  Evaluation Summary:

  This manuscript reports that ppGpp accumulation is necessary for acclimation to nitrogen starvation in a model plant Arabidopsis. The authors also showed a ppGpp-mediated downregulation of chloroplast gene transcription and a coordinated plastid-nuclear gene expression under nitrogen deficiency. This represents a solid new step in our understanding of plant responses to nitrogen-limiting conditions as well as on the role of ppGpp in plants and possibly throughout the green lineage.

  Evaluation Summary:

  This work reports the structure of the photosystem I of Gloeobacter, a cyanobacterium that does not contain low energy absorbing chlorophylls, the so-called red forms. By comparing this structure to those of other cyanobacteria that contain red forms, the authors aim to identify the chlorophylls responsible for low-energy absorption in PSI. Their second aim is to understand the role of the red forms. The topic is interesting, the structural data are very good, but the conclusions regarding the role of the red forms are not supported by data.

  Evaluation Summary:

  Phosphoinositide phosphates (PIPs) are lipids that can convey distinct identities to different cellular membranes via different phosphorylation patterns. Here, Doumane and co-authors document the effects of the previously-characterized sac9 mutant, affecting a putative PIP-5-phosphatase in Arabidopsis, on PIP localization and endocytic trafficking. This work confirms that disrupting PI(4,5)P2 localization can affect endocytic trafficking in plants and will be of interest to the plant and cell biology research fields.

  Evaluation Summary:

  De la Concepcion and colleagues investigated the mode of co-evolution of plant immune receptor pair that functions as a unit to detect pathogen invasion and turn on immunity. The study shows that an allelic mismatch of a receptor paired from rice can cause autoimmunity in the absence of pathogen effectors, and this can be traced to polymorphisms that arose fairly recently. Overall the study provides insights into the co-evolution of paired receptors and supports that the paired receptors have co-evolved to prevent premature inactivation and enable strong activation in response to matching effectors.

A coupled mechano-biochemical model for cell polarity guided anisotropic root growth

• Curated by eLife

  Evaluation Summary:

  The paper describes the development of a mechano-chemical model for plant root development. As such, it presents a significant advance relative to other root models that have focussed predominantly on either the mechanical or auxin patterning aspects of root development, as evidenced by the potential of the model to reproduce a series of hormonal and mechanical perturbation experiments. The current conclusion that a set of minimal principles for self-organized root tip patterning is revealed must be moderated, as patterning inputs are essential to produce the reported observations.
