Network of the transcriptome and metabolomics reveals a novel regulation of drought resistance during germination in wheat.

The DEGs that participated in the mTOR and α-linolenic acid metabolism pathways were considered candidate DEGs related to drought resistance and the key metabolites α-tocotrienol, linoleic acid and l-leucine, which could trigger a comprehensive and systemic effect on drought resistance during germination by activating mTOR-ABA signalling and the interaction of various hormones.
