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...

Genome-wide analysis of LIM gene family in Populus trichocarpa, Arabidopsis thaliana and Oryza sativa Inra
Arnaud, D.; Dejardin, A.; Leplé, J.C.; Lesage Descauses, M.C.; Pilate, G..
In Eukaryotes, LIM proteins act as developmental regulators in basic cellular processes such as regulating the transcription or organizing the cytoskeleton. The LIM domain protein family in plants has mainly been studied in sunflower and tobacco plants, where several of its members exhibit a specific pattern of expression in pollen. In this paper, wefinely characterized in poplar six transcripts encoding these proteins. In Populus trichocarpa genome, the 12 LIMgene models identified all appear to be duplicated genes. In addition, we describe several new LIM domain proteinsdeduced from Arabidopsis and rice genomes, raising the number of LIM gene models to six for both species. PlantLIM genes have a core structure of four introns with highly conserved coding...

Identification et caractérisation de la famille de protéines à domaine LIM chez le peuplier Inra
Arnaud, D..
Les gènes LIM de plantes sont exprimés dans tous les tissus ou spécifiquement dans lepollen. Les protéines à domaine LIM de plantes auraient une double fonction cellulaireagissant comme facteur de transcription activant la synthèse de la lignine ou comme protéineliant et empaquetant les filaments d’actines. Ce travail de thèse présente la première étude dela famille de protéines à domaine LIM chez le peuplier. Six paires de gènes LIM ont étéidentifiées dans le génome séquencé de Populus trichocarpa, et la comparaison avec lesmodèles de gènes LIM d’Arabidopsis et de riz révèle une structure génomique très conservée.L’analyse de 155 unigènes LIM additionnels chez les plantes a permis de définir quatregroupes phylogénétiques distincts divisés en plusieurs...

Recent progress in the characterization of molecular determinants in the Xanthomonas axonopodis pv. manihotis-cassava interaction Inra
Verdier, V.; Restrepo, S.; Mosquera, G.; Jorge, V.; Lopez, C..
Cassava bacterial blight, caused by xanthomonas axonopodis pv. manihotis (Xam), is a widespread disease that affects cassava (Manihot esculenta Crantz). Studies on the pathogen population structure, pathogen diagnosis, identification and expression of plant genes involved in resistance have been carried out. Different molecular techniques were developed to assess the genetic diversity among the Xampopulations. Characterization of Xam population dynamics over time had enable us to determine the different factors that are associated with resistance breakdown and those that influence the genetic structure or virulence phenotypes of the pathogen’s population. Methods for detecting the pathogen in vegetative planting materials and true seeds were developed and...
