Unfolded protein response (UPR) target genes are upregulated during Tm-induced ER stress. Five-day-old Arabidopsis seedlings were pre-grown in liquid MS medium, then subjected to stress by replacing the media with liquid MS supplemented with designated concentrations of Tm for 3 days. The recovery was performed by incubating stressed seedlings in liquid MS medium for another 3 days. The transcript accumulation of (A) CRT1, (B) CRT3, (C) CNX1, and (D) bZIP60 splicing were measured by real-time PCR and normalized to a housekeeping gene UBQ5. Statistical analysis was performed with Student’s t-test comparing values from Tm-exposed seedlings to regular MS-grown seedlings, *p < 0.05, **p < 0.01, ***p < 0.001. Experiments were performed in at least three independent biological replications. Error bars represent SE between these replications.
