From: Developmentally distinct activities of the exocyst enable rapid cell elongation and determine meristem size during primary root growth in Arabidopsis

Figure 3

Meristems are shorter in exocyst mutants. pCYCB:GUS expression is a marker for cell division activity, and the size of the meristematic zone is designated by the span (arrows) over which GUS staining is detected, in wild-type (A), exo70A1 (B), and sec8-3 (C) root tips. Bar = 50 microns. (D) Average root meristem lengths measured by CYCB:GUS are significantly shorter in exo70A1 (p < 0.01, t-test, n = 30) and sec8-3 (p < 0.001, t-test, n = 19) mutants compared to wild-type siblings (n = 30).
