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.
1
Single-cell laser ablation combined with confocal microscopy enables precise, real-time manipulation of individual cells within intact plant tissues—something previously impossible.
2
The technology has revealed how signaling networks maintain meristems (the growth hubs that produce all new plant organs) and establish root patterning.
3
Laser ablation is being used to model wound responses and immune activation, showing how plants coordinate cellular communication following localized damage.
