An integrated genomics approach to improving wool productivity and quality

This paper summarises the approach taken in a national research program designed to "identify and utilise genes of importance in the sheep industries". The sheepgenomics program as it was known, comprised meat, wool and parasite subprograms with an underpinning core technology subprogram. The wool subprogram used a combination of gene association and functional biology studies to identify genes and gene networks amenable to manipulation or selection to improve wool production and quality. Significant progress was made in identifying genes involved in wool follicle initiation, hair cycle regulation, recessive black pigmentation and fleece rot. Manipulation of key windows of foetal development resulted in lifetime positive changes in wool production, an important proof of concept in functional, developmental genomics.P. I. Hynd, C. S.
