One phytochrome, phyA, na di main phytochrome for seedlings wey dey grow for darkness but e dey quickly degrade for light to produce Cry1. Phytochromes B–E dey more stable with phyB, wey be di main phytochrome for seedlings wey dey grow for light. The cryptochrome (cry) gene too dey sensitive to light and e dey part of di circadian clock wey dey help regulate time. Cryptochromes 1–2 (wey dey involved in blue–UVA) dey help maintain di period length for di clock through different light conditions.
