Abstract:Cardamine violifolia is
a Se hyperaccumulator
found in Enshi, China. In this study, spatial metallomics was applied
to visualize the distribution and speciation of Se in a single seed
of C. violifolia. It was found that
Se reached 1729.89 ± 28.14 mg/kg and the main Se species were
SeCys and SeMet in bulk seeds. Further in situ study on a single seed
found that the methylated Se species located mostly in the episperm.
This is the first visualized evidence of the in situ distribution
of methylated Se species in … Show more
