Cooperative roles of OSR2 and other OSR genes in cell proliferation and expansion. (A) Morphology of 28-day-old WT, osr2 ARLi, osr2 argos-1 ARLi, and argos-1 osr1 ARLi OSR2i plants. Bar, 1 cm. (B-D) The leaf area (B), epidermal cell area (C), and estimated epidermal cell number (D) of the third leaves of the 30-day-old plants described in (A). At least five leaves were examined for each genotype; the data are shown as mean values ± SE; the letters (a to d) indicate statistical significance (P < 0.05) among the genotypes according to one-way ANOVA testing (SPSS 13.0, Chicago, IL, USA). (E, F) The cellular kinetics of developing third leaves of WT and osr mutant plants. The epidermal cell size (E) and estimated epidermal cell number (F) are shown as the ratio of mutant/WT from 9–27 day-old plants. At least five leaves of each genotype were examined.
