Arbuscular mycorrhizal (AM) fungi are obligate symbiotic endophytes which have not been cultured in vitro. The life cycle of AM fungi can be completed only when the mycorrhiza forms between the fungi and plant roots. There are more than 200 genetically-diverse species of AM fungi belonging to Glomeromycota in the Kingdom Fungi. It is well documented that surprisingly high genetic variability exists between and within species, and even in a single spore of AM fungi. We summarize recent advances in the study of AM fungal diversity, discuss some related problems, and introduce present and future research trends.

Key words: arbuscular mycorrhizal fungi, genetic diversity, gene variance
