  eLife assessment

  This manuscript will be of interest to scientists who study cardiomyocyte homeostasis and contraction. It assesses the functional consequences of cardiomyocyte-specific knockout of Palladin, leading to the identification of a compensation mechanism when Palladin is deleted in embryogenesis, but not in adulthood. In addition, the authors identified new Palladin interactors, revealing a role for Palladin in the maintenance of intercalated disc structure.

Gene editing and scalable functional genomic screening in Leishmania species using the CRISPR/Cas9 cytosine base editor toolbox LeishBASEedit

  Only few species of Leishmania, an important human pathogen, have an RNAi machinery, alternative methods are needed for genetic screens. The authors resent and validate a valuable method, based on the introduction of premature stop codons, that can be used for several different species. The results are very convincing, the data are solid, and the approach will be of interest to researchers studying any eukaryote that lacks the RNAi machinery.

  This important study employs auxin-induced degradation to show that the TATA-binding protein (TBP) is not required for ongoing RNA polymerase II transcription nor heat-shock or retinoic acid-induced transcription, but that TBP is essential for RNA polymerase III transcription, with TBP-independent TFIID complexes being assembled and present at the transcription start sites of polymerase II-transcribed promoters. The evidence for the major claims is currently incomplete.

  eLife assessment

  Regulation of gene expression in many biological systems occurs either through a binary mode where gene expression is either on or off (digital regulation), or through an analog mode leading to a graded modulation of gene expression. In this manuscript, the authors report how these two regulatory modes are integrated into a one-way switch pattern to control the expression of the Arabidopsis floral repressor gene FLOWERING LOCUS C (FLC). They suggest that an analog regulation in the autonomous pathway precedes a digital regulation conferred by Polycomb silencing before cold exposure, and this temporal switch correlates with the strength of transcription at the FLC locus in different genetic backgrounds.

  eLife assessment

  This manuscript reports important and valuable new data about the intriguing role of the lncRNA Charme during cardiac development. Whilst the majority of claims are convincingly supported by the data, the evidence for the cardiac phenotype and the mechanism by which Charme/MATR3 interacts is currently incomplete and requires additional experimental support. This paper is of general interest to cardiac developmental biologists as well as to anyone studying non-coding RNAs.
