摘要	The presence of diatoms in victim's internal organs has been regarded as a gold biological evidence of drowning. The idea becomes true at the advent of DNA metabarcoding. Unfortunately, the DNA barcode of diatoms are far from being applicable due to neither consensus on the barcode and nor reliable reference library.In this study we tested 23 pairs of primers, including two new primer pairs, Baci18S (V4 of 18S) and BacirbcL (central region of rbcL), for amplifying fragments of 16S/18S, 23S/28S, COI, ITS and rbcL. A total of five pairs of primers performed satisfactory for diatoms. We used three of them, 18S605 (V2 + V3 of 18S), Baci18S and BacirbcL, to barcode four water samples using next generation sequencing platform. The results showed that these primers worked well for NGS metabarcoding of diatoms. We suggest that 18S605, Baci18S and BacirbcL be barcodes of diatoms and the corresponding primer pairs be used. Considering a quite high proportion of sequences deposited in GenBank were mislabeled, the most urgent task for DNA barcoding of diatoms is to create standard sequences using correctly identified specimens, ideally type specimens.
