We generated 126.53Gb raw reads from Illumina and 63.61Gb raw reads from Nanopore sequencing platforms, and retained 17.10Gb and 3.78Gb, respectively, after filtering, error-correction and decontamination (see Methods, Supplementary Figs. In A. angustus, the cupin gene family has undergone a significant expansion (Supplementary Table 25) such that it comprises more bicupin genes than any other plant (Fig. Heterogamy (production of two types of gametes) is evolved, forming non motile egg containing stored food and motile sperms. Camacho, C. et al. Resemblance of Bryophytes with Pteridophytes: 2. & Buck, W. R. in The Evolution of Plant Form (eds Ambrose, B. Later, algae, fungi and lichens were placed in a separate division Thallophyta and liverworts, mosses in division Bryophyta. 5. Name the types of nitrogenous bases present in the RNA. The world of mosses, liverworts and hornworts, collectively known as bryophytes, form a beautiful miniature forest; nonetheless they are often overlooked, due to their small size and lack of colorful flowers. Bryophytes, including mosses, liverworts and hornworts are early land plants that have evolved key adaptation mechanisms to cope with abiotic stresses and microorganisms. 2. We dedicate the paper to Yang Zhong in memory of his support and valuable suggestions on this project. 28, 2730 (2000). They are cosmopolitan in distribution and are found growing both in the temperate and tropical regions of the world at an altitude of 4000-8000 feet. 1. land plants: bryophytes mark the transition to land and the origin of vascular plants, and hence, link the seed and vascular plants to their algal ancestors. Genes were defined as tandemly arrayed genes if they belonged to the same family, were located within 100kb each other, and were separated by zero, one or fewer, five or fewer, or ten or fewer non-homologous intervening spacer genes104.

The A. angustus genome comprises 333 putative transcription factor (TF) genes covering 61 families, a number that is highly similar to that of the other two bryophyte genomes (Supplementary Fig. Katoh, K., Kuma, K. I., Toh, H. & Miyata, T. MAFFT version 5: improvement in accuracy of multiple sequence alignment. 59 and Supplementary Note 5.3). The divergence time was estimated using the MCMCTree program in the PAML package (v.4.7)93 under the nucleotide general time reversible (GTR) substitution model and with the independent rate model as the molecular clock model. At least 9.82% of protein-coding genes in A. angustus form tandem clusters in the genome (Supplementary Table 30 and Supplementary Note 5.4), compared with only 1% in P. patens14 and 5.9% in M. polymorpha15. According to the NCBI taxonomy categories of best BLAST hits, the source of A. angustus genes were classified (Supplementary Fig. Environ. conceived the paper; Z.-D.C., Z.-J.L. Bryopsida. 3a, Supplementary Figs. Nucleic Acids Res. A similar trend characterizes the genome of Marchantia and of the ancestor common to all bryophytes, whereas P. patens has gained more families (that is, 1,334) than it has lost (that is, 1,248; Fig. 7. acknowledges support from the European Union Seventh Framework Programme (FP7/2007-2013) under European Research Council Advanced Grant Agreement 322739DOUBLEUP. Biol. Majority of the species are terrestrial but a few species grow in fresh water (aquatic) e.g., Riccia fluitans, Ricciocarpos natans, Riella etc. The numbers of gained (blue) and lost (red) gene families are shown above the branches. 81, 7380 (2017).

Bryophytes grow densely in moist and shady places and form thick carpets or mats on damp soils, rocks, bark of trees especially during rainy season. Origin of Bryophytes 3. Villarreal, J. C. & Renzaglia, K. S. The hornworts: important advancements in early land plant evolution. The genome of hornwort A. angustus shows no evidence of WGDs and low genetic redundancy for networks underlying plant body plan, which may be congruent with an overall simple body plan. For the bryophyte-specific HGT, we extracted gene families that are common to at least two of the three members of bryophytes (moss P. patens, liverwort M. polymorpha and hornwort A. angustus). Rhizoids and Scales 11. Society member access to a journal is achieved in one of the following ways: Many societies offer single sign-on between the society website and Oxford Academic. Natl Acad. Production of large number of thick walled spores. Bot. All data that support the findings of this study are also available from the corresponding authors upon request.

The sporophytes of A. angustus were detached from the gametophytes, sterilized in 10% sodium hypochlorite and subsequently rinsed with distilled water56. The Actinobacteria-derived DNA methyltransferase genes that are present only in the three groups of bryophytes are related to DNA repair54 (Fig. Further comparative genomic analyses revealed that multiple whole-genome duplications might have contributed to the species richness and morphological diversity in mosses. 3941). Five families were acquired from fungi, belonging to Ascomycota, Basidiomycota, hornwort-symbiotic Chytridiomycota or Mucoromycota13 (Fig. of Washington, 2005). Cell 174, 448464 (2018). USA 109, 1887318878 (2012). 4). Since spores are aposymbiotic, we did not find the phenomenon of mucilage-filled cavities colonization by cyanobacteria on the A. angustus gametophyte during the sterile culture. 17. This class is represented by about 6 genera and 300 species. Biochem. Only high-quality reads with a total length of 126,532,381,412bp were used for further analysis (Supplementary Table 1). To preliminarily determine whether these clusters are HGT candidates, we submitted the corresponding A. angustus members of each cluster to the NCBI protein database for BLASTP search and checked the taxonomy report of the top 1,000 BLAST hits (Supplementary Note 7.2). Among the TEs, long terminal repeats (LTRs) are the most abundant (Supplementary Table 7). The class II RSL, class B ARF, NCARF and short PIN genes all have auxin-related functions (Supplementary Note 4.2). 14.

In animal kingdom class Amphibia (Gr. Holt, C. & Yandell, M. MAKER2: an annotation pipeline and genome-database management tool for second-generation genome projects. It implies that the CCM could be an ancestral mechanism of CO2 fixation by plants, and pyrenoids for CCM are homologous between hornworts and green algae, whereas both CCM components and pyrenoids have undergone multiple losses in land plants in response to atmospheric changes in terrestrial environments10,48. Bryophytes (commonly referred to as mosses) are the first dwellers of the land plant history, play a spirited role in ecosystems. Amphi = two or both; bios = life) includes those vertebrates which are amphibians in nature i.e., they can live on land as well as in water. Bryophytes are the closest extant relatives of early terrestrial plants. in this video lecture i explained all the adaptations that was developed by the bryophytes to adapt land habitat Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. a, A summary of the number of cupin genes from nine species based on a Pfam search of cupin_1 domain (PF00190). 6 and Supplementary Note 7.1).

We chose the longest transcript to represent each gene and removed mitochondrial and chloroplast genes. Front. PubMed Central For instance, most hornworts have chloroplasts with CO2-concentrating pyrenoids, which have not been found in any other land plants but are widespread among green algae10. 7). Mosses are one of the most ancient groups of land plants, with an estimated age of divergence from liverworts of 470-475 million years B.P. Tandem Repeats Finder (v.4.09)67 was used to search for tandem repeats in the A. angustus genome. The lack of class II RSL genes in A. angustus might be related to the morphological simplification of this species with respect to tip-growing filamentous structures2. 11. Moss capsule is similar to terminal sporangium and columella of Psilophytales. identified HGT; A.Z. In thalloid forms rhizoids are borne on the ventral surface (Fig. 67 and 72 and Supplementary Note 6.2). In Bryophytes roots are absent and the functions of the root i.e., anchorage and absorption is performed by the filamentous structures known as rhizoids.
