  Evaluation Summary:

  The authors make an important contribution to our understanding of the universal mechanism of unloading of sugars from the phloem (the vascular tissue dedicated to long-distance sugar transport in plants) into root tip cells. Specifically, the authors investigate the pores (called plasmodesmata) present in the cell wall separating phloem cells from those cells into which sugars get unloaded in roots, which they found to have the same characteristic structure in all plant species investigated. The physical properties of these particular plasmodesmata suggest that they are especially suited for efficient and selective phloem unloading. The paper is relevant for audiences studying plant physiology and development. There are a few criticisms of the modelling work.

  Evaluation Summary:

  The work describes the energetic constraints and preferred operating conditions of these "strategies" in particular on how nature has solved the problem of low energy "headroom'" required to prevent deleterious back reactions while maintaining efficient energy storage. The differences between the species are quite interesting and show that nature has evolved multiple solutions to fundamental limitations. Given the importance of understanding and improving the efficiency of photosynthesis, and the new insights revealed, the work will be of interest to a broad audience.

  Evaluation Summary:

  Beginning with transcriptome data, Rhodes et al. identify a new family of peptides with signalling function called CTNIP in the model plant Arabidopsis thaliana. They use an elegant biochemical capture approach to pinpoint the SERK-dependent LRR receptor kinase HSL3 as the only receptor for these peptides. They provide convincing genetic and biochemical evidence that HSL3 binds CTNIP and that CTNIP perception triggers HSL3-dependent cytoplasmic calcium influx, ROS production and transcriptional changes. Furthermore, they provide initial evidence that the CTNIP-HSL3 module may participate in regulating root growth.

On the capacity of putative plant odorant-binding proteins to bind volatile plant isoprenoids

• Curated by eLife

  Evaluation Summary:

  The chemical sensing mechanisms of plants, which are largely unknown, are a topic of broad interest. The authors hypothesise that plant chemical receptors may be transporter proteins or odorant binding proteins analogous to those found in animals. The authors have identified a list of plant proteins with possible odorant binding activity and they predict binding constants for relevant odorants. The calculated binding constants are generally very weak in comparison to known animal odorant binding proteins (i.e., would require much higher concentrations of odor for detection). The in silico investigation, while inspiring, leaves many open questions, for example whether or not there is evidence for functional analogy between plant and animal odorant binding proteins.

Plant Trans-Golgi Network/Early Endosome pH regulation requires Cation Chloride Cotransporter (CCC1)

  Evaluation Summary:

  Presented here is a study on the role of cation chloride cotransporter CCC1 as a key regulator of the plant Trans-Golgi/Early Endosome trafficking network. While the work is well controlled and presented overall, the reviewers judged the data supporting localization of CCC1 to TGN/EE as not being sufficiently clear, as was the role of CCC1 in endocytosis, which is one of the main conclusions. These points can be clarified with future careful experimentation.

Plant SYP12 syntaxins mediate an evolutionarily conserved general immunity to filamentous pathogens

• Curated by eLife

  Evaluation Summary:

  The study provides evidence that PEN1 and SYP122 regulate defense structures against filamentous pathogen infection including papillae formation and encasement of haustoria; this appears to be an ancient defense mechanism in land plants. If the findings that PEN1 and its close homolog SYP122 play an overlapping role in pre- and post-invasive immunity against cell-wall penetrating filamentous pathogens could be further validated, this would advance our understanding of callosic papilla/encasement-based nonhost defense mechanisms.
