We studied the zinc and lead accumulation and tolerance level of suspended cells of four Viola species with different metallophyte statuses: Viola lutea ssp. westfalica (obligate metallophyte), V. tricolor (facultative metallophyte), V. arvensis (accidental metallophyte) and V. uliginosa
The cellular distributions of Pb and As in the leaves of co-hyperaccumulator Viola principis H. de Boiss. were inspected by synchrotron X-ray fluorescence spectroscopy (SRXRF). The results revealed that Pb and As had similar compartmentalization patterns in the leaves. Both elements were enriched in
The cyclotides are the largest family of naturally occurring circular proteins. The mechanism by which the termini of these gene-encoded proteins are linked seamlessly with a peptide bond to form a circular backbone is unknown. Here we report cyclotide-encoding cDNA sequences from the plant Viola
