resemble wild-type plants that have been repeatedly treated with G.A.; long hypocotyls, erect rosette leaves, light green color, early flowering and parthenocarpy; seedlings defective in cotyledon number and phyllotaxy; stem elongation is increased caused primarily by an increase in the number of nodes; completely male sterile grown at 25C, partially sterile at 18C; ovaries often develop 3 or 4 carpels which contain structures appearing to develop from unfertilized ovules that may be additional carpels with stigmatic papillae; altered gibberellin signal transduction, resistant to the giberellin (G.A.) biosynthesis inhibitor paclobutrazol.
