[摘要]：Association between arbuscular mycorrhizal fungi (AMF) and majority of terrestrial plant species provides many benefits to plants that range from stress alleviation and bioremediation in soils polluted with heavy metals to plant growth promotion and yield quantity. Some non-arbuscular mycorrhizal fungi such as. Trichoderma harzianum, are known to enhance the AMF symbiosis with vascular plants. However, information about their role in AMF symbiosis is still limited. Shoots of (Avocet S) wheat seedlings were sprayed with the fungal culture filtrate and gene expression patterns were analyzed in the treated tissues. An increase in the level of mRNA of arbuscular mycorrhizal protein comparing with control was found. The over-expression of this protein in wheat tissues might contribute in initiation of AMF colonization in wheat tissues. The result of this study can spark future researches to elucidate possible role of this protein in the symbiotic interaction mechanisms between soil AMF and various plant roots.
