In this study, we identified and characterized 160 microsatellite loci from an expressed sequence tag (EST) database generated from immune-related organs of turbot (Scophthalmus maximus). A final set of 83 new polymorphic microsatellites were validated after the analysis of 40 individuals of Atlantic origin including both wild and farmed individuals. The allele number and the expected heterozy...<br/><br/>Rafael Navajas-Pérez, Robles F, Molina-Luzón MJ, de la Herrán, R, Álvarez-Dios JA, Pardo BG, Vera M, Bouza C, Martínez P (2012) <i>Molecular Ecology Resources</i> in press: <br/>

One of the most important topics in evolutionary biology concerns the origin and evolution of sex-determining systems and sex chromosomes. Certain plant species display younger sex-chromosome systems in different evolutionary stages. It is thought that the same evolutionary forces described for animals are operating in plants. However, in opposition to the situation in animals, sex-determining mec...<br/><br/>Pedro J.

We studied the evolution of RAE180 satellite DNA family in the North American endemic dioecious plant Rumex hastatulus. In this species, the Texas race is characterized by a single XX/XY sex chromosome system, whereas the North Carolina race has evolved a derived complex XX/XY1Y2 sex chromosome system. RAE180 repeats were autosomic and poorly represented (2 × 10–4% of the genome) with no dif...<br/><br/>M. Ester Quesada del Bosque, Rafael Navajas-Pérez, José L.

Senegal sole (Solea senegalensis L.) is a flatfish (Order Pleuronectiformes) that in recent years has aroused great interest in the aquaculture mainly in southern Spain and Portugal, constituting a viable alternative to the traditional culture of sea bass and sea bream. In fact, the culture of this fish is gradually increasing due to its relatively rapid growth and a high price in the market.
