Sediment Characteristics in Stonewort <i>Chara Tomentosa</i> Assemblages. [PDF]

Ecol Evol
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.

Metagenomic analysis of the gut microbiota of hooded cranes (Grus monacha) on the Izumi plain in Japan. [PDF]

FEBS Open Bio
We analyzed metagenomic sequencing data obtained from fecal samples of hooded cranes and wild ducks that winter on the Izumi Plain in Japan. Various organisms were identified in each sample, and their diversity differs between the crane and duck groups, suggesting that these two bird species may have distinct gut microbiota.

Mathematical analysis of long-distance polar auxin transport data of pin mutants questions the role of PIN1 as postulated in the chemi-osmotic theory. [PDF]

Physiol Plant
Abstract The plant hormone auxin (Indole‐3‐Acetic Acid, IAA) is a key player in nearly every aspect of plant growth and development ranging from cell division and cell elongation to embryogenesis and root formation. The IAA level in specific tissues and cells is regulated by synthesis, conjugation, degradation and transport. Especially long‐range polar

New distributional records, taxonomy, morphology, and genetic variations of the endangered brackish-water species Lamprothamnium succinctum (Charales: Charophyceae) in Japan

Journal of Asia-Pacific Biodiversity, 2021
Members of the brackish-water species Lamprothamnium succinctum (Charales, Charophyceae) are widely distributed from tropical to temperate regions, including East Asia. In Japan, L.

Cell wall-related glycosyltransferases and wall architecture in the model liverwort Marchantia polymorpha. [PDF]

Plant J
SUMMARY The liverwort Marchantia polymorpha has emerged as an important plant model for developmental studies and may become central to elucidate the complex process of cell wall polysaccharide biosynthesis. This study comprehensively analyses the composition and structure of cell wall glycans across eight different M. polymorpha tissue types.

Paleometagenomics reveals environmental microbiome response to vegetation changes in northern Siberia over the millennia

Environmental DNA, Volume 5, Issue 6, Page 1252-1264, November 2023., 2023
We integrated taxonomic with functional gene analysis, which enabled to shed light not only on community compositions but also on long‐term eco‐physiological adaptations and ecosystem functioning. Various genes coding enzymes responsible for biomass degradation, carbon metabolism, and adaptation to environmental stress were identified and traced over ...

Insight into the nodal cells transcriptome of the streptophyte green alga Chara braunii S276

Physiologia Plantarum, Volume 175, Issue 5, September/October 2023., 2023
Abstract Charophyceae are the most complex streptophyte algae, possessing tissue‐like structures, rhizoids and a cellulose‐pectin‐based cell wall akin to embryophytes. Together with the Zygnematophyceae and the Coleochaetophycae, the Charophyceae form a grade in which the Zygnematophyceae share a last common ancestor with land plants.

The cell walls of different Chara species are characterized by branched galactans rich in 3‐O‐methylgalactose and absence of AGPs

Physiologia Plantarum, Volume 175, Issue 4, July/August 2023., 2023
Abstract Streptophyte algae are the closest relatives to land plants; their latest common ancestor performed the most drastic adaptation in plant evolution around 500 million years ago: the conquest of land. Besides other adaptations, this step required changes in cell wall composition.

Mesopredator‐mediated trophic cascade can break persistent phytoplankton blooms in coastal waters

Oikos, Volume 2023, Issue 4, April 2023., 2023
Managing eutrophied systems using only nutrient decreases to impose bottom–up control can be economically and ecologically challenging. Top–down controls through increased consumption have sometimes effectively controlled phytoplankton blooms. However, mechanistic insights, especially on possible trophic cascades, are less understood in brackish ...

Origin of land plants: Do conjugating green algae hold the key?

BMC Evolutionary Biology, 2011
Background The terrestrial habitat was colonized by the ancestors of modern land plants about 500 to 470 million years ago. Today it is widely accepted that land plants (embryophytes) evolved from streptophyte algae, also referred to as charophycean ...
