Hi @Alban_OTT, It is definitely true that you will sometimes see organelle rRNA sequences in your data, and they will often be classified during taxonomy classification. For example, in Greengenes, mitochondrial rRNA are often classified as: k__Bacteria; p__Proteobacteria; c__Alphaproteobacteria; o__Rickettsiales; f__mitochondria; ... and chloroplast rRNA are often classified as: k__Bacteria; p__Cyanobacteria; c__Chloroplast; .... (Chloroplasts descend from Cyanobacteria, and mitochondria f…

We often recommend removing these sequences prior to analysis.
