The genus Ludwigia L. section Jussiaea is composed of a polyploid species complex with 2x, 4x, 6x and 10x ploidy levels, suggesting possible hybrid origins. aim the present study to understand genomic relationships among diploid in Jussiaea. Morphological cytogenetic observations, controlled crosses, situ hybridization (GISH), flow cytometry were used characterize species, patterns, composition across taxa. Genome sizes obtained agreement diploid, tetraploid, hexaploid, decaploid levels....
Ongoing global changes affect ecosystems and open up new opportunities for biological invasion. The ability of invasive species to rapidly adapt environments represents a relevant model studying short-term adaptation mechanisms. aquatic plant, Ludwigia grandiflora subsp. hexapetala, is classified as harmful in European rivers. In French wet meadows, this has shown rapid transition from terrestrial with emergence two distinct morphotypes 5 years. To understand the heritable mechanisms...
Fruit-set and seed-set depend on environmental conditions reproductive systems. They are important components of sexual success in plants. also control the ecological adaptation invasive plants within their non-native ecosystems. We studied which factors bring about fruit-set populations aquatic plant Ludwigia grandiflora subsp. hexapetala. analyzed fruit set seed 37 growing under variable climatic Western Europe. Sub-samples seven fruitful fruitless were grown common controlled conditions....
Breeding system influences local population genetic structure, effective size, offspring fitness and functional variation. Determining the respective importance of self- cross-fertilization in hermaphroditic flowering plants is thus important to understand their ecology evolution. The worldwide invasive species, Ludwigia grandiflora subsp. hexapetala (Lgh) presents two floral morphs: one self-compatible short-styled morph (S-morph) self-incompatible long-styled (L-morph). In this study, we...
Abstract Reproductive mode, i.e., the proportion of individuals produced by clonality, selfing and outcrossing in populations, determines how hereditary material is transmitted through generations. It shapes genetic diversity its structure over time space, which can be used to infer reproductive modes. Ludwigia grandiflora subsp. hexapetala ( Lgh ) a partially clonal, polyploid, hermaphroditic, heteromorphic plant that recently colonized multiple countries worldwide. In western Europe, are...

We selected polypore mushrooms growing in the Mediterranean area of France to screen their antioxidant activity: Ganoderma applanatum, G. lucidum, Inonotus cuticularis, I. hispidus, Trametes hirsuta, and T. versicolor. Our work also evaluated capacity from wild cultivated lucidum fruiting bodies optimize this biological property on human health. Dried fungal materials were sequentially extracted using cyclohexane, dichloromethane, ethanol, water. Folin-Ciocalteu assay, oxygen radical...
Abstract Successful plant colonization by parasites requires the circumvention of host defenses, and sometimes a reprogramming metabolism, mediated effector molecules delivered into host. Using transcriptomic enzymatic approaches, we characterized salivary glands saliva Phloeomyzus passerinii , an aphid exhibiting atypical feeding strategy. Plant genes responses to extracts P. Myzus persicae were assessed with poplar protoplasts susceptible resistant genotype, in heterologous Arabidopsis...

Summary Fruitfulness and fertility are important components of sexual reproductive success in plants, often depends on environmental conditions systems. For invasive fruitfulness control their ecological adaptation invaded ecosystems. We studied which factors bring about populations the aquatic plant Ludwigia grandiflora subsp. hexapetala . analysed 37 growing under variable climatic Western Europe, sub-sampled fruitful fruitless grown common controlled conditions. carried out self-...
