Single-cell laser ablation uncovers the blueprint of plant development.

PubMed · 2026-05-16

Scientists can now zap individual plant cells with a laser to watch—in real time—how neighboring cells respond, revealing the hidden rules that guide a plant from seed to structure.

Single-cell laser ablation combined with confocal microscopy enables precise, real-time manipulation of individual cells within intact plant tissues—something previously impossible.

The technology has revealed how signaling networks maintain meristems (the growth hubs that produce all new plant organs) and establish root patterning.

Laser ablation is being used to model wound responses and immune activation, showing how plants coordinate cellular communication following localized damage.
