CARATTERIZZAZIONE DELLE EUFORBIE DELLA FLORA SICILIANA TRAMITE “DNA BARCODING”
2013
Il genere Euphorbia L. in Sicilia comprende 36 taxa (1, 2) di cui 8 endemici e subendemici, 21 a distribuzione mediterranea, 5 europea e 2 ancora più ampia. Si tratta di entità presenti nei più svariati contesti ecologici, aventi in comune una caratteristica tossicità derivante dalla presenza di vari alcaloidi più o meno concentrati nel latice. Alcune euforbie sono tipiche della macchia mediterranea, altre si rinvengono nell’ambito di formazioni prative e forestali di alta quota, alcune sono casmofite, altre psammofite. In particolare, le entità native in Sicilia sono: E. akenocarpa Guss., E. aleppica L., E. biumbellata Poir., E. bivonae Steud., E. ceratocarpa Ten., E. characias L., E. cora…
Assessing the use of the mitochondrial cox1 marker for use in DNA barcoding of red algae (Rhodophyta)
2011
The red algae, a remarkably diverse group of organisms, are difficult to identify using morphology alone. Following the proposal to use the mitochondrial cytochrome c oxidase subunit 1 (cox1) for DNA barcoding animals, we assessed the use of this, ne in the identification of red algae using 48 samples plus 31 sequences obtained from GenBank. The data set spanned six gene orders of red algae: the Bangiales, Ceramiales, Corallinales, Gigartinales, Gracilariales and Rhodymeniales. The results indicated that species could be discriminated. Intraspecific variation was between 0 and 4 bp over 539 bp analyzed except in Mastocarpus stellatus (0-14 bp) and Gracilaria gracilis (0-11 bp). Cryptic dive…
DNA barcoding for Arecaceae and Fabaceae species identification of two plant collections
2021
DNA barcoding is a well-known technique that enable species identification by using universal DNA sequences from a small fragment of the genome. In this work, the effectiveness of DNA barcoding approach was evaluated in order to identify different taxonomic groups among two families (Arecaceae and Fabaceae) from two flowering plant collections: some were economically important taxa from nursery production and Mediterranean plants with ornamental attitude for possible new introduction. Three chloroplast DNA barcode regions (matK, rbcL and trnH-psbA) proposed by the Consortium for the Barcode of Life (CBOL) were tested in 22 Arecaceae species and in eight Fabaceae species, including Ceratonia…
An integrated approach to the study of Hypericum occurring in Sicily
2020
An integrated approach to the study of taxa of the genus Hypericum occurring in Sicily is proposed. The results of morphological, biochemical, and molecular analyses are combined to better assess the relationships between the species investigated and test the suitability of DNA barcoding technique in the discrimination of these taxa. For the name Hypericum aegypticum subsp. webbii (Spach) N. Robson a lectotype is designated. For Hypericum triquetrifolium Turra a lectotype and a supporting epitype are designated. The presence of Hypericum perforatum L. subsp. perforatum is excluded from Sicily and the previous reports have to be referred to H. perforatum subsp. veronense (Schrank) Ces. Hyper…
Aplicación de técnicas morfológicas y moleculares en la identificación de la megalopa de decápodos braquiuros de la península ibérica
2015
Entre los crustáceos decápodos, el Infraorden Brachyura Linnaeus, 1758 es el grupo más diverso y de mayor éxito evolutivo, con aproximadamente 7.000 especies pertenecientes a 98 familias (Tsang et al. 2014). Los braquiuros, comúnmente llamados cangrejos, han conquistado casi todos los hábitats y numerosos nichos ecológicos (De Grave et al. 2009; Ahyong et al. 2011). La mayoría de las especies son marinas, aunque también existen especies de agua dulce o incluso especies terrestres. El desarrollo larvario de los braquiuros suele constar de dos fases de vida libre y planctónicas (con las escasas excepciones de aquellos con desarrollo directo, principalmente de agua dulce): zoea (con varios est…
Assessing the effect of chromium pollution on benthic foraminiferal community: morphological vs. environmental metabarcoding approaches
The purpose of this experimental study is to assess the impact of different concentrations of chromium (Cr) through time on the diversity of cultured benthic foraminifera combining two morphological approaches for the identification of living specimens that are Rose Bengal (RB) staining and CellTracker Green (CTG) labelling as well as environmental DNA and RNA metabarcoding. Seven tanks/aquaria with different concentrations of Cr in water, namely 100 ppt, 1 ppb, 10 ppb, 100 ppb, 1 ppm and 10 ppm plus the control were used. A mesocosm was extracted from each tank at pre-established time (1 week, 2 weeks, 4 weeks 6 weeks and 8 weeks). Morphological analyses produced 6 datasets based on staini…
