Northern analysis showing Arabidopsis phyB (A.th. PhyB) and potato PhyB (S.t. PhyB) transcript levels in leaves of wild-type (Wt), Dara-5, and Dara-12 potato plants. Hybridization with a potato S4 probe was done to correct the signal for loading differences; 1.5 μg of poly(A+) RNA was loaded per lane.
