Integrative Transcriptomic and Metabolomic Insights Into Saline-Alkali Stress Tolerance in Foxtail Millet.

ABSTRACT: Foxtail millet (Setaria italica), a cereal crop in China, is renowned for its resilience to abiotic stresses, including saline-alkali conditions. This study examined the transcriptomic and metabolomic responses of two contrasting foxtail millet varieties, B103 (tolerant) and B323 (sensitive), under saline-alkali stress. Physiological analysis showed that B103 exhibited higher growth parameters and chlorophyll content than B323, highlighting its enhanced tolerance. Transcriptomic analysis identified differentially expressed genes (DEGs) enriched in stress-response pathways such as phenylpropanoid biosynthesis, flavonoid metabolism and calcium signaling. Metabolomic profiling revealed differentially accumulated metabolites (DMs) involved in energy and secondary metabolism, including c
