Steroids are required for epidermal cell fate establishment in Arabidopsis roots.

Proceedings of the National Academy of Sciences of the United States of America - 12 May 2009

Kuppusamy Kavitha T, Chen Andrew Y, Nemhauser Jennifer L

Abstract excerpt

The simple structure of Arabidopsis roots provides an excellent model system to study epidermal cell fate specification. Epidermal cells in contact with 2 underlying cortical cells differentiate into hair cells (H cells; trichoblasts), whereas cells that contact only a single cortical cell differentiate into mature hairless cells (N cells; atrichoblasts). This position-dependent patterning, in combination with...
