Variation in the KAP8-2 gene affects wool crimp and growth in Chinese Tan sheep. Small Ruminant Research, 149, 77-80. doi:10.1016/j.smallrumres.2017.01.0010921-4488EW2TE (isidoc)https://hdl.handle.net/10182/8753The keratin-associated protein KAP8-2, is present in wool from sheep. The effect of variation in KRTAP8-2 on wool traits was investigated in Chinese Tan sheep. Two previously identified KRTAP8-2 alleles (A and B) were detected, but the frequency of B in the Tan sheep was much higher than reported previously for New Zealand (NZ) sheep. Variant A was found to be associated with both a decrease in straightened fibre-length and the ratio of straightened length to crimped length at day-35 post-partum (conventionally called ‘Er-mao’). A trend was evident between the presence/absence of A and crimped fibre-length at Er-mao, and between the presence/absence of A and fibre growth-rate from birth to Er-mao. This suggests that variation in ovine KRTAP8-2 may affect wool crimping and growth in the early life of Tan sheep.pp.77-80en© 2017 Elsevier B.V.KAP8-2 gene (KRTAP8-2)variationcrimpwool traitsChinese Tan sheepJournal Article10.1016/j.smallrumres.2017.01.0011879-0941ANZSRC::3003 Animal production
