Growth Spectrum Complexity Dictates Aromatic Intensity in Coriander (Coriandrum sativum L.)

“…In contrast, photoreceptors determine plant structure and morphology and can operate within and outside of the PPFD region-for example, phototropins perceive both blue (400-500 nm) and UV-A (315-400 nm) wavelengths-mediating processes such as phototropism (Briggs and Christie, 2002;Fraser et al, 2016). Three major photoreceptors regulate the development and growth of the plant dependent on the perception of the environment; the phytochromes, cryptochromes, and phototropins (Larner et al, 2008). These receptors respond to red:far-red ratio and blue wavelengths, respectively.…”

Cryptochromes and the Circadian Clock: The Story of a Very Complex Relationship in a Spinning World

“…During the day, all organisms are exposed to dial environmental rhythms: The daily transition from light to dark and the daily fluctuation of temperature. Specific light and temperature sensors enable the organisms to sense and respond to these changes, maintaining homeostatic balance [ 22 ]. In order to anticipate daily changes, several organisms have developed an internal timing mechanism known as the “circadian clock” that allows them to anticipate and align internal biological processes with these daily rhythms [ 23 , 24 ].…”
