Figure 7. HRB1 action requires a functional PP7 during water loss.

Figure 7

Water loss was measured in detached leaves from 4-week-old plants under blue light supplemented with 25 µmol/m2/s red light for 2 hours and calculated as the percentage of their initial fresh weight. (A) Water loss of hrb1 plants is significantly different from that of Ws under 0.28 and 0.58 µmol/m2/s blue light (P<0.005, n = 10 and hereafter). (B) Water loss of hrb1 or 35S::PP7:MYC in hrb1 (PP7OE hrb1) is significantly different from that of Ws or 35S::PP7:MYC in Ws (PP7OE Ws) under 0.28 and 0.58 µmol/m2/s blue light (P<0.005). (C) Water loss of pp7 is significantly different from that of Col under all blue light intensities except 6.06 µmol/m2/s (P<0.005). Water loss of 35S::HRB1:MYC in Col (HRB1OE Col) is significantly different from that of Col under 0.28 and 0.58 µmol/m2/s blue light (P<0.005) and from that of 35S::HRB1:MYC in pp7 (HRB1OE pp7) under 0.28 µmol/m2/s blue light (P<0.05).
