Abstract:Endophytes and their host grasses are mutually symbiotic. On one hand, the grasses provide photosynthates for the fungi; on the other hand, the endophytes may enhance the host’s growth and protect the host from biotic stresses (such as mammalian, insect, and nematode herbivores) and abiotic stresses (such as drought and high temperature). In the past, much research work has been done on the beneficial effect of endophyte infection on biotic stress resistance of grasses. When abiotic stress, such as drought...
