چکیده

PoZyrnorphisrn. A multiallelic dinucleotide repeat (CA-microsatellite) polymorphism in genomic DNA of rainbow trout ( Oncorhynchus mykiss Walbaum) was detectable by polymerase chain reaction (PCR) and designated FGT2. Source and Description. Sequence was obtained by conventional dideoxy methods using T7 DNA polymerase. The template was isolated from a library of sizeselected (150 to 400 bp) Sau3AI restriction fragments from the RTG-2 cell line (Wolf and Quimby, 1962) by screening with an end-labeled (CA) 10 oligonucleotide probe. Primers were designed to amplify a region containing the imperfect repeat 5’-(CA)l&A(CA)123’. Method of Detection. Polymerase chain reaction was performed using primers FGT2F: 5’GTGTGGAACCCAACAGGC-3’ (CA strand) and FGTBR: 5’-GAAACACGTCTGGGGTCAGT-3’. Each reaction (25 pL final volume) contained .2 pg of genomic DNA, 20 pmol of each primer, .2 units of Tuq polymerase, 400 kmol of each dNTP, and buffer as

Polymorphism. A variable number of tandem repeat (VNTR; Nakamura et al., 1987) polymorphism was detected in rainbow trout (Oncorhynchus rnykiss Walbaum) using BgZII. The probe, RW9401, was isolated from a genomic DNA cosmid library developed from the RTG-2 cell line (Wolf and Quimby, 1962). Method of Detection. Nylon filters containing rainbow trout genomic DNA digested with BgZII were prehy...

Characterization and comparison of microsatellites derived from repeat-enriched libraries and expressed sequence tags.

The construction of high-density linkage maps for use in identifying loci underlying important traits requires the development of large numbers of polymorphic genetic markers spanning the entire genome at regularly spaced intervals. As part of our efforts to develop markers for rainbow trout (Oncorhynchus mykiss), we performed a comparison of allelic variation between microsatellite markers dev...
