PHYLOGENETIC SIGNATURES IN THE JUVENILE SKULLS AND CHEEK TEETH OF PLEISTOCENE PROBOSCIDIPPARION SINENSE, CHINA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2015
We describe and compare three partial skulls of Chinese juvenile Proboscidipparion sinense from the Nihewanian of China. Study of the facial morphology, especially the nasal aperture, as well as cheek tooth morphology and metric data, including length ...

On the evolutionary relationship between chondrocytes and osteoblasts [PDF]

open access: yesFrontiers in Genetics, 2015
Vertebrates are the only animals that produce bone, but the molecular genetic basis for this evolutionary novelty remains obscure. Here, we synthesize information from traditional evolutionary and modern molecular genetic studies in order to generate a working hypothesis on the evolution of the gene regulatory network (GRN) underlying bone formation ...

The complete mitochondrial genome sequence and gene organization of Lepidotrigla Kanagashira (Scorpaeniformes, Triglidae) with phylogenetic consideration

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete mitochondrial genome DNA sequence of Lepidotrigla kanagashira was 16,504 bp in length. It consists of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and one control region.

Evolutionary Relationships among Bacterial Carbamoyltransferases [PDF]

open access: yesMicrobiology, 1989
An immunological approach was used for the study of ornithine carbamoyltransferase (OTCase) evolution in bacteria. Antisera were prepared against the anabolic and catabolic OTCases of Pseudomonas aeruginosa and Aeromonas formicans as well as against OTCase and putrescine carbamoyltransferases from Streptococcus faecalis; these antisera were then tested

The complete mitochondrial genome of Gephyrocharax atracaudatus (Characiformes, Characidae) and phylogenetic studies of Characiformes

open access: yesMitochondrial DNA. Part B. Resources, 2019
Here, we report the complete mitochondrial genome sequence of Gephyrocharax atracaudatus. The genome is found to be 17,049 bp in length and has a base composition of A (29.95%), G (15.29%), C (26.13%) and T (28.63%).

Complete mitochondrial genome analysis of Japanese Spanish mackerel (Scomberomorus niphonius) with phylogenetic consideration

open access: yesMitochondrial DNA. Part B. Resources, 2017
The complete mitochondrial DNA (mtDNA) of Japanese Spanish mackerel (Scomberomorus niphonius) was cloned and sequenced. The total length of the mitochondrial genome is 16,646 bp with an accession number KY228987.

Evolutionary relationships between Archaea and eukaryotes

open access: yesNature Ecology & Evolution, 2019
A phylogenomic re-analysis of sequence data strongly supports the emergence of eukaryotes from within the archaeal radiation and underlines the importance of using the most accurate approaches to reconstruct ancient divergences in the tree of life.

A phylogenomic framework of Gastrotricha evolutionary relationships

open access: yesMolecular Phylogenetics and Evolution
Gastrotricha are microscopic acoelomate worms that play key ecological roles in marine and freshwater meiobenthic communities. For a long time, their relationships have been inferred primarily from morphology, or from molecular studies based on only a few genes, due to the scarcity of genomic resources. Here we analyzed 221 nuclear loci from 31 species

Genome-wide identification and functional characterization of the KWL gene family in three Oryza species

open access: yesFrontiers in Plant Science
IntroductionThe Kiwellin (KWL) gene family, although previously implicated in plant stress responses, remains poorly characterized in rice. This study aims to perform a comprehensive genome-wide analysis of the KWL family across three rice species to ...
