What structure does Rhizoctonia sp. have for resistance?

Rhizoctonia species form structures known as sclerotia, which serve as a crucial mechanism for resistance. Sclerotia are hardened masses of mycelium that are able to withstand unfavorable environmental conditions, such as drought, extreme temperatures, or lack of nutrients. These structures enable the fungus to survive in a dormant state until conditions become favorable for growth and reproduction, allowing Rhizoctonia to persist in the environment even when conditions are not conducive for active growth.

The formation of sclerotia is particularly advantageous as it provides a source of nutrition and a means of resilience against various stresses such as desiccation and competition from other organisms. When conditions improve, the sclerotia can germinate and produce new mycelial growth, leading to further propagation of the fungus.

In contrast, pseudopodia are extensions of certain cells primarily found in amoeboid organisms, which do not apply to fungal structures like those of Rhizoctonia. Fructification refers to the fruiting bodies produced by fungi but does not represent a structure specifically used for resistance. While hyphae are the filamentous structures of the fungal body, they do not have the same capacity for long-term survival and dormancy as sclerotia do. Therefore, among the
