbstract:Cynara cardunculus L. is a species native to the Mediterranean basin that comprises 2 crops, globe artichoke (var. scolymus L.) and cultivated cardoon (var. altilis DC), as well as wild cardoon (var. sylvestris (Lamk) Fiori). Globe artichoke represents an important component of the South European agricultural economy but is also cultivated in North Africa, the Near East, South America, the United States, and China. Breeding activities and molecular marker studies have been, to date, extremely limited. Better knowledge of the genome of the species might be gained by developing a range of molecular markers. Here, we report on the development of 14 microsatellites (simple sequence repeats (SSRs)) through a novel approach that we have defined as the microsatellite amplified library (MAL). The approach represents a combination of amplified fragment length polymorphism and a primer extension based enriched library, is rapid, and requires no hybridization enrichment steps. The technique provided a ~40-fold incre...

M‐AFLP‐based protocol for microsatellite loci isolation in Cynara cardunculus L. (Asteraceae)
Molecular Ecology Notes, 2005Co-Authors: Alberto Acquadro, Ezio Portis, Emidio Albertini, Sergio LanteriAbstract:Nine microsatellite markers for Cynara cardunculus L. were developed using a two-step ‘primer extension’ procedure, based on microsatellite-amplified fragment length polymorphism (M-AFLP) technique. In the first step, highly enriched SSR gel profiles were produced and, from the derived sequences of selected bands, forward primers directed towards the microsatellite motif were designed. In the second step, the opposite microsatellite flanking sequence was isolated using a nested approach on a restricted-ligated genomic fraction. Polymorphism was explored in 24 plants of wild cardoon ( Cynara cardunculus L. var. sylvestris ) as well as two accessions of both globe artichoke ( Cynara cardunculus L. var. scolymus ), and cultivated cardoon ( Cynara cardunculus L. var. altilis ).

isolation of microsatellite loci in artichoke Cynara cardunculus l var scolymus
Molecular Ecology Notes, 2003Co-Authors: Alberto Acquadro, Ezio Portis, Sergio LanteriAbstract:We report the development of nine microsatellite markers in globe artichoke (Cynara cardunculus L. var. scolymus). Four markers were obtained from sequences available in GenBank and five were isolated using a biotin/streptavidin capture technique for (CA)n and (CT)n motifs directly from artichoke genomic DNA. Polymorphism was explored in 15 artichoke accessions that represent the genetic variation within cultivated varietal types. Inter-specific amplification was tested using cultivated cardoon (C. cardunculus L. var. altilis DC.) and wild cardoon (C. cardunculus L. var. sylvestris Lam.). Primers and conditions for polymerase chain reaction (PCR) amplification of detected loci are described.
