Project description:We describe an application of deep sequencing and de novo assembly of short RNA reads to investigate small interfering (si)RNAs mediated immunity in leaf samples from eight tree taxa naturally occurring in Wytham Woods, Oxfordshire, UK. BLAST search for homologues of contigs in the GenBank identified siRNA populations against a number of RNA viruses and a Ty1-copia retrotransposons in these tree species. Small RNA sequencing and de novo assembly
Project description:Cotyledons and leaf transcriptomes of species of Salsoleae with different photosynthetic types were de novo assembled and analyzed to provide a better understanding of differential gene expression between C3, C2 and C4 species. Total RNA of cotyledons and leaves of different species of Salsoleae with different photosynthetic types (C3 Salsola webbii, C2 Salsola divaricata, C4 Salsola oppositifolia, C4 Hammada scoparia) were isolated with RNeasy Plant Mini Kit (Qiagen) following Standard protocol (January 2011) and including DNase Digestion with RNase-Free DNase Set (Qiagen). 500 ng were used for cDNA library generation conducted with TruSeq RNA Sample Preperation Kit (Illumina Inc.) following Low Sample Protocol (TruSeq RNA Sample Preparation v2 Guide, Illumina Proprietary, Part # 15026495 Rev. C, May 2012). Sequencing of single reads was performed on an Illumina HiSeq2000 platform.

Project description:We sequenced and assembled de novo the coding transcriptomes in four species of Notothenioid fish: Neopagetopsis ionah (Jonah’s ice fish), Pseudochaenichtys georgianus (South Georgia icefish), Harpagifer antarcticus (Antarctic spiny plunderfish) and Parachaenichthys charcoti (Charcot’s dragonfish). We sampled 1-4 individuals and 1-14 tissues (brain, white muscle, liver, head kidney, trunk kidney, skin, heart, red muscle, spleen, ovary, testis, whole blood, gill, red blood cells) in each species, depending on tissue availability.
Project description:We first report the use of next-generation massively parallel sequencing technologies and de novo transcriptome assembly to gain insight into the wide range of transcriptome of Hevea brasiliensis. The output of sequenced data showed that more than 12 million sequence reads with average length of 90nt were generated. Totally 48,768 unigenes (mean size = 488 bp) were assembled through transcriptome de novo assembly, which represent more than 3-fold of all the sequences of Hevea brasiliensis deposited in the GenBank. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. Total 37,373 unigenes were successfully annotated and more than 10% of unigenes were aligned to known proteins of Euphorbiaceae. The unigenes contain nearly complete collection of known rubber-synthesis-related genes. Our data provides the most comprehensive sequence resource available for study rubber tree and demonstrates the availability of Illumina sequencing and de novo transcriptome assembly in a species lacking genome information.

Project description:To understand the biosynthesis of C. majus BIAs, we performed de novo transcriptome sequencing of leaf and root tissues of C. majus using Illumina high-throughput sequencing technology.
