Hormones are effective in regulating plant metabolism and, therefore, are often used in plant cell culture to increase the yield of target products. This study investigated the effects of hormones on the growth and anthocyanin biosynthesis of suspension‐cultured red Cyclocarya paliurus cells. Additionally, the mechanism by which gibberellin induces anthocyanin biosynthesis was explored through multi‐omics integrated analysis and the assay of the dynamic changes in signaling molecule concentration. The results showed that the total anthocyanin content and yield of suspension‐cultured cells, when induced by 1.0 mg L⁻¹ Gibberellin A3 (GA3), experienced increases of 1.92‐ and 1.83‐fold, respectively. The application of exogenous GA3 activated the synthesis and transduction of four signaling molecules, that is, nitric oxide (NO), hydrogen peroxide (H2O2), salicylic acid (SA), and jasmonic acid (JA), in the cells and altered the expression patterns of transcription factors. The altered expression of transcription factors upregulated the expression of anthocyanin biosynthetic genes such as anthocyanin‐3‐O‐glucosyl transferase and leucoanthocyanidin dioxygenase, while downregulated the expression of anthocyanin reductase and flavonoid 3′,5′,‐hydroxylase, which activated the anthocyanin biosynthesis pathway, ultimately leading to a significant increase in anthocyanin biosynthesis. This research work establishes a foundation for further research on the role of hormones in regulating anthocyanin biosynthesis in suspension‐cultured plant cells.

Wheat is the most widely grown crop in the world; its production is severely disrupted by increasing water deficit. Plant roots play a crucial role in the uptake of water and perception and transduction of water deficit signals. In the past decade, the mechanisms of drought tolerance have been frequently reported; however, the transcriptome and metabolome regulatory network of root responses to water stress has not been fully understood in wheat. In this study, the global transcriptomic and metabolomics profiles were employed to investigate the mechanisms of roots responding to water stresses using the drought-tolerant (DT) and drought-susceptible (DS) wheat genotypes. The results showed that compared with the control group, wheat roots exposed to polyethylene glycol (PEG) had 25941 differentially expressed genes (DEGs) and more upregulated genes were found in DT (8610) than DS (7141). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the DEGs of the drought-tolerant genotype were preferably enriched in the flavonoid biosynthetic process, anthocyanin biosynthesis and suberin biosynthesis. The integrated analysis of the transcriptome and metabolome showed that in DT, the KEGG pathways, including flavonoid biosynthesis and arginine and proline metabolism, were shared by differentially accumulated metabolites (DAMs) and DEGs at 6 h after treatment (HAT) and pathways including alanine, aspartate, glutamate metabolism and carbon metabolism were shared at 48 HAT, while in DS, the KEGG pathways shared by DAMs and DEGs only included arginine and proline metabolism at 6 HAT and the biosynthesis of amino acids at 48 HAT. Our results suggest that the drought-tolerant genotype may relieve the drought stress by producing more ROS scavengers, osmoprotectants, energy and larger roots. Interestingly, hormone signaling plays an important role in promoting the development of larger roots and a higher capability to absorb and transport water in drought-tolerant genotypes.
