Taxonomy

cellular organisms - Eukaryota - stramenopiles - Oomycetes - Peronosporales - Phytophthora - Phytophthora infestans

Phytophthora infestans is heterothallic (sexes reside in different individuals) oomyctete (water mold). For a long time oomycetes were considered as close relatives of Fungi such as ascomyctetes (various molds, yeasts) and basidiomycetes (mushrooms, rusts and others). However, studies of metabolism, cell wall composition, and rRNA sequence indicate that oomycetes are more properly grouped with chrysophytes, diatoms, and brown algae.
