- Many plants often show twisted, corkscrew root growth.
- Root twisting helps plants move around stones in soil.
- Scientists asked how roots twist in nature.
- They used a small model plant system in the lab.
- Researchers put a normal gene into different layers of the root.
- When inner layers had the gene, roots stayed twisted.
- When only the outer layer had the gene, roots grew straight.
- The outer root layer controls the whole organ shape.
- This finding could help crops in rocky soil and drought.
