What is the meaning of Oomycete?

The oomycetes, also known as “water molds”, are a group of several hundred organisms that include some of the most devastating plant pathogens. The diseases they cause include seedling blights, damping-off, root rots, foliar blights and downy mildews.

What are Oomycete cell walls made of?

Oomycete cell walls consist mainly of cellulose, β-1,3 and β-1,6 glucans (Bartnicki Garcia 1968; Mélida et al., 2013). Unlike fungi, which are devoid of cellulose, oomycetes contain cellulose as a main cell wall component, representing at least 30% of the total cell wall carbohydrates.

Why water mold are called Oomycota?

17.3: Oomycota — The Water Molds. Oomycetes (a term used to refer to organisms in the phylum Oomycota) are a group of fungus-like organisms that rely on water for completion of their life cycle, hence the common name “water molds”.

Is Fusarium a Oomycete?

The primary fungal and oomycete genera reported as containing species that are pathogenic toward apple, include the fungal genera Cylindrocarpon, Fusarium and Rhizoctonia, and the oomycete genera Phytophthora and Pythium (Sewell 1981; Dullahide et al.

Is powdery mildew An Oomycete?

Biology of the Oomycetes You may be surprised to learn that true fungi, such as the organisms that cause powdery mildew, black rot, phomopsis, and botrytis, are more closely related to animals than they are to oomycetes (Figure 1)!

Why are oomycetes not considered fungi?

The Oomycota have long been considered fungi because they obtain their nutrients via absorption and many of them produce the filamentous threads known as mycelium characteristic of many fungi. None of the true Fungi produce oospores.

Is water mold protozoans or Chromists?

Why are they classified as chromists rather than as protozoans or fungi? Water molds are classified as chromists because their cell walls are made of cellulose. Explain one way in which some chromists, such as algae, can reproduce sexually. In some chromists, haploid parent cells produce haploid gametes by mitosis.

What is the meaning of oomycetes?

Definition of Oomycetes. : a subclass of parasitic of saprophytic fungi (class Phycomycetes) that includes water molds, white rusts, and downy mildews and that is distinguished from the Zygomycetes by having the gametangia usually differentiated into antheridia and oogonia and by producing oospores as a result of the sexual process. —.

How are the eggs of oomycetes fertilized?

The eggs are fertilized by antheridia that penetrate the oogonium and deliver nuclei to the eggs. The oomycetes were formerly classified among the fungi because their filamentous bodies resembled fungal hyphae. The phylum includes several species that cause important plant diseases, such as late blight.

How do oomycetes reproduce asexually?

Oomycetes have cell walls made of cellulose or similar substances, and store their food as glycogen. They reproduce asexually by the formation of diploid spores (called zoospores) with two flagellae. Sexual reproduction involves the formation of a number of eggs within a structure called an oogonium.

What is the role of calcium in oomycete pathogens?

Calcium and other plant nutrients have been used in disease management of oomycete pathogens.
