Network of phytohormone signaling regulating photosynthesis under optimal and stress conditions. Color lines connecting phytohormones indicating hormonal crosstalk. Lines with arrowheads present positive (promoting) effects. Blocked lines present negative (inhibitory) effects. Gray dash lines present hormonal interplay. ASR, Arabidopsis stress ripening 1; Aux, auxins; COP1, CONSTITUTIVE PHOTOMORPHOGENIC1; DS, drought stress; ET, ethylene; FPS, fruit photosynthesis; HY5, elongated hypocotyl 5; LS, excess light stress; PIF, PHYTOCHROME INTERACTING FACTOR; PM, photomorphogenesis; PS, photosynthesis; SIGs, sigma factor genes; VDE, violaxanthin de-epoxidase.
