Extended Data Fig. 5: Single cell transcriptional changes in root meristem cells upon cytokinin treatment.

a-c. UMAP representation of the merged (a), mock (b) and cytokinin (c) datasets in which cell identities are shown by clusters of different colours. In panels b-c, the cells from the other dataset are indicated in grey to show contribution to each of the cell clusters. LRC: lateral root cap; PX: protoxylem; MX: metaxylem; SE: sieve element; CC: companion cell. The most central dark blue cell cluster is the initial cell cluster. d. Relative cell identity abundance in the mock and cytokinin (CK) datasets in comparison to a previously published root meristem atlas8. e,f. Violin plots showing normalized gene expression of CKX3 (e) and CKX5 (f) by cell type and split by treatment: left side of the violin is mock dataset in green; right side of the violin is CK-treated dataset in red).
