Project description:Orchidaceae are renowned for their spectacular flowers as well as other reproductive and ecological adaptations. After the genome of the tropical epiphytic orchid Phalaenopsis equestris was sequenced, we combined Trinity data for de novo assembly and Illumina HiSeq1500 data for RNA-Seq analysis to characterize the transcriptomes of four different organs for a better understanding of the molecular mechanisms driving these characteristics. We present four de novo assembled transcripts reconstructed from RNA collected from the root, stem, leaf, and flower of Phalaenopsis equestris. These sets of transcripts greatly enrich the available data for Phalaenopsis equestris. Here, we present two databases, and each dataset allows for a different type of search for candidate homologues. The first dataset consists of the sets of assembled unigenes, which enable a sequence-based search. A comprehensive analysis of the assembled unigenes revealed the unigenes from root, stem, leaf, and flower with high e-values aligned versus the Nr, Swiss-Port, KEGG, COG, and GO database, respectively. This analysis enabled the production of a second database, which includes sequences correlated with annotated transcript names as well as the confidence of the best hit from BLAST.

The transcriptome of embryos of the green anole, Anolis carolinensis, at 28 and 38 somite pair stages

Project description:Anolis carolinensis embryos were collected 0-1 days post egg laying, and total RNA was extracted for RNA-Seq analysis (Illumina Hi-Seq2000). Transcriptome sequence from these stages in the green anole, equivalent to mouse 9.5-10.5 dpc embryos, will help to improve gene annotations in A. carolinensis and provide expression level information for key organogenesis and patterning processes. Anolis carolinensis embryos were collected 0-1 days post egg laying for RNA-Seq analysis. The two embryos collected were at 28 somite-pair (28S) and 38 somite-pair (38S), equivalent to mouse 9.5 dpc and 10.5 dpc embryos, respectively. Total RNA was extracted using the total RNA component of the mirVana (Ambion) kit, RNA-Seq library prep was carried out using the NuGEN Ovation RNA-Seq kit, and sequencing was carried out on an Illumina HiSeq 2000, following the manufacturer's protocol. The untrimmed data was then aligned to the Anolis carolinensis reference genome (Anocar2.0) using tophat.
