GUS and GFP reporter gene expression under the control of the CRC gene promoter. (A) GUS staining in the gynoecium and nectaries (ne) of a flower from a proCRC::GUS transformant at developmental stage 11–12 (Smyth et al., 1990), showing the expected CRC-like pattern of reporter gene expression. (B) GFP localization in the gynoecium of a flower from a proCRC::GFP transformant at developmental stage 10–11 (Smyth et al., 1990), showing the expected CRC-like pattern of reporter gene expression. (C) GUS staining in leaf tissue of a proCRC::GUS transformant showing reporter gene activity outside of the normal zone of CRC expression. (D) GUS staining in mature flower tissues (se = sepal, st = stamen) in a proCRC::GUS transformant showing reporter gene activity outside of the normal zone of CRC expression.
