| The objective of this work was to evaluate the genetic diversity, its organization and the genetic relationships within oil palm (Elaeis oleifera (Kunth) Cortés, from America, and E. guineensis (Jacq.), from Africa) germplasm using Restriction Fragment Length Polymorphism (RFLP) and Amplified Fragment Length Polymorphism (AFLP). In complement to a previous RFLP study on 241 E. oleifera accessions, 38 E. guineensis accessions were analyzed using the same 37 cDNA probes. These accessions covered a large part of the geographical distribution areas of these species in America and Africa. In addition, AFLP analysis was performed on a sub-set of 40 accessions of E. oleifera and 22 of E. guineensis using three pairs of enzyme/primer combinations. Data were... |

| Genetic diversity in the genus Elaeis was evaluated by the restriction fragment length polymorphism (RFLP) and amplified fragment length polymorphism (AFLPtm) techniques, on a set of accessions from E. oleifera (241 accessions), E. guineensis (39), and Barcella odora (three accessions), representing the geographical areas of distribution for the genus. RFLPs were detected by hybridizing 13 nuclear and four mitochondrial probes onto blots of total DNA extracted from individuals and digested by one of the following restriction enzymes: EcoRI, Bg/II, SstI, or EcoRV. AFLP was performed on a subset of the same individuals using only one primer combination. Factorial analysis of correspondences and cluster analysis of one primer combination. Factorial analysis... |

| We chose an Elaeis interspecific pseudo-backcross of first generation (E. oleifera × E. guineensis) × E. guineensis to identify quantitative trait loci (QTLs) for fatty acid composition of palm oil. A dense microsatellite linkage map of 362 loci spanned 1.485 cM, representing the 16 pairs of homologous chromosomes in the Elaeis genus from which we traced segregating alleles from both E. oleifera and E. guineensis grandparents. |

| Degraded soil areas in vineyards are associated with problems in vine health, grape production and quality. Different causes for soil degradation are possible such as poor organic matter content, lower plant nutrient availability, pH, water deficiency, soil compaction / lower oxygenation… The aim of this preliminary study is to assess soil functionality (OM decomposition), biodiversity through mesofauna diversity and consequences for vine growth and quality. |

| The genetic diversity of E. oleifera is strongly structured by geographical origin, with four groups clearly distinguished: Brazil, Surinam/French Guyana, north of /Colombia/Central America and Peru. Within the Amazon basin, thereis a moderate structure that corresponds to the major tributaries of the Amazon river. From the 37 polymorphic RFLP probe/enzyme combinatios used, 19 probes (51%) presented simple restriction profiles, with one (1) or two bands/plant, suggesting a single locus with different alleles, allowing allelic co-dominant coding for them. |
