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...

New Article: "Root hair lifespan is antagonistically controlled by autophagy and programmed cell death" rdcu.be/fhdSG Autophagy negatively regulates senescence-induced programmed cell death to maximize the functional lifespan of root hairs. #PlantScience

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....

Thankful, happy and excited to be awarded an ERC consolidator grant to understand how and why some plants make stomata on their upper leaf surface. tuit.ut.ee/en/news/erc-... #ERCCoG @erc.europa.eu

ERC grant helps to understand why the upper and lower surfaces of plant leaves differ

Hanna Hõrak, Associate Professor of Molecular Plant Physiology at the University of Tartu Institute of Technology, has received a prestigious European Research Council (ERC) grant to study how cell pa...

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: https://scim.ag/3WgNajk

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

Hygrometrically controlled programmed cell death drives anther opening and pollen release | PNAS

The fantastic work of @kampova.bsky.social is finally out in PNAS: weather sensing and programmed cell death in anther dehiscence and opening. Cool science and awesome microscopy! @svosolsobe.bsky.social @handle.invalid @moritznowack.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/...
