Oomycete Fungi: Their Phylogeny And Relationship To Chromophyte Algae
View through CrossRef
Abstract
The phylogenetic relationships within the oomycete fungi are described with emphasis placed upon the organization of their zoospores and encysted spores. On the basis of zoospore and cyst structure it is proposed that the Oomycetes fall into four main groupings. These can be reduced to two major groupings: the ‘saprolegnian clan’ and the ‘peronosporalean clan’. The former is characterized by zoospores possessing ‘encystment vesicles’, which upon zoospore settlement are released to form the outer electrondense cyst wall in which distinctive preformed hairs are embedded. This group includes almost all members of the Saprolegniales and Leptomitales, as well as many Lagcnidialian genera such as Haliphthoros, Olpidiopsis, and Lagenisma.
