Colour tracing of a confocal longitudinal section of an Arabidopsis root tip and a magnification of the RSCN. (A) Cleared root tip of Arabidopsis thaliana. The expected stable gene configurations that characterise each cell type are distinguished with different colours. As observed, some of the expected attractors represent more than one cellular type. QC, quiescent centre; END, endodermis; VI, vascular initials; CEI, cortex-endodermis initials; COR, cortex; PVC, peripheral vascular cells; CLEI, collumela-epidermis-lateral-root-cap initials; LCC, collumela and lateral root cap; and CVC, central vascular cells. (B) Amplification of the RSCN.
