Stomatal development on gynoecial valves in response to reduced <i>AG</i> and <i>SHP</i> activity.

(A-F) Scanning electron micrographs of (A-C) stage 12 and (D-F) stage 13 L-er, ag-10, and ag-10 shp1 shp2 gynoecia, as indicated. Purple, blue, and red highlights indicate early, mid, and late-stage stomatal lineage morphology, respectively. (G-H) Scanning electron micrographs of a (G) ful-1 and (H) ag-10 ful-1 silique. Asterisks indicate presence of stomata. Scale bars for images of whole gynoecia are 100 μm. Scale bars for magnifications are 20 μm. (I-J) Index of early, mid, and late stomatal lineages based on morphological and cell size analysis of scanning electron micrographs from (I) stage 12 and (J) stage 13 L-er, shp1 shp2, ag-10, ag-10 shp1 shp2 gynoecia. Each dot represents an individual sample.
