Abstract (sommario):

Around seven species of the genous lolium poisonous grasses belonging to the family Poaceae are mutually grown in corps field over the world. In Iraq the prennel ryegrass is locally called “rewatta”.The toxicity of these gasses are related to three chemically distinct alkaloids groups; the aminopyrrolizidine; lolines, indole-diterpenes (ergots, loliterms, and paxillines) as well as peramine alkaloids mostly concentrated in their seeds although indole-diterpene alkaloids loliterm B and paxilline biosynthesis requires endophytes symbiosis. The level of loline alkaloids enhances in both late summ

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

Abstract (sommario):

Species of the genus Lolium are important fodder and turf grasses for agricultural and amenity use world-wide. Difficulties currently exist regarding the taxonomy of Lolium species and also in the demarcation between Lolium and the genus Festuca, with the debate focusing on the status of Festuca pratensis and its relations. The diversity in ribosomal DNA (rDNA) in Lolium was investigated. Cloned probes for rDNA, derived from the intergenic spacer (IGS-M) and transcribed regions (COD-M) of mustard (Sinapis alba) were used to investigate species relationships. Genomic DNA from seven Lolium taxa,

Abstract (sommario):

The ryegrass species are visually similar, and therefore, correct identification of short-lived species is very important in breeding work. The aim of the current study was to identify short-lived ryegrass species and subspecies using anatomical and morphological characteristics. The study was carried out at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry (during 2007-2010). The assessment of morphological and anatomical traits showed that average values for species diverged, but values for individual plants often overlapped between species. One of the mos

Although much is known about the beneficial and detrimental effects of the interaction between Neotyphodium lolii and Lolium perenne in the field comparatively little is known about the molecular and cellular events that underlie these effects and how mutualism is maintained. Because N. lolii is quite intractable to genetic analysis we have developed the synthetic association between EpichloÃ« festucae and perennial ryegrass as our model experimental system to study the epichloÃ« endophytegrass symbiotic interaction. Using this system we have recently shown that reactive oxygen species (ROS) p

Abstract (sommario):

Italian (Lolium multiflorum) and short-term hybrid ryegrasses (L. boucheanum) are utilised by farmers for their reliable establishment and yield potential for winter feeding, but lack summer production and persistence. To improve the performance of these ryegrasses, endophyte (Neotyphodium lolii) strains from perennial ryegrass were inoculated into several cultivars and evaluated for agronomic performance in the Northland region of New Zealand. 'Moata' tetraploid Italian ryegrass families usually showed a reduction in yield when infected with the AR5 strain compared with endophyte-free Moata.

The ability of Hordeum glaucum to germinate and initially grow faster than Lolium rigidum was found to be influenced by the soil's physical state and its chemical characteristics. Glasshouse studies showed that the replacement of Lolium by Hordeum in undisturbed situations was due to the advantage of the latter having awned florets which anchor and lever the seed on smooth, compacted surfaces. Soil disturbance produces a broken surface upon which Hordeum has no advantage over Lolium. Hordeum is also able to germinate under higher osmotic pressures than is Lolium.

To perform a sensitivity analysis on Lolium spp. populations in an agriculture area, collection sites were mainly chosen where glyphosate had not been applied intensely.

A pot experiment investigated interactions between foliar endophytic (EP, Neotyphodium lolii) and root arbuscular mycorrhizal (AM, Glomus mosseae) fungi in Lolium perenne. The effects of three phosphorus (P) forms (KH2PO4-P, phosphate rock-P (PR) and phytate-P) on EP and AM colonisation and plant growth parameters were also assessed. AM arbuscular and vesicular structures were estimated by microscopic counting and fungal concentrations were quantified by qPCR of G. mosseae and N. lolii specific genes. Significantly more AM structures were formed in roots of EP-free compared to EP-infected plan

Abstract (sommario):

Strains of perennial ryegrass (Lolium perenne L.) endophyte (Neotyphodium lolii) from nature can be selected by analysis of the alkaloid profiles in plants from diverse seed collections. Lolitrem B, ergovaline, and peramine are the alkaloids of primary interest. The selected endophytes can be cultured and transferred into improved cultivars or breeding lines to reduce or eliminate grazing animal toxicoses while significant plant protection qualities can be maintained. Because the endophytes are transmitted only through seed, stable infections with selected endophytes in pastures can be achieve

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

Wysiane mieszanki składały się z 3 gatunków: Lolium perenne L. (46%), Phleum pratense L. (30%) i Trifolium repens L. (24%). W wyżej wymienionych badaniach uwzględniono 18 odmian Lolium perenne (potraktowanych z pozostałymi komponentami mieszanek jako obiekty badawcze), różniących się pochodzeniem oraz poliploidalnością (odmiany duńskie — Fanda, Pimpernel, Husky, Canasta, Tivoli, Napoleon, Sampo; holenderskie — B

Abstract (sommario):

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

Abstract (sommario):

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. Festuca arundinacea and Phleum pratense showed greater re

Przedstawiono grzyby z rodzaju Neotyphodium żyjące w systemicznej współzależności z głównymi gatunkami traw: N. lolii, z Lolium perenne, N. coenophialum z Festuca arundinacea i N. uncinatum z Festuca pratensis. Opisano ich systematykę, biologię i produkowane alkaloidy. Zwrócono uwagę na korzystne i szkodliwe efekty współżycia traw z endofitami. Przedstawiono wyniki badań dotyczące ich występowania i rozprzestrzenienia na świecie, w Europie i w Polsce. Stwierdzono potrzebę intensyfikacji badań nad endofitami w Polsce. Podano metody wykrywania endofitów w nasionach i roślinach.
