Albugo - Wikipedia

WebThe high abundance of the motifs in the predicted secretome repertoires of several unrelated haustoria-forming obligate biotrophic fungal species (i.e., many that cause leaf and stem rusts, or powdery mildew) ( Godfrey et al., 2010) is intriguing and may be exploitable in the future. Albugo candida, commonly known as white rust, is a species of oomycete in the family Albuginaceae. It is sometimes called a fungus, but in fact forms part of a distinct lineage of fungus-like microorganisms, Oomycetes, commonly known as water moulds. A. candida is an obligate plant pathogen that infects Brassicaceae species and causes the disease known as white rust or white blist… Albugo is a genus of plant-parasitic oomycetes. Those are not true fungi (Eumycota), although many discussions of this organism still treat it as a fungus. The taxonomy of this genus is incomplete, but several species are plant pathogens. Albugo is one of three genera currently described in the family Albuginaceae, the taxonomy of many species is still in flux. poston immaval
