Cold-Tolerant Chrysanthemum Sugar Pathway

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.

Advantages

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
