Transcriptome analysis of Gerbera delavayi based on high-throughput sequencing technology

ABSTRACT: Gerbera delavayi Franch. endemic to southwest China, is a rare fiber plant. In this study, the leaves of G. delavayi were sequenced based on Illumina Hi-Seq2500. The results showed that 108694 unigenes were found. N50 was 593.90bp, and the mean length was 912bp. By comparing with Nr and Swiss-prot database, 40915 unigenes were annotated, and 67779 unigenes were unannotated. In addition, 30 unigenes had homology with Ces family, 20 unigenes had homology with Cls family, and 11 unigenes had homology with SuSy. 11369 unigenes were assigned to 25 categories with COG database, and 21378 unigenes were divided into 52 GO terms. Function annotation against KEGG database obtained 8087 unigenes and 118 pathways. 47 unigenes were found at “phenylpropanoid biosynthesis” pathway. Furthermore, 4908 unigenes contained 5179 SSRs, 1 SSR occurred every 12.46kb. The largest number of SSR type was mono-nucleotide repeat, and its frequency was 54.37%; the next was di-nucleotide repeat and tri-nucleotide repeat, with the frequencies of 22.90% and 21.70%, respectively. These results greatly enriched the genetic information of G. delavayi, and provided basic data for genetic breeding and exploitation of this unique plant resource.

De novo assembly and characterization of Rhododendron hybridum Hort. (Ericaceae) global transcriptome using Illumina sequencing

Project description:Rhododendron hybridum Hort. (Ericaceae) is an important ornamental species with striking continuous flowering feature. However, few genomic resources are currently available in this species, and the breeding programs were handicapped by the lack of basic genetic information. Here, we established a transcriptomic profiling study from four different tissues using RNA-Seq to gain insight on the functional genes and to isolate EST-SSR markers for breeding and conservation purposes. In total 38,050,296 high-quality sequence reads were obtained, and 56,120 unigenes (with N50 = 1,236bp) were assembled. Of which, 32,580 (58.05 %) and 8,788 (15.66 %) were annotated to GO and KEGG database, respectively. Additionally, 38,775 (69.09 %) and 37,409 (66.66 %) R. hybridum unigenes were aligned to the Arabidopsis thaliana and Oryza sativa genome, respectively. A total of 21,103 simple sequence repeat (SSR) motifs were identified in 15,050 contigs. Among them, dinucleotide repeats account for the largest proportion for 49.27%, followed by mono- (35.94%) and trinucleotide (21.5%). This study represents the first transcriptome data of R. hybridum and confirms that the transcriptome assembly data are a useful resource for EST-SSR loci development. Such vast sequence data and markers will be robust tools for genomic research and breeding of R. hybridum and related species.

Desumoylation of the RNA polymerase III lies at the core of the Sumo-Stress Response

Project description:Posttranslational modification by the small ubiquitin-like modifier Sumo regulates many cellular processes including the adaptive response to various types of stress, which has been referred to as Sumo Stress Response (SSR). However, it remains unclear whether the SSR involves a common set of core proteins regardless of the type of stress, or whether each particular type of stress induces a stress-specific SSR that targets a unique, largely non-overlapping set of Sumo substrates. In this study we used mass spectrometry to identify differentially sumoylated proteins during heat shock, hyperosmotic stress, oxidative stress, nitrogen starvation and DNA alkylation in Saccharomyces cerevisiae. Our results show that each stress triggers a specific SSR signature centered on proteins involved in transcription, translation, and chromatin regulation. Strikingly, while the various stress-specific SSRs were largely non-overlapping, all types of stresses tested here resulted in desumoylation of subunits of RNA polymerase III, which correlated with a decrease in tRNA synthesis. We conclude that desumoylation and subsequent inhibition of RNA polymerase III constitutes the core of all stress-specific SSRs.

Transcriptome analysis and molecular marker discovery in red pepper, Capsicum annuum L. TF68

Project description:Transcriptome from high throughput sequencing-by-synthesis is a good resource of molecular markers. In this study, we present utility of massively parallel sequencing by synthesis for profiling the transcriptome of red pepper (Capsicum annuum L. TF68) by 454 GS-FLX pyrosequencing. Through the generation of approximately 30.63 megabases (Mb) of Expressed Sequence Tags (ESTs) data with the average length of 375 base pairs (bp), 9,818 contigs and 23,712 singletons were obtained by assembly. Using BLAST alignment against NCBI non-redundant and a UniProt protein database, 30% of the tentative consensus sequences were assigned to specific function annotation, while 24% returned alignments of unknown function, leaving up to 46% with no alignment. Functional classification using FunCat revealed that sequences with putative known function were distributed cross 18 categories. Furthermore, over 200 high quality single nucleotide discrepancies were discovered using the Bukang cDNA collection as a reference database. Moreover, 758 simple sequence repeat (SSR) motif loci were mined from over 600 contigs, from which 572 primer sets were designed. The SSR motifs corresponded to di- and tri- nucleotide motifs (27.03 and 61.92%, respectively). These molecular markers may be of great value for application in linkage mapping and association mapping research. 1 sample TF68 accession examined

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

Project description: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.

Characterization of the Rosa roxburghii Tratt transcriptome and analysis of MYB genes

Project description:Rosa roxburghii Tratt belongs to the Rosaceae family, and the fruit is flavorful, economic, and high nutritious, providing health benefits. MYB proteins play key roles in R. roxburghii’ development and fruit quality. However, the available genomic and transcriptomic information are extremely deficient. Here, a normalized cDNA library was constructed using five tissues, stem, leaf, flower, young fruit, and mature fruit, with three repetitions, and sequenced using the Illumina HiSeq 3000 platform. De novo assembly was performed, and 470.66 million clean reads were obtained. In total, 63,727 unigenes, with an average GC content of 42.08%, were determined and 59,358 were annotated. In addition, 9,354 unigenes were assigned the Gene Ontology category, and 20,202 unigenes were assigned to 25 Eukaryotic Ortholog Groups. Additionally, 19,507 unigenes were classified into 140 pathways of the Kyoto Encyclopedia of Genes and Genomes database. Using the transcriptome, 163 unigenes associated with MYB were detected. Among these genes, there were total 75 genes which strikingly expressed in various tissues, including 10 R1 MYB, 42 R2R3 MYB, 1 R1R2R3 MYB, 3 MYB and 19 atypical MYB-like proteins. The expression levels of 12 MYB genes randomly selected for qRT-PCR analysis were consistent with the RNA-seq results. A total of 37,545 microsatellites were detected, with an average EST-SSR frequency of 0.59 (37,545/63,727). This transcriptome data will be valuable for identifying genes of interest and studying their expression and evolution.
