Flax is grown for seeds in many countries. Depending on the ratio of fatty acids, seeds are used in pharmaceutical, food, feed, or polymer production. It is known that genes of FAD3 family responsible for the desaturation of linoleic (LIO) into linolenic (LIN) fatty acid and some alleles of these genes are associated with a certain composition of flax oil. However, the development of the marker-assisted selection of flax is complicated due to a lack of methods for the identification of these polymorphisms. In the present study, we used 84 flax cultivars/lines with diverse content of LIO and LIN to search for fatty acid associated SNPs and then developed HRM-based system for identification of these SNPs that can increase the efficiency of breeding by obtaining pure improved cultivars with the targeted LIO and LIN content.
Did anybody use your test system for the identification of the three SNPs in FAD3 genes?
Dear Dr. Lavrekha,
Thank you for your question and sorry for the late response!
At present, the test-system is used in our joint research with the Institute for Flax (Torzhok, Russia). We are planning its wider application after the publication of the results.
Best regards,
Liubov
