Cultivation of the Russian dandelion (Taraxacum koksaghyz) as a rubber producing crop was abandoned more than 50 years ago. [] Key Result Morphological examination and genetic analyses demonstrated that all available ex situ germplasm collections of T. koksaghyz belonged to a single triploid apomictic clone that was misidentified as T. koksaghyz.
Analysis of wild Taraxacum bicorne Dahlst. (Compositae–Crepidinae) as a potential alternative natural rubber crop
Taraxacum koksaghyz Rodin, a dandelion from the steppes of south-eastern Kazakhstan, has been known for long time as potential rubber producer, as a temperate region alternative to the tropical
Population Genetics of the Rubber-Producing Russian Dandelion (Taraxacum kok-saghyz)
The Russian dandelion, Taraxacum kok-saghyz, is a perennial species native to Central Asia that produces high quality, natural rubber and simple-sequence repeat markers from available expressed-sequence tag (EST) data were developed and used to investigate patterns of population genetic diversity in this nascent crop species.
Selectivity of herbicides in Russian dandelion (Taraxacum kok-saghyz L. Rodin).
Russian dandelion (Taraxacum koksaghyz; Tks) belongs to the plant family of asteraceae and to the few latexproducing plants whose cultivation is of economical interest. Already before and during WWII
Multilocus DNA polymorphism of some rubber-bearing dandelions (Taraxacum spp.) of Russia and Kazakhstan
The aim of this work was to search of RAPD, ISSR, and SSR markers for the unambiguous identification of all studied dandelion forms and found the ISSR primers HB10,ISSR17, and ISSR36 were most effective for detecting interspecific polymorphism.
In vitro plant regeneration from ovules of Taraxacum officinale and Taraxacum koksaghyz
This study focused on gynogenesis because analysis of microsporogenesis showed that very small (young) inflorescences already contain mature pollen and that the development of the microspores is not synchronous in different flowers in one inflorescence, resulting in shoot formation from ovules.
Taraxacum kok-saghyz (rubber dandelion) genomic microsatellite loci reveal modest genetic diversity and cross-amplify broadly to related species
It is revealed that TKS has low- to- moderate genetic diversity with most of it partitioned to the individuals and individuals within populations, whereas the species lacked population structure.
Chloroplast genome resources and molecular markers differentiate rubber dandelion species from weedy relatives
The availability of chloroplast genomes of these three dandelion species, as well as chloroplow and nuclear molecular markers, will provide a powerful genetic resource for germplasm differentiation and purification, and the study of potential gene flow among Taraxacum species.
Temporal diversity of Taraxacum kok-saghyz plants reveals high rubber yield phenotypes
Across all growing conditions and developmental stage, the highest rubber yields per plant were found in plants with large roots combined with a large rosette, and an above average rubber concentration, and rubber concentration was heritable.


Characterization of rubber particles and rubber chain elongation in Taraxacum koksaghyz
It is proposed that the recently described T. koksaghyz CPTs are the major rubber chain elongating enzymes in this species, and could be used as a model species for the investigation and comparison of rubber biosynthesis.
A review of literature onTaraxacum koksaghyz Rod
A survey of the Russian literature on rubber-bearing plants in general and on kok-saghyz is carried out, restricted to those papers that are to be found in certain American and Canadian Libraries and hence are most readily available to the North American investigator.
Russian dandelion ( Taraxacum kok-saghyz ): one more example of overcollecting in the past?
Taraxacum kok-saghyz is a rubber producing plant that once was a strategie source of natural rubber in Soviet Union but with no current usage as a crop species. In this paper we 1) review the
Polyphenoloxidase Silencing Affects Latex Coagulation in Taraxacum Species1[W]
Latex fluidity analysis in silenced plants showed a strong correlation between residual PPO activity and the coagulation rate, indicating that laticifer-specific PPO plays a major role in latex coagulations and wound sealing in dandelions.
Taraxacum koksaghyz Rodin definitely is not an example of overcollecting in the past. A reply to S. Volis et al. (2009)
Taraxacum koksaghyz is documented here as a relatively common species at suitable habitats within its whole known range, a list of populations studied is given and the species is briefly characterized.
Results of hybridization experiments between twenty-six species of Taraxacum (nine of which are sexual) are reported, with most crosses set good seed and there is no evidence of seed-incompatibility.

Molecular Cloning and Characterization of Rubber Biosynthetic Genes from Taraxacum koksaghyz
The deduced TkCPT amino acid sequences showed significant levels of sequence identity with Hevea brasiliensis CPTs, and there were no obvious differences between SRPPs from T. koksaghyz, another rubber producer, and a non-rubber plant.
Extraction and characterization of latex and natural rubber from rubber-bearing plants.
The comparative studies indicated that optimum latex extraction can be achieved with Flow method, and the purity of latex extracted by Blender method was significantly lower than that extracted by Flow method.
Alternative sources of natural rubber
A complementary approach to guayule with yeast species is set up, which may more quickly show the applicability and relevance of genes selected and the risk of crop failure, diminishing acreage, and other disadvantages outlined below.
