Collecting and maintaining exceptional species in tissue culture and cryopreservation. In: Falk, D., Holsinger, K., Wieland, G., Olwell, P., et al., editors. CPC Best Plant Conservation Practices to Support Species Survival in the Wild. Washington, D.C.: Island Press. p. 4-21. Interpretive Summary: n/a Technical Abstract: Exceptional plants are those that cannot be conserved long-term using conventional seed banking methods. This includes species producing few or no seeds for banking, species producing seeds that are intolerant of desiccation and freezing, or seeds that can tolerate drying, but not freezing, or species that produce seeds that may only tolerate storage at -20C for less than 10 years. For ex situ conservation, such species require methods alternative to conventional storage, such as cryopreservation or in vitro methods. Many of the world's plant species may fit these storage categories. The primary purpose of a conservation collection for an exceptional species is to support the species survival and reduce its extinction risk. Therefore accurate records of provenance, differentiated maternal lines and diverse genetic representation are prerequisites. |
