Fig. 1From: Small Papillae Regulated by SPD25 are Critical for Balancing Photosynthetic CO2 Assimilation and Water Loss in RicePhenotypes of WT and spd25 mutant. (a) SEM images of the adaxial leaf surfaces in WT (left) and spd25 (right). T, trichome; St, stomata; SP, small papillae. Bars = 60 μm. (b) SEM images of the abaxial leaf surfaces in WT (left) and spd25 (right). MP, medium papillae; LP, large papillae. Bars = 150 μm. (c) Magnification of SP in (a). Bars = 6 μm. (d) TEM images of the epidermal cell wall in WT (left) and spd25 (right). Cu–Si, cuticle-silica double layer; Cy, cytosol. Bars = 10 μm. (e) Epicuticular wax and (f) silicon contents in WT and spd25 leaves. Shown are the mean ± SD from three biological replicates each containing ten plants. * and ** indicate P < 0.05 and P < 0.01, Student’s t-testBack to article page
