Evidence for 5S rDNA Horizontal Transfer in the toadfish Halobatrachus didactylus (Schneider, 1801) based on the analysis of three multigene families [PDF]

open access: yes, 2012
Background The Batrachoididae family is a group of marine teleosts that includes several species with more complicated physiological characteristics, such as their excretory, reproductive, cardiovascular and respiratory systems.

Long-term evolution of 5S ribosomal DNA seems to be driven by birth-and-death processes and selection in "Ensis" razor shells (Mollusca: Bivalvia) [PDF]

open access: yes, 2009
[Abstract] A study of nucleotide sequence variation of 5S ribosomal DNA from six Ensis species revealed that several 5S ribosomal DNA variants, based on differences in their nontranscribed spacers (NTS), occur in Ensis genomes.

Molecular evolutionary and structural analysis of familial exudative vitreoretinopathy associated FZD4 gene

open access: yesBMC Evolutionary Biology, 2019
Background Frizzled family members belong to G-protein coupled receptors and encode proteins accountable for cell signal transduction, cell proliferation and cell death. Members of Frizzled receptor family are considered to have critical roles in causing

Differential in vitro and in vivo effect of barley cysteine and serine protease inhibitors on phytopathogenic microorganisms [PDF]

open access: yes, 2011
Protease inhibitors from plants have been involved in defence mechanisms against pests and pathogens. Phytocystatins and trypsin/α-amylase inhibitors are two of the best characterized protease inhibitor families in plants.

Two new species of Pholiota (Agaricales, Strophariaceae) from the southwest of China [PDF]

open access: yesMycoKeys
Two new mushroom species from Southwest China, Pholiota cylindrospora and P. subterrestris, are described in this study. Pholiota cylindrospora is characterized by its dry pileus with slightly recurved and triangular scales, cylindrical basidiospores ...

Evolution-guided functional analyses reveal diverse antiviral specificities encoded by IFIT1 genes in mammals. [PDF]

open access: yes, 2016
IFIT (interferon-induced with tetratricopeptide repeats) proteins are critical mediators of mammalian innate antiviral immunity. Mouse IFIT1 selectively inhibits viruses that lack 2'O-methylation of their mRNA 5' caps.

Exploration of phylogenetic data using a global sequence analysis method

open access: yesBMC Evolutionary Biology, 2005
Background Molecular phylogenetic methods are based on alignments of nucleic or peptidic sequences. The tremendous increase in molecular data permits phylogenetic analyses of very long sequences and of many species, but also requires methods to help ...

Evolutionary history of the human multigene families reveals widespread gene duplications throughout the history of animals

open access: yesBMC Evolutionary Biology, 2019
Background The hypothesis that vertebrates have experienced two ancient, whole genome duplications (WGDs) is of central interest to evolutionary biology and has been implicated in evolution of developmental complexity.

Progressive and biased divergent evolution underpins the origin and diversification of peridinin dinoflagellate plastids [PDF]

open access: yes, 2016
Dinoflagellates are algae of tremendous importance to ecosystems and to public health. The cell biology and genome organization of dinoflagellate species is highly unusual.

Annabella australiensis gen. & sp. nov. (Helotiales, Cordieritidaceae) from South Australian mangroves [PDF]

open access: yes, 2019
A new genus of helotialean fungi, Annabella gen. nov. (Cordieritidaceae), is described to accommodate Annabella australiensis sp. nov. This species was collected on attached decaying wood of Avicennia marina, a common mangrove species found in protected ...
