The replication of ribosomal DNA in the macronucleus of Tetrahymena
Chromosoma, 1977The replication of extrachromosomal rDNA molecules from the macronucleus of Tetrahymena was studied by electron microscopy. Replication begins in the center of the palindromic molecule and proceeds by means of bidirectional fork movement toward the free ends of the molecule.

H4 Histone in the Macronucleus of "Blepharisma japonicum"
1997Two clones, obtained by polymerase chain reaction from macronuclear DNA of the unicellular ciliated protist Blepharisma japonicum, were isolated and sequenced. They correspond to fragments of two different putative H4 histone genes. The existence of multiple H4 histone genes was also suggested by Southern blot hybridisation experiments employing one of

[Symbiotic bacteria of the macronucleus of Paramecium caudatum].
Tsitologiia, 1975Particles of a newly described endosymbiont of Paramecium caudatum, clone M-115, here referred to as iota--particles, are Gram--negative bacteria. The symbionts are only present within macronuclei and not in the cytoplasm or in the micronuclei. The cells of clone M-115 iota do not display any killer-effect when mixed with "clean" cultures of Paramecia.
