ncbi-rrna-data 6.1.20170106+dfsg1-4 (s390x binary) in ubuntu eoan

 This package contains some ribosomal RNA BLAST databases distributed
 as part of the NCBI C Toolkit that are too large and specialized to
 include in ncbi-data. Specifically, it contains the databases
 Combined16SrRNA, LSURef_93.fasta, LSU_nomito_nochloro_noplastid,
 SSURef_93.fasta, and SSU_nomito_nochloro_noplastid, along with alias
 files to facilitate searching some of them in conjunction with
 databases included in ncbi-data.
