Abstract
- To study the genes regulating the synthesis of sugar esters in tobacco, transcriptome sequencing analysis was performed on tobacco glandular hair cells and bundle sheath cells, and RT-qPCR was used for verification. The results showed that 11 962 differentially expressed genes were obtained, of which 5145 were up-regulated and 6817 were down-regulated. GO annotation of differentially expressed genes showed that the up-regulated genes mainly included biological processes (2265), molecular functions (1169), and cellular components (363), with a total of 3793 GO terms. Based on the assignment of KEGG pathway, the sequence was mapped to 122 metabolic pathways. Glycolysis/gluconeogenesis, starch and sucrose metabolism, phenylpropanoid biosynthesis related to glycoester synthesis were highly enriched, and acyl sugar pathway in glandular hairs was significantly up-regulated. By comparing with the tobacco reference genome, 12 up-regulated acyltransferase genes were identified in glandular hair cells. RT-qPCR results showed that the expression of 11 genes was higher than that of the control. The expression of gene 63826, gene 16194 and gene 37511 increased by 195.79 times, 166.23 times and 132.65 times, respectively. The above 11 genes may be involved in regulating the synthesis of sugar esters in glandular hair cells, providing a basis for further verification of gene function. [ABSTRACT FROM AUTHOR]
