Root layers: complex regulation of developmental patterning.

Journal Article (Review;Journal Article)

Developmental patterning events involve cell fate specification and maintenance processes in diverse, multicellular organisms. The simple arrangement of tissue layers in the Arabidopsis thaliana root provides a highly tractable system for the study of these processes. This review highlights recent work addressing the patterning of root tissues focusing on the factors involved and their complex regulation. In the past two years studies of root patterning have indicated that chromatin remodeling, protein movement, transcriptional networks, and an auxin gradient, all contribute to the complexity inherent in developmental patterning events within the root. As a result, future research advances in this field will require tissue-specific information at both the single gene and global level.
