Intrapopulation genome size dynamics in Festuca pallens.

BACKGROUND AND AIMS It is well known that genome size differs among species. However, information on the variation and dynamics of genome size in wild populations and on the early phase of genome size divergence between taxa is currently lacking. Genome size dynamics, heritability and phenotype effects are analysed here in a wild population of Festuca pallens (Poaceae). METHODS Genome size wa...

Exploiting repetitive sequences and BAC clones in Festuca pratensis karyotyping

The Festuca genus is thought to be the most numerous genus of the Poaceae family. One of the most agronomically important forage grasses, Festuca pratensis Huds. is treated as a model plant to study the molecular mechanisms associated with tolerance to winter stresses, including frost. However, the precise mapping of the genes governing stress tolerance in this species is difficult as its karyo...

Differential gene expression in Festuca under heat stress conditions.

Fescues (Festuca sp.) are major cool-season forage and turf grass species around the world. Heat stress is one of the limiting factors in the production of fescues as forage in the southern Great Plains of the US. Heat responsive gene transcripts were cloned by using suppression subtractive hybridization between a heat-tolerant and a heat-sensitive fescue genotype subjected to a slowly increase...

Use of Flow Cytometer in Breeding Festuca X Lolium Hybrids

4-97 ABSTRACT Ploidy in various generic Lolium Festuca progenies were assessed by flow cytometry and compared to conventional chromosome counting. In non-segregating triploid and tetraploid progenies, the cytometer estimated so accurately the level of plant ploidy that chromosomes counting would be no use. In segregant progenies, all the tetraploid plants according to the cytometer had effectiv...
