Transcriptomic and Metabolomic Analyses of the Effects of Exogenous Trehalose on Heat Tolerance in Wheat.

ABSTRACT: Trehalose can improve the tolerance of plants to various types of environmental stress. Nonetheless, information respecting the molecular networks of wheat seedlings to exogenous trehalose under heat stress is limited. Here, two wheat varieties pretreated with exogenous trehalose were selected to explore the molecular mechanism by which trehalose improves the heat tolerance of wheat (Triticum aestivum L.). The results indicated that exogenous trehalose improved the physiological state of wheat seedlings under heat stress. Through RNA sequencing and metabolomics analysis, the genes and metabolites specifically expressed in trehalose pretreatment were identified. After heat stress, there were 18,352 differentially expressed genes (DEGs) in the control and trehalose-treated (H_vs_TreH)
