Genetic diversity of Mediterranean cattle breeds related to geography and climate
2015
In recent decades, changes in climate have caused impacts on natural and human systems. Mediterranean countries will be particularly affected by this phenomenon, with growing temperatures and reduced rainfall. Understanding how species and ecosystems respond to climate change has become a crucial focus in biodiversity conservation and management. The genome-wide SNP panels allows providing background information on genome structure in domestic animals, opening new perspectives to livestock genetics. The International Project GALIMED "Genetic Adaptation of Bovine Livestock and production systems in MEDiterranean region", develops an integrated approach that combines the analysis of SNP marke…
High-density single nucleotide polymorphism markers reveal the population structure of 2 local chicken genetic resources
2023
Italy counts a large number of local chicken populations, some without a recognized genetic structure, such as Val Platani (VPL) and Cornuta (COS), which represent noteworthy local genetic resources. In this study, the genotype data of 34 COS and 42 VPL, obtained with the Affymetrix Axiom600KChicken Genotyping Array, were used with the aim to investigate the genetic diversity, the runs of homozygosity (ROH) pattern, as well as the population structure and relationship within the framework of other local Italian and commercial chickens. The genetic diversity indices, estimated using different approaches, displayed moderate levels of genetic diversity in both populations. The identified ROH h…
The conservation of the Italian Crop Wild Relatives in the RIBES seed-banks: first data to establish national inventories and conservation priorities.
2016
The authors present the updated results of such census in the Italian Seed Bank Network for native species conservation (RIBES) with an analysis of the contribution to the conservation of the Italian FAO priority CWR. Finally, a national priority list for conservation of CWRs was drawn up and proposed here.
The conservation of the endemic Crop Wild Relatives in the RIBES seed-banks: towards a national priority list for the Italian CWRs
2016
Data of 620 crop wild relatives of species of food and fodder interest listed in the Annex I of the FAO Treaty (FAO, 2001) were collected within the census carried out by ISPRA, the Italian National Institute for Environmental Protection and Research, in 2014-2015 in order to quantify the extent of CWR representation in the Italian ex situ collections. According to such census, the RIBES network preserve 37% of the Italian CWRs listed in the FAO Treaty: in 14 out of 16 seed-banks are preserved 6,029 accessions of 229 CWR taxa, belonging to 11 families and 57 genera.

Seed germination in Abies nebrodensis (Pinaceae)
2019
Abies nebrodensis is a strict Sicilian endemic species, listed as “Critically Endangered” in the IUCN Red List of Threatened Species. Seed production highly varies annually and among specimens. The species is affected by a very low seed germination rate, mainly depending on the large number of empty seeds (from 68 to 96%). The embryo presence in seeds increases with increasing seed size and weight. Optimal germination rate (61%) was achieved at constant 5°C in the darkness. The low proportion of embryos in seeds is a relevant threat for A. nebrodensis conservation, as it affects the intrapopulation genetic diversity and reduces the potential genetic variability of seed accessions preserved …
Development of Sicilian bean core collection using morphological descriptors
2018
Different species and varieties of bean, spread in Sicily, are representative of local agricultural practices, as result of a careful exploration. Many landraces have become obsolete due to the spread of commercial varieties, but are still cultivated in small areas of Nebrodi Mountains (ME-Italy) and are endangered. The Sicilian bean landraces are often poorly known but represent a genetic heritage to be preserve and to enhance. The ex situ conservation of Sicilian bean landraces was carried out in “Living Plants Germplasm Bank” of Ucria (ME-Italy), founded by the Nebrodi Regional Park, and in “Sicilian Plant Germplasm Repository” of STEBICEF Department - University of Palermo. Within ex si…
Plant Conservation Centres in Sicily: The ‘Valle Maria’ Regional Centre (Godrano, Palermo) and the case study of the rare Centaurea erycina (Asterace…
2017
The role of the ‘Valle Maria’ Regional Centre and its activity in plant conservation thank to the collaboration with the University of Palermo, Dept. STEBICEF is discussed. The case study on propagation of Centaurea erycina, a narrow Sicilian endemic is presented.
The Seedbank database of the Hortus Botanicus Panormitanus
2012
A database for the management of the Seedbank of the Palermo’s Botanical Garden has been set up. Its structure and functioning are illustrated. Since November 2010 about 2000 records relating to 460 taxa have been inputted and are accesible via web. Links with other seedbank databases and with the database of the Herbarium Mediterraneum Panormitanum and of the Palermo’s Botanical Garden are explained.
THE BOTANICAL GARDEN “BERNARDINO DA UCRIA” IN THE NATURAL PARK OF THE NEBRODI (SICILY) AND ITS MISSION TO CONSERVE, EXPLOIT AND SPREAD LOCAL AGROBIOD…
2016
In Sicily, the academic botanical gardens of Catania, Messina and Palermo have been historically exerting a multiplicity of activities ranging from maintenance of ex situ collections to plant conservation policy, practice and ecological restoration, along with more traditional functions related to education and academic research. In the last decade’s, two new botanical gardens the “Nuova Gussonea” and the “Bernardino da Ucria, were created in Sicily, with the aim to play more delimited, yet modern and complementary roles. The garden “Nuova Gussonea”, within the Etna Natural Park, is mostly devoted to collect and preserve the native flora of the Mount Etna, with a special focus on endemic an…
