Morphological and genomic characterization of Rhynchospora tenuis complex (Cyperaceae) and its taxonomic implications [PDF]
Rodriguesia, 2012 Species of Rhynchospora sect. Tenues are morphologically very similar. Rhynchospora tenuis complex is the most problematic species complex in this group and it concentrates entities of difficult delimitation, as is the case of R. tenuis, R. tenuis subsp. austro-brasiliensis and R. enmanuelis.

Genetics and Molecular Biology, 2003 Rhynchospora tenuis Link (Cyperaceae) is a weed widely distributed in Brazil that presents a small number of holocentric chromosomes (2n = 4) with some autopolyploid populations (2n = 8). The haploid number n = 2 is considered as a derivative of the base number x = 5.

Scrub encroachment promotes biodiversity in temperate European wetlands under eutrophic conditions [PDF]
Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022 We examine the effects of encroachment on biodiversity along gradients of soil moisture and soil fertility in open and wooded wetlands in Denmark. Our results support existing knowledge of the importance of nutrient poor, wet mires and meadows for rare species but on former arable lands where restoration of infertile habitats is less feasible we ...

The genome of Eleocharis vivipara elucidates the genetics of C3–C4 photosynthetic plasticity and karyotype evolution in the Cyperaceae [PDF]
Journal of Integrative Plant Biology, Volume 66, Issue 11, Page 2505-2527, November 2024.Eleocharis vivipara provides a prime model for studying photosynthetic plasticity, as it uses C3 photosynthesis underwater and C4 photosynthesis on land. The assembled genome and dynamic gene expression patterns provide new insights into the genetic basis of this photosynthetic transition, which can contribute to crop improvement and breeding ...

Centromere diversity and its evolutionary impacts on plant karyotypes and plant reproduction [PDF]
New Phytologist, Volume 245, Issue 5, Page 1879-1886, March 2025.Summary Karyotype changes are a formidable evolutionary force by directly impacting cross‐incompatibility, gene dosage, genetic linkage, chromosome segregation, and meiotic recombination landscape. These changes often arise spontaneously and are commonly detected within plant lineages, even between closely related accessions.

Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii [PDF]
Advanced Science, Volume 12, Issue 32, August 28, 2025.The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.

Condensation patterns of prophase/prometaphase chromosome are correlated with H4K5 histone acetylation and genomic DNA contents in plants. [PDF]
PLoS ONE, 2017 Mitotic prophase chromosome condensation plays an essential role in nuclear division being therefore regulated by highly conserved mechanisms. However, degrees of chromatin condensation in prophase-prometaphase cells may vary along the chromosomes ...

Developing and Validating Species Distribution Models for Wetland Plants Across Europe [PDF]
Ecology and Evolution, Volume 15, Issue 4, April 2025.We fitted species distribution models (SDMs) for 265 wetland plant species in Europe. We validated predicted occurrences using independent data. The SDMs showed a high predictive performance, such that our SDMs can be used to predict broad‐scale distributions of wetland plants.
