| 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... |

| 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... |

| Comparative QTL mapping for adaptive traits among populations and species can lead to the identification of genomic regions conserved over a long evolutionary period and therefore potentially harboring genes of great importance for adaptive processes. At the same time, non-conserved QTLs could be responsible for local adaptation or interspecific differentiation.The availability of Populus as a model system for tree and woody perennial plant biology has largely been driven by the rapid development of genomic and molecular biology resources for this genus, culminating in the completion of a draft sequence of the Populus trichocarpa (black cottonwood) genome. Numerous genetic maps are available in different Populus and Salix species and QTLs for adaptive... |

| 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... |

| Cassava suffers from bacterial blight attack in all growing regions. Control by resistance is unstable due to high genotype–environment interactions. Identifying genes for resistance to African strains of Xanthomonasaxonopodis pv. manihotis can support breeding efforts. Five F1 cassava genotypes deriving from the male parent ‘CM2177-2’ and the female parent ‘TMS30572’ were used to produce 111 individuals by backcrossing to the female parent. In all, 16 genotypes among the mapping population were resistant to stem inoculation by four strains of X. axonopodispv. manihotis from different locations in Africa, and 19 groups with differential reactions to the four strains were identified, suggesting that the strains represent different pathotypes. Four genotypes... |

| Populus nigra L. is one important species of the european alluvial forests, that are protected under Habitats directive 92/43/EEC in Europe. This species is often regarded as good indicator of geomorphological and biological quality of this ecosytem and is an active support of riparian biodiversity. This species is threatened by anthropogenic disturbances and gene introgression, justifying a french and european (EUFORGEN) programme on in situ and ex situ conservation of its genetic resources.In addition, riparian forest ecosystem and trees will face global and local climate modifications this century. Populus nigra, that establishes naturally within or along the active channel and that is strictly dependent of the morphodynamics of the river, will be... |

| La diversité génétique d’une espèce se distribue entre populations et à l’intérieur des populations. Sa prise en compte à ces deux niveaux a une importance majeure pour la mise en place de modes de gestion conservatoires in situ et ex situ. La question principale qui se pose est : quel échantillonnage de la diversité faire, enterme de populations, d’individus et de gènes ? Nous abordons ici cette question, d’un point de vue théorique à travers le éveloppement d’un modèle Monte-Carlo, puis d’un point de vue expérimental sur deux espèces forestières, le merisier et le peuplier noir, à travers une comparaison de la diversité présente en populations naturelles et en collection ex situ. Les deux approches sont ensuite mises en regard l’une de l’autre afin de... |
