“… Zheng et al (2017) confirmed that QUA1, which has been identified as a glycosyltransferase in Arabidopsis , increases drought tolerance by regulating chloroplast-associated calcium signaling. Similar findings have also been shown in rice ( Oryza sativa L.; Dinesh et al, 2017 ). The following pathways involved in carbohydrate metabolism were found to be down-regulated in our KEGG-based metabonomics analyses despite high FDR values: fructose and mannose metabolism, glyoxylate and dicarboxylate metabolism, pyruvate metabolism, glycolysis/gluconeogenesis, pentose phosphate pathway, and starch and sucrose metabolism.…”

The response of okra to drought stress is very complicated, and the molecular mechanisms underlying this process remains ambiguous up to now. In this study, different degrees of water-stress responses of okra leaf were explained by using transcriptomics and metabolomic approaches. The photosynthesis and glycometabolism in okra leaf were both adversely affected by drought stress, leading to inhibition of the carbohydrate metabolic process, and then influencing the secondary plant metabolism. Further, drought stress disturbed amino acid metabolism, especially for the tyrosine-derived pathway as well as arginine and proline metabolism, which have been shown to be significantly enriched under water withholding conditions based on multi-omics conjoint analysis (transcriptome, proteome and metabolome). In-depth analysis of the internal linkages between differentially expressed transcripts, proteins, and metabolites decidedly indicate that tyrosine metabolism could confer tolerance to drought stress by influencing carbon and nitrogen metabolism. These findings provide a whole framework of the regulation and relationships of major transcripts and peptides related to secondary metabolism, particularly, the role of critical proteins and metabolite involved in the change of amino acid metabolism in response to drought stress.
