In a recent feature for BBC Gardeners' World, Prof Malcolm Bennett explained how plant hormones control the transition from dormancy to growth. "If the conditions are right, gibberellic acid dominates and starts growth," he says, as the seed absorbs water and the embryonic root begins to emerge.

How do roots decide where to grow? New research reveals: ⚡ Calcium signals trigger ROS bursts ⚖️ These balance gravity + mechanical resistance 🌍 Result: roots navigate soil more effectively By tuning cell wall stiffness, plants “feel” their way through the ground. hydrosensing.eu/2026/04/calc...
Image: Gravitropic bending of the rbohc/f mutants and their relative apoplastic pH in the elongation zone. (A) Root gravitropic bending of WT, mca1, cngc14-2, and rbohc/f mutants. Right-expression of bending as linear regression slope after 1 h of bending. Letters denote statistical significance (ANCOVA test of equal slopes p<0.002) (B) Representative images of the apoplastic pH halo in WT and rbohc/f mutants during the course of root gravitropic bending. Red dotted circles highlight the top side of the root with visible alkalinization in WT. (C) Apoplastic pH quantification of the rbohc/f and cngc14-2 mutants at the top and bottom elongation zones 90-160 minutes after rotating the sample by 90°. (one-way ANOVA, p<0.0001)(D) Calcium profile of WT plants during the course of gravitropic bending imaged immediately after rotating the sample, monitored using the GCaMP3.0 fluorescent reporter. The blue arrow marks the initial drop in the calcium signal from the top (upper) side of the root associated with statoliths leaving the membrane in the columella, while the orange arrow marks the increase in the calcium signal at the bottom (lower) side after the statoliths touch the new bottom membrane. The red arrow highlights the increase in the calcium signal at the upper side associated with root bending, which appears at the onset of root bending.

New manuscript out in Cell Reports! Shani lab has develope a multiplexed, tissue-specific CRISPR toolbox for Arabidopsis that overcomes gene family redundancy & enables large-scale,cell-type-resolved genetic screens 📃 www.cell.com/cell-reports... @eilonshani.bsky.social @cellpress.bsky.social
Level 1: the algorithm includes improved scoring functions for the design of efficient sgRNAs. Level 2: design and construction of multiplexed CRISPR libraries. Level 3: trait-oriented CRISPR libraries—nutrient uptake sub-libraries as a proof of concept. Level 4: tissue-specific CRISPR vectors for spatial genetics screens. Level 5: CRISPR-GuideMap: plant barcoded screens of ∼1,000 plants, allowing large-scale reverse genetics multi-knockouts. Outcome: a next-generation tool for plant genetics.

Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included. www.science.org/doi/10.1126/...

Glad to introduce our new logo 🎉 This new image reflects our mission: understanding how #plants perceive and respond to water stress — a step toward developing crops resilient to drought and #climatechange 🔗 hydrosensing.eu The image tells a story: 1/3 👇
The logo of the Hydrosensing project symbolically and conceptually represents the scientific goals of the initiative, which focus on how plants perceive and respond to water stress.

The image is framed within a water droplet, an element that directly references water as both a vital resource and the main subject of study. Inside the droplet, a plant with two green leaves grows from the center, symbolizing plant life and its interaction with water availability.

The lower half of the droplet is vertically divided into two distinct sections:

    The left half, in blue, represents a moist or well-irrigated environment.

    The right half, in brown and ochre tones, suggests a dry soil or drought conditions.

Roots extend downward from the plant's central stem into water, visually conveying the concept of a plant sensing and responding to different levels of water availability.

The design visually reinforces the mission of the Hydrosensing project: to understand the molecular and physiological mechanisms by which plants perceive water stress, with the aim of contributing to the development of crops that are more resilient to climate change.

In @uniofnottingham.bsky.social ERC Hydrosensing members spent a few intense (and wardrobe-consistent 😅) days filming about research on root systems and how plants adapt to drought. More footage for the documentary is being filmed at locations around the world in the coming year.
