What are the diseases caused by fungi in plants?
Leaf Diseases Caused by Fungi and Bacteria
- Leaf Spots. Leaf spots (other names: anthracnose, scab, leaf blotch, shot hole) are usually rather definite spots of varying sizes, shapes and colors.
- Leaf Blights.
- Rusts.
- Powdery Mildew.
- Downy Mildew.
What are examples of oomycetes?
Peronosporales
SaprolegnialesLeptomitales
Oomycete/Lower classifications
How do oomycetes infect plants?
Dispersal of oomycetes by wind or water is achieved through asexual sporangia. Germination of sporangia can occur either directly, forming invasive hyphae, or indirectly, releasing motile zoospores, which are chemotactically and electrotactically attracted to the surfaces of host plants (19).
What are the two major types of Oomycota?
The Oomycota is not a large group but is quite diverse, both in the appearance and the activities of its members. Although it has been divided up into as many as 30 families we generally view these organisms as being of two types, the water moulds and the plant parasites.
How many plant diseases are caused by fungi?
Plant pathology is the study of plant disease including the reasons why plants get sick and how to control or manage healthy plants. Collectively, fungi and fungal-like organisms (FLOs) cause more plant diseases than any other group of plant pest with over 8,000 species shown to cause disease.

What are plant diseases?
Plant disease is defined as the state of local or systemic abnormal physiological functioning of a plant, resulting from the continuous, prolonged ‘irritation’ caused by phytopathogenic organisms (infectious or biotic disease agents).
What are examples of Zygomycota?
Mucorales
MucoromycotinaZoopagomycotina
Zygomycota/Lower classifications
What are Biotrophs and Necrotrophs?
Biotrophs derive nutrients and energy from living cells, while necrotrophs derive their energy from dead or dying cells. Hemibiotrophs initially invade live cells prior to transitioning to a necrotrophic lifestyle to obtain nutrients from killing the host cells.
