Effects of arbuscular mycorrhizal fungi colonization on reed under two water levels
1 Introduction Wetlands are often considered sinks for contaminants including heavy metals and organic pollutant. Phytoremediation is one of the most widely used approaches of removal and clean-up these contaminations. However, utilization of phytoremediation in contaminated area is limited sometimes because some plants have low contaminationtolerance and the contamination in shoots may enter the food webs through herbivores. In order to solve this problem, we found that there is a kind of microorganisms called arbuscular mycorrhizal(AM) fungi which can improve plant tolerance and decrease the content of contaminations in shoots by immobilizing them in the roots and enhance the plant growth with its special tree-shaped subcellular structures. Over the last two and a half decades, the presence of AM Fungi in wetland plants has received increased attention, and there is a number of researches on investigating AM Fungi in marshy plants including reed which is the dominant species in wetlands. However, little is known on AM Fungi colonization of reed in the pot experiment and the effects of AM Fungi on reed. Accordingly, our study focus on whether AM fungi can colonize reed (Phragmites australis) in pot and this is the first report of arbuscular mycorrhizal colonisation of Phragmites australis in greenhouse experiment.
