What role do endophytes play in turfgrass?

Endophytes are beneficial fungi that live within the plant tissues of turfgrass and many other plants without causing any harm. Their primary role is to enhance the plant's resistance to various stresses, including insect pests and diseases. By doing so, endophytes contribute to improved turfgrass health, reducing the need for chemical pest control measures and promoting overall lawn vigor.

When endophytes colonize the grass, they produce specific compounds that deter herbivores and pathogens. This natural form of pest management is advantageous for maintaining healthy turfgrass in landscapes and athletic fields, as it minimizes the impact of external pest pressures. The relationship between endophytes and turfgrass not only supports its growth but also promotes ecological balance within the environment.

In contrast, the other options do not accurately reflect the function of endophytes. While seeds are essential for plant reproduction, endophytes do not produce them; they live within existing grass tissues. The assertion that endophytes feed on grass roots is also not true, as they do not derive their nutrients in that manner. Additionally, while endophytes contribute to a plant's overall health, they do not directly absorb nutrients from the soil, as that is the role of the plant's root system. Thus, understanding
