Molecular Phylogeny of Chinese Thuidiaceae with Emphasis on Thuidium and Pelekium
Molecular Phylogeny of Chinese Thuidiaceae with emphasis on Thuidium and Pelekium QI-YING, CAI1, 2, BI-CAI, GUAN2, GANG, GE2, YAN-MING, FANG 1 1 College of Biology and the Environment, Nanjing Forestry University, Nanjing 210037, China. 2 College of Life Science, Nanchang University, 330031 Nanchang, China. E-mail: [email protected] Abstract We present molecular phylogenetic investigation of Thuidiaceae, especially on Thudium and Pelekium. Three chloroplast sequences (trnL-F, rps4, and atpB-rbcL) and one nuclear sequence (ITS) were analyzed. Data partitions were analyzed separately and in combination by employing MP (maximum parsimony) and Bayesian methods. The influence of data conflict in combined analyses was further explored by two methods: the incongruence length difference (ILD) test and the partition addition bootstrap alteration approach (PABA). Based on the results, ITS 1& 2 had crucial effect in phylogenetic reconstruction in this study, and more chloroplast sequences should be combinated into the analyses since their stability for reconstructing within genus of pleurocarpous mosses. We supported that Helodiaceae including Actinothuidium, Bryochenea, and Helodium still attributed to Thuidiaceae, and the monophyletic Thuidiaceae s. lat. should also include several genera (or species) from Leskeaceae such as Haplocladium and Leskea. In the Thuidiaceae, Thuidium and Pelekium were resolved as two monophyletic groups separately. The results from molecular phylogeny were supported by the crucial morphological characters in Thuidiaceae s. lat., Thuidium and Pelekium. Key words: Thuidiaceae, Thuidium, Pelekium, molecular phylogeny, cpDNA, ITS, PABA approach Introduction Pleurocarpous mosses consist of around 5000 species that are defined by the presence of lateral perichaetia along the gametophyte stems. Monophyletic pleurocarpous mosses were resolved as three orders: Ptychomniales, Hypnales, and Hookeriales (Shaw et al. -
Mitochondrial Genomes of the Early Land Plant Lineage
Dong et al. BMC Genomics (2019) 20:953 https://doi.org/10.1186/s12864-019-6365-y RESEARCH ARTICLE Open Access Mitochondrial genomes of the early land plant lineage liverworts (Marchantiophyta): conserved genome structure, and ongoing low frequency recombination Shanshan Dong1,2, Chaoxian Zhao1,3, Shouzhou Zhang1, Li Zhang1, Hong Wu2, Huan Liu4, Ruiliang Zhu3, Yu Jia5, Bernard Goffinet6 and Yang Liu1,4* Abstract Background: In contrast to the highly labile mitochondrial (mt) genomes of vascular plants, the architecture and composition of mt genomes within the main lineages of bryophytes appear stable and invariant. The available mt genomes of 18 liverwort accessions representing nine genera and five orders are syntenous except for Gymnomitrion concinnatum whose genome is characterized by two rearrangements. Here, we expanded the number of assembled liverwort mt genomes to 47, broadening the sampling to 31 genera and 10 orders spanning much of the phylogenetic breadth of liverworts to further test whether the evolution of the liverwort mitogenome is overall static. Results: Liverwort mt genomes range in size from 147 Kb in Jungermanniales (clade B) to 185 Kb in Marchantiopsida, mainly due to the size variation of intergenic spacers and number of introns. All newly assembled liverwort mt genomes hold a conserved set of genes, but vary considerably in their intron content. The loss of introns in liverwort mt genomes might be explained by localized retroprocessing events. Liverwort mt genomes are strictly syntenous in genome structure with no structural variant detected in our newly assembled mt genomes. However, by screening the paired-end reads, we do find rare cases of recombination, which means multiple concurrent genome structures may exist in the vegetative tissues of liverworts. -
Biodiversity of the Antarctic Flora

Peat, Andrew Clarke & Peter Convey 5 6 British Antarctic Survey, Natural Environment Research Council, High Cross, Madingley Rd, 7 Cambridge, CB3 0ET, UK. 8 E-mail: [email protected] 9 __________________________________________________________________________ 10 11 ABSTRACT 12 13 Aim To establish how well the terrestrial flora of the Antarctic has been sampled, how well 14 the flora is known, and to determine the major patterns in diversity and biogeography. 15 16 Location Antarctica south of 60°S, together with the South Sandwich Islands, but excluding 17 South Georgia, Bouvetøya and the periantarctic islands. 18 19 Methods Plant occurrence data were collated from herbarium specimens and literature 20 records, and assembled into the Antarctic Plant Database. Distributional patterns were 21 analysed using a geographic information system. Biogeographic patterns were determined 22 with a variety of multivariate statistics. 23 24 Results Plants have been recorded from throughout the Antarctic including all latitudes 25 between 60°S and 86°S. Species richness declines with latitude along the Antarctic 26 Peninsula, but there was no evidence for a similar cline in Victoria Land and the 27 Transantarctic mountains. MDS ordinations showed that the species composition of the 28 South Orkney, South Shetland Islands and the north western Antarctic Peninsula are very 29 similar to each other, as are the floras of different regions in continental Antarctica. However 30 they also suggest that the eastern Antarctic Peninsula flora is more similar to the flora of the 31 southern Antarctic Peninsula than to the continental flora (with which it has traditionally been 32 linked). -

Sixteen moss species are reported as new records from Gebel Dalfa and Ain Qadies of the Isthmic Desert in Northern Sinai, among these seven species are new records to the Isthmic Desert while Trichostomum brachydontium, is a new record to the flora of Egypt. This brings the total number of fully identified mosses known from Isthmic Desert to 32 taxa. Notes on habitats, fruiting, sex organs and gemmae are given. Key words: Bryoflora, Egypt, Isthmic Desert, moss flora, northern Sinai. Introduction The survey of the bryoflora of the Isthmic Desert in Northern Sinai has, so far, been limited to four localities: 1- Arif El-Naga, 2- Gebel Halal, 3- Gebel Libni and 4- Gebel El- Godyrat (Table 1, Fig. 1). From these localities, Bilewsky (1974), Shabbara (1999) and Abou-Salama & El-Saadawi (2000) reported 33 mosses of which the following 25 species (Table 1) were fully identified.
