An environmentally induced adaptive (?) insertion event in flax

Genomic changes in flax induced by the environment include the sequences encoding the ribosomal RNAs, many repetitive sequence families and a novel single copy insertion termed LIS-1, comprising a 5.7 kilobase (kb) DNA fragment. The variation in these sequences has been followed in the flax variety Stormont Cirrus under four different growth conditions. LIS-1 was observed to always become both homozygous and inherited...

Associations between prolactin gene polymorphism and milk production in montebeliard cows

Prolactin (PRL) is one of the multi-purpose hormones of the pituitary gland in terms of biological actions especially milk production.  In this study associations were analyzed between polymorphisms of the prolactin gene (PRL-RsaI) and milk production traits of Montebeliard cows. PCR-RFLP method was used for identification of genotypes. Frequencies of genotypes were 0.81, 0.15 and 0.04 for A/A, A/B and B/B,...
