Molecular phylogeny of symbiotic dinoflagellates inferred from partial chloroplast large subunit (23S)-rDNA sequences.
TLDR
Comparisons of sequence dissimilarity indicated that cp23S-rDNA Domain V evolves 9-30 times faster than the V1-V4 regions of nuclear small sub unit (n18S)-rDNA, 1-7 times as fast as the D1-D3 regions ofnuclear large subunit (n28S)- rDNA, and 0.27-2.25 times that of the internal transcribed spacer (ITS)-r DNA region.
GENETIC COMPARISONS OF FRESHLY ISOLATED VERSUS CULTURED SYMBIOTIC DINOFLAGELLATES: IMPLICATIONS FOR EXTRAPOLATING TO THE INTACT SYMBIOSIS
TLDR
RFLP data suggest that, in most cases, cultures are a subset of the original in hospite population, and reexamination of the literature revealed examples of zooxanthella cultures being nonrepresentative of in Hospite populations.
Inducible Expression, Enzymatic Activity, and Origin of Higher Plant Homologues of Bacterial RelA/SpoT Stress Proteins in Nicotiana tabacum*
TLDR
These findings implicate a direct mode of action of these ppGpp synthetases with regard to plant physiology, namely regulation of chloroplast gene expression in response to plant defense signals.
Phylogenetic analyses among octocorals (Cnidaria): mitochondrial and nuclear DNA sequences (lsu-rRNA, 16S and ssu-rRNA, 18S) support two convergent clades of branching gorgonians.
TLDR
Recon reconstructs genealogical relationships among some octocoral species based on published DNA sequences using information from insertions-deletions (INDELS) and the predicted secondary structure of the lsu-rRNA (16S) to support a hypothesis of independent evolution of branching in the twoOctocoral clades.
Transcontinental Phylogeography of the Daphnia pulex Species Complex
TLDR
It is found that the well-studied panarctic D. pulex is present on every continent except Australia and Antarctica, and there is a lack of strong regionalism in the mitochondrial genomes of panarctica D.pulex – a pattern that differs from that of most studied cladocerans.
Mature habitats associated with genetic divergence despite strong dispersal ability in an arthropod
TLDR
The evidence agrees with negligible gene flow after founding, and the accumulation of genetic divergence with habitat age, which challenges the notion that lacustrine populations of cladocerans are generally unified by contemporary gene flow.
Filoviruses are ancient and integrated into mammalian genomes
TLDR
The results show that the mammal-filovirus association is ancient and has resulted in candidates for functional gene products (RNA or protein) and the previous age estimate for filoviruses of less than 10,000 years is assessed.
Phylogenetic evidence for a single long-lived clade of crustacean cyclic parthenogens and its implications for the evolution of sex
TLDR
The sequence–based, structural rRNA and total evidence phylogenies are concordant and suggest that cyclic parthenogenesis arose once in the branchiopods, that this clade is long–lived, and that it has radiated extensively into nearly every aqueous habitat without reverting to strict sexuality and only rarely transforming to strict asexuality.
An assessment of accuracy, error, and conflict with support values from genome-scale phylogenetic data.
TLDR
Although the results demonstrate that caution is warranted concerning conclusions of conflict based on the assumption of underestimation for support values in real data, there was little evidence for widespread, strongly supported among-gene conflict from bootstraps.
Cryptic species within the Chydorus sphaericus species complex (Crustacea: Cladocera) revealed by molecular markers and sexual stage morphology.
TLDR
It is concluded that cryptic regional lineages of benthic cladocerans are apparent and that the sexual stages represent the most informative morphological source of species characters for this environmental indicator group.
