By using PCR cloning techniques, the DNA sequences oi the HMG box regions o
f 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.
