a, without paired end sequencing results.

b, assembled sequence plus estimated size of sequence gaps (estimations on the basis of paired end sequencing results).

c, not counting pseudogenes.

d, corresponding to CDS annotated as “fragment”.

e, numbers in italics represent data after genome finishing.

*The increase in the number of contigs after genome finishing is due to the addition of sequence fragments in the original sequence gaps.
