The intriguing complexity of parthenogenesis inheritance in Pilosella rubra (Asteraceae, Lactuceae)
Popis výsledku v původním jazyce
The study is focused on the inheritance of parthenogenesis in Pilosella (Asteraceae). A complex pattern was recorded in the segregating F1 progeny from reciprocal crosses between the facultatively apomictic hexaploid P. rubra and the sexual tetraploid P.officinarum. The actual transmission rates of parthenogenesis were significantly correlated with the mode of origin of the respective progeny class. The inheritance was significantly reduced in n + n progeny from the cross where parthenogenesis was transmitted by female gametes. In n + 0 polyhaploid progeny, the transmission rate of parthenogenesis was high. Reduced female gametes transmitting parthenogenesis preferentially developed parthenogenetically and only rarely were fertilized in P. rubra. We observed the different expression of complete apomixis in 2n + n hybrids as compared to their apomictic maternal parent. We suggest that this difference is a result of unspecified interactions between the parental genomes.
