Epichloë Endophyte

Abstract Background: Festuca sinensis is a perennial grass of the genus Festuca, which has strong stress tolerance and high adaptability. F. sinensis normally symbiotic with Epichloë endophyte. In order to evaluate the possibility of F. sinensis-endophyte association as bioremediation grass in heavy metal polluted soils, the effects and mechanism of the F. sinensis-endophyte interaction under heavy metal stress was investigated. Results: The growth performance and physiology variations of F. sinensis with (E+) and without endophyte (E-) were evaluated after they were subjected to Zn2+ and Cd2+ treatments. The results showed that heavy metal treatments had significant effects on plants as the growth indices of plants under Zn2+ and Cd2+ treatments had significant differences compared with plants under control treatment (P<0.05). Zn2+ treatment had positive effects on plants whereas Cd2+ treatment had negative effects. The plants under Cd2+ treatment produced more lolitrem B (P<0.05). Endophyte increased host heavy metal stress tolerance by promoting host growth as the E+ plants had significantly higher plant height, tiller number, root length (P<0.05). Endophyte also promoted host Zn2+ ion absorbing and induced more endogenous hormone production (P<0.05). Conclusions: These results suggested that Epichloë regulated host growth and physiology to improve association tolerance to environmental conditions.

Abstract Anthropogenic activities, such as industrial processes, mining, and agriculture, lead to an increase in heavy metal concentrations in soil, water, and air. Given their stability in the environment, heavy metals are difficult to eliminate and can constitute a human health risk by entering the food chain through uptake by crop plants. An excess of heavy metals is toxic for plants, which have various mechanisms to prevent their accumulation. However, once metals enter the plant, oxidative damage sometimes occurs, which can lead to plant death. Initial production of nitric oxide (NO), which may play a role in plant perception, signalling, and stress acclimation, has been shown to protect against heavy metals. Very little is known about NO-dependent mechanisms downstream from signalling pathways in plant responses to heavy metal stress. In this review, using bioinformatic techniques, we analyse studies of the involvement of NO in plant responses to heavy metal stress, its possible role as a cytoprotective molecule, and its relationship with reactive oxygen species. Some conclusions are drawn and future research perspectives are outlined to further elucidate the signalling mechanisms underlying the role of NO in plant responses to heavy metal stress.
