A Dynamic Mobile DNA Family in the Yeast Mitochondrial Genome
This study assembled 28 complete yeast mitochondrial genomes and took advantage of the power of population genomics to determine mobile DNAs and their propensity and observed compelling evidence of GC clusters propagating within the mitochondrial genome and being horizontally transferred between species.
Extensive Horizontal Transfer and Homologous Recombination Generate Highly Chimeric Mitochondrial Genomes in Yeast.
The unexpectedly high frequency of mitochondrial HGT in yeast may be driven by frequent mitochondrial fusion, relatively low mitochondrial substitution rates and pseudohyphal fusion to produce heterokaryons, and there is a critical need to systematically study the frequency, extent, and importance of mitochondria HGT across eukaryotes.
Evolution of the IL17 receptor family in chordates: a new subfamily IL17REL
Sequence and structure analyses reveal functional similarities and distinctions between the different IL17Rs, and a group of IL17RE-like proteins were identified from mammalians to lower vertebrates, indicating that IL17REL may represent a unique subfamily of IL 17Rs.
Substrate-Specific Differential Gene Expression and RNA Editing in the Brown Rot Fungus Fomitopsis pinicola
It is found that culture conditions had a greater impact on global expression profiles than substrate wood species and the suites of genes subject to RNA editing were much less affected by culture conditions, highlighting the need for standardization of culture conditions in studies of gene expression in wood-decaying fungi.
Evolution of prokaryotic homologues of the eukaryotic SEFIR protein domain.
Evolution of substrate-specific gene expression and RNA editing in brown rot wood-decaying fungi
The extent to which gene expression and RNA editing differ among species and substrates is shown, and clues into mechanisms by which wood-decaying fungi may adapt to different hosts are provided.
Purification of a polysaccharide from Boschniakia rossica and its synergistic antitumor effect combined with 5-Fluorouracil.
Genetic Drift and Indel Mutation in the Evolution of Yeast Mitochondrial Genome Size
A positive correlation between mitogenome size and the level of genetic drift is observed, suggesting thatMitogenome expansion in yeast is likely driven by multiple types of sequence insertions in a primarily nonadaptive manner, and support an important role of genetic Drift in the evolution of yeast mitogenomes.
Evolution of a Record-Setting AT-Rich Genome: Indel Mutation, Recombination, and Substitution Bias
Ten complete mitogenomes of the Saccharomycodes ludwigii yeast with 8% G + C content are sequenced, suggesting existence of mechanisms other than AT-biased mutation operating to increase A/T, and new lights on mechanisms driving extremely AT-rich genomes are shed.
Origin and Spread of Spliceosomal Introns: Insights from the Fungal Clade Zymoseptoria
The dynamic invasion and proliferation processes of spliceosomal introns resemble the life cycles of mobile selfish (group I/II) introns, and these intron movements, at least in part, account for the dramatic processes of intron gain and intron loss during eukaryotic evolution.
