note = {Twelve genes, BVES, SLC3A2, AHNAK, ZDHHC5, CS, LYZ, KERA, COQ9, UN (a nonannotated EST), EGFR, VTN and ZYX, whose candidacy for traits related to water-holding capacity of meat arises from their trait-dependent differential expression and/or trait correlated expression, were selected for analysis. Based on in silico analysis SNPs were detected, confirmed by sequencing and used for genotyping. For the first eleven genes, the SNPs were genotyped in ca. 1,800 animals from 6 pig populations including commercial herds of Pietrain (PI(a/b)), Pietrain x (German Large White x German Landrace) (PIF1(a/b/c)), and German Landrace (DL(a/b)) and one experimental F2-population Duroc x Pietrain (DUPI). For ZYX, the SNPs were genotyped in 870 animals from 4 pig populations including PI, DL, F1 and PIF1. Comparative and genetic mapping established the location of BVES on SSC1, of SLC3A2, AHNAK and ZDHHC5 on SSC2, of CS, LYZ and KERA on SSC5, of COQ9 on SSC6, of UN on SSC7, of EGFR on SSC9, of VTN on SSC12 and of ZYX on SSC18 respectively, coinciding with QTL regions for carcass and meat quality traits. BVES, SLC3A2, AHNAK, CS, LYZ, UN, VTN and ZYX revealed association with drip loss and also with several other measures of carcass and meat quality traits. KERA was associated with loin eye area and pH. Moreover, several carcass fatness traits and meat quality traits such as meat color and thawing loss were associated with COQ9 and EGFR. However, none of the candidate genes showed a significant association to a particular trait across all populations. This may be due to breed specific effects that are related to the differences in carcass and meat quality of these pig breeds. This study reveals statistic evidence for a link of genetic variation at these loci or close to them with phenotypic variation and promotes those twelve candidate genes as functional and/or positional candidate genes for carcass and meat quality traits.},
