The creation of homozygous plants is essential for both genetic studies and the production hybrid seeds, particularly in that were pollinated by an alien species. Dihaploid (DH) technology important application obtaining lines used to plant speed breeding programs. generation haploid embryos pollen irradiation pollination female flowers with irradiated has been successfully applied. influence o...

Recently ovulated mouse oocytes at the Metaphase II stage undergo parthenogenetic activation (as indicated by the formation of pronuclei) when incubated for 6 h in the presence of cycloheximide or puromycin; the activation response increases progressively with the concentration of inhibitor. Activation is induced with concentrations of cycloheximide that depress protein synthesis by more than 7...

Worldwide, termites are one of few social insects. In this research, the stages embryonic development in parthenogenetic and sexual eggs Reticulitermes aculabialis R. flaviceps were observed described. flaviceps, egg FF FM groups happened during early phases development, whereas aculabialis, appeared mainly late phase development. The variance number micropyles between colony type was statistic...
