Elucidation of efficient photosynthesis in plants with limited iron

Figures & data

Figure 1. Model of the thylakoid membrane showing the PSII-LHCII complex, and the putative location of protein complexes. In addition to S-LHCII and M-LHCII, L-LHCII (loosely bound LHCII), which is not bound to the PSII reaction center, forms a large pool of LHCII trimer. Protein complexes indicated in red bind Fe to transfer electrons. Modified from Rantala, Rantala, and Aro (2020), Pan et al. (2020), and Cao et al. (2018) .

Figure 2. Arrangement of LHCII containing Lhcb1 and acclimation to stress. Modified from Rantala, Rantala, and Aro (2020), Yokono and Akimoto (2018), and Xu, Chen, and Chen (2015).

Figure 3. Grana stack in Fe-sufficient and -deficient leaves. We used barley, Ehimehadaka 1. The left panel shows a typical grana stack in Fe-sufficient leaves. The right panel shows a swollen grana-like structure in severely chlorotic leaves.
