A selenocystine-resistant carrot cell line, C-1, was isolated from a haploid carrot (Daucus carota) cell culture, HA. The C-1 variant takes up cystine, but not cysteine, more slowly than does HA. The selenocystine resistance is maintained in culture in the absence of selection and is expressed in regenerated plants. Results based on chromatographic separation of sulfur metabolites from cells fed with [(35)S]cystine suggest a block either in the uptake or reduction of cystine in the variant… CONTINUE READING
