Genome-Wide Characterization of Nuclear Microsatellite Markers for Centranthus trinervis (= Valeriana trinervis) and Cross-Amplification in Five Congeneric Taxa
No full textCentranthus is a small genus belonging to the family Caprifoliaceae, comprising approximately 16 taxa (nine species plus
seven subspecies). Currently, it is incorporated into the Valeriana genus, which is the most species-rich in the world (> 400
species), even though its phylogeny is not clear. Despite its botanical relevance, genetic markers for assessing the genetic
diversity and population structure of its members are scarce, thus hindering the management and conservation of wild
populations. In this study, we conducted a genome screening of the critically endangered C. trinervis to develop a set of
nuclear microsatellite markers (SSRs) for population genetic studies across this species and five congeneric species. After
data filtering, we selected 8747 contigs from which 100 primer pairs were tested in PCR. Amplification profiles returned
37 candidate microsatellites, with 13 proving informative for C. trinervis. These markers successfully cross-amplified in C.
calcitrapae (9/13), C. lecoqii (7/13), C. longiflorus (9/13), C. nevadensis (8/13), and C. ruber (8/13). The observed high level
of polymorphism and the favourable amplification rates in other congeneric species underscore the utility of these microsatellite markers as valuable tools for conservation and population genetic studies in a genus such as Centranthus or Valeriana
Can we rescue Centranthus (Caprifoliaceae: Valerianoideae) from the Valeriana sea?
Get PDFCentranthus is a small Mediterranean taxon that was recognized as a distinct genus throughout the 19th and 20th centuries, but initially and more recently was included in Valeriana. The authors propose a molecular phylogenetic study involving all the species and subspecies in Centranthus and confirming its monophyly. Two datasets were used for the phylogeny based on nuclear and plastid markers with Sanger sequencing. The first dataset (DS-I) was based on the nuclear rRNA cistron and 10 plastid markers (five genes, three introns, and two intergenic spacers) and was integrated with literature data for a wide sample of Valerianoideae; the second dataset (DS-II) involved an additional analysis exclusively focused on Centranthus taxa, incorporating five additional plastid markers (four intergenic spacers and one gene) to achieve better resolution within
this group. According to the results, the Spanish endemic V. longiflora is identified as the closest living relative of Centranthus. Despite previous hypotheses, Centranthus reliably originated in western continental Europe not in the Sardo-Corse system; in addition, two different lineages precociously originated, one including all and only the annual species, and the other including all and only the perennial ones. All our analyses suggest that the Centranthus clade is nested within a larger Valeriana with extremely strong support. Therefore, and given the relationship with V. longiflora, with the present state of knowledge, the separation of Centranthus from Valeriana appears at least to be not well justified
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
