title: Polymorphisms for 7 expressed sequence tags showing marbling-associated expression changes.
abstract: We have recently showed that the 7 expressed sequence tags (ESTs), c2-11#2, c3-3, c20-29, c22-3, c26-18#1, c26-42, and g5-10, possess expression differences in musculus longissimus muscle between low-marbled and high-marbled steer groups. In the present study, we detected single nucleotide polymorphisms (SNPs) in the 5' flanking regions of the 7 EST sequences between the 2 steer groups. A SNP for the c2-11#2 EST exhibited significantly different allelic distribution between animals with extremely high predicted breeding value for marbling and with extremely low one. The SNP in the ribosomal protein L27a (RPL27A) gene containing the c2-11#2 EST sequence may be related to changes in gene expression and/or marbling.
