- Title
A compact topic: How ethylene controls crown root development in compacted soil.

- Abstract
This article discusses the impact of compacted soil on crown root development in plants. Compacted soil, which is often overlooked, limits the availability of water and nutrients and makes it difficult for roots to penetrate deeper soil layers. The study shows that roots can sense soil compaction through the hormone ethylene, which inhibits root growth. However, ethylene also promotes the outgrowth of crown roots. The researchers identified a gene called OsWOX11 that is regulated by ethylene and plays a role in crown root development. Manipulating ethylene-related regulators can influence both root development and grain yield. Overall, the findings suggest that ethylene helps plants adapt to compacted soil by promoting the development of crown roots, which can access nutrients in the less compacted upper soil layer.
