Extended Data Fig. 8: REV expression before p0 is limited to inner tissues.
From: Specification of leaf dorsiventrality via a prepatterned binary readout of a uniform auxin input
The pattern of pREV:REV-YPet expression at the shoot apex showing weak internal REV accumulation just apical to p-1. Top view of the meristem (a) and optical longitudinal section at p-1 (b). Progenitors for the adaxial (yellow), abaxial (blue), and middle (not present at this developmental stage) domains were discerned by backward lineage tracing. Asterisks, meristem centre. Cell walls were stained by PI. Scale bars, 50 µm. Representative data from n = 7 apices (a), and n = 5 primordia (b) is shown.
