Abstract

A genetic linkage map of the European sea bass (Dicentrarchus labrax) was constructed from 174 microsatellite markers, including 145 new markers reported in this study. The mapping panel was derived from farmed sea bass from the North Adriatic Sea and consisted of a single family including both parents and 50 full-sib progeny (biparental diploids). A total of 162 microsatellites were mapped in 25 linkage groups. Eleven loci represent type I (coding) markers; 2 loci are located within the peptide Y (linkage group 1) and cytochrome P450 aromatase (linkage group 6) genes. The sex-averaged map spans 814.5 cM of the sea bass genome. The female map covers 905.9 cM, whereas the male map covers only 567.4 cM. The constructed map represents the first linkage map of European sea bass, one of the most important aquaculture species in Europe.

“…On the other hand, their generation requires high costs and is time consuming (reviewed in Erickson et al 2004). Most linkage maps based on microsatellites have been constructed for economically important fish species, such as the Atlantic salmon (Gilbey et al 2004), rainbow trout (Sakamoto et al 2000), European sea bass (Chistiakov et al 2005), and Nile tilapia (Kocher et al 1998;Lee et al 2005), to search for loci that affect commercially important traits. Research in the fields of ecology and evolution has recently begun to focus on identifying the genetic basis of adaptive trait evolution especially in natural populations of nonmodel organisms.…”

“…However, an increasing number of linkage maps are now being reported from natural populations of organisms, such as butterflies ( Jiggins et al 2004), fishes (Chistiakov et al 2005), fungi (Marra et al 2004), insects (Lorenzen et al 2005), molluscs (Hubert and Hedgecock 2004), and amphibians (Smith et al 2005). They are so far generally limited to species that can easily be bred in captivity or where sufficiently large litter sizes are being produced in natural settings and are accessible to sampling to allow the establishment of pedigrees necessary for linkage analysis.…”

“…균 류에서의 SSR의 역할에 대한 연구는 몇몇 균주에 대해 한정적으로 연구되었는데 (Karaoglu et al, 2004;Labbé et al, 2011), 느타리버섯 유전체내의 초위성체는 대부분 exon외에 존재하여 유전자 사이의 영역에 존재하는 것으 로 예측되었다 (Qu et al, 2016). 유전체가 복제될 때 다양 한 요인으로 인하여 복제효소의 작용으로 SSR에 돌연변 이가 생길 수 있는데 (Chistiakov et al, 2005), 이때 반복 서열이 더해지거나 빠져나감으로써 SSR의 크기가 달라질 수 있다 (Wei et al, 2015). SSR이 늘어나거나 줄어 드는 것은 유전체 전체의 안정성과 진화와 교차에 영향을 미칠 수 있는 것으로 보고되었다 (Ellegren et al, 2004;Loire et al, 2013).…”
