Distribution of genes within the Arabidopsis root stem cell niche. a (left) Schematic of the Arabidopsis root stem cell niche. CEI cortex endodermis initials (blue), Protophlo protophloem (pink), Epi/LRC epidermis/lateral root cap initials (green), CSCs columella stem cells (purple), Xyl xylem initials (orange), QC quiescent center (yellow). (left) GFP marker lines used to transcriptionally profile stem cells. SCN stem cell niche; Scale bar = 20 µm. b 3D principal component analysis (PCA) of the stem cell transcriptional profiles. The x, y, and z axis represent the three largest sources of variation (i.e., three largest principal components) of the dataset. Small spheres are biological replicates, large spheres are centroids. Red—Non-stem cells (NSCs); Brown—SCN; Blue—CEI; Pink—Protophlo; Green—Epi/LRC; Purple—CSCs; Orange—Xyl; Yellow—QC; c Distribution of the 9266 stem cell-enriched genes across the stem cell niche. Enrichment criteria are q-value < 0.05 (from PoissonSeq) and fold-change in expression >2.
