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.
A changing climate for grassland research.
TLDR
Sustainability traits discussed here include stress resistance, cold and pathogeneses, and favourable agronomic characters (nutrient use efficiency, carbohydrate content, fatty acid content, winter survival, flowering time and biomass yield) and global warming will predictably affect temperature-sensitive traits such as vernalisation, and these traits are under investigation.
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.
Comparison and integration of genetic maps generated from F2 and BC1‐type mapping populations in perennial ryegrass
TLDR
Comparison and integration of genetic maps generated from F2 and BC1-type mapping populations in perennial ryegrass populations in Lolium perenne L.
Identification and mode of action of self-compatibility loci in Lolium perenne L.
TLDR
It is shown that the T locus, a relic of a multilocus system, functions through interaction with the S locus: F2 segregation of incompatibility phenotypes and linked markers demonstrated that the S/t pollen genotype combination, expected to be compatible on selfing, was sometimes incompatible.
Identifying genetic components controlling fertility in the outcrossing grass species perennial ryegrass (Lolium perenne) by quantitative trait loci analysis and comparative genetics.
TLDR
The identification of QTLs associated with seed set, a major component of seed yield in perennial ryegrass, indicates that mutational load associated with these genomic regions can be mitigated through marker-assisted selection.
Does fructan have a functional role in physiological traits? Investigation by quantitative trait locus mapping.
* The role of fructan in growth and drought-stress responses of perennial ryegrass (Lolium perenne) was investigated in an F(2) mapping family that segregates for carbohydrate metabolism. * A
Expressed sequence tag-derived microsatellite markers of perennial ryegrass (Lolium perenne L.)
TLDR
464 EST-derived SSR primer sequences of perennial ryegrass established in laboratory assays are reported on, providing a dedicated tool for marker assisted breeding and comparative mapping within and among forage and turf grasses.
Quantitative trait loci for leaf length in perennial ryegrass (Lolium perenne L.)
TLDR
Quantitative trait loci for leaf length in perennial ryegrass (Lolium perenne L.) and Grass and Forage Science, 64, 310-321.
Identification of perennial ryegrass (Lolium perenne (L.)) and meadow fescue (Festuca pratensis (Huds.)) candidate orthologous sequences to the rice Hd1(Se1) and barley HvCO1 CONSTANS-like genes
TLDR
Microsynteny with rice and comparative genetic mapping were used to identify candidate orthologous sequences to the rice Hd1(Se1) gene in Lolium perenne and Festuca pratensis, indicating they were CONSTANS-like zinc finger proteins with 61-62% sequence identity with rice HD1 and 72% identity with barley HvCO1.
