The origin of Taraxacum agamospecies
TLDR
The genus Taraxacum is thought that the genus arose in the west Himalayas during the Cretaceous and that apomixis arose at an early stage by means of polyploidy, precocious embryony and asynapsis in the female meiosis.About:

Patterns in plant parthenogenesis
TL;DR: Evidence is presented for plants, and by extension for animals as well, that high ploidy levels alone could (independent of breeding system) endow individuals with the ability to tolerate these ‘extreme’ environments.
Journal ArticleDOI
Pathogens, polymorphism, and the evolution of sex
TL;DR: The ecological and life-historical correlates of parthenogenesis, inbreeding, chromosome number, and polymorphism are consistent with the hypothesis that adaptation to one host genotype is negatively correlated with adaptation to others when host genotypes are sufficiently differentiated.

Mendelian Genetics of Apomixis in Plants
TL;DR: This review shows how molecular markers and superior phenotypic methods have been used to clarify the genetics of apomixis in monocots as well as dicots during the past 15 years.

Ecological and evolutionary opportunities of apomixis: insights from Taraxacum and Chondrilla
TL;DR: The ecological and evolutionary opportunities of apomixis in the short and the long term are considered, based on two closely related apomictic genera: Taraxacum and Chondrilla, which have a wider geographical distribution than sexuals and have a close phylogenetic relationship, suggesting that apomIXis in these two genera could be of common ancestry.

TL;DR: In this article, the origin and dispersal of a plant is discussed in the context of origin and migration of a species of a genus called "Flowering Plants" in the Middle East.

Eutriploid facultative agamospermy in taraxacum
TL;DR: It is shown that sexual diploids can give rise to triploid apparently as a result of fertilization by incompletely reduced pollen in triploids, the first report of eutriploid, facultative agamospermy in Taraxacum.
