Fig. 2: AN4 and DPL expression patterns.

a, b Spatial expression pattern of AN4 and DPL in the opening flower of MD. c Annotation of flower developmental stages in MD; scale bar = 1 cm. d Temporal expression patterns of AN4 and DPL during flower development in MD. SAND was used as the reference gene. Shown are the means ± SDs, n = 3. Asterisks indicate a significant difference: *P < 0.05; **P < 0.01; nonsignificant (NS). e Annotation of different parts of the flower in MD; scale bar = 1 cm
