Uncovering Gene Regulatory Networks Controlling Plant Cell Differentiation.

The development of multicellular organisms relies on the precise regulation of cellular differentiation. As such, there has been significant effort invested to understand the process through which an immature cell undergoes differentiation. In this review, we highlight key discoveries and advances that have contributed to our understanding of the transcriptional networks underlying Arabidopsis root endodermal differentiation. To conclude, we propose perspectives on how advances in molecular biology, microscopy, and nucleotide sequencing will provide the tools to test the biological significance of these gene regulatory networks (GRN).
