abstract = {To reveal genetic diversity for the breed resource evaluation
and utilization of Chinese indigenous donkey, polymorphisms in the third exon
of GH gene was analyzed by PCR-SSCP and DNA sequencing methods in 16
donkey breeds (DZ, GZ, GL, JN, BH, LX, JM, QY, BY, HY, LZ, HB, GY, YY, TH and
XJ). The results showed that there was a transition at nucleotide position 957
genomic DNA of GH gene, named as GH-exon3-G957A which led to a glutamic
acid to lysine substitution at amino acid position 81. Two different alleles,
A and B were identified and three genotypes were observed, AA, AB and BB with
the frequency distribution of allele A from 0.6667-0.8333 in the analyzed populations.
The genetic diversity analysis revealed that PIC values were between 0.346 and
0.491 except JM donkey (0.239), implying that this locus within GH gene
possessed a moderate genetic diversity in Chinese indigenous donkeys. The χ2-test
showed that LX, GY and TH donkeys were no significant deviation, GZ, JN, QY,
HB and XJ donkey were significant deviation, DZ, GL, BH, JM, BY, HY, LZ and
YY donkey were very significant deviation. The results confirmed that there
were polymorphisms in the third exon of GH gene for the first time.}
