Evaluation of the DNA barcoding approach to develop a reference data-set for the threatened flora of Sicily
2014
The Mediterranean Basin is one of the most significantly altered World Biodiversity Hotspots with extensive habitat loss and fast genetic population erosion, for which urgent biodiversity reconnaissance and preservation actions are required. In particular, Sicily has about 600 taxa classified as threatened or near-threatened. The correct recognition and identification of such biodiversity is required for supporting further activities. The objective of this work is to assess the ability of the DNA barcoding approach to identify different taxonomic groups from a collection of the most threatened plant taxa, throughout natural Sicilian populations. The evaluation of the DNA barcoding core mark…
Ocena przydatności loci barkodowych do identyfikacji gatunków roślin łąk i muraw kserotermicznych. Komunikat
2020
Analiza sekwencji kilku loci nosząca nazwę barkodingu, została wykorzystana do identyfikacji gatunków roślin występujących w środkowoeuropejskich zbiorowisk traworoślowych. W toku analizy przebadano użyteczność 14 regionów chloroplastowych i jednego jądrowego do identyfikacji gatunków. Osiem spośród nich (matK, rbcL, rpoC1, trnH-psbA, atpF-atpH, trnL, psbI-psbK i ITS) wykorzystano do stworzenia kombinacji barkodów, które umożliwiają określenie tożsamości próbki tkanki roślinnej o pochodzeniu łąkowym, bez konieczności porównania z kluczem do oznaczania roślin.
Evolution, ecology and systematics of Soldanella (Primulaceae) in the southern Apennines (Italy)
2015
Background The populations of Soldanella (Primulaceae) of the southern Apennines (Italy) are unique within the genus for their distribution and ecology. Their highly fragmented distribution range, with three main metapopulations on some of the highest mountains (Gelbison, Sila and Aspromonte massifs) of the area, poses intriguing questions about their evolutionary history and biogeography, and about the possibility of local endemisms. Aims and methods In order to clarify the phylogeny and biogeography of the three metapopulations of Soldanella in the southern Apennines, attributed to S. calabrella to date, and to identify possible local endemisms, a comparative approach based on the study o…
Molecular phylogenetics of Melastomataceae and Memecylaceae: implications for character evolution
2001
Melastomataceae are among the most abundant and diversified groups of plants throughout the tropics, but their intrafamily relationships and morphological evolution are poorly understood. Here we report the results of parsimony and maximum likelihood (ML) analyses of cpDNA sequences from the rbcL and ndhF genes and the rpl16 intron, generated for eight outgroups (Crypteroniaceae, Alzateaceae, Rhynchocalycaceae, Oliniaceae, Penaeaceae, Myrtaceae, and Onagraceae) and 54 species of melastomes. The sample represents 42 of the family’s currently recognized ~150 genera, the 13 traditional tribes, and the three subfamilies, Astronioideae, Melastomatoideae, and Memecyloideae (= Memecylaceae DC.).
