  Satake and colleagues' important study elucidates somatic mutation processes in plants, demonstrating that in two tropical trees, mutation rates correlate with age, not growth rates. Their convincing evidence shows that many mutations do not align with cell divisions, suggesting many somatic mutations are generated in a replication-independent manner. This study represents a significant step towards advancing our understanding of plant development and the patterns and inheritance of mutations. This significant research is poised to engage a diverse array of scholars in plant evolution and development.

  This is a valuable study of the molecular basis of summer-to-winter transition in the pear psyllid pest, Cacopsylla chinensis (hemiptera). The molecular and organismal experiments using current methodologies to evaluate the cold responsiveness of the target proteins are mostly convincing, but the structural and phylogenetic analyses remain inconclusive. The results of this study will be of interest to entomologists.

  This paper provides important insights into how asexual reproduction can arise in interspecific hybrids. The evidence supporting the conclusions is compelling, with rigorous molecular cytogenetic experiments showing the production of clonal gametes is common across hybrids between closely to moderately divergent sexual species. By highlighting the potential for asexuality to evolve in hybrids during a narrow window of species divergence, this work will be of broad interest to evolutionary biologists.

Coevolution of the CDCA7-HELLS ICF-related nucleosome remodeling complex and DNA methyltransferases

  This important manuscript reveals signatures of co-evolution of two nucleosome remodeling factors, Lsh/HELLS and CDCA7, which are involved in the regulation of eukaryotic DNA methylation. The results suggest that the roles for the two factors in DNA methylation maintenance pathways can be traced back to the last eukaryotic common ancestor and that the CDC7A-HELLS-DNMT axis shaped the evolutionary retention of DNA methylation in eukaryotes. The solid evolutionary analyses form a strong basis for experimental follow-up studies. The work should be of interest to colleagues in the fields of evolutionary biology, chromatin biology and genome biology.

  This important study describes a high performance computational approach to interrogate how microscopic epistasis and clonal interference affect evolutionary dynamics in a spin glass model of microbial evolution. The study offers several insights that can aid in our understanding of the forces that operate in adaptive evolution. The evidence provided is compelling, with its rigorous use of models and analytical descriptions of how these forces manifest in evolution.

  This study reports an important theoretical model with simulations of meiotic recombination hotspots and Prdm9 evolution. By integrating recently identified biological properties of Prdm9, the model provides compelling evidence for novel features of hotspots and Prdm9 evolution. Yet, the model, the different steps in implementing parameters, and the predictions are difficult to follow and would benefit from clarification.

  This important study expands on current knowledge of allosteric diversity in the human kinome by C-terminal splicing variants using as a paradigm DCLK1. The authors provide convincing evolutionary and some mechanistic evidence how C-terminal isoform specific variants generated by alternative splicing can regulate catalytic activity by means of coupling specific phosphorylation sites to dynamical and conformational changes controlling active site and substrate pocket occupancy, as well as protein-protein interactions. The data will be of interest to researchers in the kinase and signal transduction field.
