Plant metabarcoding from sedaDNA of Siberian and Alaskan lake sediment cores
The dataset contains raw files from NGS sequencing using Illumina devices. In total, eight data sets containing forward (*.R1.fastq.gz) and reverse (*.R2.fastq.gz) files are provided from amplicon sequencing of sediment samples from lake sediment cores (sedaDNA). Therefore, 3 to 5 g of sediment was used in the PowerMaxÂ® Soil DNA Isolation Kit (Qiagen, Germany) resulting in 504 sedaDNA extracts. The sedaDNA was concentrated and purified with the GeneJET PCR Purification Kit (ThermoFisher), then PCR replicates using the trnL g and h primers were performed and PCR products were purified using the MinElute PCR Purification Kit (Qiagen). Finally, the PCR replicates were pooled equimolarly and sequenced in paired-end mode (2x150bp) on a HiSeq or NextSeq Illumina platform run by the Fasteris Genesupport SA sequencing service (Switzerland). The following eight sequencing runs are included:   - Lake Bilyakh (lake core: PG1755, sequencing run ALRK-8, forward file: 190910_NB501473_A_L1-4_ALRK-8_R1.fastq.gz, reverse file: 190910_NB501473_A_L1-4_ALRK-8_R2.fastq.gz)  - Lake Bolshoi Toko (lake core: PG2133, sequencing run HUA-9,  forward file:170927_SND393_A_L006_HUA-9_R1.fastq.gz, reverse file: 170927_SND393_A_L006_HUA-9_R2.fastq.gz )  - Lake E5 (lake core: E5-1A, sequencing run ALRK-13,  forward file: 201117_NB501473_A_L1-4_ALRK-13_R1.fastq.gz,   reverse file: 201117_NB501473_A_L1-4_ALRK-13_R2.fastq.gz)  - Lake Emanda (lake core: Co1412, sequencing run APMG-42,  forward file: 210914_NB501850_A_L1-4_APMG-42_R1.fastq.gz,  reverse file: 210914_NB501850_A_L1-4_APMG-42_R2.fastq.gz)  - Lake Ilirney (lake core: EN18208, sequencing run ALRK-10,  forward file: 201117_NB501473_A_L1-4_ALRK-10_R1.fastq.gz,  reverse file:201117_NB501473_A_L1-4_ALRK-10_R2.fastq.gz)  - Lake Ilirney (lake core: 16-KP-01-L02, sequencing run ALRK-5,  forward file: 190531_NB501850_A_L1-4_ALRK-5_R1.fastq.gz, reverse file: 190531_NB501850_A_L1-4_ALRK-5_R2.fastq.gz)  - Lake Levinson Lessing (lake core: Co1401, sequencing run ALRK-11,  forward file: 201117_NB501473_A_L1-4_ALRK-11_R1.fastq.gz,  reverse file: 201117_NB501473_A_L1-4_ALRK-11_R2.fastq.gz)  - Lake Rauchuagytgyn (lake core: EN18218, sequencing run APMG-30,  forward file: 210602_NB501850_A_L1-4_APMG-30_R1.fastq.gz,  reverse file: 210602_NB501850_A_L1-4_APMG-30_R1.fastq.gz)
