Fig. 5. Northern analysis of the expression of VHb (Vitreoscilla hemoglobin gene) and tzs (trans-zeatin secretion gene) in T₁ plants. Lanes: X-1-1(k), Q-2-1(k), H-1-1(k), and Y-1-1(k) in (A) and (B) were loaded with 20 µg total RNA from kernels of T₁ plants; Lanes: X-1-1(p), Q-2-1(p), and H-1-1(p) in (B) were loaded with 20 µg total RNA from pistils of T₁ plants; Lanes: C(k) and C(p) were loaded with 20 µg total RNA from kernels and pistils of nontransformed control respectively. X stands for ‘Xiushui-11’, Q for ‘Qiufeng’, H for ‘Hanfeng’, and Y for ‘Youfeng’.
