Effect of nuclear ploidy on chloroplast proliferation in the leaves of compensation-exhibiting lines. (A and B) Nuclear ploidy in diploid (A) and tetraploid (B) WT, fugu5-1, an3-4 and KRP2 OE lines analyzed through flowcytometoric analysis. Leaf samples are from 21-day-old plants. (C) Cell area and chloroplast number per cell measured in subepidermal palisade cells of WT, fugu5-1, an3-4 and KRP2 OE (diploid and tetraploid) leaves. di, diploid; tetra, tetraploid. Leaf samples are from 21-day-old plants. The means ± SD of WT, fugu5-1, an3-4 and KRP2 OE lines are indicated. Arrows indicate the difference between adjacent bars.
