A multi-techniqueandmulti-disciplinaryapproachwasappliedfortheinvestigationofHelichrysum microphyllum subsp. tyrrhenicum samples, bulk soil, and rhizospheres collected from a metal-extremeenvironment(Zn-PbmineofCampoPisano,SWSardinia,Italy).Zinc,Pb,andCd are the most abundant metals, with Zn attaining 3 w/w% in the rhizosphere solid materials, inducing oxidative stress in the roots as revealed by infrared microspectroscopy (IR). X-ray diffraction (XRD), scanning electron microscopy (SEM), and chemical analysis coupled with synchrotron radiation-based (SR) techniques demonstrate that quartz, dolomite, and weddellite biomineralsprecipitateinroots,stems,andleaves,likelyasaresponsetoenvironmentalstress.In therhizosphere,ZnchemicalspeciationismainlyrelatedtotheZnoreminerals(smithsoniteandhydrozincite) whereas, in plant tissues, Zn is primarily bound to organic compounds such as malate,cysteine,andhistidinemoleculesthatactasmetalbindersand,eventually,detoxification agents for the Zn excess. These findings suggest that H. microphyllum subsp. tyrrhenicum has developed its own adaptation strategy to survive in polluted substrates, making it a potential candidateforphytostabilizationaimedatmitigatingthedispersionofmetalsinthesurrounding areas. |
