Figure 1.

The Temporal Expression of the Core Clock Components TOC1 and PRR3 Is Coregulated, and the PRR3 Vasculature Expression Pattern Partially Overlaps with That of TOC1.

(A) and (B) Diurnal time course array data from Diurnal (http://diurnal.cgrb.oregonstate.edu). Relative expression of PRR3 (open circles) and TOC1 (open squares) under long days (LD; 16-h light/8-h dark cycles) (A) and short days (SD; 8 h-light/16-h dark cycles) (B).

(C) and (D) Expression pattern of PRR3 and TOC1. Two-week-old plants were entrained in photocycles (12 h of light/12 h of dark), and GUS activity was detected for PRR3:GUS (C) and TOC1:GUS (D). Bars = 1 mm.
