真块菌（块菌属）是一类具有重要经济价值的子囊菌。在过去的30年中，对不同的松露物种进行了许多精细的群体遗传学研究，旨在回答有关其生命周期的几个关键问题;这些问题对于它们的栽培非常重要。现在很明显，松露是异宗配合的，但普遍的生活方式是单倍体。形成外生菌根和萌发子囊孢子的菌株分别作为母本和父本。与此同时，进行了一些大规模的研究，突出了末次冰期和河流隔离对松露遗传结构的影响。一个撤退到南部避难所在冰川期，并向北扩张后冰川期，被发现在所有研究的欧洲松露。地中海作为一个屏障，导致在不同的半岛上存在着单一物种的几个避难所。同样，中国西南部的大河也是该地区块菌基因流动的物理屏障。进一步的研究可特别注意分布范围广的物种的群体遗传学，如T。himalayense，以及块菌遗传结构与块菌相关细菌群落组成之间的相关性。
True truffle (Tuber spp.) is one group of ascomycetes with great economic importance. During the last 30 years, numerous fine-scale population genetics studies were conducted on different truffle species, aiming to answer several key questions regarding their life cycles; these questions are important for their cultivation. It is now evident that truffles are heterothallic, but with a prevalent haploid lifestyle. Strains forming ectomycorrhizas and germinating ascospores act as maternal and paternal partners respectively. At the same time, a number of large-scale studies were carried out, highlighting the influences of the last glaciation and river isolations on the genetic structure of truffles. A retreat to southern refugia during glaciation, and a northward expansion post glaciation, were revealed in all studied European truffles. The Mediterranean Sea, acting as a barrier, has led to the existence of several refugia in different peninsulas for a single species. Similarly, large rivers in southwestern China act as physical barriers to gene flow for truffles in this region. Further studies can pay special attention to population genetics of species with a wide distribution range, such as T. himalayense, and the correlation between truffle genetic structure and the community composition of truffle-associated bacteria.
