摘要

Light-emitting diodes (LEDs) have been widely used in plant factories and agricultural facilities. Different LEDs can be designed in accordance with the light quality and intensity requirements of different plants, allowing the regulation of plant growth and development, as well as metabolic processes. Blue and red lights have significant effects on anthocyanin metabolism in strawberry fruit, but their effects on other metabolites are unknown. Here, we studied the effects of blue and red lights on the metabolism and gene expression of strawberry using metabolomics combined with transcriptomics. A total of 33 differentially expressed metabolites (DEMs) and 501 differentially expressed genes (DEGs) were isolated and identified. Among these DEMs, chlorogenic acid synthesis was upregulated by the blue light compared with the red light. Co-expression network analysis of DEMs and DEGs revealed that the expression of hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyltransferase (FvHCT), the main gene in the chlorogenic acid synthetic pathway, was induced by blue light. Using multi-omics-based approach, our results suggest that different LED lights have multiple effects on strawberry fruit, with blue light able to co-upregulate chlorogenic acid synthesis and FvHCT gene expression.
