Ribosomal RNA Adenine Dimethylase Domain Containing Protein 1 (RRNAD1)

RRNAD1 belongs to the UPF0431 family. Diagnostic signature DNA sequences are important tools for the identification of species. There is an active debate in the literature on the choice of the best markers applicable for a broad range of organisms. Protists have seldom been included in these evaluations. Mitochondrial gene sequences are inappropriate for protists since several groups do not possess mitochondria.

The genera of Cardiocladius and Eukiefferiella; Rheocricotopus and Psectrocladiue were sister groups respectively, which were well defined by the former morphological data. The D1 region of 28S ribosomal DNA genecan provide considerable phylogenetic information on thegeneric and tribal level in Chironomidae.
