Abstract： The mutually beneficial symbiosis system formed between arbuscular mycorrhizal fungi (AMF) and host plants is one of the representative types of symbiosis systems widely distributed in various ecosystems. In addition to promoting the growth and development of host plant, AMF can also have various effects on the reproduction process of host plants. Studying the changes of reproduction strategies of host plants infected by AMF has important theoretical significance for in-depth understanding of changes in plant reproduction fitness. In this article, we review the related researches on the effects of AMF on the reproduction of host plant, including the effects of AMF infection on reproductive allocation, floral characteristics, insect-pollination and anthesis of host plants. Although current studies have found that AMF can promote the increase of host plant reproduction input, increase the size and number of flowers, increase the number of pollen and nectar secretion, affect the behavior of flower visitors, and cause early flowering and prolonged flowering, the specific mechanism of AMF affecting reproduction of flowering plant is still unclear, and there is currently no unified conclusion due to differences between host plants. However, due to the ubiquity of AMF symbiosis with plant, its important role in the process of plant reproduction cannot be ignored. In the future, more researches should be conducted to investigate the influence mechanism of AMF on the reproductive traits of host plants, the resource allocation of male and female functions in the process of plant sexual reproduction, asexual reproduction and offspring fitness in addition to conducting more in-depth studies in the above-mentioned aspects.
