How to find all WGS assemblies accessions of a species Some background
Similar to the OP of https://www.biostars.org/p/377840/, I would like to programmatically BLAST a sequence to a local database of all WGS assemblies.
Since this isn't feasible for the average biology lab server (correct me if I am wrong), I plan to use ncbi-acc-download to download all WGS assemblies of the species of interest (not a popular species like E. coli, so it should be feasible). Then, I will create a BLAST database for the downloaded assemblies and BLAST the sequence to it.
My question
How can I find all WGS assemblies accessions of a species?


My current plan is to search the NCBI Assembly database using Entrez and a search term such as &quot;wgs&quot;[Properties] AND txid1337[orgn:exp].
EDIT: IIUC, this approach might miss some WGS assemblies. See my answer.
I am worried (and thus ask for your help) this isn't the right approach because there seem to be at least 3 other places in which assemblies can be found:

The assembly_summary.txt files that are described in https://ftp.ncbi.nlm.nih.gov/genomes/README_assembly_summary.txt.
https://www.ncbi.nlm.nih.gov/Traces/wgs/. This is the one I am most worried about. Both because it seems to have much more entries, and also because https://www.ncbi.nlm.nih.gov/genbank/wgs/ says: &quot;The public WGS projects are at the list of WGS projects .&quot;
taxid2wgs.pl. (As mentioned in https://www.biostars.org/p/377840/#471535, this one seems to miss some assemblies.)
There seem to be WGS assemblies that can't be found in NCBI Assembly database, e.g.: https://www.ncbi.nlm.nih.gov/nuccore/1779902990. I guess that such assemblies also cannot be found in The assembly_summary.txt files that are described in https://ftp.ncbi.nlm.nih.gov/genomes/README_assembly_summary.txt.
My current best guess is that each WGS assembly has a &quot;WGS master record&quot; in NCBI Nuccore database. To find all WGS assemblies of a taxon whose uid in NCBI Taxonomy database is 1337, search NCBI Nuccore database using Entrez and the search term &quot;wgs master&quot;[Properties] AND txid1337[orgn:exp].
