Lolium perenne L. commonly known as “ray grass” is a temperate grass species commonly used as pasture for livestock. Lolium perennen belongs to family Poaceae and is a perennial herb. It has great economic importance owing to its suitability as a forage grass. Lolium perenne is cultivated in fields for forage grass to feed livestock. However, current study focuses on Lolium perenne as uncultivated forage grass. Ray grass is widely distributed in cultivated and uncultivated fields, mostly found in moist places, banks of stream, pastures etc. Farmers benefit from the uncultivated growth of ray g

Fungal endophytes (Neotyphodium lolii) in perennial ryegrass (Lolium perenne) produce a range of bioactive alkaloids which are implicated in both toxicity to grazing animals and resistance to insects. The understanding of regulatory and biochemical mechanisms of the symbiosis will provide clues for the genetic manipulation of beneficial alkaloid production. This paper presents approaches to analyse data from high-throughput microarray experiments and targeted metabolomic analyses.

Two are pathogenesis-related PR-10 proteins, part of a ubiquitous plant response to pathogens. We have identified seven different L. perenne PR-10 genes and found that endophyte infection increases PR-10 transcript levels, but only mildly. Furthermore, PR-10 mRNA levels also increase in a dysfunctional symbiosis, but the two identified PR-10 proteins are absent.

Abstract 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). The chromatin of F. pratensis and L. perenne can be distinguished by genomic in situ hybridization (GISH), and it is therefore possible to visualize the substituted F. pratensis chromosome in the L. perenne background and to study chiasma formation in a single marked bivalent. Recombination occurs freely in the F. pratensis/L. perenne bivalent, and chiasma frequency counts give a predicted map length for this bivalent of

To investigate the interaction between Argentine stem weevil (Listronotus bonariensis), its parasitoid Microctonus hyperodae, fungal endophyte (Neotyphodium lolii) and its grass host, four endophyte-ryegrass (Lolium perenne) treatments were established on four farms in Wairarapa in autumn 2003. A diploid ryegrass contained either wild-type or AR1 endophyte or was endophytefree, while a tetraploid ryegrass contained AR1 endophyte. Wild-type, AR1 and endophyte-free ryegrasses average 52%, 91% and 2% endophyte-infected tillers for the 3 years of measurement. Moderate increases over time in the pr

Festuca arundinacea had few primordia, a large length of apex per primordium, and apices which were well below ground or near ground level.

One-week-old seedlings of inbred lines of perennial ryegrass (Lolium perenne L.) were given a 3-h period of treatment with 0.2% colchicine, and this treatment was found to have heritable effects on chromosome behaviour at meiosis. The mean pollen mother cell chiasma frequency was reduced, and there was a corresponding increase in the number of univalents per cell and also changes in cell and bivalent variances. Patterns of chiasma distribution within bivalents were also modified. The effects were seen in the generation in which the treatment was given and they were also observed in the followi

However, there has been conflicting findings on the use of mixed plant community.

Perennial ryegrass (Lolium perenne) is the most cultivated cool-season grass worldwide with crucial roles in carbon fixation, turfgrass applications, and fodder for livestock. Lolium perenne forms a mutualism with the strictly vertically transmitted fungal endophyte, Epichloë festucae var lolii. The fungus produces alkaloids that protect the grass from herbivory, as well as conferring protection from drought and nutrient stress. The rising concentration of atmospheric CO2, a proximate cause of climatic change, is known to have many direct and indirect effects on plant growth. There is keen int

Each pair of primers resulted in the amplification of large number of AFLP fragments. Most fragments were polymorphic and many of them were restricted to a single species.

These wild-type endophyte strains may be toxic to domestic livestock. Sources are from seed (natural reseeding, buried seed, sown seed, in dung, hay, carried on farm machinery) and survival of existing infected ryegrass plants. In particular, seed in soil and dung are reviewed. Contamination may occur both pre- and postestablishment.
