Get all entries of genbank of genetically modified bacteria

Question

[leontp587]

Hello,

I'm doing a big data project and want to make a list of all bacteria entries in genbank which correspond to genetically modified sequences. It should include all (or at least most) types of genetic modification. Does anyone have any suggestions on how I can get started? Is there some kind of "artificial" tag on genbank entries? If not, is there some other creative way to do this?

Thanks!
