Histologic, metabolomic, and transcriptomic differences in fir trees from a peri-urban forest under chronic ozone exposure.

ABSTRACT: Urbanization modifies ecosystem conditions and evolutionary processes. This includes air pollution, mostly as tropospheric ozone (O₃), which contributes to the decline of urban and peri-urban forests. A notable case are fir (Abies religiosa) forests in the peripheral mountains southwest of Mexico City, which have been severely affected by O₃ pollution since the 1970s. Interestingly, some young individuals exhibiting minimal O₃-related damage have been observed within a zone of significant O₃ exposure. Using this setting as a natural experiment, we compared asymptomatic and symptomatic individuals of similar age (≤15 years old; n = 10) using histologic, metabolomic, and transcriptomic approaches. Plants were sampled during days of hi
