a - pseudogenes were not calculated in the SE11 genome paper
b - includes size of plasmids
The total number of genes, tRNA, other ncRNAs and IS elements in each strain includes pseudogenes/pseudo-tRNAs etc.; the number of pseudo-elements in each case is noted in brackets. Note that ncRNAs are not annotated/incompletely annotated in SE11 and E24377A, respectively; conseqeunctly, the absolute number of genes shown for these strains is inaccurate. ND = not determined in annotation.
