In this study, we focused on plant-fungal relationships, partnership changes, and physiological mechanisms of carbon transfer in myco-heterotrophic plant-arbuscular mycorrhizal fungi interactions and conducted comprehensive analyses of the evolution of heterotrophy in plants. Molecular identifications showed that myco-heterotrophic plants and Gentiana zollingeri have mycorrhizal fungi of Glomus group A and the same fungi were found from some photosynthetic plant, especially plants belonging to Ophioglossaceae with high colonization rates. Partial sequences of hydrocarbon transporter genes from mycorrhizal fungi of myco-heterotrophic plants andG. zollingeri had no differentiations associated with trophic modes. However, there were possible differentiations in expression level of the genes between heterotrophic and autotrophic plants.

本研究围绕真菌异养植物-丛枝菌根真菌相互作用中的植物-真菌关系、配对变化和碳转移的生理机制进行了研究，并对植物异养的进化进行了全面的分析。分子鉴定结果表明，异养真菌和龙胆均含有A群菌根真菌，部分光合作用植物，特别是侵染率较高的蛇舌科植物中也发现了相同的真菌。异养真菌菌根真菌碳氢转运蛋白基因部分序列分析。Zollingeri没有与营养模式相关的分化。然而，异养植物和自养植物在基因表达水平上可能存在差异。
