Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis!

Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...

Box 1. (shortened, full legend in paper): Key developments in understanding the role of CLE signalling in plant development. This scheme represents a summary on the selected latest advances in CLE signalling. (A) In a series of publications, Yuki Hirakawa and his team (Takahashi et al., 2021, 2023) characterized the CLE pathway in the liverwort Marchantia polymorpha that positively controls cell divisions via repressing the transcription factor JINGASA. (B) In Arabidopsis, CLV3/CLV1 signalling in the shoot was found to be buffering auxin-dependent development under different thermal conditions (John et al., 2023). (C) Research from several teams showed that the BAM3/CLE pathway is crucial for root protophloem development (Hu et al., 2018, 2022; Qian et al., 2022; Carbonnel et al., 2023). Moreover, the study by Carbonnel et al. (2023) identified an uncharacterized Arabidopsis CLE33 gene that acted in concert with CLE45 via BAM3 in root protophloem development.
🌱 EXPERT VIEW 🌱
In all land plants, small secreted peptides belonging to the CLE family move from cell to cell and activate their cognate receptors to control a plethora of developmental processes - Cornelis & Hazak
