Dicyemida and Orthonectida: Two Stories of Body Plan Simplification.

Two enigmatic groups of morphologically simple parasites of invertebrates, the Dicyemida (syn. Rhombozoa) and the Orthonectida, since the 19th century have been usually considered as two classes of the phylum Mesozoa. Early molecular evidence suggested their relationship within the Spiralia (=Lophotrochozoa), however, high rates of dicyemid and orthonectid sequence evolution led to contradicting phylogeny reconstructions.

The Reduced Level of Inorganic Polyphosphate Mobilizes Antioxidant and Manganese-Resistance Systems in .

Inorganic polyphosphate (polyP) is crucial for adaptive reactions and stress response in microorganisms. A convenient model to study the role of polyP in yeast is the strain CRN/PPN1 that overexpresses polyphosphatase Ppn1 with stably decreased polyphosphate level. In this study, we combined the whole-transcriptome sequencing, fluorescence microscopy, and polyP quantification to characterize the CRN/PPN1 response to manganese and oxidative stresses.

Translatome and transcriptome analysis of TMA20 (MCT-1) and TMA64 (eIF2D) knockout yeast strains.

TMA20 (MCT-1), TMA22 (DENR) and TMA64 (eIF2D) are eukaryotic translation factors involved in ribosome recycling and re-initiation. They operate with P-site bound tRNA in post-termination or (re-)initiation translation complexes, thus participating in the removal of 40S ribosomal subunit from mRNA stop codons after termination and controlling translation re-initiation on mRNAs with upstream open reading frames (uORFs), as well as initiation on some specific mRNAs. Here we report ribosomal profiling data of strains with individual deletions of , or both and genes.

FACS Isolation of Viable Cells in Different Cell Cycle Stages from Asynchronous Culture for RNA Sequencing.

Recently developed high-throughput analytical techniques (e.g., protein mass spectrometry and nucleic acid sequencing) allow unprecedentedly sensitive, in-depth studies in molecular biology of cell proliferation, differentiation, aging, and death.

Evolution of the Genome 3D Organization: Comparison of Fused and Segregated Globin Gene Clusters.

The genomes are folded in a complex three-dimensional (3D) structure. Some features of this organization are common for all eukaryotes, but little is known about its evolution. Here, we have studied the 3D organization and regulation of zebrafish globin gene domain and compared its organization and regulation with those of other vertebrate species.
