• This work provides new evidences on the effect of pre-harvest red (R), green (G), blue (B), and white (W – R:G:B; 1:1:1) LED light supplementation on production, nutraceutical quality and Botrytis cinerea control of harvested strawberry fruit. Yield, fruit color, firmness, soluble solid content, titratable acidity, primary and specialized metabolites, expression of targeted genes and mold development were analyzed in fruit from light-supplemented plants, starting from the strawberry flowering, radiating 250 μmol m–2 s–1 of light for five hours per day (from 11:00 to 16:00 h), until the fruit harvest. Briefly, R light induced the highest productivity and targeted anthocyanin accumulation, whilst B and G lights increased the accumulation of primary and secondary metabolites especially belonging to ellagitannin and proanthocyanidin classes. R light also promoted pathogen tolerance in fruit by the upregulation of genes involved in cell wall development (F × aPE41), inhibition of fungus polygalacturonases (F × aPGIP1) and the degradation of B. cinerea beta-glucans (F × aBG2-1). Our dataset highlights the possibility to use red LED light to increase fruit yield, “photomodulate” strawberry fruit quality and increase B. cinerea tolerance. These results can be useful in terms of future reduction of agrochemical inputs through the use of R light, enhancing, at the same time, fruit production and quality. Finally, further analyses might clarify the effect of pre-harvest supplemental G light on postharvest fruit quality. •Pre-harvest LED light supplementation improved strawberry fruit quality and safety.•Red light promoted the highest yield and anthocyanin content.•Red light supplemented fruits counteracted Botrytis cinerea development.•Red light induced an up-regulation of genes encoding plant cell wall enzymes.
