1bd), providing strong evidence for the lack of WGD in Anthoceros. Phylogenet. Otocinclus: Oto Catfish Care Guide & Species Profile With about 850 accepted species of liverworts and hornworts (720 in Colombia, 720 in Ecuador) and an endemism rate of about 10 percent, Colombia and Ecuador count among the most speciose regions on Earth. Nucleic Acids Res. The hornworts, formally known as Anthocerotae, are a monophyletic group comprising a third extant lineage of nonvascular land plants. Lejeunea is the largest genus with 66 species, followed by Plagiochila (65 spp.). While they grow most abundantly in more humid climates and can't tolerate extremely arid environments, they can be found in moist pockets of the desert or near the intertidal zone on the coastlines. Consequently, if their environment doesnt have moisture available, they will go into a water-stressed state called desiccation. Natl Acad. 90, 560572 (2017). 21, 18131819 (2004). Because the diffusion rate of carbon dioxide is 10,000-fold higher in air than in water, aquatic algae require a mechanism to concentrate CO2 in chloroplasts so as to allow the photosynthetic RuBisCo protein to function efficiently. In addition to having characteristics exclusively shared with algae or with other land plants, hornworts also have a wide range of distinctive biological features. Nevertheless, firm evidence supporting the homology of meristems as well as stomata is scarce. 58, 766777 (2009). The horn itself is an amazing structure. Rousk, K., Jones, D. L. & DeLuca, T. H. Mosscyanobacteria associations as biogenic sources of nitrogen in boreal forest ecosystems. Sakakibara, K. et al. Rensing, S. A. et al. Diversity and Endemism | SpringerLink Native to Florida Species Overview This plant is also known as hornwort. Mol. After removal of the coverslip, the slides were air-dried for 10min at room temperature and then extracted with methanol at 20C for 10min. 33, 290295 (2015). F.-W.L., P.S., K.S., T.N., J.C.V., E.F. and M.W. Whole-genome duplications (WGD) have played an important role in shaping plant evolution and possibly underlie several adaptive radiations22. Symbiotic cyanobacteria have not been reported in Megaceros or Folioceros. Lab 21 Flashcards | Quizlet F1000Res. Hornworts don't have the slime papillae that are found in many liverworts, but appear to be able to produce mucilage in almost any cell. Maere, S., Heymans, K. & Kuiper, M. BiNGO: a Cytoscape plugin to assess overrepresentation of gene ontology categories in biological networks. 44, 122128 (2018). Guindon, S. et al. In bryophytes, although mosses frequently harbour epiphytic cyanobacteria47, only hornworts and two liverwort species host cyanobacteria endophytically within specialized slime-filled cavities15,46. CAS However, unlike C. reinhardtii, we did not find LCIB to be differentially expressed when plants are grown at different CO2 levels (Supplementary Fig. A Medicago truncatula SWEET transporter implicated in arbuscule maintenance during arbuscular mycorrhizal symbiosis. Unraveling ancient hexaploidy through multiply-aligned angiosperm gene maps. Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae. Cultures of A. agrestis (Oxford and Bonn strains) and A. punctatus were all derived from a single spore and axenically propagated and maintained on either BCD67 or Hatchers68 media. While Orthofinder2 (ref. It's also a plant that can either float or root itself. MacLean, A. M., Bravo, A. Hornwort is a cosmopolitan submerged plant found in freshwaters in most parts of the world. Frontiers | What can hornworts teach us? The presence of stomata on sporophytes and the ability of some hornwort sporophytes to branch (and sometimes even live independently from the gametophyte!) carried out chromosome work. Lee, L. R. & Bergmann, D. C. The plant stomatal lineage at a glance. 3) and read mapping statistics (Supplementary Tables 2 and 3), show that the three genomes are of high quality and accuracy. Article InterPro in 2019: improving coverage, classification and access to protein sequence annotations. However, their methods of absorbing minerals and water are starkly different from their vascular cousins. 137) to remove positions with more than 20% of gaps. The mean insert size and #READ_PAIRS were calculated using picard CollectInsertSizeMetrics. Proc. Bioscience 48, 266276 (1998). a, Circos plot of A. agrestis Bonn showing the densities of repeats, genes and single nucleotide polymorphisms (SNPs) with the A. agrestis Oxford genomes. Mapleson, D., Venturini, L., Kaithakottil, G. & Swarbreck, D. Efficient and accurate detection of splice junctions from RNA-seq with Portcullis. Nuclear protein phylogenies support the monophyly of the three bryophyte groups (Bryophyta Schimp). Similar to M. polymorpha and P. patens, salicylic acid signalling components, but not the receptor-related genes, are found in hornworts. Homologues to symbiotic genes were retrieved in 31 species covering the different plant lineages (Supplementary Table 11) using protein from the model plant Medicago truncatula and the tBLASTn v.2.9.0+ (ref. and D.Q. Hornworts, Phylum Anthocerotophyta. We then plotted repeat unit size against tandem array size to look for bimodal distribution. Classification of the Phylum Anthocerotophyta Stotl. 111) to summarize all the 742 gene trees and measured branch supports as local posterior probabilities112. Natl Acad. The tendency of an organisms water content to change with its environment is called poikilohydric. The hornworts are the smallest and least diverse clade within bryophytes, consisting of c. 220 species (Sderstrm et al ., 2016) that are geographically widespread primarily in tropical areas (Villarreal et al ., 2014 ). We have not succeeded in reconstituting hornwortAMF symbiosis in vitro and hence are unable to test expression of these orthologues in the context of AMF. 3d), suggesting that they may have similar roles in stomatal patterning in hornworts.

For each analysis, we used protein-guided DNA alignments to align our nucleic acid sequences while maintaining reading frame. Both kinds of organs develop just below the surface of the plant and are only later exposed by disintegration of the overlying cells. Current Biology 29, 27432750 (2019). Second, the hornwort sporophyte maintains a basal sporophytic meristem producing cells that continuously differentiate into mature tissues towards the tip. Recent genetic studies have identified a suite of genes in the angiosperms that regulate the establishment and maintenance of AMF symbiosis42. Proc. 7). Traditionally, there was a single class of hornworts, called Anthocerotopsida, or older Anthocerotae. For A. agrestis we also created a pan genome combining genome assemblies and gene annotations of the two strains (Bonn and Oxford) in a non-redundant way (see Methods, Supplementary Table 5 and Supplementary notes). 1). Cove, D. J. et al. Arrowhead points to a cyanobacteria colony. For the EPF and EPF-like gene family, we used the matrix compiled by Takata et al.136 and added the Anthoceros and M. polymorpha homologues. Atkinson, N. et al. We used both individual approaches (prediction of genes for each genome separately, see (1)(5) below) and comparative (simultaneous prediction of gene models for the genomes, see (5) below) approaches to increase the accuracy and compatibility of gene annotations. Genome Res. Trees were visualized with the iTOL platform v.4.4.2 (ref. [23] Chromosome-scale genome sequencing of three hornwort species corroborate that stomata evolved only once during land plant evolution. 174, 788797 (2017). PubMed Many hornworts develop internal mucilage-filled cavities or canals when groups of cells break down. The search parameters were otherwise set as the default. We used all RNA-seq evidence available owing to the low nucleotide divergence among the three genomes. To study the collinearity across all plants, we first created orthogroups with proteomes of 19 species using Orthofinder2 (ref. The following gene prediction approaches were used. Here we generated RNA-seq data to compare the gene expression of symbiont-free (either nitrogen-starved or nitrogen-fed) and symbiosis-reconstituted hornworts (Fig. Orthologues of SMF, TMM and EPF were absent in M. polymorpha, consistent with the fact that liverworts do not have stomata8. Felsenstein, J. PHYLIP (Phylogeny Inference Package) Version 3.697 (University of Washington, 2015); http://evolution.genetics.washington.edu/phylip/oldversions.html. Walker, B. J. et al. Held in gemma cups, these disks of tissue are produced from the gametophyte. Pyrenoids can thus boost photosynthetic efficiency and reduce photorespiration. (4) We used the RNA-seq evidence to automatically train genemark and obtain gene predictions. Hornwort | plant, division Anthocerotophyta | Britannica Gene-tree/species-tree discordance in terms of quartet frequencies was calculated by DiscoVista113. The ML tree was inferred by RAxML with -f a -# 100 -m PROTGAMMAJTTDCMUTF and supplying -p and -x from random number generator. Despite its streamlined nature, some TAPs were only found in hornworts and vascular plants but not in the other two bryophyte genomes, with the most notable example being YABBY (Supplementary Table 8 and Supplementary Note).

PubMed Central You are using a browser version with limited support for CSS. 6, e4958 (2018). Biol. Hornwort spores are relatively large for bryophytes, measuring between 30 and 80 m in diameter or more. Impact of whole-genome duplication events on diversification rates in angiosperms. ; funding from Foundation of German Business (sdw), Georges and Antoine Claraz Foundation and URPP Evolution in Action to A.N. Steinberg, N. A. liverworts, and hornworts are non-vascular terrestrial plants that together are referred to as the bryophytes. PubMed Central Hornworts may be found worldwide growing primarily in places that are damp or humid. Algal and hornwort chloroplasts use inorganic carbon transporters and carbonic anhydrases to locally concentrate CO2 in the pyrenoids, a specialized chloroplast compartment where RuBisCOs aggregates. To infer gene trees, we used both the amino acid and nucleotide matrices, and employed the maximum likelihood method implemented in IQ-Tree v.1.6.12 (ref. 35, 15471549 (2018). Front. Edgar, R. C. MUSCLE: multiple sequence alignment with high accuracy and high throughput. However, the most recent phylogenetic evidence leans strongly towards bryophyte monophyly,[26][27][28][29][30][31][24][32][33][excessive citations] and it has been proposed that hornworts are de-ranked to the original class Anthocerotopsida.[28]. We used Orthofinder2 (ref. Ch 18 Flashcards | Quizlet 15, 550 (2014). Evol. Bioinformatics 21, 34483449 (2005). Bioinformatics 34, i884i890 (2018). Anthocerotophyta - an overview | ScienceDirect Topics Hornworts uniquely possess a combination of traits that connect them with both green algae and other land plant lineages9. (3) We trained Augustus using both protein and RNA-seq evidence within Braker2 (EPT mode of Braker2). This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter, and several layers of cells in thickness. Altogether, these findings imply that the deep divergence of the moss, hornwort and liverwort genomes may have led to limited collinearity among bryophytes, as well as between bryophytes and vascular plants. We subjected the plant cultures to one of the three CO2 environments at 150ppm (low), 400ppm (ambient) and 800ppm (high) in a CO2-controlled growth chamber for 10d (12h/12h day/night cycle). Evolutionary relationship and structural characterization of the EPF/EPFL gene family. PC1 and PC2 refer to the first and second axes of principal component analysis on gene expression values. ; Japan Society for the Promotion of Science (JSPS) grant no. The three hornwort genomes show a high gene density compared to other land plants (Supplementary Table 6). 40, e11 (2012). We run Tandem Repeats Finder120 to identify tandem repeats with a minimum alignment score of 50 and a maximum period size of 2,000bp. The slides were then pressed with a thumb directly over the coverslip. Zhang, C., Rabiee, M., Sayyari, E. & Mirarab, S. ASTRAL-III: polynomial time species tree reconstruction from partially resolved gene trees. Meeks, J. C. Symbiosis between nitrogen-fixing cyanobacteria and plants. Article Hornwort is most often used as an aquatic plant in aquariums because it grows quickly, but it also makes for great pond plants. Google Scholar. Trends Plant Sci. Additional hornwort LCIB homologues were retrieved from the 1,000 plant transcriptome database6. When the sporophyte is mature, it has a multicellular outer layer, a central rod-like columella running up the center, and a layer of tissue in between that produces spores and pseudo-elaters. Mol. Stomatal development in A. thaliana and P. patens is regulated by a conserved genetic toolbox, including the basic helixloophelix (bHLH) transcription factors SMF (SPCH, MUTE and FAMA), ICE/SCREAMs (SCRMs), EPIDERMAL PATTERNING FACTOR (EPF), ERECTA and TOO MANY MOUTHS (TMM) genes34,35. Lang, D. et al. Finally, we found that the genes required for AMF symbiosis are conserved in Anthoceros (Fig. Read quality and adaptor trimming was done by fastp71 with the default setting. Nat. Thalloid liverworts grow horizontally and have wide, flat leaves that are rubbery. The search parameters were otherwise as default. Distribution and Diversity . 9). Similar to the green algae, hornwort chloroplasts contain a pyrenoid where starch storage is concentrated. 26, 342350 (2016). annotated the genomes. New Phytol. 219, 10181030 (2018). The Physcomitrella patens chromosome-scale assembly reveals moss genome structure and evolution. USA 103, 1551115516 (2006). Hornworts are somewhat rare and quite small, and they prefer shady and wet places. The best-fitting model was chosen as LG+G+I using the FindBestProteinModel function. Lignin is a polymer that gives plants structure, allowing plants to grow tall. TAPs were annotated using TAPscan, according to Wilhelmsson et al.24 and compared with selected other organisms using the major protein of each gene model (.1 splice variant). RNA was extracted by the Spectrum Total RNA Plant Kit (Sigma-Aldrich). Plant Microbe Interact. Hornworts There are about 100 species of hornworts in the world. T.B. To obtain protein homology information, we retrieved the 19 proteomes (only primary transcripts; Supplementary Table 15) and aligned them to the genome assemblies using exonerate98. All the hornwort LCIB sequences have the conserved amino acid residues at the active sites that are shared with other algal LCIBs61 (Fig. While liverworts can follow the typical life cycle of bryophytes, most can reproduce asexually using a gemmae. Plant J. Class 1 Knotted1-like homeobox (KNOX1) genes regulate sporophytic meristem activity in both P. patens and vascular plants27, while Class 2 Knotted1-like homeobox (KNOX2) genes maintain sporophyte cell fate in P. patens28. Sayou, C. et al. Home > Plant encyclopedia > Bryophytes (Mosses, Liverworts, and Hornworts). EPF4 and EPF6 in A. thaliana are involved in coordination of the central and peripheral zone in SAM36. 2 (eds Goffinet, B. Hornworts (Bryophytes) - LC Linked Data Service: Authorities and Hornworts may be found worldwide, though they tend to grow only in places that are damp or humid. performed synteny analyses. Hornwort Facts, Care & Planting Guide (Ceratophyllum demersum) Maximum target was set to 250 and the word size as 2. Instead, it grows in thick clumps to form domes of green. For YABBY, the 107 OTU dataset from Finet et al.135 was downloaded from treebase and combined with YABBY genes from Huperzia and Anthoceros. 6, 1287 (2017). Leafy liverworts more commonly sport the globe spore capsule while thalloid liverworts the flower-like capsule. Because the resulting gene models were heavily dependent on the training data, we decided to generate multiple gene predictions and build consensus gene models using EVidenceModeler (EVM)101. 105) with default parameters and alignments were cleaned using TrimAl v.1.4 (ref. Bighorn Hornwort (Megaceros aenigmaticus) forms very thin dark green sheets on wet rocks. The sporophyte in hornworts is unique among bryophytes in being long-lived with a persistent photosynthetic capacity. 2009, db.prot5136 (2009). 36, 908918 (2019). This is a completely submersed plant and is commonly seen in ponds, lakes, ditches, and quiet streams with moderate to high nutrient levels. [3][4] The pyrenoid, which is both a food storing organ and enables a more efficient photosynthesis, have evolved independently five to six times in hornworts and is present in half of the roughly 200 species. Article In addition to EPF, an EPF-like gene in the EPFL4-6 clade, was found in hornworts (Supplementary Fig. The largest genus of hornworts, Anthoceros, can be found worldwide, but many of the other genera can only be found in tropical ecosystems. We then used single-linkage clustering to construct gene families and estimate KS divergence using phylogenetic analysis by maximum likelihood (PAML)123 with the F3X4 model for each node in the gene family phylogenies. The best-fitting substitution models were selected by ModelFinder108. As will be the case with all plants, archegonia produce one or more eggs and antheridia produce many sperm. On the exterior of the thallus, simple pores allow for gas exchange. 3a and Supplementary Table 8). These incredible plants can be found all over the world including Antarctica and the Arctic! Anthocerotophyta (Hornworts) The Biology Primer They are often found growing on the muddy sides of waterways, from small ditches to larger creeks.
