- aggregation abstract "Worldwide about one third of all plant species is threatened with extinction. Botanical gardens play a key role in conservation of plant diversity, and as is stated in Target 8 of the GSPC, at least 75 % of threatened plant species should be present in ex situ collections. However, only about 30 % of globally threatened plant species are currently held in living collections. These have to be genetically representative, but information about the genetic diversity present in such collections is scarce, even for horticultural significant plants like cacti, although it is estimated that diversity is low in numerous species. Moreover, our knowledge about genetic diversity of threatened plant species in general is quite restricted. This lack of insight in genetic diversity of threatened plant species heavily contrasts with the broad knowledge about crops and their wild relatives. We still have a long way to go to study genetic diversity in threatened plants, conserve an important part of this diversity in ex situ collections, define which percentage of genetic diversity might be feasible and/or desirable to aim for, and finally, make this available for conservation and restoration projects. One of the aims of our PLAN(E)T project is the comparison of genetic diversity between wild populations and ex situ collections of the three Chilean cactus genera Copiapoa, Eriosyce and Eulychnia. A range of genomic tools (barcoding, microsatellites, AFLP, RAD sequencing) will be applied to wild and ex situ individuals of nine selected species to enable rapid characterisation of genetic variation, providing: (1) support for specific conservation actions, and (2) general guidelines and a protocol on genetic management for acquiring accessions for ex situ collections, to be used by collectors and botanical gardens worldwide in the framework of achievement of Target 8 of the GSPC. As a first step in the project, botanic gardens worldwide were queried for detailed information about their entire Copiapoa, Eriosyce and Eulychnia collections. This will allow us to investigate the global extent of living ex situ collections of these genera, to assess and discuss their usefulness for cultivation and restoration programs and inform priority actions for conservation of their threatened taxa.".
