Using the Multiple Analysis Approach to Reconstruct Phylogenetic Relationships among Planktonic Foraminifera from Highly Divergent and Length-polymorphic SSU rDNA Sequences

open access: yesBioinformatics and Biology Insights, 2009
The high sequence divergence within the small subunit ribosomal RNA gene (SSU rDNA) of foraminifera makes it difficult to establish the homology of individual nucleotides across taxa.

Phylogenetic Analysis of Nuclear-Encoded RNA Maturases

open access: yesEvolutionary Bioinformatics, 2017
Posttranscriptional processes, such as splicing, play a crucial role in gene expression and are prevalent not only in nuclear genes but also in plant mitochondria where splicing of group II introns is catalyzed by a class of proteins termed maturases ...

Third-codon transversion rate-based _Nymphaea_ basal angiosperm phylogeny -- concordance with developmental evidence [PDF]

open access: yes, 2007
Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years.

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

The complete mitochondrial genome of Mactra quadrangularis (Mactridae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
The whole mitochondrial genome sequence of Mactra quadrangularis (Reeve, 1854) was determined. It had a total length of 16,848 bp and it contained 12 protein coding genes, 2 ribosome RNA genes, and 22 transfer RNA genes. The base composition was 25.75% A,

Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

open access: yesFEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Sequence and Phylogenetic Analysis of Influenza Virus (H1N1pdm2009) Circulating in Riyadh, Saudi Arabia

open access: yesJournal of Pure and Applied Microbiology
Influenza A virus (IAV) is the principal cause of seasonal flu and is often reported among pilgrims in Saudi Arabia (SA) due to their mass gatherings.

The complete mitochondrial genome of Batocera rubus Linnaeus, 1785 (Coleoptera: Cerambycidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
Batocera rubus severely impacts on the health of banyan trees. In this study, the whole mitochondrial genome for B. rubus was found to be 16,158 bp with a GC content of 23.9%, including 39.1% A, 37.0% T, 14.8% C, and 9.1% G.

A new species in the major malaria vector complex sheds light on reticulated species evolution [PDF]

open access: yes, 2019
Complexes of closely related species provide key insights into the rapid and independent evolution of adaptive traits. Here, we described and studied Anopheles fontenillei sp.n., a new species in the Anopheles gambiae complex that we recently discovered ...

Stability analysis of phylogenetic trees [PDF]

open access: yesBioinformatics, 2012
Abstract Motivation: Phylogenetics, or reconstructing the evolutionary relationships of organisms, is critical for understanding evolution. A large number of heuristic algorithms for phylogenetics have been developed, some of which enable estimates of trees with tens of thousands of taxa. Such trees may not be robust, as small changes in
