Full textZooplankton community of solar saltern of Sfax. A dozen of species were identified in four ponds of increasing salinity. Copepods were the most abundant group in A5, A16 and C41. M2 is monozoic with an exclusive presence of Artemia salina. Salinity have a crucial role in species distribution, whereas, other factors such as N:P ratio have smaller influence. Fatty acids composition of copepods and Artemia depends on physico-chemical and biological parameters. Owing to their Highly unsaturated fatty acids (HUFAs) composition, copepods and Artemia of the saltern of Sfax can be used as food source for cultured fishes. Copepods phylogeny is controversial because their genetic structure is not clearly identifiable. The existence of cryptic species within Paracartia grani is assumed but should be confirmed. Abiotic factors are not involved in processes of genetic divergence. For Artemia salina, the high salinity, is a factor of population segregation, the adaptation of Artemia in such condition leads to distinct, genetically, population. A genetic divide was identified, it highlights a separation between population living in high salinity and those in the sea

Full textThe importance of these unusual structures for fatty acids, the development of genetic engineering and the identification and isolation of many genes involved in the biosynthesis and regulation of lipid metabolism in plants, have provided new perspectives for the production of vegetable oil with a higher value in field crops. In this perspective, REFLAX and PAGIOS programmes were developed. The aim of these projects is the production of unusual fatty acids in agronomie plants (rapeseed and flan), through the creation of a new ,biosthetic pathway for branched fatty acids in the plast. Rapeseed plants were transformed with four bacterial enzymes: TD, KS, PCCA and PCCB. These proteins were identified as key enzymes in the synthesis of branched fatty acids. The level of methylmalonyl-CoA, a precursor of the methyl branched fatty acid synthesis, was amplified thanks to the introduction of these four genes. However the accumulation of methyl branched-chain fatty acids in rapeseed plants transformed, remains very low (<2%). To get a deeper understanding of this low production of BFA, we incubated whole rapeseed embryos, at different stages of development, in presence of 13C-labelled glucose and observed the label redistribution by NMR. The NMR and biochemical analysis showed that the synthesis of BFA was very low and transient (only at 15 J). Biomass synthesis fluxes were similar between native and transformed plant. The central carbon metabolism was not affected by the introduction of these genes. However, an accumulation of' pyruvate and kétobutyrate and a low accumulation of branched Chain amino acids (leucine, isoleucine and valine) at the transformed lines were observed

Full textThis study is mostly dedicated to microorganisms-crustacean zooplankton trophic relationships occurring in Lake Annecy. Nutrition experiments were performed to evaluate food quality of heterotrophic protists for zooplankton. Food contents in (n-3) Polyunsaturated Fatty Acids (PUFA) seem to be the main factor determining food quality. Moreover this study shows that the addition of an algivorous flagellate as an intermediary trophic level in the microalga-zooplancton food chain enhance Daphnia hyalina development. Trophic upgrading of food quality may be surely associated to biosynthetic capacities of heterotrophic protists. The field study mainly focused on FA transfer between microbial communities and crustacean zooplankton sampled in the pelagic zone between march and september 2000. To facilitate the FA biomarker approach, seston has been fractionated in different size classes. The evolution of 20:5(n-3) contents in Daphnia hyalina lipids has been positively correlated to its fecundity. Cryptophytes and centric diatoms appears as the main sources in (n-3) PUFA for the cladoceran. Endly the reliability of fatty acids-specific stable isotope analysis (ς13C) for trophic studies has been assessed

Full textOmega-hydroxylated fatty acids play diversified roles in the plant : they constitute monomers of the plant polyesters cutin and suberin, second messengers in plant-pathogen interactions, and are intermediates of the fatty acids catabolism. Cytochrome P450 isoforms from CYP86 and CYP94 families could be implicated in these reactions. The identification of some of these isoforms is the aim of our work. In Vicia sativa, high concentrations (50 to 500 µM) of chemicals (clofibrate, 2,4-D, 2,3-D, IAA, SA, methyljasmonate) applied on the seedlings produce a strong induction of CYP94A1. A promotor analysis revealed the occurrence of an as-1 regulatory sequence, which, as in the regulation of isoform 6 of the glutathione-S-transferase, would suggest a role in the detoxification of free fatty acids. CYP86B1 and CYP86B2 from Arabidopsis thaliana are involved in the biosynthesis of suberin monomers in the root endodermis, and probably in the production of lipids for the pollen coat and the wall of pollen grains
