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... -

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.

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... -

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... -

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 …

Selecting for useful properties of plants and fungi – Novel approaches, opportunities, and challenges
Societal Impact Statement For millennia, humans have used plants and fungi, as foods, fuels, fibers, and medicines; and have developed techniques for improving their usefulness to our species, mostly through selection of desirable traits. With human populations forecast to rise, the availability of arable land likely to fall amid climate...
