Abstract

BENAVIDES, M.V.; DAMAK, S.  and  MAHER, A.P.. A putative resistant DNA marker for wool yellowing susceptibility in sheep. Genet. Mol. Biol. [online]. 2000, vol.23, n.2, pp.341-346. ISSN 1415-4757.  https://doi.org/10.1590/S1415-47572000000200017.

An Australian Merino flock was screened for low (resistant) and high (susceptible) yellow predictive colour (YPC) breeding values in order to compare extreme individuals using the differential display of mRNA technique. One differentially expressed cDNA band was visualised only in the resistant group. This band showed no identity with the DNA sequences of public databases; however, they showed short homologies with three database sequences related to transmembrane signalling functions. The use of these candidate genes as DNA markers needs to be confirmed against sheep with a wide range of susceptibility to wool yellowing to verify the results.
