說明

The MycoPins method is a protocol to monitor early colonization events in communities of wood-inhabiting fungi in fine woody debris. The sampling dataset presented here is based on fieldwork from a time series experiment on standard sterilized poplar pins (furniture wooden dowels 1 cm diameter, 3 cm length) that were placed in soil to decay, then collected and subjected to DNA metabarcoding analysis and automated molecular identification of species. The list of species for each sampling point during the duration of the experiment was produced by a taxonomic classifier PROTAX (Abarenkov, 2018). PROTAX analyses the DNA sequences and provides with a table of reliably identified (probability >0.9) species, which is about 10% of the overall sequences from our experiment. The list of published species is limited to only 10% because while identifying the species, PROTAX takes into the account the uncertainty and mislabelings in the UNITE database that was used as a reference.

計畫資料

MycoPins is a straightforward method for studying and monitoring dead wood colonization by fungi. The method combines standardized fieldwork sampling that includes experimental exposure of wooden pins to lignicolous fungi in the environment, followed by subsequent metabarcoding analysis of fungal DNA from the colonized pins.

計畫名稱 MycoPins: a metabarcoding-based method to monitor fungal colonization of fine woody debris
研究區域描述 The study was concluded in a suburban area of central New Jersey, USA, from December 2020 to May 2021.

取樣方法

Sterilized poplar pins (wooden dowels) 1 cm in diameter and 3 cm long were placed in triplicates on November 23rd, 2020 in soil 2 cm from the surface, covered with debris and allowed to decay. Pins were extracted after 14, 28, 42, 77 and 160 days. Each pin was saved as an event, with parent events assigned to each date of extraction. Upon extraction, two pins for each triplicate were wrapped in brown paper and dried for 5 hours at 45°C in a conventional food dehydrator, and one pin was frozen at -80°C. Two sterile negative control pins were exposed to air in the field for 30 min and then one was dried and one frozen using the same methods used to store sample pins.The interior of each pin was drilled by a 2 mm fire-sterilized drill bit, DNA was isolated and PCR for the ITS2 gene region from the extracted DNA was carried out with the primers fITS7 forward (F), 5’-GTGARTCATCGAATCTTTG, and ITS4 reverse (R), 5’-TCCTCCGCTTATTGATATGC (Clemmensen, 2016). PCR amplicons were sequenced using an Illumina 2x 250 paired-end (PE) configuration.

研究範圍 The sampling event was performed from December 2020 to May 2021 in a suburban area of central New Jersey, Northeast of USA.
品質控管 During pre-processing of the sequencing data, raw pair-end sequences were merged using PEAR (Zhang et al, 2014), cutadapt (Martin 2011) was used for trimming and removing adapter/tag sequencing, and sequences were clustered using VSEARCH (Rognes et al, 2016) with 99% sequence similarity threshold. The resulting centroid sequences were processed with PROTAX (Abarenkov et al, 2018). Identification of species was performed using UNITE v 7.1 database. When calculating abundances of different taxa, the cluster sizes were taken into account. A sample-taxon table was produced as an output where the abundances were counted as the number of sequences whose taxon membership probability exceeded a 0.9 threshold (reliable identification). The resultant lists of species for each event (species in each pin) are shared in this dataset publication.
