This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific.
The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR.
SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).

Cryopreservation training for RGC staff
Rajnesh Sant of the SPC Regional Germplasm Centre attended a training course on cryopreservation from 12-22 September 2005 at the Laboratory of Tropical Crop Improvement, Katholieke Universiteit Leuven, Belgium. Below are some details.
Until recently, cryopreservation protocols were mostly developed following an empirical, trial-and-error approach. This led cryopreservation specialists in Europe and elsewhere to develop various analytical techniques to better describe and understand the biophysical and metabolic processes underlying resistance/sensitivity of plant tissues to cryopreservation. This new approach ensured the development of cryopreservation protocols in a more rational, scientific and cost-effective manner. In 2002 a project entitled “Establishing Cryopreservation Methods for Conserving European Plant Germplasm Collections” (CRYMCEPT) was funded by the European Union (contract number QLK5-CT-2002- 01279) to address an urgent need to develop cryopreservation techniques and protocols for important European plant genetic resources that could not be adequately conserved using conventional methods.
Members of the consortium established in the framework of the CRYMCEPT project include seven European institutions with expertise in different analytical techniques of relevance to cryopreservation. These include research on water thermal behaviour, proteins, sugars, membrane components, polyamines, cytoskeletal proteins and oxidative stress. The uniqueness of the CRYMCEPT project lies with the fact that experts in all these different areas work together to investigate nine target species selected using several analytical tools in parallel. This approach allows faster progress both in the understanding of the mechanisms involved in cryopreservation of plant tissues and in the establishment of cryopreservation protocols for other plant species. More information about the CRYMCEPT project can be found on the project website: www.agr.kuleuven.ac.be/dtp/tro/crymcept/.
The project organized a training workshop to disseminate the results of the research carried out in the project to develop optimal cryopreservation techniques for a number of plants, such as garlic, olive, Ribes, apple, almond, potato, banana and coffee. The workshops aimed to benefit germplasm collection holders in Europe, as well as from the EU international co-operation programme target countries. It was organized by the International Plant Genetic Resources Institute (IPGRI) in collaboration with the partners of the CRYMCEPT project:
