摘要: We developed molecular markers for discrimination of white and blue flower color in Japanese gentian plants. White-flowered gentians can be classified into two types, based on genetic physiological features. One type includes four allelic variations (gtmyb3-1, gtmyb3-2, gtmyb3-3, gtmyb3-4) an anthocyanin biosynthetic regulator gene (GtMYB3), distinguished by three PCR-based markers. The other contains a newly identified inactive allele (ans1) the anthocyanidin synthase (ANS) with premature stop codon generated from 4-bp deletion second exon. ans1 was active ANS cleaved amplified polymorphism sequence (CAPS) marker. genotypes 12 white-flowered cultivars/lines could as either or gtmyb3 using these No contained alleles simultaneously. mutated co-segregated F2 population, demonstrating that CAPS marker is useful to discriminate between flowers gentian. Markers will early selection progeny breeding management.
