PREMISE OF THE STUDY Microsatellite primers were developed in the perennial herbs of the diploid-polyploid complex Veronica subsect. Pentasepalae (Plantaginaceae) to investigate the role that hybridization has played in the evolution of the group, which includes several endangered species. METHODS AND RESULTS Twelve pairs of primers leading to polymorphic(More)
PREMISE OF THE STUDY Microsatellite primers were developed for the first time in the root hemiparasite herb Odontites vernus (Orobanchaceae). These markers will be useful to investigate the role of polyploidization in the evolution of this diploid-tetraploid complex, as well as the extent of gene flow between different ploidy levels. METHODS AND RESULTS(More)
Astragalus edulis (Fabaceae) is an endangered annual species from the western Mediterranean region that colonized the SE Iberian Peninsula, NE and SW Morocco, and the easternmost Macaronesian islands (Lanzarote and Fuerteventura). Although in Spain some conservation measures have been adopted, it is still necessary to develop an appropriate management plan(More)
The variation and evolutionary dynamics of the twin hairs covering the achenes of the external female florets in Filago and related genera are studied using scanning electron microscope (SEM) and a Bayesian reconstruction of ancestral character states. A molecular phylogenetic hypothesis based on sequences of ITS and ETS (nuclear ribosomal DNA) and plastid(More)
Recent studies have proposed a monophyletic circumscription of Filago and a new subgeneric treatment for this genus. The aim of this study was to analyse the nuclear genome size in a phylogenetic framework in order to evaluate the systematic significance of this trait to provide insights into the dynamics of genome size evolution and to assess relationships(More)
