Fig 1. The root of sr5 mutant growth is restricted and its root meristem size is reduced.

Fig 1

(A) The phenotype of five-day old WT and sr5 seedlings. Bar = 1 cm. (B) Primary root growth over the first ten days following germination. Data shown are mean±SE (n = 25). (C) Longitudinal zonation pattern in the primary roots of five-day old WT and sr5 seedlings. Cell boundaries appear red following Propidium Iodide staining. The meristem zone (MZ) and transition zone (TZ), which together form the root apical meristem (RAM), and the elongation zone (EZ) are indicated. Bar = 50 μm. (D) Root cortical cell length in the maturation zone of five-day old WT and sr5 seedlings. Data shown are mean±SE (n = 100), **: means of sr5 and WT differ significantly (P<0.01). (E) Cell number in the proliferation domain of five-day old WT and sr5 seedlings. Data shown are mean±SE (n = 25), **: means of sr5 and WT differ significantly (P<0.01). (F) pCYCB1;1::GUS expression in root tips of five-day old WT and sr5 seedlings. Bar = 50 μm.
