Figure 6

PLL::GUS expression in hydathodes and stipules. (A) GUS activity in hydathodes. In the upper row, 5-d-old seedlings with fully expanded cotyledons are shown. In the lower row, the distal tips of the first rosette leaf on 8-d-old seedlings are shown. The position of the hydathode (h) is indicated for the PLL1 panels. (B) GUS activity in the stipules of an expanding leaf of 6-d-old seedlings. (C) GUS activity in stipules of PLL19::GUS plants at various stages of plant and leaf development: (i) expanding ~3 mm leaf of 6-d-old seedling; (ii) expanding ~6 mm leaf of 6-d-old seedling; (iii) nearly fully expanded leaf (~12 mm) of 8-d-old seedling; (iv) apex of 15-d-old plant showing staining in stipules of primordial cauline leaves; (v) flowering plant showing staining in the stipules of fully expanded cauline leaves
