摘要

Three species have been formerly segregated from Metzgeria in the genus Apometzgeria. One of the species, A. frontipilis, is endemic to South America but the second, A. pubescens, is currently understood as having a bipolar range with populations across the Holarctic and in southern South America. The third species, A. longlfrondis, was described from China (and is not included in this study). Species of bryophytes that range across continents and have little or no morphological variation among populations may nevertheless harbor morphologically cryptic genetic lineages. We used nuclear and plastid sequence data to examine the phylogenetic relationship between Apometzgeria and Metzgeria, and phylogeographic patterns in taxa assigned to Apometzgeria. Two species often assigned to Apometzgeria are phylogenetically embedded within Metzgeria in two separate clades, one comprising all Holarctic A. pubescens and a second with A. pubescens from South America and all accessions of A. frontipilis. Phylogenetic and haplotype analyses reveal a lack of phylogeographic structure among A. pubescens plants from throughout its Holarctic distribution. However, A. pubescens in South America is more closely related to A. frontipilis and species of Metzgeria from South America than to any A. pubescens from the Northern Hemisphere. Thus, A. pubescens is Holarctic in distribution and morphologically similar plants form a divergent lineage in South America. Our results do not support Apometzgeria as a separate genus in the Metzgeriaceae.

Pubescens目前被理解为拥有双极系列，南部南部南部的人口。来自中国的第三种，A. longlfrondis（并不包括在本研究中）。迄今为止，群体跨越大陆的苔藓植物种类可能在群体中几乎没有或没有形态变异，仍可能在不同的神秘隐秘的遗传谱系中。我们使用核和塑性序列数据来检查Apometzgeria和Metzgeria之间的系统发育关系，以及分配给Apometzgeria的征集中的植物局部图案。经常分配给Apometzgeria的两种物种在两个单独的植物中嵌入米尔血症中，其中包括所有热拉病A. Pubescens和来自南美洲的一秒钟，以及A. Frontipilis的所有登录。系统发育和单倍型分析揭示了A.缺乏缺乏的PubeScens植物中的缺乏。然而，南美洲的帕银斯与南美洲的北美洲的北极癖和物种比来自北半球的任何A.波巴斯群岛更密切。因此，A. Pubescens在分布和形态学上类似的植物形成了在南美洲的不同血统。我们的结果不支持Apometzgeria作为Metzgeriaceae的单独属。
