225a and 225b are R2 progeny from two independent backcrosses of R1 transformants. Data are expressed as mg g−1 extract-free internodes or whole plants and represent the mean of two independent experiments with individual values varying by <3% from the mean. The values reported for the entire plants were obtained from a second set of plant culture.
