Project description:Phalaenopsis cornu-cervi is a taxonomically and horticulturally important moth orchid. In this study, we report and characterize the complete plastid genome sequence of P. cornu-cervi for the first genomic resources in section Polychilos. Its complete plastome is 147,241?bp in length and contains two inverted repeat (IR) regions of 25,005bp, a large single-copy (LSC) region of 85,714?bp, and a small single-copy (SSC) region of 11,517?bp. The plastome contains 110 genes, consisting of 76 unique protein-coding genes, 30 unique tRNA genes, and 4 unique rRNA genes. It also shows the typical characteristics of Phalaenopsis chloroplast genome, while all ndh genes are non-functional. The complete plastome sequence of P. cornu-cervi will provide a useful resource for future phylogenetic study of Phalaenopsis and its garden utilization.
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
