Achiasmate meiosis in the Fritillaria japonica group

Abstract

SummaryThe Fritillaria japonica group consists of six related species with x=12 and its derivative x=11. Irrespective of basic chromosome number, the pollen and embryo sac mother cells in all these species show clearly different modes of bivalent formation.Although meiosis in EMC's of five species is typically chiasmate, PMC's of all six species show… (More)
