Cold-induced osmolyte buildup
Integrative metabolomics and transcriptomics reveal that chrysanthemum enhances cold tolerance by accumulating osmolytes such as sucrose, trehalose, and raffinose, providing molecular targets for breeding cold-resistant cultivars.

Among 1,371 detected metabolites, 21 sugar-related DAMs significantly responded to low temperature
Sucrose, trehalose, and raffinose accumulated significantly under low temperature
WGCNA identified red and tan modules significantly correlated with sugar metabolism
Starch and sucrose metabolism is the central pathway in cold response
