  eLife assessment:

  This study adds a fundamental new perspective to a long-standing question: What controls the repair of photosystem II (PSII), a key process in maintaining and optimizing photosynthesis? The work supports a role for chemical modification in the recognition and subsequent degradation of a key protein subunit of PSII by a bacterial-type protease, suggesting that tryptophan oxidation of components of the photosynthetic apparatus after high light stress plays a critical role in initiating the PSII repair system. The evidence supporting the authors' conclusions is solid.

  **Editors Assessment: **

  Irises on top of being a popular and beautiful ornamental plant, have wider commercial interest due to the many interesting secondary metabolites present in their rhizomes that have value to the fragrance and pharmaceutical industries. Many of these have large and difficult to assemble genomes, and to fill that gap the Dalmatian Iris (Iris pallida Lam.) is sequenced here. Using PacBio long-read sequencing and bionano optical mapping to produce a giant 10Gbp assembly with a scaffold N50 of 14.34 Mbp. The authors didn’t manage to handle the haplotigs separately or to study the ploidy, but as all of the data is available for reuse others can explore these questions further. This reference genome should also allow researchers to study the biosynthesis of these secondary metabolites in much greater detail, opening new avenues of investigation for drug discovery and fragrance formulations.

  eLife assessment

  Secondary cell walls support vascular plants and conduct water throughout the plant body, and are crucial resources for lignocellulosic feedstocks. Here the authors present convincing genetic and biochemical evidence that secondary cell wall synthesis, known already to be under complex transcriptional control, is also controlled post-transcriptionally by MUSASHI-like RNA-binding proteins. These important results point to a new mechanism for control of secondary cell wall synthesis, which will be interesting to cell biologists and biochemists studying and attempting to manipulate plant biomass.
