Studying allozyme variation in sexual and apomictic Taraxacum and Pilosella (Asteraceae) populations

Abstract: Allozyme spectra of peroxidase, esterase, superoxid dismutase, tyrosinase, alcohol dehydrogenase, lactate dehydrogenase, and acid phosphatase were examined in populations of sexual ( Taraxacum serotinum and Pilosella echioides ) and apomictic ( T. officinale and P. officinarum ) plant species. The heterozygosity in these populations (0. 455-0.620) proved to be considerably higher than the average level characteristic of plant populations (0.058-0.185). The populations examined did not differ in the mean phenot… Show more

“…The supernatant was absorbed onto filter paper wicks, which were then stored at -80°C for further electrophoretic analysis. Electrophoresis was carried out following a previously described method for isozymes analysis (Kashin et al 2005). Three enzyme systems were used for the examination of variation, including peroxidase (PRX, EC 1.11.1.7), esterase (EST, EC 1.15.1.1) and superoxide dismutase (SOD, EC 1.15.1.1).…”

“…As codominant markers, they can help elucidate origins of polyploids (Roose and Gottlieb 1976;Soltis and Rieseberg 1986;Soltis and Soltis 1989;Mahy et al 2000;Rosquist and Prentice 2002;Crawford et al 2006) or hybrids (Brochmann et al 1992;Gauthier et al 1998;Mráz et al 2005) and indirectly estimate the breeding system within a population (Sipes and Wolf 1997;Sydes and Peakall 1998). Allozymes are especially suitable for detection of differences in population genetic structure between sexual and apomictic taxa (Bayer and Crawford 1986;Hughes and Richards 1988;Yahara 1990;Bayer 1991;Noyes and Soltis 1996;Hörandl et al 2000Hörandl et al , 2001Hörandl and Greilhuber 2002;Kashin et al 2005) due to different levels and patterns of heterozygosity and genotypic diversity. Allozymes have been used successfully also in several population genetic studies in the genus Pilosella Kashin et al 2005;Peckert et al 2005;Tyler 2005;Bruun et al 2007;Krahulcová et al 2009a).…”

In our previous paper, we used allozymes to compare the genetic diversity between the populations of P. ullepitschii from the core area (Western Carpathians) and isolated populations originated from Romanian Eastern and Southern Carpathians (Šingliarová et al 2008).…”

“…By the present, quite a big array of data that prove genetic and epigenetic polymorphism in agamospermous plant progenies has been obtained (Richards, 1986;Levites et al, 1998;Maletskii et al, 1998;Chapman et al, 2000;Levites et al, 2001a, b;Verhoeven et al, 2010). Genetic polymorphism was investigated in such progenies using marker enzymes in the whole number of contributions (Richards, 1986;Yahara et al, 1991;Szkutnik et al, 2001;Љtorchovб et al, 2002;Hцrandl, 2004;Kashin et al, 2005).…”
