Hypocotyl Lengths of Arabidopsis Seedlings Expressing Chimeric Phytochromes under R.

(A) Hypocotyl lengths of seedlings grown under R (3.3 μmol/m²/s) for 5 d. The hypocotyl lengths are presented relative to the dark (D). Data are the means ± se (n = 25). Ler, Landsberg erecta.

(B) The relationship between hypocotyl length under R (ordinate) and protein expression levels (abscissa) in independent transgenic lines (see Supplemental Figure 8 online for enlarged views). Expression levels were estimated by densitometric analysis as for Figure 2C and are expressed in units relative to endogenous phyB. The hypocotyl lengths are presented relative to D. Data are the means ± se (n = 25). WT, the wild type.
