Key Points

To investigate how exogenous abscisic acid (ABA) affects grain weight in foxtail millet during drought stress.
Measured grain filling rate and weight across different treatments at three growth stages.
Performed transcriptome sequencing and weighted gene co-expression network analysis (WGCNA).
Identified differentially expressed genes (DEGs) and potential transcription factor regulators.
Drought stress reduced grain weight by 12.45% to 23.84% compared to control.
Exogenous ABA application significantly increased grain-filling rate and grain weight in the T3 treatment.
WGCNA revealed ten co-expression modules, with blue and magenta modules positively correlating with grain weight.
