Solanoideae crops share similar stem anatomy. (A–D) Representative images of seedlings at the time of grafting. (E–H) Confocal micrographs show transverse stem sections taken from the location of grafting. (I–L) ×4 zoom of vascular cambium. Solanum lycopersicum (tomato; A, E, I), S. melongena (eggplant; B, F, J) Capsicum annuum (pepper; C, G, K), and Physalis pubescens (groundcherry; D, H, L) are all members of the Solanoideae subfamily. (E–L) were stained with propidium iodide and cleared in methyl salicylate prior to confocal imaging. Replication can be found in Supplementary Fig. S1. (A–D) Scale bar=2 cm, (E–H) scale bar=1 mm, (I–L) scale bar=250 um.
