Application of functional genomic information to develop efficient EST-SSRs for the chicken (Gallus gallus)
2012
Many years of domestication and breeding have given rise to the wide range of chicken breeds that exist today; however, an increasing number of local chicken breeds are under threat of extinction. A comprehensive characterization of chicken markers (especially type I markers) is needed to monitor and conserve genetic diversity in this species. The explosion of genomics and functional genomics information in recent years has opened new possibilities for the generation of molecular markers. We analyzed a large number of expressed sequence tags (ESTs) to test the possibility of using EST-derived microsatellite markers for investigating the Gallus gallus genome. Chromosomal locations for the majority of these SSRs were predicted. Of the 31,576 unigenes assembled from the 544,150 redundant EST sequences, 1757
