A set of tetra-nucleotide core motif SSR markers for efficient identification of potato (Solanum tuberosum) cultivars
نویسندگان
چکیده
Simple sequence repeat (SSR) is a popular tool for individual fingerprinting. The long-core motif (e.g. tetra-, penta-, and hexa-nucleotide) simple sequence repeats (SSRs) are preferred because they make it easier to separate and distinguish neighbor alleles. In the present study, a new set of 8 tetra-nucleotide SSRs in potato (Solanum tuberosum) is reported. By using these 8 markers, 72 out of 76 cultivars obtained from Japan and the United States were clearly discriminated, while two pairs, both of which arose from natural variation, showed identical profiles. The combined probability of identity between two random cultivars for the set of 8 SSR markers was estimated to be 1.10 × 10-8, confirming the usefulness of the proposed SSR markers for fingerprinting analyses of potato.

Microsatellites, or simple sequence repeats (SSRs), especially those with long-core motifs (tri-, tetra-, penta-, and hexa-nucleotide) represent an excellent tool for DNA fingerprinting. SSRs with long-core motifs are preferred since neighbor alleles are more easily separated and identified from each other, which render the interpretation of electropherograms and the true alleles more reliable....

We analyzed a set of twenty most grown potato (Solanum tuberosum L.) varieties listed in the Czech Variety List using the PCR-IRAP (Inter-Retrotransposon Amplified Polymorphism) method in order to distinguish fast and unambiguously the varieties. In total, 62 polymorphic alleles were amplified using the three primers P-Tst-1, P-Tst-3 and P-Tst-6. The recorded pattern of markers was stable and r...

The genetic basis of quantitative disease resistance has been studied in crops for several decades as an alternative to R gene mediated resistance. The most important disease in the potato crop is late blight, caused by the oomycete Phytophthora infestans. Quantitative disease resistance (QDR), as any other quantitative trait in plants, can be genetically mapped to understand the genetic archit...

Optimization of mineral nutrition in aeroponic systems is one of the most significant factors in producing high-quality and high yields of healthy seed tubers in potato (Solanum tuberosum L.). The present study was conducted at the Research Farm and Greenhouse of Agricultural and Natural Resources Center of Ardabil during two successive years (2018-2019). For the aeroponic system an experiment ...
