Morphological and genomic characterization of Rhynchospora tenuis complex (Cyperaceae) and its taxonomic implications [PDF]

Rodriguésia, 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.

Localization of 45S rDNA and telomeric sites on holocentric chromosomes of Rhynchospora tenuis Link (Cyperaceae)

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

Scrub encroachment promotes biodiversity in temperate European wetlands under eutrophic conditions. [PDF]

Ecol Evol, 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 ...

Centromere diversity and its evolutionary impacts on plant karyotypes and plant reproduction. [PDF]

New Phytol
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.

The genome of Eleocharis vivipara elucidates the genetics of C₃-C₄ photosynthetic plasticity and karyotype evolution in the Cyperaceae. [PDF]

J Integr Plant Biol
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 ...

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 ...

Genomic and Cis-Regulatory Basis of a Plastic C₃-C₄ Photosynthesis in Eleocharis Baldwinii. [PDF]

Adv Sci (Weinh)
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.

Developing and Validating Species Distribution Models for Wetland Plants Across Europe. [PDF]

Ecol Evol
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.
