Integrated transcriptome and metabolome analysis revealed differential drought stress response mechanisms of wheat seedlings with varying drought tolerance.

ABSTRACT:

Background

Wheat (Triticum aestivum L.) is a staple crop frequently enduring drought stress, significantly impacting its quantity and quality. Therefore, elucidating the underlying mechanisms of wheat's drought stress response is crucial for developing drought-tolerant varieties through molecular breeding techniques.

Results

This study analyzed the transcriptome and metabolome of wheat seedlings with varying drought tolerance (drought-tolerant T13, control CK, and drought-susceptible T2) under drought stress. Results suggested that T13 and T2 had partially similar drought stress response mechanisms. But the mainly drought response mechanisms in T13 (accumulated flavonoids and phenolic acids) was different from T2 (accumulated alkaloids). Integrated metabolome and transcripto
