Extended Data Fig. 6

a-b, Spatiotemporal expression of prMYB74:nlsGFP-GUS in AZs: (a) the Z-projected surface scan view from S15 to S17l and (b) the transverse section view from S14 to S17m. In b, the top panel shows GUS expression in RECs, and the bottom panel shows GFP expression in the receptacle from which images were obtained using light-sheet microscopy. Scale bars, 50 µm (top) and 100 µm (bottom). c, Expression of abscission-related genes (BOP2, HSL2, and QRT2) in multiple cell layers of AZs before and after abscission. Scale bar, 50 µm. d, Expression of MYB74 in the transverse and longitudinal sections from the abscission-defective mutants hae hsl2 and ida, respectively. Scale bar, 50 µm.
