Diseases of Fungi Questions

Question 1

Submit Answer 1

Answer 1

By having single genotypes present at high densities, any pathogen present compatible with the genotype has an unlimited access to a huge resource. The initial population of the pathogen is likely to increase logarithmically. The effect on the host could be devastating. The potential damage caused by viral pathogens in fungi used in industrial production is therefore enormous.

Question 2

Submit Answer 2

Answer 2

Viruses have a comparatively small genome. Thus any mutation has a significant effect. Further, viruses are usually present in relatively large numbers and only one needs to mutate to initiate change within the population. Finally, viruses reproduce rapidly, so changes are potentially fast.
