FIGURE 6.

Histochemical assay for GUS activity in transgenic plants with the pSUH1::GUS construct. Representative images of Col‐0 (a–e) and ctl1 ^hot2‐1 (f–g) plants from 15 lines with three replicates. (a,f) The embryos are from mature seeds. (b,g) Ten‐day‐old seedlings grown in the light. (c,h) Five‐day‐old seedlings grown in the dark. (d, i) Hand‐cut sections of inflorescence stem of 6‐week‐old plants. (e,j) Flowers of 6‐week‐old plants. Scale bars, 200 μm (a, b, c, f, g, and h) and 5 mm (d, e, i, and j).
