Transcriptome and metabolite profiles reveal differential molecular responses of wild and cultivated amaranth species to water deficit and salt stress

Key Points

• Differential molecular responses to water deficit and salt stress are observed in wild versus cultivated amaranth species.
• Cultivated amaranth showed altered transcriptome and metabolite profiles compared to its wild counterparts under stress conditions.
• Assessment of transcriptome and metabolite profiles during both water deficit and salt stress highlighted unique adaptations in each species.
• These findings suggest that wild species may possess superior stress resistance, which could inform agricultural practices for water-scarce environments.
