Placental Lactogen is a polypeptide hormone that is produced by the Placenta, also known as chorionic somatomammotropin hormone. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. The objective of this study was to investigate the bovine Placental Lactogen (bPL) gene polymorphism of Holstein cows in Razavi Khorasan province. Blood samples we...

The Pacific cod ( Gadus macrocephalus ) supports large commercial fisheries in the northern Pacific Ocean and the Bering Sea. Here we characterize 10 polymorphic microsatellite loci isolated from enriched genomic libraries. Loci were screened on a sample of 96 spawning adults. The average number of alleles per locus was 25.3 (range 12–44), with expected heterozygosities ( H E ) ranging from 0.5...

the pituitary-specific transcription factor (pit-1) gene is a candidate gene for growth, carcass and also for milk yield traits. in dairy farm animals, the main goal of the selection is the improvement of milk yield and composition. the genes of milk proteins and hormones are excellent candidate genes for linkage analysis with quantitative trait loci (qtl) because of their biological significan...

Uredinia of poplar leaf rust, Melampsora medusae Thüm f.sp. deltoides, appeared in late July 1998, June 1999, and August 2000 in a cottonwood (Populus deltoides Bartr.) stand in Ames, Iowa. Seedlings of the alternate host (eastern larch, Larix laricina (Du Roi) K. Koch) set out at the site in spring 2000 formed aecia 3 months before uredinia appeared. Using three PCR-based microsatellite marker...

Twelve new polymorphic microsatellite loci were developed for the hard-shelled mussel, Mytilus coruscus. In 32 individuals from a wild population of coastal Zhoushan, Zhejiang Province, China, the number of alleles at these loci varied from 3 to 15, with a mean of 5.667. The mean observed and expected heterozygosities were 0.6927 and 0.6591, respectively. Among these polymorphic microsatellite ...

Cordylophora caspia, a colonial hydrozoan native to the Ponto-Caspian region, has become a common invader of both fresh and brackish water ecosystems of North America and Europe. We describe 11 polymorphic microsatellite loci for this species. Preliminary analyses indicate that population substructure may contribute to departures from Hardy-Weinberg equilibrium. In addition, new loci failed to ...

Sixteen microsatellite loci isolated from Halesia tetraptera are described. All 16 are polymorphic, with four to 13 alleles across 15–19 members of a single half-sib family. Heterozygosity ranged from 0.067 to 1. One locus departs significantly from Hardy–Weinberg equilibrium in our test family. The test population shows significant heterozygote deficiency at this and two other loci. Thirteen l...
