Abstract

Abstract: Grass Epichloë endophyte is a microorganism community with abundant biodiversity; it has become one of the most popular research topics, because of its ecological and physiological functions and the great application potentiality in the fields of agriculture and medicine as biocontrol agents and foreign gene carrier at home and abroad. In this review, the diversity of endophytic fungi in grasses have been summarized, mainly cool-season grasses infected with these endophytes mostly belong to Clavicipitaceae genera of Epichloë (anamorph Neotyphodium). It mainly included the diversities of fungal species, symbiotic host, habitat, morphology and genetics. Eco-environmental complex and abundant plant biodiversity lead rich diversity of endophytic fungi, and more and more new endophyte taxa should be discovered. This is more likely that has unique advantages in the collection and preservation of new fungi. Endophyte could improve the stress tolerance of host grass, make grass to be adapted under stressed even extreme environmental conditions. It has great significance to study deeply on interactions between plant and endophyte, and to build novel symbiosis and the micro-ecosystem of plants.
