  This boundary-crossing work on dandelion diaspore flight is an excellent demonstration of how to address fundamental questions about wind dispersal of plant seeds from biophysical and ecological perspectives. Both wind-tunnel experiments and models provide compelling evidence that the aerodynamics of dandelion diaspores change with the environment. Addition of local climate data enables the authors to make a convincing case about how the biophysical properties can scale up to affect dispersal across the landscape under different environmental conditions. In addition to the strong data, this is a clear, accessible, and very enjoyable read.

  This manuscript characterizes the localization and function of two proteins promoting division asymmetry in developing stomata of the grass Brachypodium distachyon. The authors demonstrate that the opposing polarity domains of these proteins are linked to cell division orientation. While both proteins have been studied previously in other systems, there was no prior evidence of cooperative functions in a single cell type, as shown here. With further clarification of some of the localization findings, this study will be of strong interest to plant cell biologists and those interested in asymmetric cell division generally.

  This paper, of relevance to a broad range of plant biologists and colleagues in the circandian field, reports important results that demonstrate circadian coordination of characteristic floral development in sunflower. The current manuscript includes convincing observations and possible hypotheses, but the ecological relevance of the temporally-controlled flower development is incompletely shown.

  Evaluation Summary:

  Engineering NLR proteins to improve disease resistance in crop plants is a major goal of the field. This study applies knowledge from structural and evolutionary studies of the rice NLR protein Pik-1 and cognate effector protein AVR-Pik to engineering of new disease resistance genes. The authors nicely demonstrate that it is indeed possible to engineer resistance proteins with broad recognition specificity for the rice blast fungus. The work is of interest to colleagues in synthetic biology, protein engineering and plant-pathogen interactions.

  Evaluation Summary:

  This manuscript, of interest to those studying the evolution of immunity, investigates the evolutionary history of a recently described herbivore-associated molecular pattern (HAMP) receptor, INR, which perceives the caterpillar-derived peptide HAMP, In11. The authors compare INR homologs to identify evolutionarily conserved residues and use chimeric fusion proteins to investigate specificity. The findings presented are valuable and supported by convincing experiments and analysis.

  This work, which will be of interest to all who study plant-microbe interactions as well as plant cell biology, addresses a fundamental question in symbiosis, placing a classic nodulation defective mutant (rpg) into a plausible protein complex and establishing a hierarchy of "infectosome" assembly. Evidence includes convincing genetics and subcellular localization of components during establishment and maintenance of infection. The study also includes compelling new FLIM-based imaging techniques to distinguish signals from closely associated domains in plant cells.
