Tuber magnatum 出产世界上最昂贵的松露。这种真菌产生非常罕见的外生菌根，在现场很难甚至不可能检测到。最近开发了一种“实时”PCR 测定法来量化和追踪土壤中的 T. magnatum 菌丝体。在这里，该技术用于研究 T. magnatum 超自由基菌丝体在土壤生产力斑块中的空间分布及其跨季节的动态。这项研究是在位于意大利不同地区的四个不同的天然 T. magnatum 松露地进行的。在结果季节，T. magnatum 菌丝体的数量在结果点周围显着较高，并且随着远离结果点而减少。此外，生产斑块内的 T. magnatum 菌丝体经历了季节性波动。早春时，T. magnatum 菌丝体数量明显高于夏季。在夏季，可能由于炎热和干燥的季节，T. magnatum 菌丝显着减少，而在秋季又增加，并集中在假定的结果点。这些结果为 T. magnatum 生态学提供了新的见解，有助于规划最合适的采样策略来评估松露地的管理。
Tuber magnatum produces the world's most expensive truffle. This fungus produces very rare ectomycorrhizas which are difficult or even impossible to detect in the field. A “real-time” PCR assay was recently developed to quantify and to track T. magnatum mycelium in soil. Here, this technique was used to investigate the spatial distribution of T. magnatum extra-radical mycelium in soil productive patches and its dynamic across seasons. This study was carried out in four different natural T. magnatum truffle grounds located in different Italian regions. During the fruiting seasons, the amount of T. magnatum mycelium was significantly higher around the fruiting points and decreased going farther away from them. Moreover, T. magnatum mycelium inside the productive patches underwent seasonal fluctuations. In early spring, the amount of T. magnatum mycelium was significantly higher than in summer. In summer, probably due to the hot and dry season, T. magnatum mycelium significantly decreased, whereas in autumn it increased again and was concentrated at the putative fruiting points. These results give new insights on T. magnatum ecology and are useful to plan the most appropriate sampling strategy for evaluating the management of a truffle ground.
