  Evaluation Summary:

  The authors have produced a rich dataset that illuminates how root-associated bacteria differ among diverse maize lines, under low and high nitrogen treatment. The authors make use of this dataset to describe interesting patterns related to the genetic architecture of factors associated with maize rhizosphere microbiome assembly, although it is not clear yet whether the microbiome is an agent of natural selection in this case, or whether other selective forces shape maize roots in a manner that in turn affect smicrobiome recruitment. In addition to interesting insights reported in the present manuscript, these data are likely to be used for and/or compared to, in many future studies.

  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.
