Outline
In order to investigate the sugar transport pathway involved in wheat TaSTP3 gene and its role in wheat-stripe rust interactions, TaSTP3-RNAi transgenic wheat T2 generation plants and Fielder wheat plants were used for RNA-seq, to screen for differentially expressed genes (DEGs) and to use GO and KEGG analyses to speculate on the possible involvement of the TaSTP3 gene in the regulatory pathway and the number of genes involved. The results showed that there were 7 660 DEGs, of which 3 194 were up-regulated and 4 466 were down-regulated. GO functional enrichment revealed that the DEGs were mainly concentrated in the metabolism and synthesis of sugars, carbohydrates, and cellulose; KEGG enrichment analysis showed that the expression of genes in the metabolism and synthesis of sugars, amino acids and lipids changed significantly after TaSTP3 gene silencing, and more genes were enriched in the phytohormone signaling and phenylpropanoid biosynthesis pathways. In summary, it is hypothesized that TaSTP3 alters the distribution of sugars in stripe rust-wheat intercropping by transporting sugars, and in this way transmits molecular signals to affect the metabolism of other nutrients, phytohormone transduction, and photosynthesis, so that target genes interacting with TaSTP3 can be searched from the above pathways, and their involvement in the regulatory pathways can be verified.
