The phylogeny of one of the putative basal-most group of land plants, the Marchantiidae, is estimated with morphological characters and with sequences of the nuclear (LSU) rDNA gene (first four domains of the 5' end of the 26S rRNA and four subsequent regions) from 34 species and 27 genera. Molecular and morphological data display high degrees of(More)
Even though their occurrence was reported a long time ago, sunken wood ecosystems at the deep-sea floor have only recently received specific attention. Accumulations of wood fragments in the deep sea create niches for a diverse fauna, but the significance of the wood itself as a food source remains to be evaluated. Pectinodonta sp. is a patellogastropod(More)
Porella platyphylla andP. cordaeana are genetically well differentiated in Europe (I = 0.486). Isozyme data from 156 European colonies reveal thatP. baueri is polyploid and could be an interspecific hybrid between these two species. It is characterized by large lobe cells, toothed margins of the female bracts, and ciliate perianth mouth. Correspondence(More)
The Hermann's tortoise (Testudo hermanni) is an endangered land tortoise distributed in disjoint populations across Mediterranean Europe. We investigated its genetic variation by typing 1 mitochondrial locus and 9 nuclear microsatellites in approximately 300 individuals from 22 localities. Our goal was to understand the relative impact of natural and(More)
Genomic libraries of Arenaria grandiflora enriched for di- and trinucleotide repeats were used for the development of novel microsatellite markers. The subset of 13 polymorphic markers was characterized on 40 individuals of A. grandiflora originating from lowland locations in France. The loci amplified 3 to 10 alleles per locus and expected heterozygosities(More)
Because they house large biodiversity collections and are also research centres with sequencing facilities, natural history museums are well placed to develop DNA barcoding best practices. The main difficulty is generally the vouchering system: it must ensure that all data produced remain attached to the corresponding specimen, from the field to publication(More)
The primary purpose ofDNA-barcoding projects is to generate an efficient expertise and identification tool. This is an important challenge to the taxonomy of the 21st century, as the demand increases and the expert capacity does not. However, identifying specimens usingDNA-barcodes requires a preliminary analysis to relatemolecular clusters to available(More)
This article documents the addition of 396 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Anthocidaris crassispina, Aphis glycines, Argyrosomus regius, Astrocaryum sciophilum, Dasypus novemcinctus, Delomys sublineatus, Dermatemys mawii, Fundulus heteroclitus, Homalaspis plana, Jumellea(More)
UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for the understudied root crop yam bean (Pachyrhizus spp.) to investigate intraspecific diversity and interspecific relationships within the genus Pachyrhizus. • METHODS AND RESULTS Seventeen nuclear simple sequence repeat (SSR) markers with perfect di- and trinucleotide repeats were(More)
The rise and diversification of land plants was accompanied by mycorrhizal symbiosis, from their emergence to their adaptation to various biomes and ecological situations (Selosse et al., 2015). In most mycorrhizal associations, fungi provide soil minerals to the plant, in exchange for sugars derived fromphotosynthesis (Smith& Read, 2008; van der Heijden et(More)
