| Zusammenfassung: | © The Author(s) 2025. Published by Oxford University Press on behalf of the Society for Experimental Biology. The introduction of LED light in plant research and controlled environment agriculture has given a boost to understanding how light regulates tomato physiology. This paper reviews the regulation of whole-plant physiological processes in tomato by light. Emphasis is on morphogenesis, light interception, photosynthesis, source/sink interactions, assimilate partitioning, fruit set, fruit development, plant-water relations and how this controls plant growth and fruit quality. Five key aspects of light determine the ultimate plant response, i.e. intensity, photoperiod, spectrum, directionality, and energy. Tomato possesses five phytochromes, four cryptochromes, two phototropins, one zeitlupe, and one UV-B photoreceptor. Via spectral sensing and photosynthesis, light affects plant morphology, which in turn affects the light interception and consequently whole-plant carbon assimilation. Photosynthesis and carbon partitioning are dynamic processes affected by light. Furthermore, light plays a pivotal role in regulating plant-water-nutrient dynamics by influencing transpiration, stomatal conductance, hydraulic conductance, and cell wall properties. Changes in light intensity and spectrum may also increase contents of ascorbate, carotenoids, sugars and volatiles improving fruit quality. The complex physiological responses of tomato plants to the five aspects of light and their interaction, render endless opportunities for future scientific research with the aim of improving light-use efficiency, yield, and quality |
