Expression profiles of ICME and its homologs in response to abiotic stresses and ABA. Seven-day-old seedlings were subjected to different abiotic stresses including cold at 4°C (A), heat at 37°C (B), drought (C), 400 mM mannitol (D), 200 mM NaCl (E), and 50 μM ABA (F) for different time indicated. The transcripts were determined consequently by real-time quantitative RT-PCR, and the relative expression of ICME and its homologs compared to that of Actin8 gene was shown as mean and SD (n = 3).
