  eLife Assessment

  This is a fundamental cell biological study of host responses during symbiotic microbial infection of plants. Compelling imaging-based approaches using genetically encoded cell cycle markers show that in Medicago truncatula root cortex cells, early rhizobial infection events are associated with cell-cycle re-entry, but once the infection is established, host cells exit the cell cycle. The work will be of interest to a wide range of readers working in fields from development and cell biology to plant-microbe interactions.

  Thick multicellular plant samples provide unique challenges when it comes to cryo-preservation, which has resulted in limited successful examples for structural studies using in situ cryo-electron tomography. To address this deficiency, this important study describes procedures for high-pressure-freezing, focused ion-beam milling, and cryo-electron tomography imaging of certain plant types. The results described in the paper provide solid evidence for the usefulness of the methods described, although some reservations remain about the applicability of the methods to a wider range of plant cell types.

  This valuable study shows that mutations in specific cassava genes can reduce infection by cassava brown streak viruses. The authors also identify a key amino acid change that may be significant in how the virus interacts with the plant, but its role is not yet confirmed. While the findings are promising for developing resistant cassava varieties, in the absence of testing a quadruple mutant and without more data on the critical importance of amino acid L5 in VPg-eIF4E interactions, the evidence for several of the major claims remains incomplete.
