    Author: Shang X, He Y, Zhang L, He CJ, Xia LX, Gao S, Guo YQ, Cheng HH, Zhou RJ.
    Journal: Yi Chuan; 2005 Mar; 27(2):227-30. PubMed ID: 15843350.
    Abstract:
    8 cDNA clones have been isolated from a cDNA library prepared from swamp eel testies by macroarray. DNA sequence analysis and database search showed that they encode 8 proteins which are highly homologous to 40S ribosomal proteins S4,S9,S16,S17,S20 and 60S riobosomal proteins L7, L18a,L29. Phylogenetic trees (ML) based on ribosomal protein genes from swamp eel and other organisms has been reconstructed, which showed that ribosomal protein genes were highly conserved during evolution. These results suggested that ribosomal protein genes as house keeping genes may play roles in developmental regulation such as sexual differentiation and can also be used as markers for the study of molecular evolution.
