#dnaderived #sequences #barcoding #Cortinarius Added another several dozens of sequences to our Fungarium YSU database, which soon will be discoverable though GBIF. Hope to find collaboration through shared barcoding initiatives. Especially like these days Cortinarius spp., they are amazing.
Totally about 1K specimens in our collection have dna-derived data (attached sequences): https://www.gbif.org/dataset/d922b606-6c94-4d51-9277-36c9b03872a7

Excellent paper from F Keck.

Reference barcoding libraries problems:
(i) mislabelling, (ii) sequencing errors, (iii) sequence conflict, (iv) taxonomic conflict, (v) low taxonomic resolution, (vi) missing taxa and (vii) missing intraspecific variants. They give possible consequences on the taxonomic assignment process

RT by @Plants_EFSA: Behind the scenes, indentify #2 : @aimethods DNA Barcoding.

Black-headed leafcutter bee, Megachile circumcincta. The DNA was isolated from a leg of the bee using a liquid (lysis buffer). Means everything dissolves in it except for the chitin. Then the Co1 gene was amplified with PCR. This means that certain parts of the DNA are copied so often that they are easily detectable. Detectable for the sequencer, the next step. The 313 base pairs required for the identification are then determined here. (See colorful graphic) With the help of a worldwide database of already certain animals whose Co1 gene has been determined, the base pairs can be compared with each other.

Proud to contribute to the #eDNA part of this review on #BioMonitoring of #marine #invasive #alien species in Europe, as part of the #GES4SEAS project. Have a look, esp. if you wondered how many #NIS species for which sequence vouchers exist for #DNA #barcoding or #metabarcoding
