Project description:We performed one degradome sequencing for identification and characterization of novel microRNAs in Phalaenopsis aphrodite subsp. formosana. Plant tissues of leaves, stalk, and flower buds frozen in liquid nitrogen were ground to fine powder using a mortar and pestle, respectively. Total RNA extraction was freshly prepared using Trizol (Invitrogen, Carlsbad, CA, USA) following the manufacturer's instructions. About 50 μg of leaves with or without low temperature treatment, stalks and flower buds were taken separately and then mixed. The degradome library was constructed by the Genomics BioSci & Tech. Company following the manufactoring protocol. In brief, 200 μg of total RNA was passed though polyA column using the Oligotex kit (Qiagen). The 5'-RNA adapter containing a Mme I recognition site was ligated by T4 RNA ligase and further reverse transcribed to amplify the templates. After digesting with Mme I then ligated to a 3'-double DNA adapter, the products were amplified by additional PCR cycles and gel-purified for Illumina sequencing. The files contain the raw data of degradome sequencing. Examination of one degradome of mixed tissues of Phalaenopsis orchid
Project description:We performed four small RNA sequencing for identification and characterization of microRNAs in Phalaenopsis aphrodite subsp. formosana. By comparing the low temperature-treated group with treated group, we concluded four miRNAs - miR156, miR162, miR528 and miR535 - as low temperature-induced miRNAs. In addition, tissue-specific expression of these miRNAs was investigated. The files contain the miRNAs analysis results in each group. Examination of low temperature-treated leaves and two other organs of Phalaenopsis orchid
Project description:Viral siRNA generated from antiviral RNA silencing machinery was profiled using small RNA sequencing from Phalaenopsis orchid mixed infected with CymMV and ORSV
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.
