A new species of Semisulcospira O. Boettger, 1886 (Gastropoda, Cerithoidea, Semisulcospiridae) from Fujian, China with mitochondrial genome and its phylogenetic implications [PDF]

Zoosystematics and Evolution
During our investigation of the diversity and phylogeny of the family Semisulcospiridae in China, we have found a presumed new species in mountain streams of Xiamen, Fujian Province on both morphology and molecular evidence.

Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

Characterization and Identification of Pulsatilla koreana and Pulsatilla tongkangensis Seedlings Based on Morphology, Colorimetric Data, and Molecular Markers

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Pulsatilla tongkangensis, an endemic species growing in the limited areas in Korea, is considered endangered species, and is growing in sympatric with P. koreana enabling natural hybridization. To characterize the true to the type of P. tongkangensis, we integrated morphological traits and molecular analyses of the nuclear ribosomal ITS (nrITS) and the

Involvement of the specific nucleolar protein SURF6 in regulation of proliferation and ribosome biogenesis in mouse NIH/3T3 fibroblasts [PDF]

, 2017
The nucleolar proteins which link cell proliferation to ribosome biogenesis are regarded to be potentially oncogenic. Here, in order to examine the involvement of an evolutionary conserved nucleolar protein SURF6/Rrp14 in proliferation and ribosome ...

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).

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

Zoologica Scripta, Volume 55, Issue 2, Page 368-387, March 2026.
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 ...
