highly significantp = 1.9 × 10 −118
The CytoTRACE score showed a weak but highly significant negative correlation with latent time (Spearman ρ = −0.25, p = 1.9 × 10 −118 ), indicating that, although capturing distinct facets of the transcriptome, the two orthogonal approaches suggested on a common developmental trajectory from mesophyll precursors toward terminally differentiated guard cells ( Tables S1 and S2 ). 3.2.
