From: Promotion of chloroplast proliferation upon enhanced post-mitotic cell expansion in leaves
Promotion of chloroplast proliferation in response to the enhanced post-mitotic cell expansion in an3 . (A) Area of mitotic subepidermal palisade cells of WT, xs1, an3-4 and xs1 an3-4 leaf primordia. Leaf primordia samples are from 5-day-old plants. The means ± SD from eight individual leaf primordia are indicated. (B) Cell area and chloroplast number per cell measured in subepidermal palisade cells of WT, xs1, an3-4 and xs1 an3-4 leaves. Leaf samples are from 21-day-old plants. The means ± SD of WT, xs1, an3-4 and xs1 an3-4 lines are indicated. Asterisk indicates significant difference at P < 0.01 between the two genotypes (WT versus xs1; an3-4 versus xs1 an3-4) (Student’s t-test).
