Abstract: Cassava (Manihot esculenta Crantz) is one of the most important staple crops in the tropics. It is growm for its tuberous roots, which provide food for over 500 million people. Because of its hardiness, tolerance to adverse environmental conditions and its flexible harvesting time, it plays and integral part in food security in developing countries. Cassava yields are, however, severely reduced by various insect pests and diseases. Traditional breeding of cassava is difficult, so biotechnology provides a valuable tool for genetic crop improvement. In our laboratory a method for producing transgenic cassava plants has been developed by combining direct shoot organogenesis from somatic cotyledon explants and Agrobacterium-mediated gene transfer. We have started applying the transformation technique transfering agriculturally relivant genes to cassava. The most devastating disease in all African food crops is African cassava mosaic virus disease. It is caused by African cassava Mosaic Virus (ACMV) and can cause local losses of up to 80%. So far there is no method available to protect the plants in the field from the virus. Our aim is to develop and evaluate methods for producing genetically improved cassava varieties resistant to ACMV, which will be able to grow and produce high yields under severe ACMV infection pressures. In order to achieve the suppression of virus replication, the effect of the expression of viral antisense RNAs as 3'-UTRs of a selectable marker gene, of truncated viral gene products and of defective interfering DNA will be assessed.
