A new species of Petraeomastus Möllendorff, 1901, with an atypical shell morphology from the Lancangjiang River Valley in southwest China (Gastropoda, Stylommatophora, Enidae) [PDF]

Zoosystematics and Evolution
Our study contains the first molecular phylogeny of Chinese enids based on the mitochondrial markers cytochrome oxidase c (COI) and 16S rRNA (16S). We have sequenced 19 species belonging to 10 out of the 12 currently accepted genera.

Patellariopsidaceae Fam. Nov. With Sexual-Asexual Connection and a New Host Record for Cheirospora botryospora (Vibrisseaceae, Ascomycota)

Frontiers in Microbiology, 2020
Helotiales is a polyphyletic order of Ascomycetes. The paucity of relevant molecular data and unclear connections of sexual and asexual morphs present challenges in resolving taxa within this order. In the present study, Patellariopsidaceae fam.

A molecular phylogeny and classification of Verbenaceae [PDF]

American Journal of Botany, 2010
• Premise of the study: Verbenaceae consist of trees, shrubs, lianas, and herbs distributed primarily in Latin America, where they occur in a wide array of ecosystems. A second center of diversity exists in Africa. Competing morphology‐based classifications that rely on different traits conflict in significant ways.

2011 German Escherichia coli outbreak: Alignment-free whole-genome phylogeny by feature frequency profiles [PDF]

, 2011
Accuracy of SNP-based whole-genome phylogeny reconstruction relies heavily on quality of sequence alignment which is particularly hindered by poorly assembled genomes. Alignment-free methods might provide additional insights. Here, we constructed a whole-

Computational Reproducibility of Molecular Phylogenies

Molecular Biology and Evolution, 2023
Abstract Repeated runs of the same program can generate different molecular phylogenies from identical data sets under the same analytical conditions. This lack of reproducibility of inferred phylogenies casts a long shadow on downstream research employing these phylogenies in areas such as comparative genomics, systematics, and ...

Apical groove type and molecular phylogeny suggests reclassification of Cochlodinium geminatum as Polykrikos geminatum. [PDF]

PLoS ONE, 2013
Traditionally Cocholodinium and Gymnodinium sensu lato clade are distinguished based on the cingulum turn number, which has been increasingly recognized to be inadequate for Gymnodiniales genus classification. This has been improved by the combination of

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]

, 2012
Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Molecular phylogeny of the genus Lythria and description of the male genitalia of L. venustata (Lepidoptera: Geometridae: Sterrhinae)

European Journal of Entomology, 2009
We present a molecular phylogeny incorporating all five species of the Palaearctic geometrid genus Lythria, based on a 2810-bp combined data matrix comprising the full sequence of the mitochondrial gene cytochrome oxidase subunit one (COI) and fragments ...
