Extended Data Fig. 7: Localization of TDC (a) and G10H (b) mRNAs in developing leaves using RIH.

Paraffin-embedded serial cross-sections from 1.8–2.0 cm leaves were hybridized with digoxigenin-labeled transcripts. Sections were hybridized with antisense and sense RNA probes. base, leaf base; middle, the middle area of the leaf at a distance of 6 mm from the base; tip, the tip portion of the leaf at 11 mm from the base; le, lower epidermis; ue, upper epidermis; pm, palisade mesophyll cells; sm, spongy mesophyll cells.
