Overview of the KO number statistics

DNA RNA
Bacteria Archaea Bacteria Archaea
Average KO numbers 5721 ± 546 2927 ± 152a 5839 ± 564 2511 ± 330a
Significant higher KO numbers 663 630 2522 338

Significant (P < 0.001) differences, as determined by a t test, between bacteria and archaea or between DNA and RNA are indicated by letter “a”. Significant higher KO numbers were determined based on a significant higher relative abundance on DNA or RNA level
