Project description:cDNA library sequencing in the midgut, mixed segment and first proctodeal segment of worker termites in Nasutitermes takasagoensis by 454 GS Junior pyrosequencing
Project description:Contaminated aquifer (Dusseldorf-Flinger, Germany) templates extracted from 5 sediment depths ranging between 6.4 and 8.4 m below ground and over 3 years of sampling were amplified for amplicon pyrosequencing using the primers Ba27f (5’-aga gtt tga tcm tgg ctc ag-3’) and Ba519r (5’- tat tac cgc ggc kgc tg-3’), extended as amplicon fusion primers with respective primer A or B adapters, key sequence and multiplex identifiers (MID) as recommended by 454/Roche. Amplicons were purified and pooled as specified by the manufacturer. Emulsion PCR (emPCR), purification of DNA-enriched beads and sequencing run were performed following protocols and using a 2nd generation pyrosequencer (454 GS FLX Titanium, Roche) as recommended by the developer. Quality filtering of the pyrosequencing reads was performed using the automatic amplicon pipeline of the GS Run Processor (Roche), with a slight modification concerning the valley filter (vfScanAllFlows false instead of TiOnly) to extract the sequences. Demultiplexed raw reads were furhter trimmed for quality and lenght (>250 bp).
Project description:Four cDNA libraries from immature embryos, mature embryos, microspore derived embryos and mature leaves were constructed. cDNA were sequenced by the Roche-454 GS-FLX.
Project description:This data series contains the sequences and read counts of Piwi-interacting RNAs and other small RNAs from mouse and rat testes extracts. In a search for different classes of small RNAs that might be involved in transcriptional gene silencing, we encountered a novel class of small RNAs within mammalian testes. This study reports the identification of small RNAs and their relative abundance levels to each other based on the deep coverage of the cDNA library.
