Abstract | |||||||||||||
| Four experiments aimed at creating wool fibres with improved qualities through sheep transgenesis are described. Attempts were made to increase expression of cysteine-rich proteins in the cortex, increase isopeptide cross-links in the cortex, increase glycine/tyrosine-rich proteins in the cortex, and increase the proportion of intermediate filaments in the cortex. No improvement was observed in either the intrinsic strength or elasticity of the wool fibres. However, the markedly different profiles in the load extension curves suggests further analyses of wool fibres of transgenics. These analyses will determine the exact effect of manipulations upon the intermolecular chemistry of the fibre cortex. | |||||||||||||
