Figure 2.

Light micrographs showing cross sections of leaf anatomy and chlorenchyma structure of B. sinuspersici plants grown under ML conditions (400 μmol quanta m⁻² s⁻¹) and then transferred to LL (20 μmol quanta m⁻² s⁻¹) for 1 month. Young leaves (0.1–0.3 cm) were divided into two parts, YB (A–C) and YT (D–F). Intermediate-sized leaves (0.5–0.6 cm) were divided into two parts, IB (G–I) and IT (J–L). Cross sections of M leaves (>2 cm) are shown in M to O. PAS staining for polysaccharides showing starch grains is shown in C, F, I, L, and O. Cross sections were taken from the middle of each sample. Abbreviations are as in Figure 1. Bars = 100 μm (left panels) and 10 μm (middle and right panels).
