A study integrates metabolomic, transcriptomic, and gene co-expression network analysis confirmed that the key to adaptation to drought by millet was to enhance lignin metabolism, promote the metabolism of fatty acids to be transformed into cutin and wax, and improve ascorbic acid circulation (Cui et al., 2023). These present studies emphasize the potential of metabolomics and proteomics in identifying biochemical markers and understanding the metabolic adjustments in plants under drought stress.
