Sox and Zfx genes in giant panda

By using PCR cloning techniques, the DNA sequences of the HMG box regions of six Sox genes ( pSox ) and the zinc finger domains of two Zfx genes ( pZfx ) in the giant panda were identified. The giant panda Sox genes fell into two subfamilies, SOX S1 and SOX S2. The pSox and pZfx genes of the giant panda were highly homologous to the corresponding genes in mammals and revealed close substitution rates to those in the primates.
