Extended Data Fig. 7: RNA in situ hybridization of SGL1 in palm1 elp1 and pinna1 palm1 elp1.
From: A molecular framework underlying the compound leaf pattern of Medicago truncatula

a, Serial longitudinal sections of the palm1-3 elp1-3 P4 leaf primordium. b,c, Serial longitudinal sections of the pinna1-1 palm1-3 elp1-3 leaf primordia at P4 (b) and at P5 (c) stages. LP, leaf primordia. These experiments were repeated independently three times with similar results. Scale bars, 50 μm.
