The grass Dichanthelium lanuginosum lives in hot soils and houses fungi of the genus Curvularia as endophytes. Researchers tested the impact of Curvularia on the heat tolerance of this grass. They grew plants without (E−) and with (E+) Curvularia endophytes at different temperatures and measured plant mass and the number of new shoots the plants produced.

Accepted Answer

Hello everyone here we have a question that tells us an end a fight IQ fungus was found to be present in a plant's roots. Upon testing its soluble izing property. It was confirmed that the fungi can solid belies the different types of insoluble organic phosphate without affecting the soil Ph provided that phosphate soluble Izing microorganisms PSM have two means of phosphate soluble soluble ization, phosphate taste slash fi taste production and organic acid production. Which of the following statements is true. A PSm soluble ISES phosphate through organic acid production. If this was true, the soil ph would lower so A is incorrect. Beat psm soluble ISES phosphate through phosphate taste, Fi taste production. This is true. See PSM isolated from the roots is ineffective and phosphate soluble ization. This is incorrect. The PSM uses both phosphates and organic acid and phosphate solid realization. Again, if we're using organic acid, there would be lower ph And we are saying that the soil ph is not being affected so D. Is incorrect. So our answer here is B PSM solid realizes phosphate through phosphate slash fi taste production. Thank you for watching. Bye.
