but whether such ecological functions persist after they form SOAs was previously unknown. Here we show that Scots pine seedlings damaged by large pine weevils feeding on their roots release HIPVs that trigger defenses in neighboring conspecific plants. The biological activity persisted after HIPVs had been oxidized to form SOAs。

这种生物活性仍然存在， Silja Saarela， and reduced weevil damage. The elemental composition and quantity of SOAs likely determines their biological functions. This work demonstrates that plant-derived SOAs can mediate interactions between plants， highlighting their ecological significance in ecosystems.

Zijun Li，但在其形成SOA后是否仍具备这种生态功能此前尚不清楚，SOA的元素组成和数量可能决定其生物功能，生物源SOA可通过植物挥发物在大气中的氧化形成， James D. Blande IssueVolume: 2024-09-13 Abstract: Biogenic secondary organic aerosols (SOAs) can be formed from the oxidation of plant volatiles in the atmosphere. Herbivore-induced plant volatiles (HIPVs) can elicit plant defenses。
