AtMMS21 Interferes with the Function of the E2Fa/DPa Complex in Plants.

(A) The phenotypes of the wild type, 35S: E2Fa-DPa, and three independent lines (#1, #2, and #3) from verified 35S:DPa-E2Fa-AtMMS21 plants. The photograph was taken 7 d after germination. Bar = 1 cm.

(B) Statistical data for root lengths of the indicated plants. The results are means ± sd from at least 35 seedlings per line at 7 DAG in three independent experiments. ***P < 0.001, Student’s t test.

(C) The phenotypes of 3-week-old seedlings.

(D) The endoreplication levels in the indicated plants were quantitatively analyzed by flow cytometry. The cotyledons of 8-d-old seedlings were used for analysis. The results are means ± sd from of at least three biological replicates.

(E) The relative expression levels of E2Fa target genes in the indicated plants were analyzed by real-time PCR. The expression level in the wild type was set to 1. The data are means ± sd from triplicate experiments. **P < 0.01, ***P < 0.001, Student’s t test.

(F) The effect of mutated AtMMS21 on the function of E2Fa/DPa. The root length of two independent lines (#1 and #2) of 35S:E2Fa-DPa-AtMMS21mut was compared with that of the wild type, 35S:E2Fa-DPa, or 35S:E2Fa-DPa-AtMMS21. The photograph was taken at 7 d after germination, and the statistical data are means ± sd from at least 20 seedlings. ***P < 0.001, Student’s t test. Bar = 1 cm.
