And evolution © springer-verlag 1999 printed in austria inactivation of pollen and other effects of genome-plastome... An incompatibility between genome B and plastome IV is expressed in the haplo- and diplophase: (1) B-IV pollen, though normally developed, is largely inactive....
An experimental system for the molecular analysis of the aging process : the budding yeast saccharomyces cerevisiae... Because haploids and diploids can multiply vegetatively by mitotic cell division, both the haplophase and the diplophase can be stably main-tained....
A comparative analysis of ontomorphogenesis of the gametophytes of two epilithic ferns asplenium adiantum-nigrum and adiantum capillus-veneris l.... The following types of ontogenesis are tracked:full and reduced functionally finished ontogenesis with reproduction of diplophase (sporophytes), and also full andreduced functionally not finished ontogenesis....
Sex and the spread of retrotransposon ty3 in experimental populations of saccharomyces cerevisiae... Ty3 frequencies increased above 80% in all sexual populations in which transposition was induced in haplophase or in diplophase....
