绝对时间从校准的DNA同源性可以用来推断谱系多样化，新的生态位的起源，或长距离扩散在塑造当前的分布格局的作用。然而，非维管植物的分子钟测年却落后于开花植物和动物测年。在这里，我们回顾约会的研究，专注于brabrites考虑到几个目标，（一），以促进交叉验证，通过比较率和时间到目前为止获得的;（二）总结率，产生了合理的结果，并可以在未来的研究中使用;（三）校准一个物种水平的基因组发生为Nothoceros，模型的质体基因组进化的金鱼藻。包括目前的工作，已经有18个分子钟研究苔类，苔藓，或金鱼藻，大多数与化石校准，一些地质校准或与以前公布的质体取代率。超过一半的研究通过使用替代校准方法交叉验证了推断的发散时间。质体取代率推断的“brathtes”是在被子植物研究中发现的一致，这意味着brathtes时钟模型可以校准与公布的替代率或化石，与两种方法测试和交叉验证对方。我们的系统发育ofNothocerosis的基础上44加入代表所有疑似物种和矩阵的6个标记的核，质体和线粒体DNA。结果表明，假角龙属共有10种，其中美洲9种，新西兰1种（N.新西兰种与智利姊妹种之间的分歧可以追溯到中新世，因此是由于长距离的扩散。在此基础上，我们将Megaceros的两个种正式转移到Nothoceros中，得到新的组合N. minarum（Nees）J.C. Villarreal和N.叶兰（Gottsche ex Steph.）J.C. Villarreal，我们还新synonymize八个名字描述在Megaceros。
Absolute times from calibrated DNA phylogenies can be used to infer lineage diversification, the origin of new ecological niches, or the role of long distance dispersal in shaping current distribution patterns. Molecular-clock dating of non-vascular plants, however, has lagged behind flowering plant and animal dating. Here, we review dating studies that have focused on bryophytes with several goals in mind, (i) to facilitate cross-validation by comparing rates and times obtained so far; (ii) to summarize rates that have yielded plausible results and that could be used in future studies; and (iii) to calibrate a species-level phylogeny forNothoceros, a model for plastid genome evolution in hornworts. Including the present work, there have been 18 molecular clock studies of liverworts, mosses, or hornworts, the majority with fossil calibrations, a few with geological calibrations or dated with previously published plastid substitution rates. Over half the studies cross-validated inferred divergence times by using alternative calibration approaches. Plastid substitution rates inferred for “bryophytes” are in line with those found in angiosperm studies, implying that bryophyte clock models can be calibrated either with published substitution rates or with fossils, with the two approaches testing and cross-validating each other. Our phylogeny ofNothocerosis based on 44 accessions representing all suspected species and a matrix of six markers of nuclear, plastid, and mitochondrial DNA. The results show thatNothoceroscomprises 10 species, nine in the Americas and one in New Zealand (N. giganteus), with the divergence between the New Zealand species and its Chilean sister species dated to the Miocene and therefore due to long-distance dispersal. Based on the new tree, we formally transfer two species ofMegacerosintoNothoceros, resulting in the new combinationsN. minarum(Nees) J.C. Villarreal andN. schizophyllus(Gottsche ex Steph.) J.C. Villarreal, and we also newly synonymize eight names described inMegaceros.
