Question

Quizplus · Accepted Answer

Phytophthora ramorum primarily reproduces through asexual spore production, which allows it to quickly spread and infect new areas. Hikers walking through infected areas can inadvertently pick up the spores on their boots or shoes, which can then be transported to uninfected areas, thereby spreading the fungus. Fragmentation, colonization, and budding are not common modes of reproduction for this fungus.
