A highly repeated satellite DNA (Hy500) located in the centromeric heterochromatin of the European plethodontid salamander Speleomantes (formerly Hydromantes) was studied. The Hy500 family represents about 1% of the Speleomantes supramontis genome and has a major repeating unit of about 500 base pairs, which may have evolved from the progressive amplification of shorter sequences. This centromeric satellite is conserved in all the Speleomantes species, which nevertheless show distinct patterns of chromosomal distribution, which are of relevance as to their phylogenetic relationships.
对位于欧洲无肺螈科蝾螈Speleomantes（原Hydromantes）着丝粒异染色质中的一种高度重复卫星DNA（Hy500）进行了研究。Hy500家族约占Speleomantes supramontis基因组的1%，其主要重复单元约为500个碱基对，可能是由较短序列的逐步扩增进化而来。这种着丝粒卫星在所有Speleomantes物种中都保守存在，不过它们显示出不同的染色体分布模式，这与其系统发育关系相关。
