Fig. 2. MHZ1 expression is induced by ethylene through directly binding of OsEIL1 to its promoter region.

Fig. 2

a MHZ1 expression induced by ethylene is dependent on OsEIN2 and OsEIL1. Two-day-old etiolated seedlings of WT or Osein2 and Oseil1 were treated with 10 ppm ethylene or air. Data are means ± SD, n = 4. b Binding of OsEIL1 protein to the OsEIL1 binding site (EBS) containing region of MHZ1 promoter in vitro. GST-tagged OsEIL1 N-terminus protein was isolated and incubated with biotin-labeled probes carrying EBSs of MHZ1 promoter. An excess of unlabeled probe was added as the competitor. c Transient expression of OsEIL1 in tobacco leaves activated MHZ1 promoter activity. Relative luminescence intensity was calculated, data are means ± SD from three biological replicates. Source data are provided as a Source Data file.
