Fig. 4. Seedlings of transgenic rice under dehydration and OsWOX13 expression pattern.

Seeds were germinated in soil (12 seeds/5x5x6 cm pot). Drought stress was conducted by water-withdrawal for 1 day in 2-week-old seedling followed by rewatering for 2 days (A). Leaves were collected, and the expression of OsWOX13 was examined (B). Bands were quantified and divided to assess the corresponding ubi to obtain the relative ratio to ubiquitin given as the number under each band. Given that ubi is the constitutive primer, all bands of ubi were calibrated to 1.00.
