abstract = {Polycyclic aromatic hydrocarbons (PAHs) are widespread globally, primarily due to longterm
anthropogenic pollution sources. Since PAHs tend to accumulate in soil sediments, liverwort
plants, such as Lunularia cruciata, are susceptible to their adverse effects, making them good models
for bioindicators. The aim of this study was to probe the impact of anthracene, a three-ring linear
PAH, on the growth parameters of L. cruciata and the relationship established with the internalization
of the pollutant throughout the phenology of the plant. Intrinsic plant responses, isolated from
external factors, were assessed in vitro. L. cruciata absorbed anthracene from the culture medium,
and its bioaccumulation was monitored throughout the entire process, from the gemma germination
stage to the development of the adult plant, over a total period of 60 days. Consequently, plants
exposed to concentrations higher than 50 μM anthracene, decreased the growth area of the thallus,
the biomass and number of tips. Moreover, anthracene also impinged on plant symmetry. This
concentration represented the maximum limit of bioaccumulation in the tissues. This study provides
the first evidence that architectural variables in liverwort plants are suitable parameters for their use
as bioindicators of PAHs.},
