Question

Hi everyone!

I'm performing 18S taxonomy analysis with qiime2, and I would like to download the ncbi sequences and it's associated taxonomy, if that's possible.

Thanks in advance,
Jose

NCBI makes a curated collection of LSU and SSU subunit sequences available with their pre-computed blast indexes. Look for files with those names. You can extract the fasta sequences using blastdbcmd program contained in blast+ package. Taxonomy files are available in the same directory.
