LIGHT5/TZP controls morning-specific growth pathways. (A) TZP displays dawn-specific transcript abundance under light/dark cycles (12 hours/12 hours) and constant 22 °C (six time points). The second day of data are copied from the first (double plotted) for visualization purposes. Expression was determined by qPCR with primers specific to TZP and SyberGreen. (B) TZP transcript abundance is overexpressed in TZP-OX. Five independent lines overexpressing TZP were characterized. Two lines are shown here. Data were collected and plotted as in (A). (C) The genes that are misexpressed (P < 0.01) in long hypocotyl genotypes (TZP-OX or rHIF138-13 vs. rHIF138-8) under blue light short day photocycles are expressed at dawn as determined with PHASER. (D) Long hypocotyls of the TZP-OX mutant are due in part to overexpression of cell wall genes. As an example of the expression pattern of the cell wall genes that are overexpressed in the TZP-OX mutant, IRX1 continues to cycle with peak expression at dawn, but its peak expression is 3-fold higher in TZP-OX (www.inra.fr/vast/Files/Loudet_PNAS_SITables.xls). Results are from array data.
