Mature rootlets are covered in root hairs that are thought to function like mycorrhizae, and to have a competitive advantage due to their greater tolerance to low soil moisture and their rapid development in response to moisture (Lamont 1982, 1993).

Washington, Dec 15 (ANI): A new research by scientists from the University of Bristol in the UK has shown how to increase the length of root hairs on plants, potentially improving crop yields, as plants with longer root hairs take up minerals and water more efficiently.
