AML insertion mutants bolt early. A. Wassilijewskia (Ws) and AML1 insertion homozygotes (AML1-/-) grown under long days. B. Bolting time and number of rosette leaves at time of bolting for AML single insertion and higher order insertion mutants. Plants were grown under 16 hour days. Ws and Columbia (Col 0) ecotypes are the two points in the top left of the graph; the cluster of points at the lower right are all AML-/- mutants.
