First she had to pick up jars of amoebas and parameciums for her students' experiments.
Thus a fragment of histone H4 gene (160bp) was sequenced in ten locally isolated strains of Paramecium species including a standing-alone on the basis of 18SrDNA gene sequence strain FT8.

Among them genus Paramecium of the oligohymenophorea ciliates is well studied in terms of its diversity, ultrastructure, physiology and genetics.
Especially, the sibling species of the Paramecium aurelia complex have been intensively studied because of their complex genomics and as an example of species radiation (Coleman, 2005; Aury et al.
Recently, investigations on H4 proteins for understanding of the evolutionary relationship of Paramecium species have increased tremendously.
2006) compared thirteen ciliates including Paramecium with other eukaryotes.
So the aim of the present study was to resolve the phylogenetic relationship of Paramecium species on the basis of analysis of H4 gene sequences.
