Summary: This study explored the effects of an Epichloe endophyte on growth and physiology parameters of drunken horse grass under different soil water contents, and examined the possible transgenerational effects on these indicators. The endophyte increased aboveground biomass and chlorophyll content, as well as photosynthetic parameters. It also promoted abscisic acid and indolE-3-acetic acid content but decreased cytokinin content. The nitrogen and phosphorus content of Epichloe-infected plants was higher, but the endophyte decreased C:N and C:P ratios under drought conditions. Transgenerational effects were present, indicating that plants from seeds in dry sites are more competitive under water deficiency conditions.

Summary: This study found that E. gansusensis endophyte increased root-associated AM fungal diversity under drought conditions, while decreasing diversity under water addition treatment. Aboveground biomass was closely related to the abundance of Funneliformis in the root, and soil nitrogen and phosphorus were positively related to the diversity of the rhizosphere soil AM fungal community.

Summary: This experiment investigated the effects of endophytes on the diversity effects of the host plant community biomass. The results showed that endophyte infection significantly increased belowground biomass and the abundance of Cleistogenes squarrosa, as well as the community diversity of the 4-species mixtures. Endophyte infection may contribute to the positive relationship between species diversity and productivity.

Summary: The study focused on the contact toxicity of aqueous extracts of endophyte-infected and endophyte-free plants of Achnatherum inebrians on pea aphids, showing that compounds in endophyte-containing plants may be used to control insects. Different growth periods of endophyte-infected plants had varying effects on pea aphid survival and growth, with extracts from plants at the seeding stage showing the greatest negative impact on aphids.

Summary: Epichloe endophytes can enhance host grasses' resistance to pathogenic fungi by increasing photosynthesis, scavenging reactive oxygen species, and regulating gene expression related to disease resistance. Endophyte infection also induces the accumulation of jasmonic acid, ethylene, and pipecolic acid, strengthening the host's defense response to pathogens.
