Studies were made on the fine structure and chemical components of the synaptonemal complex (SC) of pollen mother cells of Tradescantia reflexa. The SC of T. reflexa consists of three partite structures: a central element consisting of two tubules of about 20 nm width, which are twisted together, a lateral element appearing as an electron-opaque line of 25-35 nm width, and transverse filaments of about 10 nm width which connect the central and lateral elements.
The central element contains basic protein and a small amount of DNA and RNA. The lateral element contains basic protein and small amounts of DNA and RNA. The transverse filaments contain non-basic protein.
