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...

Complete chloroplast genomes from apomictic Taraxacum (Asteraceae): Identity and variation between three microspecies
Chloroplast DNA sequences show substantial variation between higher plant species, and less variation within species, so are typically excellent markers to investigate evolutionary, population and genetic relationships and phylogenies. We sequenced the plastomes of Taraxacum obtusifrons Markl. (O978); T. stridulum Trávniček ined. (S3); and T. amplum Markl. (A978), three apomictic triploid (2n =...
متن کاملThree Novel Triterpenoids from Taraxacum officinale Roots.
Three novel lupane-, bauerane-, and euphane-type triterpenoids (1-3), in addition to seven known triterpenoids (4-10)-18β,19β-epoxy-21β-hydroxylupan-3β-yl acetate (4), 21-oxolup-18-en-3β-yl acetate (5), betulin (6), officinatrione (7), 11α-methoxyolean-12-en-3-one (8), eupha-7,24-dien-3-one (9), and 24-oxoeupha-7,24-dien-3β-yl acetate (10)-were isolated from the roots of Taraxacum officinale. T...
