These structures penetrate the epidermal cells of the plant’s tissue and form haustoria. Haustoria invade the plant intracellularly to retrieve nutrients while further dispersing the pathogen within the host. Chlamydospores that survive in the soil produce mycelia that can also infect plant structures.
Plant tissues are invaded by these structures, which create haustoria. These haustoria then enter the plant cells to obtain nutrients while spreading the pathogen throughout the host. The chlamydospores that remain in the soil give rise to mycelia, which can also infect plant tissues.
