FIGURE 6

Drought‐specific configuration of the photosynthetic machinery acquired by wheat in Drought Phase IV. The figure shows changes in single proteins or protein complexes amount, relative to well‐watered condition. There are two special cases: i) light‐harvesting complex II (LHCII), which is shown in two pools, one bound to PSII, one to PSI; ii) decrease of PSII/PSI ratio is depicted as a relative change of PSII and PSI. Circles position does not represent the precise protein/complex localization. CaS, calcium‐sensing protein; Cyt b6f, cytochrome b6f; Fd, ferredoxin; FNR, Ferredoxin‐NADP reductase; FTSH, FtsH protease; HCF136, Photosystem II stability/assembly factor HCF136; LHCI, light‐harvesting complex I; LHCII, light‐harvesting complex II; NDHO, NAD(P)H:plastoquinone dehydrogenase complex subunit O; PC, plastocyanin; PGRL1, PGR5‐like protein 1; PSI, photosystem I; PSII, photosystem II; Rbc, Rubisco; RCA, Rubisco activase; VDE, violaxanthin de‐epoxidase; ZEP, zeaxanthin epoxidase. Comments summarize the drought‐induced functional modifications. LEF, linear electron flow; CEF, cyclic electron flow [Colour figure can be viewed at wileyonlinelibrary.com]
