Abstract:

Sucrose is the primary form of photosynthetic products in plants, not only constituting the carbon skeleton of plants, but also the energy source for sink organs. In addition, sucrose could function as a signaling molecule and participates in multiple biological processes. Palatinose, an isomer of sucrose, does not participate in sugar metabolism, but regulates sugar signaling in plants. The utilization of palatinose could overcome the problem of the conversion between hexose and sucrose, and is conducive to studying the perception and transmission pathways of sucrose signals. In this study, Illumina HiSeq platform was used to perform transcriptome and expression profiling on wheat leaves treated with sucrose and palatinose, respectively. Through comparative transcriptome analysis, we identified 4,174 common differentially expressed genes (DEGs). According to bioinformatics analysis including functional annotation and pathway enrichment, these DEGs were divided into four categories, namely signaling (587), plant hormone regulation (121), transcription factor (210) and metabolic pathways (890). These DEGs were most likely related genes of the sucrose signal transduction pathway. This study provides a new insight and theoretical foundation for the enrichment of the sucrose signal transduction pathway and the elucidation of its mechanism of action.
