A unigene catalogue of 5700 expressed genes in cassava Inra
Lopez, C.; Jorge, V.; Piégu, B.; Mba, C.; Cortes, D.; Restrepo, S.; Soto, M.; Laudié, M.; Berger, C.; Cooke, R.; Delseny, M.; Tohme, J.; Verdier, V..
Two economically important characters, starch content and cassava bacterial blight resistance, were targeted to generate a large collection of cassava ESTs. Two libraries were constructed from cassava root tissues of varieties with high and low starch contents. Other libraries were constructed from plant tissues challenged by the pathogen Xanthomonas axonopodis pv. manihotis. We report here the single pass sequencing of 11 954 cDNA clones from the 5' ends, including 111 from the 3' ends. Cluster analysis permitted the identification of a unigene set of 5700 sequences. Sequence analyses permitted the assignment of a putative functional category for 37% of sequences whereas ~16% sequences did not show any significant similarity with other proteins present in...

An EST resource for cassava and other species of Euphorbiaceae Inra
Anderson, J.V.; Delseny, M.; Fregene, M.A.; Jorge, V.; Mba, C.; Lopez, C.; Restrepo, S.; Soto, M.; Piégu, B.; Verdier, V.; Cooke, R.; Tohme, J..
Cassava (Manihot esculenta) is a major food staple for nearly 600 million people in Africa, Asia, and Latin America. Major losses in yield result from biotic and abiotic stresses that include diseases such as Cassava Mosaic Disease (CMD) and Cassava Bacterial Blight (CBB), drought, and acid soils. Additional losses also occur from deterioration during the post-harvest storage of roots. To help cassava breeders overcome these obstacles, the scientific community has turned to modern genomics approaches to identify key genetic characteristics associated with resistance to these yield-limiting factors. One approach for developing a genomics program requires the development of ESTs (expressed sequence tags). To date, nearly 23000 ESTs have been developed from...

Genetic mapping of resistance to bacterial blight disease in cassava (Manihot esculenta Crantz) Inra
Jorge, V.; Fregene, M.A.; Duque, M.C.; Bonierbale, M.W.; Tohme, J.; Verdier, V..
Cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam), is a major disease of cassava (Manihot esculenta Crantz) in Africa and South America. Planting resistant varieties is the preferred method of disease control. Recent genetic mapping of an F1 cross (TMS 30572 2 CM 2177-2) led to the construction of the first molecular genetic map of cassava. To better understand the genetics of resistance to CBB, we evaluated individuals of the F1 cross for CBB resistance by controlled greenhouse inoculations and visually assessed symptoms on days 7, 15, and 30 days after inoculation, using a scale where 0 = no disease and 5 = maximum susceptibility. Five Xam strains were used: CIO-84, CIO-1, CIO-136, CIO-295, and ORST X-27. Area under the...
