De novo transcriptome assembly and characterization of nine tissues of Lonicera japonica to identify potential candidate genes involved in chlorogenic acid, luteolosides, and secoiridoid biosynthesis pathways

ABSTRACT: In this study, we performed de novo transcriptome assembly for L. japonica, representing transcripts from nine different tissues. A total of 22Gbps clean RNA-seq reads from nine tissues of L. japonica were used, resulting in 243,185 unigenes, with 99,938 unigenes annotated based on homology search using blastx against NCBI-nr protein database. Unsupervised principal component analysis and correlation studies using transcripts expression data from all nine tissues of L. japonica showed relationships between tissues explaining their association at different developmental stages. Homologs for all genes associated with chlorogenic acid, luteolin, and secoiridoid biosynthesis pathways were identified in the L. japonica transcriptome assembly. Expression of unigenes associated with chlorogenic acid were enriched in stem and leaf-2, unigenes from luteolin were enriched in stem and flowers, while unigenes from secoiridoid metabolic pathways were enriched in leaf-1 and shoot apex. Our results showed that different tissues of L. japonica are enriched with sets of unigenes associated with a specific pharmaceutically important metabolic pathways, and therefore, possess unique medicinal properties. Present study will serve as a resource for future attempts for functional characterization of enzyme coding genes within key metabolic processes.

De novo Assembly and Characterization of Swertia japonica Transcriptome for the Identification of Candidate Genes Involved in the Biosynthesis of Therapeutic Metabolites

Project description:Here, we performed deep transcriptome sequencing for the aerial-tissues and the roots of S. japonica, generating over 2 billion raw reads with an average length of 101 nt by using an Illumina paired-end sequencing by HiSeq2000 platform. Using a combined approach of three popular assemblers, de novo transcriptome assembly for S. japonica was obtained, yielding in 81,729 unigenes with an average length as 884bps and N50-value as 1,452bps, with 46,963 unigenes being annotated based on the sequence similarity against NCBI-nr protein database.

RNA-seq transcriptome analysis of Panax japonicus, and its comparison with other Panax species to identify potential genes involved in the saponins biosynthesis

Project description:In this study, we have performed Illumina based RNA sequencing to characterize the transcriptome and expression profiles of genes expressed in 5 tissues of P. japonicus. RNA sequencing and de novo transcriptome assembly for P. japonicus resulted in a total of 135,235 unigenes with 78,794 (58.24%) unigenes being annotated using NCBI-nr database. Transcriptome profile and GO enrichment analysis for 5 tissues of P. japonicus showed that although each tissue was characterized by several unique unigenes with leaf showing the most unique unigenes among all, overall processes were evenly conserved across all tissues.

De novo transcriptome assembly and characterization of medicinal plant Lithospermum officinale to discover putative genes involved in specialized metabolites biosynthesis

Project description:In this study, we have performed Illumina based RNA sequencing to characterize the transcriptome and expression profiles of genes expressed in 3 tissues of L. officinale. RNA sequencing and de novo transcriptome assembly of L. officinale resulted in a total of 77,047 unigenes with N50 value as 1524 bps. KEGG pathway and GO enrichment analysis using highly expressed unigenes across three tissues showed active secondary metabolic processes specifically enriched to the root of L. officinale. Expression of identified candidate unigenes for specialized metabolites biosynthesis were consistent with previous reports on accumulation of metabolites across different tissues of L. officinale.

Transcriptional profiling of chickpea genes differentially expressed in response to drought stress using high density oligonucleotide microarray

Project description:Chickpea (Cicer arietinum L.) is an important pulse crop grown mainly in the arid and semi-arid regions. Due to its taxonomic proximity with the model legume Medicago truncatula and its ability to grow in arid soil, chickpea has its unique advantage to understand how plant responds to drought stress. This microarray was used for analyze the transcriptomic profiles of unigenes in leaf and root of chickpea seedling under drought stress, respectively. Microarray data showed that 4805 differentially expressed unigenes were either greater than 2 fold up- or less than 0.5 fold down-regulated in at least one of the 5 time points during drought stress. 2003 and 3488 unigenes were time-dependent differentially expressed in root and leaf, respectively. 110 pathways in two tissues were found to respond to drought stress. Compared to control, 88 and 52 unigenes were expressed only in drought-stressed root and leaf, respectively, while nine genes were expressed in both tissues. 2484 function-unknown unigenes were found to be remarkably regulated by drought stress. The expression profiles of these time-dependent differentially expressed unigenes were useful in furthering our knowledge of the drought tolerance mechanism of plant.

Comparative transcriptome analyses of three medicinal Forsythia species and prediction of candidate genes involved in secondary metabolisms [Forsythia viridissima]

Project description:Here, de novo transcriptome assemblies for leaf and flower tissues of Forsythias were performed, resulting in 81913 unigenes of F. suspensa, 88491 unigenes of F. viridissima and 69458 unigenes of F. koreana (F. viridissima var. koreana). Classification of the annotated unigenes by gene ontology terms and KEGG pathways was used to explore transcriptomic differences among the Forsythias. Orthogroup was introduced to compare expression levels of unigenes in tissues from different species, which unveiled that three leaf tissues of Fosythias were closely correlated based on expression values of orthologous unigenes. Showing high expression mainly in leaves of F. viridissima and F. koreana, candidate homologs for genes involved in the biosynthetic pathway of lignans and phenylethanoid glycosides were determined in these transcriptome assemblies.
