Morphological and cytological characterization of pro35S:OSR2 transgenic plants. (A) Morphology of 28-day-old control and three independent lines of pro35S:OSR2 transgenic plants (L1 to L3). Bar, 1 cm. (B) Blade areas of fully-expanded third leaves of control and three pro35S:OSR2 transgenic lines. At least five leaves for each genotype were examined; data are shown as mean values ± SE; Student’s t-test: **P < 0.01. (C) qRT-PCR analysis of OSR2 expression in control and transgenic plants presented in (A). The data were from three biological replicates and are presented as mean values ± SE; Student’s t-test: **P < 0.01. (D, E) The cell area and estimated cell number of epidermal cells in fully-expanded third leaves of control and three pro35S:OSR2 transgenic plants described in (A). At least five leaves were examined for each line, and data are shown as mean values ± SE; Student’s t-test: **P < 0.01. Bar, 50 μm. (F, G) The cell area and estimated cell number of mesophyll cells in fully-expanded third leaves of control and pro35S:OSR2 (three lines) transgenic plants. Bar, 50 μm. Data are shown as mean values ± SE; Student’s t-test: **P < 0.01.
