Hi @sabrinatoro @egchr [#543](https://github.com/The-Sequence-Ontology/SO-Ontologies/issues/543) may be relevant here

Hi @murphyte Apologies if I over-interpreted your comments on the discussion doc and libeled your previous #485 ticket! :-( _We could shift the children up a level, and redefine sncRNA...

I think the main problem is that the current SO has **both** these terms (and problematic defs): sncRNA: A non-coding RNA less than 200 nucleotides in length. lncRNA: A non-coding...

Works for me. Then we can annotate that pesky 199nt ncRNA as an lncRNA after all :-)

Note that we have already updated the lncRNA definition in #575 to this: A non-coding RNA generally longer than 200 nucleotides that cannot be classified as any other ncRNA subtype....

Current SO defs for sncRNA/sncRNA_gene are: sncRNA (SO:0002247) A non-coding RNA less than 200 nucleotides in length. sncRNA_gene (SO:0002342) A ncRNA_gene that encodes an ncRNA less than 200 nucleotides in...

Hi @davidwsant So, if we want to mirror the revised rRNA tree structure exactly, I think we need: ``` rRNA_gene |_cytosolic_rRNA_gene (NEW) |_cytosolic_LSU_rRNA_gene (NEW) |_cytosolic_2S_rRNA_gene (RENAME) |_cytosolic_23S_rRNA_gene (RENAME) |_cytosolic_25S_rRNA_gene (RENAME)...

@egchr There's been no work at all on this ticket AFAIK. Compare the the tree in my previous comment to that at http://sequenceontology.org/browser/current_svn/term/SO:0001637 Would be very happy if you could...

Hi @egchr Thanks for addressing my other ncRNA tickets! Would be great if this one could also be addressed ahead of the RNAcentral meeting next week.

Thanks @egchr ! SO:0002241 (rRNA_21S_gene) could be made a secondary ID of the new 'mt_LSU_rRNA_gene' term, to at least preserve the ID for searching etc. (I think that's what happened...
