RNA-Mediated Resistance to Cassava Geminiviruses in Transgenic Cassava
Cassava mosaic disease (CMD) is one of the major problems encountered in cassava fields in Africa where the disease can trigger overall yield losses up to 25%. CMD is caused by whitefly-transmitted geminiviruses. Synergism, recombination and pseudo-recombination between different cassava geminivirus species have led to the recent pandemics of severe CMD in Africa (Legg and Fauquet, 2004). Our research aims at developing different CMD prevention strategies in transgenic cassava and therefore providing local farmers with geminivirus resistant lines to secure cassava production in the subsistence faming system.
