Cytogenetic peculiarities of cell genesis in apical meristems under gametophytic apomixis (using autonomous apomicts of the Asteraceae as an example)

Kashin A.S., Tsvetova M.I., Demochko Yu.A.

Cytogenetic peculiarities of cell genesis in apical meristems of apomicts has been analyzed using a series of the Asteraceae species as an example. The extent to which aneu- and mixoploids are spread among plants in the investigated populations of the Asteraceae species is so high (up to 30–60 % of the studied plants and their offspring), that it seems reasonable to suppose that their rise is a natural phenomenon. It has been shown that in the aposporous facultative apomict Pilosella officinarum microgametophyte is a relatively stable element of the seed reproduction system from the point of view of caryotypical variation.
