  eLife Assessment

  Through cellular, developmental, and physiological analysis, this valuable study identifies a gene that regulates the relative growth of roots and shoots under salt stress. The holistic approach taken provides convincing evidence that this member of a larger tandemly duplicated gene family together with an upstream regulator contributes to salt tolerance. The manuscript will be of interest to plant biologists studying mechanisms of abiotic stress tolerance and gene family evolution.

  eLife Assessment

  This important study investigates the role of ATG6 in regulating NPR1, a key protein in the plant immune response. The authors present compelling evidence that ATG6 not only interacts with NPR1 in both the cytoplasm and nucleus but also enhances its stability and nuclear accumulation, leading to increased resistance to Pst DC3000/avrRps4 infection in Arabidopsis thaliana. The work incorporates a variety of approaches from molecular biology, confocal imaging, and biochemistry, which together strengthen the conclusions.

  This work presents the genome of Cardamine chenopodiifolia, an amphicarpic plant (developing two fruit types, one above and another below ground) in the mustard (Brassicaceae) family. Cardamines also known as bittercresses and toothworts. As an octoploid species it has been challenging to create a genome reference for this species, and in this case the authors finally managed to achieve this using PacBio HiFi long-reads and Omni-C technology to assemble a fully phased, chromosome-level genome. Obtaining a 597Mb genome assembled into 32 phased chromosomes (plus mitochondrial and plastid genomes), and only having one gap in the centromeric region of chromosome 9. Peer review asked for additional QC and benchmarking, helping demonstrate the genome quality was very high, with only one gap and a N50 of 18.80Mb. The data presented here potentially helping to develop this species as an emerging model organism in the Brassicaceae for studying the development and evolution of amphicarpy by allopolyploidy.

  eLife Assessment

  The authors demonstrated cellular heterogeneity of companion cells (CCs) and also suggested the CC subpopulation that highly expressed the florigen gene FT. Based on this finding, they further identified flowering time regulators acting in CCs, including small proteins and NITRATE-INDUCIBLE GARP-TYPE TRANSCRIPTIONAL REPRESSOR1 type proteins (NIGT1s). In particular, the authors propose the NIGT1-FT regulatory module, which may be involved in the response to nitrogen status. This important study advances our understanding of flowering time control at high spatial resolution. While we believe this work will be of broad interest to plant biologists, the supporting evidence remains in parts incomplete. In particular, the quality of the single-cell and bulk RNA-seq data needs to be addressed to solidify the conclusions.
