- You have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image) By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.arrow_forwardWhat are some ways in which the relationship between a plant root and a mycorrhizal fungus is mutualistic?arrow_forwardAre all fungi detrimental for other organisms?

- The most important adaptive advantage associated with thefilamentous nature of fungal mycelia is(A) the ability to form haustoria and parasitize other organisms.(B) the potential to inhabit almost all terrestrial habitats.(C) the increased chance of contact between mating types.(D) an extensive surface area well suited for invasive growthand absorptive nutrition.arrow_forwardWhich phase of a fungal life cycle is best adapted to growing in ahost’s body?a. yeast b. hyphal c. conidial d. filamentousarrow_forwardWhat steps would it take for a fungus to establish a symbiotic relationship with plants? I understand that there are symbiotic soil fungi that are entangled amongst plant roots but this question I am wondering how they form a relationship if the fungus live between the plant cells.arrow_forward
- Mutualistic associations between fungi and the roots of plants are called (a) lichens (b) mycorrhizae (c) pathogenic associations (d) parasitic haustoria (e) mycotoxic symbiosesarrow_forwardAs noted in Section 46.7, mycorrhizal fungi help prevent carbon in the soil from escaping into the atmosphere. These fungi also benefit a host plant by providing it with a share of the phosphorus and nitrogen that their hyphae take up from soil. Most crop plants are capable of forming a relationship with mycorrhizal fungi, if any are present in the soil. Some people have suggested that inoculating soil with fungal spores could help reduce the use of industrially produced fertilizer. What are some potential advantages of using fungi, rather than chemical fertilizers, to enhance plant growth?arrow_forwardWhat term describes the close association of a fungus with the root of a tree? a. arhizoid b. a lichen c. a mycorrhiza d. anendophytearrow_forward
