De novo assembly and Transcriptome Analysis of the Momordica charantia Seedlings Responding to methyl jasmonate using 454 pyrosequencing
Momordica charantia, a medicinal and edible species of the Cucurbitaceae family, has been widely used as a vegetable around the world. Hundreds of pharmacological compounds isolated from the M. charantia have been reported. However, the mechanism of action of the secondary metabolites has not been fully elucidated. In this study, 118,590 unigenes were gained by de novo assembly based on the raw data from high-throughput sequencing of mRNA (RNA-Sequencing) upon systemic analysis, among which, 51,860 (43.73%) could be annotated to the public sequence databases such as Nr, GO, Swiss-Prot, KEGG and KOG. The transcriptomic changes of M. charantia seedlings treated with or without methyl jasmonate (MeJA) were analyzed to identify key genes involved in MeJA treatment. Additionally, 554 differentially expressed genes (DEGs), including 328 up-regulated ones and 226 down-regulated genes, have been identified. Most DEGs were associated with secondary metabolism and stress responses. Meanwhile, six DEGs were further confirmed by quantitative real-time RT-PCR (qRT-PCR) analysis, resulting in similar expression patterns as compared to those of RNA-Sequencing. Nine significantly enriched pathways including 11 DEGs were identified to be possibly involved in the MeJA-responsive biosynthesis of secondary metabolites based on the transcriptome sequencing analysis. Among them, 4 DEGs, encoding two peroxidases, one cinnamyl alcohol dehydrogenase and one hypothetical protein Csa, might play important roles in the process of phenylpropanoid biosynthesis. In addition, 9 transcription factors (TFs) were also detected as DEGs from 1899 unigenes. Most of them up-regulated by MeJA treatment might be potentially involved in regulating secondary metabolites biosynthesis. This work is the first research on the large-scale assessment of M. charantia transcriptomic resources and the analysis of DEGs and TFs in secondary metabolites biosynthesis of M. charantia seedings treated with or without MeJA, which will be conducive to the further applications of M. charantia.
期刊介绍:
Gene Expression Patterns is devoted to the rapid publication of high quality studies of gene expression in development. Studies using cell culture are also suitable if clearly relevant to development, e.g., analysis of key regulatory genes or of gene sets in the maintenance or differentiation of stem cells. Key areas of interest include:
-In-situ studies such as expression patterns of important or interesting genes at all levels, including transcription and protein expression
-Temporal studies of large gene sets during development
-Transgenic studies to study cell lineage in tissue formation
