The Dinophysis genus is an ecologically and evolutionarily important group of marine dinoflagellates, yet their molecular phylogenetic positions and ecological characteristics such as trophic modes remain poorly understood.

Probing complex RNA structures by mechanical force [PDF]
RNA secondary structures of increasing complexity are probed combining single molecule stretching experiments and stochastic unfolding/refolding simulations. We find that force-induced unfolding pathways cannot usually be interpretated by solely invoking successive openings of native helices.

The study uses prepared mock communities of three unrelated basidiomycete lineages, each containing carefully selected closely related species. Performance of the generally used fungal barcoding region ITS nrDNA is compared with two low‐copy protein coding regions (rpb2 and tef1a).

Slip of grip of a molecular motor on a crowded track: Modeling shift of reading frame of ribosome on RNA template [PDF]
We develop a stochastic model for the programmed frameshift of ribosomes synthesizing a protein while moving along a mRNA template. Normally the reading frame of a ribosome decodes successive triplets of nucleotides on the mRNA in a step-by-step manner.

The diversification of the Australian second‐wave Panesthia is strongly tied to the fragmentation of mesic forest from the Pliocene onwards. The Lord Howe Island cockroach Panesthia lata reached the island in a single colonization event and subsequently expanded its niche.

Extraction of RNA of high quality and integrity is essential for gene expression studies and all downstream RNA-based techniques. The leaves of 16 merit Malaysian rice varieties were used to isolate total RNA using five different methods.

Insights into the phylogeny of the ciliate of class Colpodea based on multigene data
In the class Colpodea, there are many unresolved evolutionary relationships among taxa. Here, we report 30 new sequences including SSU‐rRNA, ITS1‐5.8S‐ ITS2 rRNA, and the mitochondrial small subunit ribosomal RNA (mtSSU‐rRNA) genes of five colpodeans ...

Molecular interactions between the constituents of small ribosomal subunit [PDF]
Availability of high-resolution crystal structures of ribosomal subunits of different species opens a route to investigate about molecular interactions between its constituents and stabilization strategy. Structural analysis of the small ribosomal subunit shows that primary binder proteins are mainly employed in stabilizing the folded ribosomal RNA by ...

Physical modeling of ribosomes along messenger RNA: estimating kinetic parameters from ribosome profiling experiments using a ballistic model [PDF]
Gene expression consists in the synthesis of proteins from the information encoded on DNA. One of the two main steps of gene expression is the translation of messenger RNA (mRNA) into polypeptide sequences of amino acids. Here, by taking into account mRNA degradation, we model the motion of ribosomes along mRNA with a ballistic model where particles ...
