Impact of phytohormones regulating photomorphogenesis and photosynthesis at the whole-plant level under optimal growth conditions. A, Hormonal regulation of photomorphogenesis in plants. B, Positive (blue) and negative (red) interactions are represented by arrows or inhibition lines, respectively. A, Indirect and direct hormonal impacts of photosynthesis at the whole-plant level.
