Figure 3.

Leaf morphology and ploidy levels of sun and shade leaves in the bin4 mutant. bin4 mutant plants were grown under low light (LL) conditions (a–d) and high light (HL) conditions (a′–d′) for 21 days after sowing (DAS) on either rockwool (a, c, a′, c′) or MS plates with 2% sucrose (+sucrose; b, d, b′, d′). (a, a′, b, b′) Ploidy profiles of leaf blades grown under LL (a, b) and HL (a′, b′) conditions. Samples included more than 10 foliage leaves. (c, c′, d, d′) Transverse sections (upper) and paradermal view (lower) of the fourth foliage leaves. Typical palisade cells are outlined at each stage. Representative data from more than three replicates are shown. Scale bars: 50 μm.
