  This study presents an important description on the dynamics of histone variant exchange controlling the organization of the chromatin state of the Arabidopsis genome, combining the analysis of histone variants, histone modification, and chromatin states. The evidence supporting the claims of the authors is compelling. This work will be of great interest to those in the field of epigenetics and chromatin biology.

  This is an important study that defines cell type changes upon the expression of a mutant tau protein and put it into context of human postmortem tissue. Technically, the single cell mRNA sequencing data are convincing but the loss of neurons already at the earliest stages assessed in this model may rather suggest there are also elements of developmental toxicity.

  Protein abundance is the result of many layers of regulation, including at the levels of transcription, mRNA stability, translation and protein degradation. Many transcripts contain short upstream ORFs (uORFS), but their effects on the translation of the main ORFs are difficult to predict as they are sometimes negative, positive and of different magnitudes. Here, the authors identify features of uORFs using massively parallel reporter assays, and these features help predict uORF effects on translation of main ORFs. The results will be an important resource for the community of researchers using this model organism and for the molecular and cell biology community in general as they allow to better understand how genes are regulated. There are also areas in which the authors' claims or conclusions are not fully justified and require either additional statistical analysis or new experimentation.

  In this useful study, a GWAS-type analysis is applied to clinical Mycobacterium tuberculosis isolates to discover genetic polymorphisms linked to poor tuberculosis outcomes. The evidence for the detected associations is still incomplete, as the corresponding polymorphisms are not adequate to power a prediction model for infection outcome, although key host factors - including patient age, sex, and duration of diagnostic delay (which have stronger predictive value) - appear to enhance predictive capacity.

  This important manuscript employs a rigorous and multi-pronged comparative genomics approach to unravel how lifestyle modulates the acquisition and domestication of viral genetic elements in the genomes of hymenopteran insects. Using an extensive dataset of over 120 hymenopteran genomes, the authors provide convincing evidence that endoparasitism (where parasite development occurs within hosts) facilitates the uptake and domestication of double-stranded DNA viral elements.
