Fig. 1: Arabidopsis seedlings exhibit a shade avoidance memory in indicated light condition.

a New growth and growth rates and of 6-day-old Col-0 seedlings treated with shade (SH) white light (WL). New growth and real-time growth rate were recorded at 15-min intervals. Shade triggered growth rates of Col-0 seedlings grown under naïve (N) and 2 (b), 4 (c), 8 (d) or 10 (e) h shade-primed (P) conditions. The top panel is real-time growth rates recorded at 15-min intervals for 8 h captured by DynaPlant system. The bottom panel is average growth rates calculated from new growth in four-time spans: I (0–0.75 h), II (0.75–1.75 h), III (1.75–3 h), IV (3–8 h). Data are presented as mean values +/− SEM. Student’s two-sided t-test was used to calculate the P value between the indicated spans, and significant differences are shown by *(P < 0.05), ***(P < 0.001) and ns (P > 0.05).
