MUTE drives asymmetric divisions to form stomatal subsidiary cells in Crassulaceae succulents Crassulaceae MUTE guides asymmetric divisions to form stomatal subsidiary cells in succulents.

Very interesting paper-- evolutionary redeployment of MUTE to generate unique CAM plant (Kalanchoë) stomatal complex. From Raissig Lab, Sci Adv 🌵

In our new pre-print, we established massive single-cell RNA-sequencing for diatoms to investigate key cell fate transitions. Notably, we discovered that the diploid-to-haploid transition is regulated by Myb TFs, a process that is actively ongoing across the Global Ocean! 🌊

Plant hormone and peptide signaling converge in the genetic network regulating cambium activation in Arabidopsis roots An intertwined network of cytokinin, auxin and peptide hormone signaling activates secondary growth in the Arabidopsis roots.

After a long journey, our new paper is out! 🌱
In this study, Tiina and colleagues show that cambium activation in the Arabidopsis root is triggered by the induction of auxin, cytokinin, and TDIF peptide signalling. 🧵1/x doi.org/10.1093/plce...

Nanodomain-localized formin gates symbiotic microbial entry in legume and solanaceous plants Colonization of plant roots by symbionts requires substantial morphodynamic reorganization. Examples are actin-scaffolded microcompartments called infection pockets formed during root nodule symbiosis...

Happy to share our latest work in collaboration with the lab of @pengbo10.bsky.social. Here, we describe that a formin protein mediates the polarity switch from root hair to infection thread growth during symbiotic interactions.

Overview of dPCD processes during plant life cycle. Instances of dPCD (developmental programmed cell death; skull and crossbones) occurring during vegetative (A-D) and reproductive (F,E) plant development, and senescence (G). (A) In vegetative tissues, dPCD occurs during xylem differentiation, which progresses sequentially through stages of (i) cell specification, (ii) secondary cell wall deposition and lignification, and (iii) cell death and protoplast clearance. (B) Root cap turnover in Arabidopsis. The lateral root cap (LRC) and columella are indicated in purple and brown, respectively. (C) Leaf perforation in some taxa. (D) Lysigenous aerenchyma formation. (E) dPCD is involved in reproductive development in the fully grown plant. During sexual reproduction (i), dPCD occurs in nurturing layers such as the anther, tapetum and ovule nucellus, during anthesis, during functional megaspore (FM) selection and in antipodal cells of some species. During pollination and fertilization (ii), it occurs as part of the self-incompatibility response in some taxa, in the transmitting tract, and in the pollen tube and synergid cells to facilitate fertilization. (F) During seed development, dPCD occurs: (i) in the suspensor; (ii) in the embryo-surrounding endosperm, or the endosperm-adjacent-to-scutellum (EAS) region; and (iii) during seed coat formation and in the aleurone layer during germination. DAP, days after pollination. (G) dPCD is the terminal phase of senescence. Created in BioRender. Pitsili, E. (2026) https://BioRender.com/uo9f4fn. Republished with permission.

Thanks so much @degradomics.bsky.social for hosting me , I had a great time and very captivating discussions with @ottlab.bsky.social @lauraragni.bsky.social @kleinevehnlab.bsky.social and many others . What an amazing place to do (plant) research!

A question of death ☠️ and life 🧬

Yesterday we hosted @moritznowack.bsky.social (from Ghent University and @viblifesciences.bsky.social), their research on root caps uncovers the gene regulatory and molecular mechanisms coordinating differentiation with developmentally programmed cell death.
