Seed Research and Technical Cooperation with Brazil
The purpose of this project is to conduct joint seed research leading to enhanced opportunities for the conservation and sustainable use of plant genetic resources of Brazil, including through knowledge exchange.
Kew’s Seed Conservation Department has maintained active scientific engagement with Brazilian partners since the 1990s, and this has accelerated since 2006 with the supervision of several Brazilian postgraduate students, the provision of advanced seed morphology training, and associated technical engagement with government and university partners. The strongest research link has been with the Federal University of Lavras with whom 7 postgraduate students have been supervised (4 PhDs completed by September 2011). Since 2006, the collaboration has resulted in 10 publications in international peer-review journals
The related project "Morpho-physiological aspects of tree seeds from the Amazon and their implications on seed storage" with the National Institute for Amazonian Research (INPA) has enabled advanced morphology training to be provided to Brazilian students and a PhD student project on oxidative stress has been started. Researchers at São Paulo University (UNOESTE) and the Federal University of Parana (UFPR) have participated in the Darwin Initiative-supported project Orchid Seed Stores for Sustainable Use (OSSSU).
Future plans include the provision of advanced training in molecular aspects of seed dormancy, and the use of genomics in seed conservation. Technical cooperation will also be strengthened through the exchange of seed bank management experience with Cenargen-Embrapa and University partners that store seed for conservation, research and sustainable use purposes.
