Abstract (sommario):

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

Abstract (sommario):

In order to make use of the under-forest economy, Lolium perenne were interplanted under the trees, and the effect of coarse fodder processing on the nutrient content of under-forest interplanting Lolium perenne was analyzed. The result showed that the contents of calcium and phosphorus of under-forest interplanting Lolium perenne were 0.79% and 0.119%, while those of forage blocks processed were 0.82% and 0.115%, and the one starch-added were 0.74% and 0.125%, respectively. The calcium contents were 0.51%, 0.67% and 0.76% when the ratio of Lolium multiflorum/ Illicium verum were 100:1, 200:1

Abstract (sommario):

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. Combined with bioinformatics analyses, potential genes were found associated with the accumulation of alkaloids an

Meadows on organic soils perform an essential role as a source of fodder and biomass for energy purposes. In the case of intensive meadows, it is crucial to use grass mixtures that enable obtaining high yields of good quality; however, on organic soils, the grass species composition changes dynamically. We carried out the full cultivation (ploughing) for grassland restoration. The floristic composition of meadow sward in the first year of full use (2013) was similar to the composition of mixtures used for sowing (2012) individual plots.

Abstract (sommario):

We have identified three proteins specifically expressed during the interaction between N. lolii and L. perenne in natural compatible associations. 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. This suggests that part of the regulation of protein expression is at the level of tran

Yield increases are a result of increased harvest index and better dry matter partitioning to the harvested parts. The resulting changes in harvest components include increasing seed head density and seeds per spikelet (better seed retention) associated with delayed lodging.

Abstract (sommario):

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

Abstract (sommario):

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

Two controlled environment experiments were performed to test the effects of nitrogen, phosphorus and carbohydrates on endophyte (Neotyphodium lolii) and alkaloid concentrations in ryegrass (Lolium perenne). Three perennial ryegrass cultivars ('high sugar grasses' AberDove and AberDart; control Fennema) that differ in carbohydrate content were infected with three strains of N. lolii (common strain, CS; AR1; AR37). Infected and uninfected plants were grown under high (9 mM) and low (2.25 mM) nitrogen (AberDove, Fennema; CS, AR1, AR37) or under high (2 mM KH2PO4) and low (0.05 mM KH2PO4) phospho

Abstract (sommario):

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

The use of mixed plant communities has been proposed to address phytotoxicity while improving plant stress tolerance and contaminant degradation. However, there has been conflicting findings on the use of mixed plant community.

This involved greenhouse experiment with Medicago sativa, Festuca arundinacea, and Lolium perenne and Medicago sativa + Lolium perenne with the diesel-spiked soils at 102,000, 151,000 and 320,000 µg kg-1 TPH represented as Treatments 1, 2

Abstract (sommario):

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. Only 10 fragments were monomorphic across all species tested. The

This paper reviews how new pastures may become contaminated with perennial ryegrass (Lolium perenne) infected with wild-type fungal endophytes (Neotyphodium lolii). 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. It is recommended that steps should be taken to minimise contamination from all sources when establ
