Abstract.
The response to fusicoccin (FC) of the elongated tomato mutant procera was tested. Hypocotyl sections from etiolated procera seedlings responded to a range of FC concentrations similar to that of normal sections, but at a given FC concentration the mutant sections exhibited about 40% greater elongation than normal. The initial rates of elongation in FC were similar for normal and procera sections, but elongation continued at a high rate for a longer period in the mutant. Measurements of outer cortical cells demonstrated that the enhanced elongation of the procera hypocotyl sections was due to enhanced cell expansion.
