Downregulation of senescence-related genes by cryptochromes. The mRNA levels of SAG12, YLS4, ORE1, ORS, NAP, ANA046, SGR1, NYC1, ATG7, and ATG18A in the WT and cry1 cry2 fourth leaves before (0 d) and after the pretreatment with 50.0 µmol m⁻² s⁻¹ FR light for 5 min followed by incubation in darkness (Dark) or under 3.0 µmol m⁻² s⁻¹ blue light (Blue) for 3 d. The data are means ± SD (n ≥ 3). Different letters indicate statistically significant differences (P < 0.01, Tukey–Kramer test).
