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).

Cassava as carotenoid source?
The following is reprinted from CropBiotech Net, and shows another side of cassava.
In Potentiality of Cassava Cultivars as a Source of Carotenoids, Dr. Nagib Nassar of the University of Brazil and colleagues show that one of foremost food sources of several tropical countries also has the potential to curb malnutrition. Their findings are published in the online journal Gene Conserve for March 2005.
In their experiments, the researchers screened cassava clones and interspecific hybrids, and, through colorimetric methods, found that a clone named UnB-400 contained high levels of lutein and trans-B-carotene. UnB-400 was found to have 236 mg/g of lutein, compared to zero in other cultivars; and 2.2 mg/g of trans-B-carotene, which is considered sufficient for the average daily requirements of adults consuming half a kilogram of cassava daily.
Both lutein and beta-carotene are potential antioxidants. Beta-carotene, in particular, is the precursor of Vitamin A, and has been shown to prevent heart disease and cancer, and lower the incidence of cataracts and macular disorders. Cassava, for its part, is both a cheap and abundant crop, and the Brazilian government is currently seeking ways to incorporate it into local wheat flours for enhanced flavor and nutrition.
