Sexual reproduction in Charophyceae abounds complex traits. Their gametangia develop as intricate structures, with oogonia spirally surrounded by envelope cells and richly pigmented antheridia. The red—probably protectant—pigmentation of antheridia is conserved across Charophyceae. Chara tomentosa is, however, unique exhibiting this pigmentation also vegetative tissue. Here, we investigated the two sympatric species, C. baltica , compared their molecular chassis for pigmentation. Using reversed phase C 30 high performance liquid chromatography (RP-C -HPLC), uncover that major pigments are β-carotene, δ-carotene γ-carotene; using headspace solid-phase microextraction coupled to gas equipped a mass spectrometer (HS-SPME-GC-MS), pinpoint unusually large carotenoid pool gives rise diverse volatile apocarotenoids, including abundant 6-methyl-5-hepten-2-one. Based on transcriptome analyses, signatures biology Charophycaee genes pigment production, monocyclized carotenoids. rich probably serves substrate carotenoid-derived metabolites, signified not only (i) apocarotenoids detected but (ii) expression gene coding cytochrome P450 enzyme related land plant proteins involved biosynthesis hormones. Overall, our data shed light key protection strategy sexual widespread group macroalgae. genetic underpinnings shared hundreds millions years algal evolution.

Abstract Zygnematophyceae are the algal sisters of land plants. Here we sequenced four genomes filamentous Zygnematophyceae, including chromosome-scale assemblies for three strains Zygnema circumcarinatum . We inferred traits in ancestor and plants that might have ushered conquest by plants: expanded genes signaling cascades, environmental response, multicellular growth. share all major enzymes cell wall synthesis remodifications, gene gains shaped this toolkit. Co-expression network analyses uncover cohorts unite with developmental programs. Our data shed light on a molecular chassis balances response growth modulation across more than 600 million years streptophyte evolution.

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.

The Auxin Response Factors (ARFs) family of transcription factors are the central mediators auxin-triggered transcriptional regulation. Functionally different classes extant ARFs operate as antagonistic auxin-dependent and -independent regulators. While part evolutionary trajectory to present auxin response functions has been reconstructed, it is unclear how emerged, early diversification led functionally proteins. Here, we use in silico vivo analyses revisit molecular events that origin subsequent evolution ARFs. We reveal shared from preexisting domains, uncovering a protein fold homologous ARF DNA-binding conserved eukaryotic chromatin regulator. Building on this, reconstruct complete history ARFs, including divergence leading appearance defining main targets for their functional diversification. derive emergence nuclear signalling pathway.

Abstract Land plants have diversified enzyme families. One of the most prominent is cytochrome P450 (CYP or CYP450) family. With over 443,000 CYP proteins sequenced across tree life, CYPs are ubiquitous in archaea, bacteria, and eukaryotes. Here, we focused on land algae to study role diversification. CYPs, acting as monooxygenases, catalyze hydroxylation reactions crucial for specialized plant metabolic pathways, including detoxification phytohormone production; CYPome consists one enormous superfamily that divided into clans Their evolutionary history speaks high substrate promiscuity; radiation functional diversification yielded numerous To understand relationships within employed sequence similarity network analyses. We recovered distinct clusters representing different families, reflecting their sequences link prediction functionalities. Hierarchical clustering phylogenetic analysis further elucidated between clans, uncovering shared deep history. explored distribution subfamilies algal lineages, novel candidates providing insights evolution these This identified unexpected such CYP82 CYP74, shedding light roles defense signaling pathways. Our approach provides a methodology brings emergence new functions CYP450 family, contributing algae. These can be validated implemented via experimental setups under various external conditions.

ABSTRACT Streptofilum capillatum was recently described and immediately caught scientific attention, because it forms a phylogenetically deep branch in the streptophytes is characterised by unique cell coverage composed of piliform scales. Its phylogenetic position taxonomic rank are still controversial discussed. In present study, we isolated further strains from biocrusts sand dunes Arctic tundra soil. Molecular morphological characterisation including transmission electron microscopy confirmed that both new belong to .
