Genome-Wide Investigation and Expression Profiling of HD-Zip Transcription Factors in Foxtail Millet (Setaria italica L.)

Figure 6

Expression profiles of 13 selected HD-Zip I genes under drought, salinity, and ABA stresses using qRT-PCR. (a) The expression profiles under PEG treatment. (b) The expression profiles under NaCl treatment. (c) The expression profiles under ABA treatment. The expression of each gene was calculated as a ratio relative to its expression in the control sample (0 h). Actin was used as an internal control to normalize the data.
