Overexpression of BRM in mms21-1 partially rescues its root developmental defect. A, The root length for 5-d-old seedlings of wild type (WT), mms21-1, 35S:BRM in mms21 (two independent lines), and 35S:BRM in wild type (two independent lines). The photo is a representative from three independent experiments. Bar = 1 cm. B, The meristem regions for 5-d-old roots of the indicated seedlings stained by PI. The meristem region is indicated by arrowheads; quiescent center is indicated by the lower arrowhead. Bar = 100 µm. C, The statistical data of root length and meristem cell number for 5-d-old seedlings. The data for root length are means ± sd from at least 30 seedlings in an experiment. Three biological independent experiments displayed a similar pattern. The meristem cell number (n = 15) are from at least three independent experiments. ***P < 0.001, Student’s t test.
