Continuous light on tomato. From Gene to Yield

Light essentially sustains all life on planet earth surface. Plants transform light energy into chemical energy through photosynthesis. Hence, it can be anticipated that extending the daily photoperiod, using artificial light, results in increased plant productivity.

Although this premise is true for many plant species, a limit exists. Since the 1920’s, for instance, it is known that tomato plants develop leaf injuries if exposed to continuous light. Many studies have investigated the physiological mechanism inducing such CL-induced injury. Although important and valuable discoveries were done over the decades, by the time the present project started in 2007, a detailed and proven physiological explanation of this disorder was still missing. Here, I present the results of my PhD project that aimed to better understand the physiological basis of the continuous-light-induced injury in tomato and develop the tools (genetic and conceptual) to cultivate tomatoes under continuous light.
