Tomato plants were grown under a daily light cycle of 16h light/8h darkness (LD) and leaves from both genotypes were sampled at presumptive dawn (Zeitgeber time (ZT) 0), eight hours after dawn (ZT8), at presumptive dusk (ZT16) and four hours after dusk (ZT20).

In order to sense and respond to the fluctuating light conditions, higher plants possess several families of photoreceptors, such as phytochromes (PHYs), cryptochromes (CRYs) and phototropins. CRYs are responsible for photomorphogenesis and play a role in circadian, developmental and adaptive growth regulation of plants. In tomato (Solanum lycopersicum), CRY2 controls vegetative development, flowering time, fruit antioxidant content as well as the diurnal transcription of several other photorece ...[more]
