Phytohormone Transcript Abundance Correlates with Time of Hypocotyl Growth under Short-Day Photocycles and Continuous Light
(A) Phytohormone genes display peak transcript overrepresentation during the phase of peak growth. Peak growth rate under short-day photocycles (black dashed lines) and continuous light (red dashed lines) reproduced from [15–17] correlates with peak transcript overrepresentation under short-day photocycles (black bars) and continuous light (red bars).
(B) _Z_-score significance score for individual groups of phytohormone genes under short day. Data generated using PHASER. _Z_-score = 3, approximately p = 0.01. GA (dashed brown), ACC (red), CK (blue), BR (orange), IAA (green), and ABA (black).
(C) Phytohormone biosynthesis transcripts show peak abundance during the growth phase under short-day photocycles.
(D) Phytohormone signaling transcripts show peak abundance during the growth phase under short-day photocycles.
Data in (A) and (B) are double plotted for visualization purposes; 1 d (24 h) of data copied and graphed a second day to allow visual continuity of the time-of-day data. Gene names in (C) and (D) are indicated, and the phytohormone pathway is in parentheses.
