Phenotypes of the EXG1 -overexpressing plants. a Wild type leaf blade. b, c Division of leaf blade observed in the Pubi-EXG1 #4 (b) and #13 (c) plants (Nipponbare). Arrows indicate divided small leaf blade. d Necrotic colour change in leaf blade of the Pubi-EXG1 #10 plant (Nipponbare). e, f A transverse section of the leaf blade with two lacunae in the midvein of the control plant (e) or the leaf blade with four lacunae in the midvein of the Pubi-EXG1 #18 plant (Taichung 65) (f). Asterisks indicate lacunae. g, h Simplified SEM observation of the surface of the leaf blade of the control plant (g) or the Pubi-EXG1 #18 plant (h). i, j Panicle of the control plant (i) and the Pubi-EXG1 #18 plant (j). k, l TEM observation of chloroplast of the leaf blade of the control plant (k) or the Pubi-EXG1 #18 plant (l). Arrows indicate plastogranules. m, n Cell wall of the control plant (m) and the Pubi-EXG1 #18 plant (n). Bars = 1 cm in (a) to (d), (i) and (j), 100 μm in (e) to (h), and 1 μm in (k) to (n).
