Hiroshi Shinozuka, Melanie L. Hand, Noel O. I. Cogan, German C. Spangenberg and John W. Forster Nucleotide diversity of vernalization and flowering-time-related genes in a germplasm collection of meadow fescue (Festuca pratensis Huds. syn. Lolium pratense (Huds.) Darbysh.) Ecology and Evolution 3
Meadow fescue is an important temperate pasture grass. Nucleotide sequence diversity has been determined in genes controlling induction of reproductive development. The resulting haplotype diversity data has been compared with ecogeographical variation within a comprehensive germplasm collection, and the frequencies of differing allelic variants correlated with latitudinal origin for populations distributed across Western Eurasia. Significant differences between populations are interpreted in terms of selection pressures acting on various components of the floral induction system.
