🌾 Subdivision Basidiomycotina
Important features and disease relevance of Basidiomycotina in plant pathology.
Basidiomycotina includes highly significant plant pathogens, especially rusts and smuts that cause major yield losses in cereals and other crops.
Defining Characters
Core features:
- Septate mycelium.
- Sexual spores (basidiospores) formed externally on basidia.
- Often complex life cycles with specialized spore stages.
Rust and Smut Importance
Economically critical disease groups:
- Rust fungi: often obligate parasites, sometimes with alternate hosts.
- Smut fungi: systemic or localized infections in floral and vegetative organs.
Epidemiological Relevance
Basidiomycotan pathogens commonly produce huge spore loads and can spread over long distances by air, driving regional epidemics.
Control Perspective
Management depends on resistant cultivars, seed treatment where relevant, field sanitation, and timely fungicide use based on crop-pathogen system.
