The reasons behind tolerance offungus for a wide range of environmental extremes in pH (potential of hydrogen), temperature, and osmotic pressure. Introduction: An optimum level of physical factors is vital for the survival of any organism. Any deviation from the latter results in the disruption of the cellular machinery and functioning. Change in temperature leads to the alteration in the level of saturation or unsaturation of fatty acids in the plasma membrane. A pH variation results in the alteration of the availability of metabolites and inorganic ions for the organism, which hinders normal cellular functioning. Osmotic pressure also plays an important role in solute uptake and maintaining cell homeostasis, so any change in this would also be lethal. Even then fungi can grow and reproduce in the diverse habitats and have potential to sustain a wide range of extreme environmental conditions with varying physical factors. This resistance is attained due to their distinct cellular morphology, ability to reproduce both asexually and sexually, and symbiotic relationships with other organisms.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
