Detailed Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Q: Question: Does an aboveground pathogen inhibit belowground rhizobia and arbuscular mycorrhizal fungi in Phaseolus vulgaris?
Answer: We demonstrate that aboveground fungal pathogens can affect belowground mutualism with two very different types of microbial symbionts-rhizobia and AMF. Our results suggest that systemically induced PPO activity is functionally involved in this above-belowground interaction. We predict that the top-down effects we show here can drastically impact plant performance in soils with limited nutrients and water; abiotic stress conditions usually mitigated by microbial belowground mutualists.
A:
yes
