Morphology, Ontogenesis, and Multi‐Gene Phylogeny of the Type Species Cyrtohymena muscorum (Kahl, 1932) Foissner, 1989 (Alveolata, Ciliophora, Hypotricha)

Zoologica Scripta, EarlyView.
ABSTRACT Members of the oxytrichid genus Cyrtohymena are characterised by a distinctive undulating membranes type, known as the Cyrtohymena pattern, featuring a strongly curved stichodyad paroral that forms a semicircle distally. Although the type species, Cyrtohymena muscorum, has been redescribed morphologically, its ontogenesis remains poorly ...

Nuclear, mitochondrial and plastid gene phylogenies of Dinophysis miles (Dinophyceae): evidence of variable types of chloroplasts.

PLoS ONE, 2011
The Dinophysis genus is an ecologically and evolutionarily important group of marine dinoflagellates, yet their molecular phylogenetic positions and ecological characteristics such as trophic modes remain poorly understood.

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

BMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Macroid Formation in Salmacina stellaebayensis n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida)

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Conserved Organisation of 45S rDNA Sites and rDNA Gene Copy Number among Major Clades of Early Land Plants. [PDF]

PLoS ONE, 2016
Genes encoding ribosomal RNA (rDNA) are universal key constituents of eukaryotic genomes, and the nuclear genome harbours hundreds to several thousand copies of each species.

Versatile and Selective Biomolecule Pulldown with Combinatorial DNA‐Crosslinked Polymers

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
We present a programmable smart polymer system for universal, sequence‐selective bioseparation under native conditions. Polymer phase separation is achieved through combinatorial DNA crosslinking, enabling the capture of DNA, RNA, or proteins in a homogeneous solution with high pulldown efficiency and near‐zero background binding.
