[Characteristics of fly ash particles deposition in the snowpack of Laohugou Glacier no. 12 in western Qilian Mountains, China].

This research aimed to identify and characterize individual spherical fly ash particles extracted from surface snow at Laohugou Glacier No. 12, western Qilian Mountains, China. Characterization of the spherical particles (i.

[Association analysis between SNPs of the growth hormone receptor gene and growth traits in arctic fox].

Using single-strand conformation polymorphism (PCR-SSCP) and DNA sequencing, single nucleotide polymorphisms (SNPs) of growth hormone receptor (GHR) gene were detected in an arctic fox population. Correlation analysis between GHR polymorphisms and growth traits were carried out using the appropriate model. Four SNPs, G3A in the 5'UTR, C99T in the first exon, T59C and G65A in the fifth exon were identified on the arctic fox GHR gene.

[Correlation analysis between MC3R and MC4R gene polymorphism and growth traits in pigeon.].

The SNPs in partial coding sequence of MC3R and MC4R genes were identified by polymerase chain reaction followed by single strand conformation polymorphism (PCR-SSCP) analysis and DNA sequencing in shack-Kee and Columba domestica from Harbin area. Correlation analysis between MC3R and MC4R polymorphism and growth and body composition traits was carried by the least square analysis. The genotypes of T91G mutation in MC3R gene and A903G mutation in MC4R gene proved to have significant association with body weight, carcass weight, and holo-carcass weight in shack-Kee (P<0.

[Association analysis between SNPs of the growth hormone gene and antler production in spotted deer].

We report the effects of candidate gene growth hormone (GH) gene on antler production in the current study. Single nucleotide polymorphisms (SNPs) of the GH gene were identified and genotyped by polymerase chain reaction followed by single strand conformation polymorphism (PCR-SSCP) analysis and DNA sequencing in a deer population from the farm of Jilin Agricultural University. Correlation analysis between GH polymorphisms and antler production was carried out using the appropriate mixed model.
