“…Families with a high incidence of recalcitrant species which are less likely to be conserved in conventional seed banks are Fagaceae, Lauraceae, Sapotaceae, Moraceae, Clusiaceae, Sapindaceae (including Aceraceae), Arecaceae (= Palmae), Myrtaceae, Annonaceae, Rurtaceae, Anarcardiaceae, Dipterocarpaceae, Meliaceae and Rhizophoraceae (Dickie and Pritchard 2002). Some wild species have been found to produce seeds that are extremely short lived in traditional seed bank storage and cryopreservation may be the only resource to ensure the effective ex situ seed conservation of such species (Li and Pritchard 2009;Hay and Probert 2013). Li and Pritchard (2009) highlighted the need to increase our effort at developing ex situ conservation approaches for plants, particularly those from biodiversity hotspots with recalcitrant seeds.…”

“…There are more than 1750 seed banks in the world, the majority of which conserve crop diversity (Hay and Probert 2013). Since the Global Strategy for Plant Conservation (GSPC) was adopted by the Convention on Biological Diversity (CBD) in 2002, the number of ex situ conservation facilities for wild species has grown dramatically, but little information is available about the extent to which plant species are appropriately represented in ex situ collections (Godefroid et al 2011;Cibrian-Jaramillo et al 2013;Rivière and Mül-ler 2017;Teixido et al 2017).…”

The Millennium Seed Bank (MSB) Partnership, developed and managed by the Royal Botanic Gardens, Kew (RBG Kew), conserves propagules primarily from orthodox seed-bearing wild vascular plants. It is the largest ex situ conservation programme in the world, currently involving 96 countries and territories. Where possible, seeds are collected and conserved in the country of origin with duplicates being sent to RBG Kew's MSB for storage. In this paper we assess the conservation value of the germplasm stored at the MSB using both quantitative and qualitative methods. The MSB holdings represent a high quality, rich biological resource. Substantial and unique taxonomic diversity exists amongst the collections, representing 365 families, 5813 genera, 36,975 species and 39,669 taxa conserved. The collections cover a wide geographic range, originating from 189 countries and territories, representing all nine bio-geographic regions and all 35 biodiversity hotspots. The collections possess significant natural capital and population value: 32% of taxa, representing 49% of collections, have at least one identified use to humans; and 74% of taxa, representing 78% of collections, are either endemic, endangered (nationally or globally) and/or have an economic, ecological, social, cultural or scientific value. While 10% of taxa, representing > 8% of collections, are either extinct, rare or vulnerable to extinction at the global and/or national level, 20% of taxa, representing 13% collections, are endemic at the country or territory scale. Over the 17-year period since 2000 at least 11,182 seed Communicated by Daniel Sanchez Mata.This article belongs to the Topical Collection: Ex-situ conservation.

“…Present seed banks can provide a source and methodology for the propagation of this scale of seed provision. Acknowledging the increasing role of seed bank collections of wild species in reintroduction, Hay and Probert (2013) published a review to guide the management and use of wild species collections in seed banks.…”

“…Significant scientific value can be attributed to the botanical occurrence records of these repositories as well (Clark and Thompson 2004). Given the usually narrow window of opportunity to collect viable seeds of wild plants (Hay and Probert 2013), the date of collection has a high indicator value for the phenology of species in a given habitat for the given year. Other data types recorded during seed collection on e.g.…”

Seed bank collections have multiple benefits: store genetic material for conservation and research, and their data can also provide valuable scientific information. The Pannon Seed Bank was established during an EU LIFE+ project between 2010 and 2014 with the target to collect and store seeds of approx. 50% of the wild native vascular flora of the Pannonian Biogeographic Region, seed accessions of at least 800 storable species. This task was fully achieved by the end of the project, as altogether 1,853 seed accessions of 910 species are stored. The aim of the present paper is to provide access to the collection data and metadata of the Pannon Seed Bank as it was completed by the end of the project. The collection campaign involved about 40 experts and covered the whole country. Collection and storing applied standard methodology, based on the ENSCONET project. The collection data published in this paper can be used manifold. Geographical data on species occurrences are major input for nature conservation and research. Seed collection date is valuable for ecological studies of phytophagous insects, frugivorous birds and mammals, etc. The database can be partner to international databases (like GBIF) or research infrastructures (e.g. LifeWatch). Hopefully, this data paper will contribute to further motivate the development of native seed collections and their use for conservation and research in Hungary.

“…Thus, the collection of seeds of wild species, and their maintenance in ex-situ seed banks, should be included as an integrated tool along with in habitat plant conservation. Seed banks are facilities with a high technological content (Rao and Riley, 1994), which should take responsibility for the whole line of seed management all the way through to the reintroduction step (Hay and Probert, 2013).…”

Analysis of genetic structure of Ranunculus baudotii in a Mediterranean wetland. Implications for selection of seeds and seedlings for conservation

et al. 2015

a b s t r a c tSeed collection and storage of wild species in ex-situ seed banks should be continued as an integrated tool for the conservation of plants in their habitats. Although seed-bank facilities are widely used today, their seed samples often suffer low genetic diversity. Consequently, reintroduced seeds and plant material may not have the resilience to cope with future environmental stress so leading to complete wastage of seeds. Molecular techniques allow the benefit of quantification of the genetic diversity of a seed collection in comparison with that of the natural population. In this study we focus on ex-situ seed bank samples and living collections of Ranunculus peltatus subsp. baudotii. We compare their genetic diversity and structure with that of the natural population before and after undertaking a restoration project on a natural pond in the Tuscan Archipelago National Park. ISSR analyses, carried out on a total of five sampling groups, shows a relatively high level of genetic diversity for the ex-situ cultivated groups. The analysis of molecular variance, in agreement with clustering obtained in the neighbour-joining dendrogram and with the pattern from cluster analysis, suggests dividing the samples analysed into two groups: one formed by individuals sampled before the pond restoration and the other formed by the subsequent pond population. The results highlight the importance of planning mixed propagation lines which can be obtained through the use of a range of germination conditions to exploit a novel source of genetic variability which may otherwise remain hidden within the seed collection.
