Abstract
There is a pressing need to conserve plant diversity to prevent extinctions and to enable sustainable use of plant material by current and future generations. Here, we review the contribution that living collections and seed banks based in botanic gardens around the world make to wild plant conservation and to tackling global challenges. We focus in particular on the work of Botanic Gardens Conservation International and the Millennium Seed Bank of the Royal Botanic Gardens, Kew, with its associated global Partnership. The advantages and limitations of conservation of plant diversity as both living material and seed collections are reviewed, and the need for additional research and conservation measures, such as cryopreservation, to enable the long-term conservation of 'exceptional species' is discussed. We highlight the importance of networks and sharing access to data and plant material. The skill sets found within botanic gardens and seed banks complement each other and enable the development of integrated conservation (linking in situ and ex situ efforts). Using a number of case studies we demonstrate how botanic gardens and seed banks support integrated conservation and research for agriculture and food security, restoration and reforestation, as well as supporting local livelihoods.

Abstract
Fern spores and pollen are haploid plant germplasm of microscopic nature that can be used to regenerate full plants through germination (fern spores) or to fertilize seed-bearing plants through breeding programs (pollen). Due to their short life span in conventional storage (i.e., dry at -20 °C), the use of cryopreservation has been indicated for long-term ex situ conservation. While fern spores of most species and pollen from many seeded plants tolerate desiccation and can be stored dry at liquid nitrogen temperatures, some pollen is desiccation sensitive, and cryopreservation protocols require controlled drying and cooling and some level of cryoprotection. In this chapter we describe the cryopreservation process for fern spores used in the Millennium Seed Bank of Royal Botanic Gardens, Kew, including some details of the fern spores harvest and cleaning methods. In addition, two protocols for pollen cryopreservation are described, one generic for desiccation-tolerant pollen that can be used for multiple species and one specific for a desiccation sensitive pollen (Zea mays).
