Frequency of leafless dome formation in response to NPA. A, Wild-type Columbia, wild-type Enkheim, pin1(Enk) segregating population, pid segregating population, Pro35S:MP, and mp plants were grown on a series of medium containing 0 to 100 μm NPA. All genotypes were scored at 35 DAG and leafless dome formation was judged by the presence of leafless dome structure. Between 42 and 178 plants were scored for each genotype and treatment. B, Wild-type Columbia (gray bars) and mp (white bars) plants were grown on medium as in A and were scored for number of leaf primordia visible under a dissecting microscope at 21 DAG. **, Significant difference between NPA-grown wild type and mp mutants within the respective NPA treatment as determined by Student's t test analysis; P < 0.05. Error bars = sd.
