寄生植物作为植物界的重要组成部分，其异养策略引起了许多科学家的兴趣。为了更好地了解寄生植物与其寄主之间的相互作用，已经进行了大量的研究。然而，从菌根的角度对寄生植物的研究是缺乏的，主要是因为寄生植物不形成菌根协会的概念。尽管长期以来一直被认为是非菌根的，但最近发现一些马先蒿属物种被菌根真菌大量定植。由于中国马先蒿属植物寄生性的确切资料缺乏，我们对云南西北部29种马先蒿属植物的菌根状况和寄生性进行了调查，以验证部分马先蒿属植物可能同时具有菌根和寄生性的假说。大多数被研究的物种被发现是寄生以及菌根。在某些情况下，寄生器官和丛枝菌根真菌（AMF）检测在同一根。结果表明，一些马先蒿属物种可能有另一种营养策略（例如，真菌营养），除了寄生。此外，研究结果表明，在马先蒿属植物的栽培中，应考虑寄主植物以及AMF。
As an important component of plant kingdom, parasitic plants have intrigued many scientists with their heterotrophic strategy. Numerous investigations have been carried out for a better understanding of interactions between parasitic plants and their hosts. Nevertheless, studies on parasitic plants from a mycorrhizal perspective are lacking, largely because of the notion that parasitic plants do not form mycorrhizal associations. Although long being regarded as nonmycorrhizal, some Pedicularis species are recently found to be heavily colonized by mycorrhizal fungi. Because the precise information about parasitism of Chinese Pedicularis has been lacking, we surveyed both the mycorrhizal status and parasitism of 29 Pedicularis species from the northwest of Yunnan Province, China, to test the hypothesis that some Pedicularis may be mycorrhizal and parasitic simultaneously. The majority of studied species were found to be parasitic as well as mycorrhizal. In some cases, parasitic organs and arbuscular mycorrhizal fungi (AMF) were detected in the same rootlets. The results suggest that some Pedicularis species may have another nutrient strategy (e.g., mycotrophy) besides being parasitic. Also, the findings indicate that host plants as well as AMF should be taken into account in cultivation of Pedicularis species.
