The spatial distribution of phytochrome (PHY1) mRNA in the fern Adiantum was investigated by in situ hybridization. PHY1 mRNAs are expressed predominantly in the abaxial rather than the adaxial part of the petiole of leaf croziers. Moreover, the signals in light-grown croziers are predominantly nuclear in location rather than cyto-plasmic.
