QLK5-CT-2002-012791 November, 2002- 31 October, 2005 What is CRYMCEPT ??
What is cryopreservation ? • What ? • Storage of living tissues at ultra-low temperatures (-196°C) • Use • Conservation of plant germplasm • Vegetatively propagated species (root and tubers, ornamental, fruit trees) • Recalcitrant seed species (Howea, coconut, coffee) • Conservation of tissue with specific characteristics • Medicinal and alcohol producing cell lines • Genetically transformed tissues • Transformation/Mutagenesis competent tissues (embryogenic cell suspensions) • Eradication of viruses (Banana, Plum) • Conservation of plant pathogens (fungi, nematodes)
What is the ‘problem’ with plant cryopreservation ? • Cryopreservation procedures are now available for about 150-200 different plant species • But For each species and tissue type, the cryopreservation protocol needs to be empirically adapted in function of their • natural freezing resistance • explant size and type • water content • So no real standardised methods are available • Most of the work on cryopreservation of plants has been performed in the framework of academic studies and involves only one or a few genotypes. Only few plant germplasm collections stored in liquid nitrogen currently exist (with a relatively limited amount of accessions). • A more efficient optimisation of existing cryopreservation protocols and/or development of new protocols is only possible if the physico-chemical background of cryoprotection/tolerance towards dehydration is known.
Objectives General objective: The development of new/improved cryopreservation protocols applicable to plant germplasm collections in Europe. • Specific objectives: • Development of sensitive, reliable and use friendly techniques to measure plant species / tissue response to cryoprotection/cryopreservation. • Determination of physico-biochemical changes associated with tolerance towards cryopreservation. • Development of new plant cryopreservation protocols. • Validation of the improved cryopreservation protocols and their application to European germplasm collections.

How to maximize chance for success ? • Each Work package involves at least 2 partners. The Work package coordinator has already proven to have relevant and considerable experience with the analysis technique that is described in the Work package. • All partners 1- 6 are on average participating actively in 3 to 4 of the Work packages 1-7. This ensures, together with the yearly coordination meetings an efficient communication flow between the Work package groups. • The project covers a variety of the most relevant physico-biochemical parameters that could be related to cryoprotection. Nevertheless, at each yearly coordination meeting a discussion will be held to ensure that key issues will not fall between WPs. • The project involves a very broad spectrum of genotypes, species (monocots and dicots), different tissues (differentiated and dedifferentiated) with a differential response towards hardening (hardening not possible to complete hardening). As such, a series of generally applicable “core” cryopreservation will be established. These will be applicable to germplasm which display different sensitivities and tolerances (e.g. cold tolerant, desiccation sensitive)
