Intron positions in the transferred α-amylase gene homologous to Phchr1|7087| found in Fungi. Pink dots: phase 0 introns; green dots: phase 1 introns; blue dots: phase 2 introns. Shaded regions represent unknown sequences. The black bar is a region of uncertain annotation. Asterisks indicate possible cases of intron sliding. CBM20 indicates the presence of an additional carbohydrate binding module of the CBM20 family. The number of introns is meant without the CBM20 extension.
