Two novel SNPs of the 3-hydroxy-3-methylglutaryl coenzyme A reductase gene associated with growth and meat quality traits in the chicken

Y. Wei, Zhu, S. K., Zhang, S., Han, R. L., Tian, Y. D., Sun, G. R., and Kang, X. T., Two novel SNPs of the 3-hydroxy-3-methylglutaryl coenzyme A reductase gene associated with growth and meat quality traits in the chicken, vol. 11, pp. 4765-4774, 2012.

The enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) is rate-limiting for metabolism of cholesterol; it plays an important role in endogenous cholesterol biosynthesis. We used DNA sequencing technology and created restriction site PCR-RFLP to detect HMGCR SNPs in an F2 resource population of Gushi chicken and Anka broilers. We found a G/T mutation (Gln/His) in exon 17 and a T/C mutation (Pro/Pro) in exon 18.

Mapping of major quantitative trait loci for economic traits of silkworm cocoon

Z. Lie, Cheng, L., Fang-yin, D., and Shou-min, F., Mapping of major quantitative trait loci for economic traits of silkworm cocoon, vol. 9, pp. 78-88, 2010.

The quantitative trait loci (QTLs) associated with cocoon traits in silkworms were mapped in 44 individuals of a backcross of Dazao females with hybrid F1 males; the hybrid males were from females of inbred C100 strain, which have white cocoons and superior cocoon traits, crossed with males of inbred strain Dazao, which have green cocoons and inferior cocoon traits.
