Fig. 2.

Western blots of membrane fractions prepared from seven different Arabidopsis lines and probed with anti-PHOT2 antibody. Note that the transformant lines 5-a, 5-c and 5-d express levels of PHOT2 far below those of the wild type (gl1) or phot1-5. Lines 5-a and 5-d do not appear to express more protein than the phot1 phot2 double mutant although line 5-d does show some limited complementation (see text).
