Abstract

Internal transcribed regions (ITS1 and ITS2) of 11 different fungi, i.e. 8 species of Alternaria, Nimbya gomphrenae, Stemphylium vesicarium, and Ulocladium botrytis, were sequenced. Their phylogenetic relationships with another 36 species in Pleosporaceae in GenBank were analyzed by parsimony and distance methods. These two methods positioned filament-beaked Alternaria as a monophyletic group discrete from the other members in genus Alternaria. A hypothesis proposing that the filament-beaked speices of Alternaria evolved a particular evolutionary route distinguishable from other species based on molecular evidence, the unique traits of morphological adaptation for liberation and their subsistent strategies has been discussed.
