Leymus chinensis

Taking Leymus chinensis in the Songnen grassland as the research object, this study used high-throughput sequencing technology to analyze the effects of grazing on the community composition and diversity of endophytes (bacteria and fungi) in Leymus chinensis.

Leymus chinensis

In this study, 483 strains of endophytic fungi (belonging to 2 phyla, 35 genera and 42 species) were isolated and identified from the roots of three species of grasses. Among them, the endophytic fungi of Leymus chinensis had the highest diversity, with Fusarium as the dominant genus. Inoculation experiments showed that the arbuscular mycorrhizal (AM) fungus GM1A and the endophytic fungus LC-R-311 of Leymus chinensis significantly promoted the growth of maize and enhanced its stress resistance. This study provides a basis for the utilization of endophytic fungal resources of grassland grasses.

Leymus chinensis

This study took Leymus chinensis infected with endophytic fungi as the material, and explored the effect of endophytic fungi on the disease resistance of the host Leymus chinensis through in vitro pure culture, detached leaf and in vivo plant experiments.

Leymus chinensis

Taking Leymus chinensis in Inner Mongolia as the research object, the study found that the main endophytic fungus is Epichloë bromicola (accounting for 72.4%–91.2% in Abag Banner). It has drought resistance and antibacterial activity (the antibacterial rate is 30–60%), and high water and fertilizer can induce the formation of stroma. A system with or without the fungus can be constructed by using a low concentration of propiconazole, which provides a basis for forage improvement.

Taking Leymus chinensis in the Hulunbuir grassland as the research object, this study systematically analyzes the diversity, distribution patterns and antibacterial activities of its endophytic fungi, aiming to reveal the interaction relationship between Leymus chinensis and endophytic fungi.

Aegilops triuncialis

This study investigated the endophytic fungi in the seeds of wheat and its related species (Triticum boeoticum and Aegilops triuncialis) in the western and northwestern provinces of Iran. Based on morphological characteristics and multi-gene sequence analysis, two new genera and one new species of Sphaeriaceae were discovered and described, and their taxonomic positions were clarified.

Secale cereale

Rye infected with the endophytic fungus Epichloë produces loline alkaloids. Through insect feeding experiments, it has been found that the loline in rye may be transported to the xylem and it is difficult for the alkaloids to have an effect on aphids.

Secale cereale

The phyllosphere microbiome of various cereal crops, including rye, has been studied, and it has been found that the host genotype significantly affects the structure of the fungal community in the phyllosphere of cereals.
