Anthoceros genomes illuminate the origin of land plants and the unique biology of hornworts

Nature Plants, Journal Year: 2020, Volume and Issue: 6(3), P. 259 - 272

Published: March 13, 2020

Abstract Hornworts comprise a bryophyte lineage that diverged from other extant land plants >400 million years ago and bears unique biological features, including distinct sporophyte architecture, cyanobacterial symbiosis pyrenoid-based carbon-concentrating mechanism (CCM). Here, we provide three high-quality genomes of Anthoceros hornworts. Phylogenomic analyses place hornworts as sister clade to liverworts plus mosses with high support. The lack repeat-dense centromeres well whole-genome duplication, contain limited transcription factor repertoire. Several genes involved in angiosperm meristem stomatal function are conserved upregulated during development, suggesting possible homologies at the genetic level. We identified candidate found LCIB , Chlamydomonas CCM gene, is present but absent plant lineages, implying role function. anticipate these hornwort will serve essential references for future research comparative studies across plants.

The hornwort genome and early land plant evolution

Nature Plants, Journal Year: 2020, Volume and Issue: 6(2), P. 107 - 118

Published: Feb. 10, 2020

Abstract Hornworts, liverworts and mosses are three early diverging clades of land plants, together comprise the bryophytes. Here, we report draft genome sequence hornwort Anthoceros angustus . Phylogenomic inferences confirm monophyly bryophytes, with hornworts sister to mosses. The simple morphology correlates low genetic redundancy in plant body plan, while basic transcriptional regulation toolkit for development has already been established this lineage. Although is small characterized by minimal redundancy, expansions observed gene families related RNA editing, UV protection desiccation tolerance. A. bears signatures horizontally transferred genes from bacteria fungi, particular operating stress-response metabolic pathways. Our study provides insight into unique features their molecular adaptations live on land.

Evolution of Plant Hormone Response Pathways

Annual Review of Plant Biology, Journal Year: 2020, Volume and Issue: 71(1), P. 327 - 353

Published: Feb. 4, 2020

This review focuses on the evolution of plant hormone signaling pathways. Like chemical nature hormones themselves, pathways are diverse. Therefore, we focus a group whose primary perception mechanism involves an Skp1/Cullin/F-box-type ubiquitin ligase: auxin, jasmonic acid, gibberellic and strigolactone. We begin with comparison core these four hormones, which have been established through studies conducted in model organisms Angiosperms. With advent next-generation sequencing advanced tools for genetic manipulation, door to understanding origins mechanisms plants beyond few systems has opened. For example, in-depth phylogenetic analyses components now being complemented by early diverging land plants. Here discuss recent investigations how basal make sense hormones. Finally, propose connections between emergence complexity major developmental transitions evolution.

The Moss Physcomitrium (Physcomitrella) patens: A Model Organism for Non-Seed Plants

The Plant Cell, Journal Year: 2020, Volume and Issue: 32(5), P. 1361 - 1376

Published: March 9, 2020

Since the discovery two decades ago that transgenes are efficiently integrated into genome of Physcomitrella patens by homologous recombination, this moss has been a premier model system to study evolutionary developmental biology questions, stem cell reprogramming, and nonvascular plants. P. was first non-seed plant have its sequenced. With level genomic information, together with increasing molecular genetic tools, large number reverse studies propelled use system. A technological advances recently opened door forward genetics as well extremely efficient precise editing in patens. Additionally, careful phylogenetic increased resolution suggested emerged from within Physcomitrium. Thus, rather than patens, species should be named Physcomitrium Here we review these describe areas where had most impact on biology.

Chromatin Organization in Early Land Plants Reveals an Ancestral Association between H3K27me3, Transposons, and Constitutive Heterochromatin

Current Biology, Journal Year: 2020, Volume and Issue: 30(4), P. 573 - 588.e7

Genome packaging by nucleosomes is a hallmark of eukaryotes. Histones and the pathways that deposit, remove, read histone modifications are deeply conserved. Yet, we lack information regarding chromatin landscapes in extant representatives ancestors main groups eukaryotes, our knowledge evolution chromatin-related processes limited. We used bryophyte Marchantia polymorpha, which diverged from vascular plants circa 400 mya, to obtain whole chromosome genome assembly explore landscape three-dimensional organization an early diverging land plant lineage. Based on genomic profiles ten marks, conclude relationship between active marks gene expression conserved across plants. In contrast, observed distinctive features transposons other repetitive sequences compared with flowering Silenced repeats did not accumulate around centromeres. Although large fraction constitutive heterochromatin was marked H3K9 methylation as plants, significant proportion were H3K27me3, otherwise dedicated transcriptional repression protein-coding genes Chromatin compartmentalization analyses Hi-C data revealed repressed B compartments densely decorated H3K27me3 but or DNA reported that, played essential role function, suggesting ancestral this mark transposon silencing.

The C-Fern (Ceratopteris richardii) genome: insights into plant genome evolution with the first partial homosporous fern genome assembly

Scientific Reports, Journal Year: 2019, Volume and Issue: 9(1)

Published: Dec. 3, 2019

Abstract Ferns are notorious for possessing large genomes and numerous chromosomes. Despite decades of speculation, the processes underlying expansive ferns unclear, largely due to absence a sequenced homosporous fern genome. The lack this crucial resource has not only hindered investigations evolutionary responsible unusual genome characteristics ferns, but also impeded synthesis evolution across land plants. Here, we used model species Ceratopteris richardii address (e.g., polyploidy, spread repeat elements) by which high chromosome numbers typical may have evolved been maintained. We directly compared compositions in spanning green plant tree life diversity sizes, as well both short- long-read-based assemblies . found evidence consistent with single ancient polyploidy event history based on genomic cytogenetic data, proportions similar those flowering genomes. This study provides major stepping-stone understanding genomics providing first reference genome, insights into formation these massive

Published: March 18, 2020

Because of their high level diversity and complex evolutionary histories, most studies on plant receptor-like kinase subfamilies have focused domains. With the large amount genome sequence data available today, particularly basal land plants Charophyta, more attention should be paid to primary events that shaped RLK gene family. We thus focus motifs domains found in association with illustrate origin, organization, dynamics. discuss when these different domain associations first occurred how they evolved, based a literature review complemented by some our unpublished results.
