Release of new version of DNA reference database for diatoms

As ecological research and biomonitoring increasingly explore and measure diatom diversity using molecular methods, it is becoming more and more crucial to ‘curate’ the sequence data in publicly available databases (such as GenBank and BOLD) to create a reliable reference database that can be used to identify High Throughput Sequencing DNA reads. This is because […]
