The origin of Cucumis melo, related wild species and domestication events that have led to the current variability of Picó Sirvent, MB are described. (2015). The origin of the melon: genetic diversity of the species. http://hdl.handle.net/10251/52031

Iron metabolism disorders, including iron overloads, are characterized by important phenotypic expression variabilities for similar etiologies. The mechanisms involved are not fully identified. Interrelations between iron and other metals may contribute to this variability. The aim of this work, per...

Intravenous exposure to endotoxins can cause acute respiratory distress syndrome due to the strong inflammatory reactions they initiate. Paradoxically, it has also been shown that exposure to endotoxins can have a beneficial role in allergic type diseases with genetic predisposition (atopia), especi...

Species distributions have been profoundly affected by past climate change, and are expected to change considerably in response to future environmental change. To better apprehend how future climate change is likely to affect genetic diversity in marine populations, it is essential to first evaluate...

Cassava is considered a food security crop because yields fluctuate less during periods of environmental perturbation than cereal crops. Besides, it feeds almost a billion people daily. The plant is highly dependent on Arbuscular Mycorrhizal Fungi (AMF) for its growth and nutrient acquisition. AMF a...

Consumption of omega-3 (n-3) polyunsaturated fatty acids of marine origin reduces plasma triglyceride (TG) levels and increases cholesterol (C) concentrations of low density lipoproteins (LDL) as well as LDL particle size. There is a significant inter-individual variability in the supplementation re...

International audience The distribution of genetic variation and the phylogenetic relationships between 18 populations of the arctic-alpine plant Trollius europaeus were analysed in three main regions (Alps, Pyrenees and Fennoscandia) by using dominant AFLP markers. Analysis of molecular variance re...

Due to their high mobility, large terrestrial predators are potentially capable of maintaining high connectivity, and therefore low genetic differentiation among populations. However, previous molecular studies have provided contradictory findings in relation to this. To elucidate patterns of geneti...

The cucumber (Cucumis sativus L.) is an important crop worldwide. In the present study, the molecular genetic diversity of 131 Spanish accessions was analyzed using 23 simple sequence repeat (SSRs). Eighteen of these SSRs were polymorphic; the mean number of alleles, mean observed heterozygosity and...

International audience American trypanosomiasis or Chagas disease is endemic in Latin America and caused by the flagellate Trypanosoma cruzi, which exhibits broad genetic variation. In various areas, the transmission of Chagas disease is ensured by sylvatic vectors, mainly carrying the evolutionary...

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is considered one of the most economically damaging pests of citrus orchards in Spain. The characterization of C. capitata population structure, at a large geographical scale, by using a combination of RAPD and ISSR...

The fast rotation of new cultivars demanded by modern fruit growers implies the loss of many old varieties with valuable characters. Then, the need arises to keep and characterize this germplasm for future breeding projects. The region of Murcia, together with Valencia, in the East and Southeast of...

International audience Proteomics allows studying large numbers of proteins, including their post-translational modifications. Proteomics has been, and still are, used in numerous studies on skeletal muscle. In this article, we focus on its use in the study of livestock muscle development and meat q...

In Mediterranean regions, water scarcity associated with climate change particularly threatens the sustainability of viticulture. Breeding grapevine for reduced water use and maintained production is therefore of major interest. This requires a comprehensive knowledge of the plant physiological resp...

International audience The last two decades have seen numerous debates in the field of the initial settlement of America and noteworthy was the disagreement between physical and molecular anthropologists. Recently, it has been pointed out that this discordance could partly originate from the descrip...

Cyclosporine A (CsA) presents a wide interindividual variability in its kinetics. CsA is a substrate of P-glycoprotein (PGP), an efflux transporter which is the product of the MDR1 gene and present on intestinal cells, among others. Contradictory reports were published on the influence of MDR1 polym...

ABSTRACT The role of chromosomal rearrangements in the speciation process is much debated and many theoretical models have been developed. The shrews of the Sorex araneus group offer extraordinary opportunities to study the relationship between chromosomal variation and speciation. Indeed, this grou...

Polianthes tuberosa L. is an endemic plant in Mexico, commercially grown for cutting flowers, and is also used in the pharmaceutical and perfume industry. Traditionally, producers spread it using the corms, which has meant that the crop has little genetic variability and, for this reason, only whit...

Societal Impact Statement Crop wild relatives (CWR) are plant taxa closely related to crops and are a source of high genetic diversity that can help adapt crops to the impacts of global change, particularly to meet increasing consumer demand in the face of the climate crisis. CWR provide vital ecosy...

The study of the inherited features of the genotype and the directions of variability of breeding-valuable traits of strawberry varieties and hybrid forms is an integral part of most researches in the field of this crop breeding. The purpose of this work was to determine the most promising strawberr...

Comprehensive inspection of millet original forms and their involvement in the breeding process to create new varieties and lines is an urgent problem and is of great theoretical and practical importance [3,4]. New varieties should be resistant to abiotic stresses and ecological plasticity, as globa...
