| Research Abstract |
To understand how marsupial male can be genetically determined, we have investigated molecular evolution and function of male determining gene SRY, and identified testis-expressed genes in marsupials by transcriptome analyses. Based on the molecular evolutionary and biochemical analyses, marsupial (wallabies, koalas and so on) SRY sequences are not conserved well compared to eutherian (humans, mice and so on) SRY, but the function of marsupial SRY is similar to eutherians. This study strongly suggests that marsupial male determining gene is also SRY.
