Project description:Potato, S. tuberosum, is one of the most important global crops, but has high levels of waste due to tuber greening under light, which is associated with the accumulation of neurotoxic glycoalkaloids. Here, we have investigated the effect of monochromatic far-red, red, and blue light on the regulation of chlorophyll and glycoalkaloid accumulation in tubers of a commercial variety, King Edward. Transcriptomic analysis of tubers exposed to red, blue, and white light showed that light induction of photosynthesis and tetrapyrrole-related genes grouped into two distinct patterns with one group showing much stronger induction in blue at 6 h and 24 h and a second group showing only red induction at 24 h.
