  This study investigated the involvement of programmed cell death (PCD) in Arabidopsis thaliana root cap cells and its effect on microbial colonization. The authors have reported the importance of timely corpse clearance in the root cap and a root cap-specific transcription factor in controlling microbial colonization by beneficial fungi. By demonstrating the connection between transcriptional control of PCD and microbial colonization, this study provides fundamental insights into how relationships are established and regulated at the root-microbiome interface. The strength of the evidence presented is convincing, providing a foundation for further research concerning the spatial and temporal dynamics of microbiome recruitment along the root axis.

  This fundamental study provides convincing evidence for pectin modification as a requirement for RALF peptide signalling altering the apoplastic pH, adding further support for a key role of RALF peptides in linking the assembly and dynamics of the extracellular matrix with cellular activity and function. Data that have been added in comparison to a previous version have enhanced the study. The study should be of interest to anyone studying signaling and specifically to plant cell biologists.

  This paper provides important insights into the role of rice OsNF-YB7, an ortholog of Arabidopsis LEC1, in chlorophyll biosynthesis, uncovering the genetic and molecular basis for negative regulation of chlorophyll production in the rice embryo. Mutational analysis, gene expression profiles and protein interaction combine for convincing evidence that OsNF-YB7 represses chlorophyll biosynthesis.
