Five haploid and three diploid yeast strains of various species (Yarrowia lipolytica, Pichia pinus and Pichia guilliermondii) were irradiated with alpha-particles from 239Pu and gamma-rays from 137Cs or 60Co in the stationary phase of growth. A common feature of these species is that they exhibit a

[Genetic disorders in the pollen cells of waxy barley in radioactive contamination after the Chernobyl accident].

Ostapenko EK, Vilenski? ER, Naumenko VD, Bubriak II, Grodzinski? DM.AbstractGenotoxic effects during microsporogenesis and gametogenesis were studied in barley of the waxy strain grown on 3 experimental plots situated in the region of the Chernobyl disaster (plot 1 in the town of Chernobyl, plots 2 and 3 in the town of Yanov, 3 km away from the damaged power plant). It was determined that an increased level of radionuclide pollution and chronic irradiation during ontogenesis results in higher incidence of meiotic disturbances and abnormalities during formation of the male gametophyte. Incidence of waxy reversions in pollen grains depends on the activity of radionuclide pollutants as well. We suggest that selection affecting both diplont and haplont forms will provide for the absence of significant aberrations in subsequent plant generations.

… In respect of propagation of rice by propagules initiated on the ears, a very interesting point needs mentioning that the plants produced from the propagules encircled their life cycles by the diplont nuclear phase only omitting its sexual phase which is related to the formation of pollens and egg cells and their fertilization. …
