“…Most of the known chromosome numbers for apomictic Taraxacum species are at a triploid level (2n = 3x = 24), especially those of the widespread European sections Taraxacum sect. Taraxacum (Mártonfiová 2006, Kula et al 2013), T.sect.Erythrosperma (Małecka 1967, 1969, Vašut 2003, Schmid et al 2004, Vašut et al 2005, Uhlemann 2007, 2010, Vašut and Majeský 2015, Wolanin and Musiał 2017), T.sect.Palustria (Małecka 1972, 1973, 1978, Kirschner and Štěpánek 1998b, Marciniuk et al 2010) and T.sect.Hamata (Mogie and Richards 1983, Øllgaard 1983). However, tetraploids (2n = 4x = 32) also occur quite frequently in some sections, such as the European dandelions in sections T.sect.Palustria (e.g., T.vindobonense Soest, 1965, T.brandenburgicum Hudziok, 1969 and T.portentosum Kirschner & Štěpánek, 1998), T.sect.Erythrosperma (e.g., T.tortilobum Florström, 1914, T.fulvum Raunkiaer, 1906 and T.bifurcatum Hagendijk et al, ineditus), T.sect.Naevosa (e.g., T.euryphyllum (Dahlstedt, 1911) M.

The species-rich and widespread genus Taraxacum F. H. Wiggers, 1780 (Asteraceae subfamily Cichorioideae) is one of the most taxonomically complex plant genera in the world, mainly due to its combination of different sexual and asexual reproduction strategies. Polyploidy is usually confined to apomictic microspecies, varying from 3x to 6x (rarely 10x). In this study, we focused on Taraxacum sect. Taraxacum (= T.sect.Ruderalia; T.officinale group), i.e., the largest group within the genus. We counted chromosome numbers and measured the DNA content for species sampled in Central Europe, mainly in Czechia. The chromosome number of the 28 species (T.aberrans Hagendijk, Soest & Zevenbergen, 1974, T.atroviride Štěpánek & Trávníček, 2008, T.atrox Kirschner & Štěpánek, 1997, T.baeckiiforme Sahlin, 1971, T.chrysophaenum Railonsala, 1957, T.coartatum G.E.

Øllgaard & Štěpánek, 1997, T.subhuelphersianum M.P. Christiansen, 1971, T.valens Marklund, 1938) is 2n = 3x = 24. The DNA content ranged from 2C = 2.60 pg (T.atrox) to 2C = 2.86 pg (T.perdubium), with an average value of 2C = 2.72 pg. Chromosome numbers are reported for the first time for 26 species (all but T.diastematicum and T.obtusifrons), and genome size estimates for 26 species are now published for the first time.

Recurved Taraxacum phyllaries function as a floral defense: experimental evidence and its implication for Taraxacum evolutionary history

Florivores directly decrease the reproductive success of plants by consuming pollen and seeds; thus, plants often have defense mechanisms against florivory. Here, we show that the recurved phyllaries of an agamospermous hybrid dandelion, Taraxacum japonicum · officinale, function as a physical barrier to slug florivory. We allowed Lehmannia valentiana, a European slug naturalized in Japan, to feed on eight pairs of the hybrid dandelion and T. japonicum, a Japanese species with erect phyllaries. Consequently, the slugs only damaged T. platycarpum flowers. The slugs either moved back from recurved phyllaries or spent more than twice as long on recurved than on erect phyllaries. When we removed the recurved phyllaries, the slugs stayed on hybrid and T. japonicum phyllaries for equal lengths of time. In addition to recurved outer phyllaries, the hybrid dandelion has erect inner phyllaries that are longer than those of T. japonicum, which effectively conceal the florets at night protecting them from slug florivory. Using the taxonomic literature, we have confirmed that recurved phyllaries evolved in many species in several parts of Europe, but are rare in East Asia. These findings suggest that European dandelions acquired recurved phyllaries as a defense mechanism under antagonistic coevolution with florivorous slugs, but this coevolution did not occur in East Asia.
