An enhanced molecular marker based genetic map of perennial ryegrass (Lolium perenne) reveals comparative relationships with other Poaceae genomes.
TLDR
It is proposed that the linkage groups of perennial ryegrass be numbered in accordance with these syntenic relationships, to correspond to the homoeologous groups of the Triticeae cereals. Expand
Synteny between a major heading-date QTL in perennial ryegrass (Lolium perenne L.) and the Hd3 heading-date locus in rice
TLDR
This syntenic relationship will greatly facilitate the genetic dissection of aspects of heading-date induction by enabling the magnitude of the genetic component of the heading- date QTL in L. perenne to be combined with the sequencing and annotation information from the rice genome. Expand
Physical and genetic mapping in the grasses Lolium perenne and Festuca pratensis.
TLDR
The physical map and genetic map demonstrated that nucleolar organizer regions (NORs) and centromeres greatly reduce recombination, that coding sequences are present close to the centromere and NORs in areas of low recombination in plant species with large genomes; and apparent complete synteny between the F. pratensis chromosome and rice chromosome 1.

TLDR
The draft genome sequence of perennial ryegrass (Lolium perenne), an economically important forage and turf grass species that is widely cultivated in temperate regions worldwide, is reported, and will accelerate the development of new varieties for more productive grasslands. Expand
Genetic analysis of adaptation differences between highland and lowland tropical maize using molecular markers
TLDR
Molecular marker-assisted selection would be an ideal tool for this task, since it could greatly reduce the linkage drag caused by the unintentional transfer of undesirable traits, and pleiotropy is suggested as the main cause for the clustering. Expand
Cross-Species Identification of Mendel's I Locus
A key gene involved in plant senescence, mutations of which partially disable chlorophyll catabolism and confer stay-green leaf and cotyledon phenotypes, has been identified in Pisum sativum,Expand
Dissecting the regulation of fructan metabolism in perennial ryegrass (Lolium perenne) with quantitative trait locus mapping.
TLDR
Quantitative trait locus (QTL) mapping, which can be a useful tool for dissecting complex traits, has been used here to study the regulation of fructan metabolism in temperate forage grasses and the effect of environment. Expand
Integration of gene-based markers in a pearl millet genetic map for identification of candidate genes underlying drought tolerance quantitative trait loci
TLDR
A map based on genes with assigned functional roles in plant adaptation to drought and other abiotic stresses is reported and many of these candidate genes were found to have significant association with QTLs of grain yield, flowering time and leaf rolling under drought stress conditions. Expand
Alignment of the Genomes of Brachypodium distachyon and Temperate Cereals and Grasses Using Bacterial Artificial Chromosome Landing With Fluorescence in Situ Hybridization
TLDR
A BAC library has been constructed for the two diploid genotypes, ABR1 and ABR5, confirming the conservation of genome synteny and proving that B. distachyon has utility as a temperate grass model species alternative to rice. Expand
An association mapping approach to identify flowering time genes in natural populations of Lolium perenne (L.)
TLDR
The results suggest that association mapping approaches may be feasible in L. perenne, and that the use of natural populations could provide a useful source of genetic variation in traits of importance in crop improvement. Expand
