Fig. 3. Induction of OsWOX13 by abiotic stressors.

(A) RT-PCR analysis confirmed that Os01g0818400/OsWOX13 were moderately up-regulated under drought stress in leaf and root. (B) Leaves of 14-d greenhouse-grown seedlings were collected directly (NC) or subsequently the whole plant was air-dried (dry) in a growth chamber. Another set was removed from soil to water and kept in a chamber at 28°C (H₂O), 42°C (heat) or 4°C (cold). Then, 400 mM NaCl was also added to the water to induce salt stress (salt). All leaves were collected after 3 h.
