Abstract:
Vitellogenin is an egg yolk precursor glycophospolipoprotein, which it can be used as a biomarker indicator in sexual
maturation. In this study, total of the nucleotide size for this partial VTG sequence is 574bp. The partial VTG nucleotide
homology of Hemibagrus nemurus is high; showing 88-91% identity between Clarias macrocephalus and Ariopsis felis. The VTG
sequences analysis has shown the highest homologous portion of the VTG gene between local H. nemurus with Ariopsis felis
and Bagre marinus. VTG from different species are conserved domains, and phylogenetically related. Studies as such will
certainly provide new insights to better understand the biological role of VTG in river catfish.
