tailieunhanh - Morphological, chemical, and genetic diversity of wild myrtle (Myrtus communis L.) populations in Sicily
Myrtus communis L. is a shrub widespread in the Mediterranean area. The interest in this species is growing, mainly due to its pharmacological and aromatic properties. The overexploitation of wild populations induced increasing degradation of plant cover with serious risk of loss of genetic diversity. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2016) 40: 249-261 © TÜBİTAK doi: Research Article Morphological, chemical, and genetic diversity of wild myrtle (Myrtus communis L.) populations in Sicily 1, 2 2,3 2 2 Sara MELITO *, Salvatore LA BELLA , Federico MARTINELLI , Ignazio CAMMALLERI , Teresa TUTTOLOMONDO , 2 4 4 5 Claudio LETO , Angela FADDA , Maria Giovanna MOLINU , Maurizio MULAS 1 Department of Agriculture, University of Sassari, Italy 2 Department of Agricultural and Forest Sciences, University of Palermo, Italy 3 Euro-Mediterranean Institute of Science and Technology (IEMEST), Palermo, Italy 4 Institute of Sciences of Food Production, National Research Council, Sassari, Italy 5 Department of Nature and Land Sciences, University of Sassari, Italy Received: Accepted/Published Online: Final Version: Abstract: Myrtus communis L. is a shrub widespread in the Mediterranean area. The interest in this species is growing, mainly due to its pharmacological and aromatic properties. The overexploitation of wild populations induced increasing degradation of plant cover with serious risk of loss of genetic diversity. This research explored the morphological, chemical, and genetic diversity of wild myrtle populations in Sicily, with the aim to provide a first characterization of a core collection of 36 accessions from 7 localities for future domestication programs. Amplified fragment length polymorphism fingerprinting generated 152 polymorphic fragments. STRUCTURE analysis identified three genetic clusters (A, B, and C) corresponding to specific geographical origin. Analysis of molecular variance estimated a quite high overall fixation index (FST = ). Misilmeri and Ispica were the more divergent populations (FST = ), while M. Pellegrino and Scopello revealed the lowest FST (). The relationships between genetic, morphological, and
