Intron insertion position, intron type, and endonuclease within the cox 1 , cox 3 , cob, nad 1 , nad 2 genes of Fusarium circinatum (FC)(JX910419), F. verticillioides (FV)(JN041210) , F. fujikuroi (FF) (JX910420) , F. oxysporum (FO) (AY945289), F. graminearum (FG)(DQ364632) and F. solani (FS) (JN041209). Each block colour represents a different group I intron: blue = group1A, red = group1B, grey = group1C, yellow = group1D and black = GroupII. The G inside the intron indicates the presence of a GIY-YIG endonuclease, while S indicate a single LAGLIDADG and D a double LAGLIDADG. Intron insertion positions are indicated below the intron and intron sizes are indicated above the intron.
