(a) Immunohistochemically GUS assay of the transgenic cotton leaf. (b) PCR amplification of a 690 bp fragment of RMYB gene from transgenic plants, M:1 kb DNA Ladder, lane 1–7 transgenic plants. (c) Transgenic plants in pots under drought, cold, and salt stress. (d) Expression analysis of RMYB gene in transgenic cotton plants under drought, salt, and cold stress. β-Actin gene was used as internal control to normalize data and gene expression is indicated as a fold-increase relative to the control condition.
