Abstract:

Sucrose is not only the main photosynthetic product and energy substance in plants, but also an important signaling molecule that regulates plant growth and development. Because sucrose in plants is easily hydrolyzed into glucose and fructose, whose signal transduction pathways are not completely the same as those of sucrose. In this study, Illumina high-throughput sequencing platform was used to perform transcriptome and expression profile sequencing in wheat leaves treated with sucrose, glucose and fructose, respectively. A total of 1327 (711 up-regulated and 616 down-regulated) differentially expressed genes (DEGs) that specifically responded to sucrose were screened by comparative transcriptome analysis. Based on functional annotation and pathway enrichment analysis, these differentially expressed genes were divided into four major categories, namely, transcription factors, plant hormone-related, signal-related and metabolism related. Four of the differentially expressed genes belong to three categories (transcription factors, phytohormone-related, and signal-related), and 16 of them belong to two categories: signal transduction and phytohormone. These differentially expressed genes are relevant genes independent of glucose and fructose signaling pathways, and participate in sucrose-specific signal transduction pathways. At the same time, the conclusion of this research will provide a theoretical basis for the improvement of sucrose signal transduction pathways and the illustration of their mechanism of action.
