  Evaluation Summary:

  In this manuscript, of interest to the fields of animal immunity and epigenetics, the authors investigate the crosstalk between PML Nuclear Bodies and HIRA, a member of the H3.3 histone chaperone complex, during inflammatory stress. This study raises interesting perspectives on how availability of HIRA could be regulated by PML Nuclear Bodies for histone deposition onto interferon-stimulated genes, which in turn, could be relevant for immune-response mediated gene regulation.

  Evaluation Summary:

  DNA double-strand breaks are a major threat to genome stability. In this study, the roles of two DNA repair proteins, Brc-1 and Smc-5, are investigated in C. elegans meiotic cells, to investigate the DSB repair pathways using the homolog or the sister chromatid as template . The results highlight a regulatory role of Brc-1 and Smc-5 as repressors of repair with the sister chromatid. The experiments are generally well executed, and the findings will be of interest to the DNA repair and C. elegans meiosis communities.

  Evaluation Summary:

  This study identifies an important role for a lytic polysaccharide monooxygenase in allorecognition in the filamentous fungus Neurospora crassa, which is independent of the catalytic activity of this remarkable class of proteins. The study's findings are strongly supported through an interdisciplinary approach, combining microscopy with genetics and biochemistry. The study will be of great interest to fungal biologists and microbiologists, as well as biochemists studying carbohydrate-active enzymes.

Limitations of principal components in quantitative genetic association models for human studies

• Curated by eLife

  Evaluation Summary:

  This simulation study is of interest to geneticists, especially those carrying out Genome-wide Association Studies (GWAS). It compares two major approaches for dealing with "population structure"in GWAS: Principal Component Analysis (PCA) and Linear Mixed-effects Models (LMMs). This is a subject of considerable practical importance and the study nicely reviews the theoretical underpinnings and concludes - based on the review and the extensive simulations - that there is every reason to believe LMMs to be superior (although PCA is more widely used). Although this point has been made before, it is worth making again given the ubiquity of these analyses. There are some concerns about the general validity of the claim given that the simulations fail to address several real-world problems.

  Evaluation Summary:

  Interactions between transposons and the Drosophila host genome are governed by dedicated H3K9me3-enriched loci that are selected for producing anti-transposon piRNAs through binding by the HP1 variant Rhino in Drosophila. The authors identify Kipferl, a ZAD zinc-finger protein, as helping to guide Rhino to G-rich motifs found at piRNA-producing loci in the female germline. The work thus reveals the involvement of a factor binding specific DNA sequences in piRNA biogenesis. The findings are of broad interest to the fields of heterochromatin and transposon biology.

  Evaluation Summary:

  This paper is one of the first demonstrations that expression quantitative trait loci (eQTL) affecting human microRNAs are linked to brain development affecting brain structure and function. These findings will have a broad impact on the genomics, neural development, and microRNA fields. The datasets produced here (developmental changes in miRNAs, new human miRNAs) will likely be used for further discoveries. However, some claims need to be tempered.

  Evaluation Summary:

  This paper presents a novel and potentially highly useful approach to monitor circadian rhythms in specific tissues. The elegant reporter that the authors have built has the potential to become an important tool for understanding how different body clocks respond to various inputs and genetic manipulations. The authors already apply it to show that different clocks appear to be responding differently to loss of signaling from a key circadian neuropeptide in Drosophila melanogaster. However, it is difficult to determine whether these results, as currently presented and analyzed, provide new insight into the relationship between brain and peripheral clocks. The work is of interest to the community of biologists studying biological rhythms.

  Evaluation Summary:

  This paper will be of interest to scientists interested in intergenerational transmission of phenotypes through genetic pathways. The authors propose an innovative and sound method to leverage the adoption of a design for disentangling prenatal and postnatal genetic effects. Additional analyses are needed to address the limitations of the model applied to the specific dataset that was used to illustrate the method.
