DESCRIPTION:For a small and seemingly peripheral organ\, the root cap perf
 orms a remarkably large and diverse set of functions in root growth and de
 velopment. Given its role in many of the defining features of root growth\
 , the evolution of the root cap was probably a central event in the evolut
 ion of the root itself. The morphology and function of the root cap are ti
 ghtly connected\, and root cap development is therefore regulated with gre
 at precision. Recent work in Arabidopsis has begun to reveal the complex g
 enetic network that controls this developmental process. In particular\, t
 wo NAC-domain transcription factors\, FEZ and SOMBRERO\, are central to ro
 ot cap development\, and form a feedback loop which connects pattern forma
 tion\, stem cell activity and cell differentiation. In this talk I will de
 scribe our recent results regarding root cap development\, and discuss wha
 t implications they have for understanding the evolution of roots.
