“…Endophyte colonization promoted Cd 2+ ion accumulation in tall fescue (Ren et al 2011 ) and also improved Cd 2+ transport from the root to the shoot. Hesse et al ( 2003 , 2004 ) have also found higher abundances of infected perennial ryegrass genotypes on dry sites compared to wet sites and this has been confirmed in our previous research (Żurek et al 2013 , 2017 ). An abundance of endophyte-infected perennial ryegrass plants was significantly and negatively correlated with annual as well as winter precipitation (multi-annual averages, 1950–2000) at localities of their origin.…”

“…Mentioned ‘variation’ should be ascribed to the natural variation between host (perennial ryegrass), fungus and to their interaction. Spatial variation of mutualistic interactions between a host organism (grass plant) and infecting fungus (endophyte) through its intensity (endophyte frequency per locality) and production of toxic metabolite, i.e., ergovaline, has been previously described (Żurek et al 2013 , 2017 ).…”

Different response of perennial ryegrass—Epichloë endophyte symbiota to the elevated concentration of heavy metals in soil

et al. 2021

The phenomenon of plant mutualistic symbiosis with microbes may have a positive effect on the improvement of plant tolerance to environmental stresses as well as on the ability of plants to accumulate heavy metal (HM) ions from soil. The influence of Epichloë fungal endophyte (Ascomycota, Clavicipitaceae) on perennial ryegrass (Lolium perenne L.) plants grown in the presence of elevated concentrations of HM ions (Cd2+, Pb2+, and Cu2+) in soil was studied. The presence of Epichloë in the host grass tissues resulted in different accumulation of HM ions in the aboveground parts of the plants. In some cases, endophyte infection positively affected ryegrass ability to accumulate HM ions from soil. In plants with (E +) and without (E −) endophytes, the hormesis effect was induced by the elevated concentration of Cu2+ ions, resulting in better growth and photosynthesis, as examined by measurements of Chl a fluorescence. The obtained results indicate that based on the laboratory evaluation of the efficiency of HM accumulation, we were able to choose the best associations of perennial ryegrass with endophytes for HM phytoremediation.

“…The highest endophyte presence in collected ecotypes was noted in populations from the Świętokrzyskie region (78.6%), whereas the lower in the Podlaskie and Mazowieckie regions (56.2% and 43.7%, respectively) ( Table 1 ). Regional differences in the endophytic infections of perennial ryegrass might be due to different climatic conditions, which favour development of endophytes [ 37 , 38 ]. Lewis [ 39 ] reported that in many cases in Europe, the incidence of endophytes in wild populations of L. perenne was high.…”

Is the Vertical Transmission of Neotyphodium lolii in Perennial Ryegrass the Only Possible Way to the Spread of Endophytes?

2015

Endophytic fungi live their whole life within host tissues usually without any visible symptoms. Their vertical transmission (seed-plant-seed) has been well described and documented. However, horizontal transmission (plant-plant) needs more clarification. The aim of this study was to assess the extent to which endophytes move vertically in ecotypes of perennial ryegrass and whether there is evidence for the horizontal transmission of endophytes. Ecotypes from grasslands in Poland were collected in the form of living plants and used for vertical transmission analysis. Plants, the seed collected from these plants and plants grown from this collected seed were tested for endophytic infection. Provided that all produced seeds were viable and able to germinate and produce seedlings, the vertical transmission of Neotyphodium endophytes in perennial ryegrass ecotypes was nearly complete. For the horizontal transmission experiment, endophyte-hosting plants (E+) and endophyte-free plants (E-) of four cultivars were planted in the field in close proximity on small plots that were frequently mown. These studies revealed that after 7 months of growth next to E+ plants, the characteristic Neotyphodium spp. mycelia were found in E- plants, which was especially true for plants growing in close proximity to the infected plants. The occurrence of horizontal transmission of endophytes has not been previously demonstrated.

“…This is due to specific adaptive properties, resulting in efficient dispersal, rapid population growth, resistance to disturbances, phenotypic plasticity, and the ability to transform the environment to its advantage. In addition, increasing the existing resistance of these plants to abiotic and biotic stresses by using their symbiosis with endophytes will increase their adaptability in areas with different thermal and precipitation conditions [129]. All this information indicates the legitimacy of further research on this group of plants because the knowledge of physiological or genetic changes occurring during the adaptation processes to changing environmental conditions, along with proper phenotypic selection, will allow for their use in the breeding process.…”

This article presents perennial grasses, without whose presence it is impossible to imagine the natural environment as well as agriculture, recreation, sport, and satisfactory aesthetics of the environment. Grasses have by far the widest distribution of all flowering families, grow on every continent, and are part of all the major biomes of the terrestrial world. They not only occur in almost all types of natural landscapes but also find a prominent place in the agricultural landscape. Grasses are not only a source of food for people (wheat, rice, maize, millet, etc.) and feed for livestock, but also a source of energy, building materials, a component of paper pulp, etc. Moreover, grasses have numerous uses to enhance the beauty of the surrounding landscape, bring relaxation, health, and comfort to people (i.e., gardens, parks, and sports facilities), and support land protection. This article describes just these, not often mentioned, and characterized grass uses, with an emphasis on the relationship between different species of perennial grasses and their functionality. The aim is to show the various aspects of the amenity use of grasses in the context of species diversity and their future under the conditions of a changing climate.
