Integrated metabolome and transcriptome analysis of maize roots response to different degrees of drought stress.

ABSTRACT:

Background

Plants in arid environments can regulate the generation of specialized metabolites to enhance their adaptability. Roots serve as the first defense line, responding directly to drought situations; however, the knowledge regarding the molecular mechanisms of metabolite changes to drought in maize roots remain largely limited. Here, we employed RNA-seq and UPLC-MS/MS methods to examine changes in the root metabolome and transcriptome of maize seedlings subjected to moderate drought (MD) and severe drought (SD) conditions by controlling water supply.

Results

Compared to the untreated control group, 460 differentially accumulated metabolites were detected in roots under MD and SD conditions. Among these metabolites, lignin compounds emerged as the primary response to d
