E. auteur aut IRD text journalArticle eng text/pdf born digital access Rice cultivation has drastically increased in Africa over the last decade. During this time, the region has also seen a rise in the incidence of rice bacterial blight caused by the pathogen Xanthomonas oryzae pv. oryzae. The disease is expanding to new rice production areas and threatens food security in the region. Yield losses caused by X. oryzae pv. oryzae range from 20 to 30% and can be as high as 50% in some areas. Employing resistant cultivars is the most economical and effective way to control this disease. To facilitate development and strategic deployment of rice cultivars with resistance to bacterial blight, biotechnology tools and approaches, including marker-assisted breeding, gene combinations for disease control, and multiplex-PCR for pathogen diagnosis, have been developed. Although these technologies are routinely used elsewhere, their application in Africa remains limited, usually due to high cost and advanced technical skills required. To combat this problem, developers of the technologies at research institutions need to work with farmers from an early stage to create and promote the integration of successful, low cost applications of research biotech products. Here, we review the current knowledge and biotechnologies available to improve bacterial blight control. We will also discuss how to facilitate their application in Africa and delivery to the field. specialized Xanthomonas oryzae Biotechnology Diversity Detection Resistance 076 159 4 320-328 2012 0168-1656 https://www.documentation.ird.fr/hor/fdi:010055918 10.1016/j.jbiotec.2011.09.020 0168-1656 [F B010055918] https://www.documentation.ird.fr/hor/fdi:010055918 https://www.documentation.ird.fr/intranet/publi/2012/06/010055918.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-07-04 2017-08-23 fdi:010055918 fre
