BookPublisher: 2011Subject(s): Institute of Biochemistry & BiotechnologyDDC classification: 1373,T Dissertation note: In farm animals, the primary focus of selection has been to improve milk yield. Milk field is a polygenic trait and a few potential candidate genes have been recognized.
Association studies have shown that POUlFl is related to many production traits in
domestic animals and is one of those candidate genes that are involved in milk
production. POUl F 1 encodes a pituitary-specific transcription factor. It is well
established that growth hormone (GH) released from pituitary gland plays an essential
role in growth, mammary gland development and lactation process. The bovine
POUlFl gene is of 15952 bp length having 6 exons. The genetic characterization of
the POUlFl gene to identify the SNPs as genetic markers and validation of these
potential markers by associating them with milk production traits has been performed.
A total 35 samples from Sahiwal and 30 from Holstein-Friesian cattle breeds were
sequenced for all 6 exonic portions of the POUlFl by using 6 sets of primers. A total
15 polymorphic sites in Sahiwal and 14 in Holstein-Friesian were identified from
these sequences. Out of total 15 SNPs identified in Sahiwal, 12 were in intronic
region and 3 were in exonic. Out of 14 SNPs identified in Holstein-Friesian, 10 were
in intronic and 4 were in exonic region. The sequences of the amplified POUl F 1 gene
fragments were aligned with the help of BLAST for SNPs identification. This study is
first step in finding some confirmed markers for milk yield in Sahiwal and Holstein-
Friesian cattle breed that can be used in future for selection and breeding programmes.
