Simultaneous Estimation of Taraxerol and Taraxasterol in Root Callus Cultures of Taraxacum officinale Weber

A simple, selective, rapid, precise and economical reverse phase high -pressure liquid chromatographic method has been developed for the first time for the simultaneous estimation of Taraxerol and Taraxasterol, in natural root and root callus cultures of Taraxacum officinale (TO) , maintained on MS media using hormone combinations , MS+IAA+BA (2ppm+1ppm) and MS+IAA+BA+2,4 D (0.5ppm+1ppm+0.5ppm)...

Genotypic variation within asexual lineages of Taraxacum officinale.

Restriction site variation in DNA that encodes rRNA (rDNA) was surveyed among 714 offspring within 31 lineages (26 genotypes) of obligate asexually reproducing Taraxacum officinale (dandelions). Although clonal offspring are expected, plants with nonparental rDNA were produced from two parents that were themselves siblings (same genotype). The variation is best characterized by the loss of an E...
