Question

Fungal hyphae are able to penetrate the host with the help of

• A. Mechanical pressure
• B. Softening by enzymes
• C. Both A and B
• D. Suckers and hooks

Answer 1

The correct option is C Both A and B

Host tissue penetration is likely to involve a combination of hyphal tip pressure and the hydrolytic activity of fungal exo-enzymes. Turgor pressure and the secretion of wall tensioning and degradative enzymes must be coordinated at the site of growth to promote tissue penetration.

Thus, the correct answer is option C.
