The Plant DNA C‐values database (release 7.1): an updated online repository of plant genome size data for comparative studies
In recent decades, interest in plant genome size (i.e. the total amount of DNA in the unreplicated haploid nucleus; Greilhuber et al., 2005) has been growing exponentially as the biological, evolutionary and ecological significance of this key biodiversity trait is increasingly recognized (e.g. see reviews by Greilhuber & Leitch, 2013;...Pellicer, Jaume ; Leitch, Ilia J.

A Universal Probe Set for Targeted Sequencing of 353 Nuclear Genes from Any Flowering Plant Designed Using k-Medoids Clustering
Sequencing of target-enriched libraries is an efficient and cost-effective method for obtaining DNA sequence data from hundreds of nuclear loci for phylogeny reconstruction. Much of the cost of developing targeted sequencing approaches is associated with the generation of preliminary data needed for the identification of orthologous loci for probe design.... -

A roadmap for global synthesis of the plant tree of life
Providing science and society with an integrated, up‐to‐date, high quality, open, reproducible and sustainable plant tree of life would be a huge service that is now coming within reach. However, synthesizing the growing body of DNA sequence data in the public domain and disseminating the trees to a diverse audience... -

Revisiting the cytomolecular evolution of the Caesalpinia group (Leguminosae): a broad sampling reveals new correlations between cytogenetic and environmental variables
The pantropical Caesalpinia group includes 225 species in 27 monophyletic genera, and the group has undergone recent phylogenetic, taxonomic and biogeographic revisions. Previous works have reported a diverse pattern of heterochromatin distribution related to ecological niche/geographic distribution, and variation in genome size also correlated with environmental variables. In order to... -

Contrasted histories of organelle and nuclear genomes underlying physiological diversification in a grass species
C4 photosynthesis evolved multiple times independently in angiosperms, but most origins are relatively old so that the early events linked to photosynthetic diversification are blurred. The grass Alloteropsis semialata is an exception, as this species encompasses C4 and non-C4 populations. Using phylogenomics and population genomics, we infer the history of...Bianconi, Matheus E. ; Dunning, Luke T. ; Curran, Emma V. ; Hidalgo, Oriane ; Powell, Robyn F. …

Evolutionary dynamics of transposable elements and satellite DNAs in polyploid Spartina species
Repeated sequences and polyploidy play a central role in plant genome dynamics. Here, we analyze the evolutionary dynamics of repeats in tetraploid and hexaploid Spartina species that diverged during the last 10 million years within the Chloridoideae, one of the poorest investigated grass lineages. From high-throughput genome sequencing, we annotated...Giraud, Delphine ; Lima, Oscar ; Huteau, Virginie ; Coriton, Olivier ; Boutte, Julien …

Genome Size Evolution and Dynamics in Iris, with Special Focus on the Section Oncocyclus
Insights into genome size dynamics and its evolutionary impact remain limited by the lack of data for many plant groups. One of these is the genus Iris, of which only 53 out of c. 260 species have available genome sizes. In this study, we estimated the C-values for 41 species... -

How diverse is heterochromatin in the Caesalpinia group? Cytogenomic characterization of Erythrostemon hughesii Gagnon & G.P. Lewis (Leguminosae: Caesalpinioideae)
Main conclusion Cytogenomic characterization of Erythrostemon hughesii reveals a heterogeneity of repeats in its subtelomeric heterochromatin. Comparative analyses with other Caesalpinia group species reveal a significant reduction in the abundance of Ty3-gypsy/Chromovirus Tekay retrotransposons during its evolution. In numerically stable karyotypes, repetitive DNA variability is one of the main causes...Mata-Sucre, Yennifer ; Sader, Mariela ; Van-Lume, Brena ; Gagnon, Edeline ; Pedrosa-Harand, Andrea …

The Application of Flow Cytometry for Estimating Genome Size, Ploidy Level Endopolyploidy, and Reproductive Modes in Plants
Over the years, the amount of DNA in a nucleus (genome size) has been estimated using a variety of methods, but increasingly, flow cytometry (FCM) has become the method of choice. The popularity of this technique lies in the ease of sample preparation and in the large number of particles...
