The geographic distribution of flavone-glycosylating genes in Silene pratensis (Rafn.) Godron and Gren. (Caryophyllaceae)

摘要: In Silene pratensis three loci (g, gl and fg) control the glycosylation of isovitexin. Three alleles are known for both g-locus g G X ) gl-locus (gl, gl A R ); fg-locus there only two (fg Fg). The distribution these over 285 European populations S. has been investigated. It was concluded that different chemical races within in Europe. first race contains western southern Europe displays high frequencies , fg. very second race, which can be found USSR, Scandinavia eastern Poland. third occurs central this g high, Fg low to moderate groups. seldom pratensis, but present closely related dioica. They do occur with some possibly as a result hybridization
