Abstract Premise Bryophytes form a major component of terrestrial plant biomass, structuring ecological communities in all biomes. Our understanding the evolutionary history hornworts, liverworts, and mosses has been significantly reshaped by inferences from molecular data, which have highlighted extensive homoplasy various traits repeated bursts diversification. However, timing key events phylogeny, patterns, processes diversification across bryophytes remain unclear. Methods Using GoFlag probe set, we sequenced 405 exons representing 228 nuclear genes for 531 species 52 54 orders bryophytes. We inferred phylogeny gene tree analyses using concatenated coalescence approaches, assessed conflict, estimated divergences based on 29 fossil calibrations. Results The resolves many relationships bryophytes, enabling us to resurrect five liverwort recognize three more propose 10 new mosses. Most originated Jurassic diversified Cretaceous or later. phylogenomic data also highlight topological conflict parts tree, suggesting complex that cannot be adequately captured single gene‐tree topology. Conclusions sampled hundreds loci broad phylogenetic spectrum spanning at least 450 Ma evolution; these resolved critical nodes need explore mechanisms underlying ambiguity specific nodes. provide an expandable framework toward reconstructing comprehensive this important group plants.

Phylogeny and evolution of streptophyte algae

Annals of Botany, Journal Year: 2024, Volume and Issue: 134(3), P. 385 - 400

Published: June 4, 2024

Abstract The Streptophyta emerged about a billion years ago. Nowadays, this branch of the green lineage is most famous for one its clades, land plants (Embryophyta). Although Embryophyta make up major share species numbers in Streptophyta, there diversity probably >5000 streptophyte algae that form paraphyletic grade next to plants. Here, we focus on deep divergences gave rise streptophytes, hence particularly algae. Phylogenomic efforts have not only clarified position relative plants, but recent also begun unravel relationships and radiations within algal diversity. We illustrate how new phylogenomic perspectives changed our view evolutionary emergence key traits, such as intricate signalling networks are intertwined with multicellular growth chemodiverse hotbed from which they emerged. These traits biology were bequeathed their progenitors.

Structure, biogenesis, and evolution of thylakoid membranes

The Plant Cell, Journal Year: 2024, Volume and Issue: 36(10), P. 4014 - 4035

Published: April 3, 2024

Cyanobacteria and chloroplasts of algae plants harbor specialized thylakoid membranes (TMs) that convert sunlight into chemical energy. These house PSII I, the vital protein-pigment complexes drive oxygenic photosynthesis. In course their evolution, TMs have diversified in structure. However, core machinery for photosynthetic electron transport remained largely unchanged, with adaptations occurring primarily light-harvesting antenna systems. Whereas cyanobacteria are relatively simple, they become more complex plants. The vascular contain intricate networks stacked grana unstacked stroma thylakoids. This review provides an in-depth view TM architectures phototrophs determinants shape forms, as well presenting recent insights spatial organization biogenesis maintenance. Its overall goal is to define underlying principles guided evolution these bioenergetic membranes.

Vertebrates encode three whose possible functional specialization is debated. In land plants, has expanded from one member basal lineages to eleven so-called EVOLUTIONARILY CONSERVED C-TERMINAL REGION1-11 (ECT1-11) Arabidopsis thaliana, named after conserved YTH placed behind a long N-terminal intrinsically disordered region (IDR).

Immense chemical diversity is one of the hallmark features plants. This chemo-diversity mainly underpinned by a highly complex and biodiverse biochemical machinery. Plant metabolic enzymes originated were inherited from their eukaryotic prokaryotic ancestors further diversified unprecedentedly high rates gene duplication functionalization experienced in land Unlike microbes, which display frequent horizontal transfer events multiple inputs energy organic carbon, plants predominantly rely on carbon generated CO 2 have relatively few transfers during recent evolutionary history. As such, plant networks evolved stepwise manner using existing as starting point under various constraints.

Abstract The Klebsormidiophyceae are a class of green microalgae observed globally in both freshwater and terrestrial habitats. Morphology‐based classification schemes this have been shown to be inadequate due the simple morphology these algae, tendency vary culture versus field conditions, rampant morphological homoplasy. Molecular studies revealing cryptic diversity renewed interest group. We sequenced complete chloroplast genomes broad series taxa spanning known taxonomic breadth class. also three strains Streptofilum , recently discovered algal lineage with close affinity Klebsormidiophyceae. Our results affirm previously hypothesized polyphyly genus Klebsormidium as well nominal species genus, K. flaccidum . Furthermore, plastome sequences strongly support status distinct, early‐diverging charophytic algae sister clade comprising plus Phragmoplastophyta. uncovered major structural alterations that implications regarding underlying mechanisms genome evolution.
