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).

PNG sweet potato improvement project
This just in from Mr Patrick S. Michael, a PNG scientist who's just off to the University of Nottingham in the UK to work on sweet potato improvement. If you have any comments or advice you can contact Patrick on email@example.com. Very best wishes to Patrick!
In the light of plant tissue culture, biotechnology and genetic engineering, my project aims at developing sweet potatoes varieties that are tolerant to frost damage thereby introducing antifreeze genes into the genomes of the drought tolerant sweet potato cultivars using the techniques of genetic transformation (engineering) aiming at making sweet potato production more stable, productive and continuous at the same time maintaining genetic diversity, identify cultivars and establish a comphrensive core collection.
I also look at developing useful, flexible, precise transformation methods for crop improvement and research techniques that could be expolated to management of other plant genetic resources, which should allow breeders, researchers and the authority to adopt for creating core collection of the germplasm, generating new improved varieties, registration of varieties and intellectual protection and tracing germplasm for benefit sharing.
Part of the work could include developing National Biosafety Framework (NBF) for PNG and to increase understanding of information gathering and analysis, stakeholders consultation, risk assessment procedures, mechanisms for sharing of risk assessment and management experiences, implications for risk assessment and decision-making at national levels, systems for public participation and information, networking to share lessons and experiences, and opportunities for collaboration to deal with the GMOs and the products of biotechnology in PNG.
Sweet potato samples were collected from NARI-Aiyura and tissue cultured at the Unitech Biotech Center Tissue Culture Facilities and ready to be taken to the University of Nottingham, United Kingdom were most of the genetic engineering work will be done. The materials have qualified UK and PNG quarantine. Part of the project will include searching for the low temperature genes (-20C) in a known biological sources and identifying a suitable vector for DNA uptake and integration into the host cells.
Upon successful transformation and development of evaluation and risks assessment procedures and consultation with the PNG Government, SPC and stakeholders, evaluation trials will be carried out in the highlands of PNG to test their ability to withstand real low temperatures.
The study has been funded by the Commonwealth Government of the United Kingdom, under the Central Chevening Funds and will run for about 18 months. My projects starts on the 20th September 2004 and I will be leaving for United Kingdom on the 12th of September, 2004.
