A cytokinetic ring- driven cell rotation achieves Hertwig's rule in early development

). Since the mitotic spindle is bisected during cell division for proper chromosome segregation, the axis along which the mitotic spindle is oriented determines the axis of cell division (13). Hence, the orientation

In vitro haploid zygotic embryogenesis due to pollination with maize pollen and induced in vitro androgenesis in Czech wheat breeding genotypes

Induction of haploid zygotic embryogenesis and androgenesis was studied in 72 and 31 wheat genotypes, respectively. Green zygotic plants (haploids only) were and spontaneous polyhaploids) were observed in 17 genotypes (55 %). In
