ABSTRACT: the de novo genome sequencing of four Rhododendron plants (Rhododendron liliiflorum, Rhododendron decorum, Rhododendron platypodum, and Rhododendron concinnum) Raw sequence reads
Project description:Purpose: The goals of this study are to compare the gene expression profiling for drought treated and control plants by using NGS. Methods: The four RNA samples were pooled to one, using equivalent quantities of each sample for transctiptome sequencing. Meanwhile, the four RNA samples were used to construct the library for DGE sequencing. Results: Using Illumina sequencing technology, we generated over two billion bases of high-quality sequence data on H. ammodendron and conducted de novo assembly and annotation of genes without prior genome information. These reads were assembled into 79,918 unigenes (mean length=728 bp).In addition, DGE reads were mapped to the assembled transcriptome for gene expression analysis under drought stress. In total, 1,060 differentially expressed genes were identified.
Project description:In this study, we aim to present a global transcriptome analysis of medicinal plant, Catharanthus roseus. We generated about 343 million high-quality reads from three tissues (leaf, root and flower) using Illumina platform. We performed an optimized de novo assembly of the reads and estimated transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses among tissue samples. We collected different tissue samples from the mature plants. Total RNA isolated from these tissue samples was subjected to Illumina sequencing. The sequence data was further filtered using NGS QC Toolkit to obtain high-quality reads. The filtered reads were used for de novo assembly optimization. The reads were further mapped to the Catharanthus transcripts via CLC Genomics Workbench and differential gene expression analysis was performed using DESeq software.
Project description:We developed a software package STITCH (https://github.com/snijderlab/stitch) to perform template-based assembly of de novo peptide reads from antibody samples. As a test case we generated de novo peptide reads from protein G purified whole IgG from COVID-19 patients.

In total, 1,060 differentially expressed genes were identified. H. ammodendron seedlings grew for one month, and then one set of seedlings were treated with a one-week (7d) stress, and the second set of seedlings was used as a control and received no treatment. Each treatment was with two replicates.
Project description:These data corresponds to RNA-Seq assays obtained from the body wall of farmed I. badionotus juveniles samples. These raw reads were used to evaluate differential gene expression between wild and farmed Isostichopus badionotus specimens. With this aim, a de-novo transcriptome assembled from wild specimens was used as reference. Further information about de-novo assembled transcriptome is available within the BioProject PRJNA639785.
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.
Project description:Crassulacean acid metabolism (CAM) is a water-use efficient adaptation of photosynthesis that has evolved independently many times in diverse lineages of flowering plants. We hypothesize that convergent evolution of protein sequence and temporal gene expression underpins the independent emergences of CAM from C3 photosynthesis. To test this hypothesis, we generated a de novo genome assembly and genome-wide transcript expression data for Kalanchoe fedtschenkoi, an obligate CAM species within the core eudicots with a relatively small genome (~260 Mb). Our comparative analyses identified signatures of convergence in protein sequence and re-scheduling of diel transcript expression of genes involved in nocturnal CO2 fixation, stomatal movement, heat tolerance, circadian clock and carbohydrate metabolism in K. fedtschenkoi and other CAM species in comparison with non-CAM species. These findings provide new insights into molecular convergence and building blocks of CAM and will facilitate CAM-into-C3 photosynthesis engineering to enhance water-use efficiency in crops.
