Our new Nat Plants paper introduces WALLΦ, a genetically encoded cell wall pH sensor, and reveals that root developmental zonation is independent of local cell wall pH. Wall pH supports growth at the organ level, but local growth patterns are governed by other mechanisms. doi.org/10.1038/s414...

In this Primer, @eugeniapitsili.bsky.social and @moritznowack.bsky.social discuss the cellular and molecular frameworks governing the initiation and execution of programmed cell death in plants: doi.org/10.1242/dev....

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.

Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other. Learn more in this week's issue: scim.ag/3WgNajk

A confocal microscopy image shows root-colonizing bacteria clustering around an emerging lateral root, where localized glutamine leakage induces spatially confined reporter activity.

Intracellular pathogens can form extensive hyphal structures. Here, the pathogen Phytophthora palmivora (magenta) produces invasive hyphae in a living epidermal cell of a Nicotiana root. The plant surrounds the invader by an 'extra-invasive hyphal membrane' (yellow)📸 @alexguyon.bsky.social

Stomatal transpiration and rapid programmed cell death ☠️ triggered by lowered ambient humidity causes anther tissue collapse for effective pollen release ! Happy to be part of this great PNAS story with @kampova.bsky.social, Matyáš Fendrych, and @svosolsobe.bsky.social! www.pnas.org/doi/10.1073/...
