     Evaluation Summary:

     This manuscript describes a novel tool for tracking synaptic plasticity at the single synapse resolution with a SEP-tagged GluA1 receptor expressed in a transgenic mouse. The authors rather convincingly demonstrate that this tool does not disturb synaptic physiology or mouse behavior. They also show that this tool can be used to measure the distribution of synaptic weights and its variation during a plasticity protocol in barrel cortex. This tool is useful for more quantitative measurements of synaptic strength in vivo, although some revisions would help making a convincing case of the usefulness of this tool with respect to previous methods. Genetic specificity of the expression of the construct is also a concern.

     Evaluation Summary:

     This paper will be of interest across psychology and ecology. It attempts to replicate influential findings that imply Theory of Mind in food-caching decisions of Eurasian Jays. The authors' approach to both attempting to expand on and replicate earlier findings is both rigorous and thoroughly contextualized. The failure to reproduce earlier findings raises important questions for the field.

     Evaluation Summary:

     This work presented in this manuscript paper may advance our understanding of an important class of anti-viral drugs (nucleoside analogs) that target polymerase enzymes by being directly incorporated into the product strand. This class of drugs is known to be quite diverse in their precise mechanisms of action, yet many of the particular details have remained elusive, often due to experimental limitations. The current study employs a single-molecule magnetic-tweezers platform to provide a new paradigm for the mechanism of drug remdesivir against the SARS-CoV-2 polymerase target. The authors propose that remdesivir does not prevent the complete viral RNA synthesis but causes an increase of polymerase pausing and back tracking. This paper is of broad interest to readers and scientists working on SARS-CoV-2 and general nucleotide inhibitors. The work includes the single molecule characterization of other NAs.

     Evaluation Summary:

     Hwang et al. address the important question about whether specific thalamic sub-regions serve as essential "hubs" for interconnecting diverse cognitive processes. Using a group of patients with isolated thalamic lesions (n=20), and a group of size-matched lesions outside the thalamus (n=42), they report that lesions to the anterior-medio-dorsal thalamus are most likely to cause widespread cognitive deficit. Evidence from existing task-based and resting-state fMRI data sets, as well as data sets on gene expression further provide evidence the importance of these regions as a network hub for domain general cognitive functions.

     Evaluation Summary:

     How pollen apertures are formed is not well understood. By studying Arabidopsis mutants producing pollen with aberrant aperture numbers, the authors identify proteins from the ELMOD protein family as important regulators for aperture formation. They use genetics, transgenic constructs, and site-directed mutagenesis to pinpoint important residues for protein function in this process, and show that changes in expression levels of one protein can have dramatic effects on patterning. This paper will interest scientists interested in cell polarity, patterning, and evolution of diverse morphologies. This is also the first study of the ELMOD protein family, whose potential GTPase activating activities have not yet been investigated in plants.

     Evaluation Summary:

     Using single cell RNA seq, the authors characterize the sensory neuron microenvironment in dorsal root ganglia after sciatic nerve crush, dorsal root crush and dorsal column transection spinal cord injury 3 days after injury. The data revealed differentially expressed genes and pathways with sciatic nerve and dorsal root crushes co-clustering, whereas spinal cord injury largely co-clusters with uninjured. The results reveal influences of the tissue microenvironment and neuron extrinsic factors on axonal regeneration and also provide new insights into the role of PPARa signaling in regeneration after dorsal root crush. This is an impressive data collection effort across multiple cell types that will be of importance for generating new hypotheses in the field. The impact could be further broadened by increased attention to functional validation of the findings.

     Evaluation Summary:

     This is an interesting resource paper, describing the response of hematopoietic stem and progenitor cells to a few drugs commonly used to stress hematopoiesis. Transcriptomic analyses reveal interesting patterns, and the authors use ATAC-seq to investigate whether stem and progenitor subpopulations may be primed to respond in specific ways based on their chromatin accessibility. This turns out not to be the case when directly responsive genes are analyzed, and rather differences can be found in the promoter accessibility of genes further downstream.

     Evaluation Summary:

     This manuscript describes an analysis of cell type-specific alternative splicing using 10x scRNA-seq data. This work shows that in spite of the challenges associated with the analysis of such datasets, it is possible to identify alternative exons with differential splicing between tissue compartments and to some extent reveal cell types by splicing profiles of single cells. This work is informative regarding what can be done to analyse alternative splicing using 10X data and fills in a gap in the field.

     This paper will be of broad interest to chemists and biologists studying complex coacervate systems, including biomolecular condensates. Its model provides a new way of obtaining diffusion properties inside and outside the condensates without the necessity of nontrivial assumptions. The model's capability is well presented by applying to experimental data and through further investigating the model through simulations.

      Evaluation Summary:

      Many algae, such as Chlamydomonas, form a pyrenoid under certain conditions to enable high photosynthetic rates during inorganic carbon limitation. The data presented here support that hydrogen peroxide, a common by-product of hyperoxia and CO2 limitation, induces pyrenoid formation in Chlamydomonas, even when CO2 levels are high. Although the underlying genetic mechanisms remain unresolved, these observations offer an exciting starting point to dissect the molecular components that drive pyrenoid formation. Therefore, this paper is of interest to a broad audience of scientists working in the areas of photosynthesis, synthetic biology of agriculture, and algal biotechnology.
