“…Our study further demonstrated that endophyte is capable of enhancing the disease resistance of the host by activating the defense system, and pre-drought treatment is conducive to potentiate the effect of endophyte to some degree. We predict that E. bromicola may make a contribution to the development of a novel, long-term biocontrol strategy for plant protection and agricultural production (Jia et al 2013).…”

Symbiotic relationships with beneficial microbes often increase the resistance of the host grass to abiotic and biotic stresses. In this study, the resistance of endophyte-infected (E+) and endophyte-free (E-) Leymus chinensis to two species of pathogen fungi, Curvularia lunata and Bipolaris sorokiniana, were compared under normal water and pre-drought treatments. The results showed that endophyte infection significantly reduced leaf lesion area of the host grass on one hand, and on the other hand the maximum quantum efficiency of PSII (Fv/Fm) of E+ plants was higher than E-plants, and these advantages of E+ over E-plants were strengthened by pre-drought stress. Predrought treatment led to significantly higher salicylic acid (SA) and lignin accumulation in E+ plants in comparison with E-when exposed to both C. lunata and B. sorokiniana. Additionally, glutamine and phenylalanine concentrations were significantly affected by the interaction between endophyte infection and pathogen inoculation. Overall, endophytes could enhance the pathogen resistance of host by activating a rapid defense reaction of the plant, and this advantage of E+ over Eplants could be strengthened by pre-drought treatment.

“…To date, insect resistance has only been reported for L. chinensis – E. bromicola, A. sibiricum – E. sibirica and A. inebrians – E. gansuensis associations in China. Jia et al ( 2013 ) concluded that L. chinensis – E. bromicola and A. sibiricum – E. sibirica symbioses could diminish the negative effects of infection by Meloidogyne incognita . The researchers used a 72-h exposure to undiluted culture filtrates of the two endophytes and found L. chinensis infected with E. bromicola had an especially strong antagonistic effect on Meloidogyne infection.…”

Epichloë fungal endophytes are broadly found in cool-season grasses. The symbiosis between these grasses and Epichloë may improve the abiotic and biotic resistance of the grass plant, but some Epichloë species produce alkaloids that are toxic for livestock. Therefore, it is important to understand the characteristics of the grass-Epichloë s symbiosis so that the beneficial aspects can be preserved and the toxic effects to livestock can be avoided. Since the 1990s, Chinese researchers have conducted a series of studies on grass-Epichloë symbiosis. In this review, we describe the current state of Epichloë endophyte research in Chinese native grasses. We found that more than 77 species of native grasses in China are associated with Epichloë endophytes. In addition, we review the effects of various Epichloë species on native grass responses to abiotic and biotic stress, phylogeny, and alkaloid production. We provide an overview of the study of Epichloë species on native grasses in China and directions for future research.

“…Mutual relationships have been found between endophytes and some important cultivated grasses such as tall fescue and perennial ryegrass [22][23][24]. The host plants can provide endophytic fungi with photosynthetic products, nutrients and habitats; moreover, secondary metabolites produced by endophytic fungi can promote the growth and development of host plants [25] and improve the host's resistance to biotic [26][27][28][29][30] and abiotic stresses [31][32][33] such as drought [34][35][36], nutrient deficiency [37], herbivory [38][39][40][41] and pathogens [25,42,43], Given the higher growth advantages of endophyte-infected (E+) over endophyte-free (E−) plants, E+ grasses are considered to be ideal plant species for artificial grasslands. However, endophyte infection could change the interspecific relationship between host grasses and neighboring plants [44].…”

The Inhibitory Effect of Endophyte-Infected Tall Fescue on White Clover Can Be Alleviated by Glomus mosseae Instead of Rhizobia

In artificial ecosystems, mixed planting of gramineous and leguminous plants can have obvious advantages and is very common. Due to their improved growth performances and stress tolerance, endophyte-infected grasses are considered to be ideal plant species for grasslands. However, endophytic fungi can inhibit the growth of neighboring nonhost leguminous plants. In this study, we chose endophyte-infected and endophyte-free tall fescue (Lolium arundinaceum Darbyshire ex. Schreb.) and clover (Trifolium repens) as the experimental materials to explore whether arbuscular mycorrhizal fungi and rhizobium can alleviate the inhibitory effect of endophyte infection on clover. The results showed that endophytic fungi significantly reduced clover biomass. Arbuscular mycorrhizal fungi inoculation significantly increased the biomass of clover in both endophyte-infected tall fescue/clover and endophyte-free tall fescue/clover systems but the beneficial contribution of arbuscular mycorrhizal fungi was more obvious in the endophyte-infected tall fescue/clover system. Rhizobia inoculation could alleviate the detrimental effect of tall fescue on the growth of clover but did not alleviate the detrimental effect of endophyte infection on the growth of clover.
