  Evaluation Summary:

  This manuscript provides a deep characterization of transcriptional regulation and conservation across key stages of complex multicellular development during mushroom formation. The authors present evidence for extensive allele-specific expression that includes many developmentally regulated genes that appear to have evolved recently. These findings help underscore how the tuning of gene expression and gains of new genes, the function of which will need to be unraveled in future, are likely the basis for the evolution of complex morphologies in fungi. This work should be of broad interest to evolutionary biologists, and especially to those studying the evolution of gene regulation.

• Curated by eLife

  Evaluation Summary:

  Nordén et al. examine feather iridescent color diversity across bird species. Their findings show how key modifications in feather melanosomes, pivotal nanophotonic structures, underlie the brilliant colors of iridescent feathers, broadening feather color range approximately twofold. In a next step, the authors evaluate the function of feather melanosomes by performing optical modelling of nanostructure diversity, evaluating up to 4500 distinct nanostructure combinations, which are then contrasted with the observed (color) spectral data from 120 plumage regions across 80 (diverse) bird species. This meticulous integration of diverse methods across a comprehensive dataset will not only inform biologists studying structural color biodiversity, but it may also inspire engineers designing nanophotonic systems.

  Evaluation Summary:

  This manuscript has the potential to be of broad interest to scientists seeking to understand the evolutionary dynamics of plants during past periods of rapid climate change. Specifically, within the target genus of Cochlearia, the results indicate increased rates of speciation and diversification in response to pronounced glacial cycles. Future work to establish more direct mechanistic links between the results and conclusions will improve our understanding of adaptation and speciation.

  Evaluation Summary:

  This work, which will be of value to evolutionary and clinical microbiologists, uses a well-designed experimental evolution strategy to tease apart contributions of history, chance, and selection on the evolution of antibiotic resistance in A. baumannii, an important microbial pathogen. While relevant, the work will benefit from further clarification regarding some of the concepts and procedures used and revision of some of the interpretations.
