Spizellomycespunctatusis a genetically tractable chytrid and model organism for comparative cell biology for understanding evolution of the cell cycle, actin dynamics, and cellularization in fungi and early eukaryotes.
Prdm9-generated meiotic asynapsis of homologous chromosomes in mouse subspecific hybrids causes hybrid sterility and can be reversed by introducing random stretches of consubspecific sequence (≥ 27Mb) on four chromosomes most sensitive to asynapsis.
Cell cycle network evolution in a fungal ancestor was punctuated by the arrival of a viral DNA-binding protein that was permanently incorporated into the regulatory network controlling cell cycle entry.
The exogenous DNA DSBs improve meiotic chromosome pairing in mouse inter-subspecific hybrids, thus providing an evidence for a DSB-dependent mechanism of the PRDM9-controlled synapsis failure and infertility.
A generally applicable two-hybrid assay demonstrates that MHC class I heavy chains devoid of beta-2 microglobulin associate within and across allotypes, with implications for endocytosis and autoimmunity.
Tn5 transposase has direct tagmentation activity towards RNA/DNA hybrids, which is harnessed as a more convenient and faster RNA-seq library construction method and will benefit RNA and chromatin research.
