Welcome to the website of the TriLat Initiative on Stable Rice Supply in sub-Saharan Africa!

On June 15 and 16, the IRD Center in Montpellier was hosting the First TriLat Meeting on Stable Rice Supply in sub-Saharan Africa, supported by a grant from the Agence Inter-établissements de Recherche pour le Développement (AIRD), France, and the Federal Ministry of Education and Research (BMBF), Germany.

This trilateral initiative is coordinated by Dr Ralf KOEBNIK, (IRD Montpellier, UMR 186 "Résistance des Plantes aux Bioagresseurs" (France), Dr Jens BOCH, Martin-Luther-University Halle-Wittenberg (Germany), and Dr Léonard S. OUÉDRAOGO, INERA Bobo-Dioulasso (Burkina Faso).

First TriLat Meeting on Stable Rice Supply, IRD Center Montpellier, France, June 15-16, 2011

This was the first time that 16 scientists and university professors from six countries (France, Germany, Burkina Faso, Benin, Mali and Togo) met to discuss opportunities of collaboration and to develop a joint project to fight the most devastating bacterial diseases of rice which are caused by strains of Xanthomonas oryzae. Dr Jens Boch and colleagues did a break-through discovery to understand bacterial pathogenicity at the molecular level. The application of this discovery has been licensed by the Two Blades Foundation and life technologiesTM (Press Release from June 10, 2011) and will be used in the frame of this initiative.

The aim of the trilateral project is to establish a survey for Xanthomonas diseases on rice in West-Africa and to apply novel strategies to combat these diseases, thus supporting an increased rice production for these African countries.

The two-days meeting covered several topics, such as rice cultivation and bacterial diseases in sub-Saharan Africa, sampling and typing of Xanthomonas strains, genetic/omics resources and resistance genes of rice, the impact of key virulence factors of X. oryzae and their potential as guides for the development of novel resistances. The meeting also gave room to exchange views on the acceptance and applicability of GMOs, to discuss questions of intellectual property and to evaluate possibilities for capacity building in the sub-Saharan region.

This very stimulating and fruitful meeting will be succeeded by a second meeting in Burkina Faso by the end of July which will enable the submission of a grant proposal to AIRD and BMBF.
