Overview of genome annotation statistics. a) the distribution of the lengths of the genes of the O. ulmi with G. clavigera and N. crassa. b) the number of introns in each of the predicted genes in O. ulmi. Most of the predicted genes have either zero or one introns and a few of them have more than 5 introns. c) distribution of the length of the introns of the gene models. The majority of the introns are 60 bp to 200 bp and 3% of them are between 200 bp and 300 bp. Almost 8% are longer than 300 bp but are not shown in the figure for the purpose of clarity.
