“…The local grapevine germplasm from regions of warm and dry climate may serve as an alternative. Exploration and agronomic evaluation of the indigenous diversity for heat-stress-tolerant varieties or clones would be of particular importance for the sustainability of viticulture and the wine industry [ 25 , 92 ].…”

“…Several wine-growing regions in southern Europe have already reached or even exceeded optimum thermal conditions for the currently cultivated varieties [ 25 ]. Fraga et al [ 26 ] referred to recent elevated temperatures during grape berry maturation in the Iberian Peninsula, indicating a possible diminishing of wine quality in the near future.…”

The potential effects of the forthcoming climate change include the rising of the average annual temperature and the accumulation of extreme weather events, like frequent and severe heatwaves, a phenomenon known as global warming. Temperature is an important environmental factor affecting almost all aspects of growth and development in plants. The grapevine (Vitis spp.) is quite sensitive to extreme temperatures. Over the current century, temperatures are projected to continue rising with negative impacts on viticulture. These consequences range from short-term effects on wine quality to long-term issues such as the suitability of certain varieties and the sustainability of viticulture in traditional wine regions. Many viticultural zones, particularly in Mediterranean climate regions, may not be suitable for growing winegrapes in the near future unless we develop heat-stress-adapted genotypes or identify and exploit stress-tolerant germplasm. Grapevines, like other plants, have developed strategies to maintain homeostasis and cope with high-temperature stress. These mechanisms include physiological adaptations and activation of signaling pathways and gene regulatory networks governing heat stress response and acquisition of thermotolerance. Here, we review the major impacts of global warming on grape phenology and viticulture and focus on the physiological and molecular responses of the grapevine to heat stress.

“…In developing countries, the importance of agrobiodiversity and local seed systems is likely to further grow, given the forecasted increase in human population, shifts towards urbanized areas and changed environmental conditions (Cleveland et al 1994;Bretting and Duvick 1997;Banilas et al 2009;Abay et al 2011;Jalloh et al 2012). In developed countries, the awareness of the importance of agrobiodiversity is growing, both from a conservation biology point of view and in anticipation of fossil fuel shortages (Fess et al 2011;Rudd 2011b;Tilman et al 2011;Pautasso 2012;Portis et al 2012).…”

The circulation of seed among farmers is central to agrobiodiversity conservation and dynamics. Agrobiodiversity, the diversity of agricultural systems from genes to varieties and crop species, from farming methods to landscape composition, is part of humanity's cultural heritage. Whereas agrobiodiversity conservation has received much attention from researchers and policy makers over the last decades, the methods available to study the role of seed exchange networks in preserving crop biodiversity have only recently begun to be considered. In this overview, we present key concepts, methods, and challenges to better understand seed exchange networks so as to improve the chances that traditional crop varieties (landraces) will be preserved and used sustainably around the world. The available literature suggests that there is insufficient knowledge about the social, cultural, and methodological dimensions of environmental change, including how seed exchange networks will cope with changes in climates, socio-economic factors, and family structures that have supported seed exchange systems to date. Methods available to study the role of seed exchange networks in the preservation and adaptation of crop specific and genetic diversity range from meta-analysis to modelling, from participatory approaches to the development of bio-indicators, from genetic to biogeographical studies, from anthropological and ethnographic research to the use of network theory. We advocate a diversity of approaches, so as to foster the creation of robust and policy-relevant knowledge. Open challenges in the study of the role of seed exchange networks in biodiversity conservation include the development of methods to (i) enhance farmers' participation to decision-making in agro-ecosystems, (ii) integrate ex situ and in situ approaches, (iii) achieve interdisciplinary research collaboration between social and natural scientists, and (iv) use network analysis as a conceptual framework to bridge boundaries among researchers, farmers and policy makers, as well as other stakeholders.

“…The present work aims at studying the true-to-type genetic identity of 'Ribolla Gialla' accessions from private vineyards, grape collection and nurseries in Friuli Venezia Giulia and to compare 'Ribolla Gialla' with Ribolla-like white grape varieties cultivated in Slovenia (namely 'Rebula' and 'Glera') and in the Greek Ionian Island of Kefalonia (namely 'Robola') (Banilas et al, 2009). All three varieties are often considered to have a common origin, and 'Rebula' has been suggested to be identical to 'Ribolla Gialla', while 'Robola' was supposed to derive from the 'Ribolla Gialla' being introduced in Greece by the Venetians (Costacurta, 1978).…”
