Physical and genetic mapping in the grasses Lolium perenne and Festuca pratensis.
A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. In this line recombination occurs throughout the length of the F. pratensis/L. perenne bivalent. The F. pratensis chromosome and recombinants between it and its L. perenne homeologue can be visualized using genomic in situ hybridizat...
متن کاملAlien introgression in the grasses Lolium perenne (perennial ryegrass) and Festuca pratensis (meadow fescue): the development of seven monosomic substitution lines and their molecular and cytological characterization.
BACKGROUND AND AIMS To address the issues associated with food security, environmental change and bioenergy in the context of crop plants, the production, identification and evaluation of novel plant phenotypes is fundamental. One of the major routes to this end will be wide hybridization and introgression breeding. The transfer of chromosomes and chromosome segments between related species (ch...
متن کاملComparison of early development of three grasses: Lolium perenne, Agrostis stolonifera and Poa pratensis.
BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...
متن کاملMolecular tagging of a senescence gene by introgression mapping of a stay-green mutation from Festuca pratensis.
* Intergeneric hybrids between Lolium multiflorum and Festuca pratensis (Lm/Fp) and their derivatives exhibit a unique combination of genetic and cytogenetic characteristics: chromosomes undergo a high frequency of homoeologous recombination at meiosis; the chromosomes of the two species can easily be discriminated by genomic in situ hybridization (GISH); recombination occurs along the entire l...
متن کاملGenetic Similarities Among Iranian Populations of Festuca, Lolium, Bromus and Agropyron Using Amplified Fragments Length Polymorphism (AFLP) Markers
The study of genetic variation and phylogenetic relationships is essential for the efficient selection of superior plant material and conducting introgression breeding programs. In Iran, despite the wide geographical distribution of grasses no report is available on the genetic diversity and relationships of cool season grass populations. In this study amplified fragment length polymorphism (AF...
