From: Intronization, de-intronization and intron sliding are rare in Cryptococcus
Most cases of non-conserved boundaries have nearby in frame candidate alternative boundaries. Lower/upper case sequence indicates intronic/exonic sequence as defined for JEC21. A. Intron 1 of gene CND03550. The JEC21 TAG 3' intron boundary is mutated to TGG in H99 (single underline). H99 may use the downstream CAG instead (double underline). B. Intron 1 of gene CNC04760. The JEC21 CAG 3' intron boundary is mutated to CAA in WM276 (single underline). WM276 may use the downstream TAG instead (double underline). In all cases, intron numbers are given in reference to the coding sequence.
