Transferability, amplification quality, and genome specificity of microsatellites inBrassica carinata and related species

No information is available on the transferability and amplification quality of microsatellite (SSR) markers of the public domain inBrassica carinata A. Braun. The objective of the presented research was to study the amplification of a set of 73 SSRs fromB. nigra (L.) Koch andB. napus L. inB. carinata, and to compare the results with those obtained in the amplification of the same markers in otherBrassica species of the U triangle. This set of SSRs fromB. nigra (B genome) andB. napus (AC genome) allows the identification of the 3 basic genomes of theBrassica species tested. 94.3% of the SSR markers fromB. nigra and 97.4% of those fromB. napus amplified SSR-specific products inB. carinata. Very high-quality amplification with a strong signal and easy scoring inB. carinata was recorded for 52.8% of the specific loci fromB. nigra SSRs and 59.3% of the specific loci fromB. napus SSRs, compared to 66.7% inB. nigra and 62.8% inB. napus. Genome specificity and amplification quality ofB. nigra andB. napus SSR markers in the 6 species under study is reported. High-quality transferable SSR markers provide an efficient and cost-effective platform to advance in molecular research inB. carinata.
