Chapter 32, Problem 8TYK
Summary Introduction
To determine:
The disadvantages of constantly spraying fungicides in the soil even if there is no sign of fungal infection.
Introduction:
Plants are impacted by a wide variety of factors that can affect their growth. These factors can be disease or lack of nutrition. Many microorganisms such as

Black spot fungus is a disease that is known to attack roses in humid climates. At
first, small black spots appear on the leaves. If left untreated, the entire plant can
die. From this information, what is mostly the main cause of the demise? *
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.
The black spot fungus is known to attack roses in humid climates. Initially, small black spots appear on the leaves. The entire plant can die if not treated. From this information, what is mostly the main cause of the demise?

- Developing antifungal drusg is more difficult than developin antibacterial drugs. compounds that harm fungi more frequently cause side effects in humas than compounds that harm bacteria. Explain why this is the case, given the evolutionary relationship among bacteria, fungi, and humas.arrow_forwardIn a clinical laboratory we are interested in recovering a pathogenic fungus. What is the middle of most suitable crop? Why?arrow_forwardThe fungus Botrytis cinerea is a pathogen of plants, and causes high losses of strawberry crops around the world. In Europe, most B. cinerea fungi are killed by fungicides (chemicals sprayed on the crops to kill the fungus). However, some B. cinerea are resistant, and continue to live even when exposed to fungicides. If the currently-used fungicides continue to be sprayed on strawberry crops in Europe, what is expected to happen? (Choose one.) a)The strawberries will eventually become larger and more resistant to fungicides. b)The strawberries will form a beneficial association (mutualism) with the B. cinerea, and both will be resistant to the fungicides. c)Strawberry plants will preferentially be colonized by B. cinerea that are not resistant to fungicides. d) The proportion of B. cinerea that are resistant to fungicides will increase in the population over time, and these fungicides will no longer be effective at killing most of these fungi.arrow_forward
- Worldwide, frog populations are in decline. Several different fungi have been implicated in (thought to be the cause of) decreases in frog numbers. In particular, shrub frogs are especially at risk. You test several different fungi species to see how they affect sample populations of splotched frogs, a close relative of the shrub frog that is not endangered. To do this, you use the different species of fungi to infect populations of splotched frogs and then measure survival rates of these frogs at different frog densities. Frog densities are given in column 1 of the table below. The frog population in column 2 is the control, which was not infected with a fungus. Initial density of frog population (before introduction of Frog survival Frog survival Frog survival Frog survival Frog survival rate rate rate rate rate Control Fungus Fungus Fungus B. grenchius Fungus B. sporifera B. noeltid B. talbuta fungus) Per 1000 m2 10 0.95 0.72 0.83 0.90 0.5 50 0.9 0.64 0.82 0.87 0.35 75 0.88 0.66…arrow_forwardThe roots of most plants form a symbiotic association with soil fungi.

- The specific relationship between a legume and its mutualisticRhizobium strain probably depends on(A) each legume having a chemical dialogue with a fungus.(B) each Rhizobium strain having a form of nitrogenase thatworks only in the appropriate legume host.(C) each legume being found where the soil has only theRhizobium specific to that legume.(D) specific recognition between chemical signals and signalreceptors of the Rhizobium strain and legume species.arrow_forwardWhich of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.arrow_forwardWhat is one distinct feature of fungi that could be exploited for antibiotic therapy?arrow_forward
