Significance Fossil evidence shows that red algae (Rhodophyta) are one of the most ancient multicellular lineages. Their ecological, evolutionary, and commercial importance notwithstanding, few algal nuclear genomes have been sequenced. Our analyses Porphyra umbilicalis genome provide insights into how this macrophyte thrives in stressful intertidal zone basis for its nutritional value as human food. Many novel traits (e.g., cytoskeletal organization, calcium signaling pathways) we find...
Abstract Intracellular recycling via autophagy is governed by post-translational modifications of the autophagy-related (ATG) proteins. One notable example ATG4-dependent delipidation ATG8, a process that plays critical but distinct roles in autophagosome formation yeast and mammals. Here, we aim to elucidate specific contribution this species representative evolutionarily distant green plant lineages: unicellular alga Chlamydomonas reinhardtii , with relatively simple set ATG genes,...
Cryptochromes are flavin-binding proteins that act as blue light receptors in bacteria, fungi, plants, and insects components of the circadian oscillator mammals. Animal plant cryptochromes evolutionarily divergent, although unicellular alga Chlamydomonas reinhardtii (Chlamydomonas throughout) has both an animal-like cryptochrome a (pCRY; formerly designated CPH1). Here, we show pCRY protein accumulates at night part complex. Functional characterization was performed based on insertional...
Cryptochromes are known as flavin-binding blue light receptors in bacteria, fungi, plants, and insects. The animal-like cryptochrome (aCRY) of the green alga Chlamydomonas reinhardtii has extended our view on cryptochromes, because it responds also to other wavelengths visible spectrum, including red light. Here, we have investigated if aCRY is involved regulation sexual life cycle C. reinhardtii, which controlled by at steps gametogenesis along with its restoration germination. We show that...
Horizontal gene transfer (HGT) is traditionally considered to be rare in multicellular eukaryotes such as animals. Recently, many genes of miscellaneous algal origins were discovered choanoflagellates. Considering that choanoflagellates are the existing closest relatives animals, we speculated ancient HGT might have occurred unicellular ancestor animals and affected long-term evolution animals.Through genome screening, phylogenetic domain analyses, identified 14 families, including 92 genes,...
Abstract Ring‐moat dome structures (RMDSs) are small circular mounds of diameter typically about 200 m and ∼3–4 in height, surrounded by narrow, shallow moats. They occur clusters, widespread ancient Imbrian‐aged mare basalt host units show mineralogies comparable to those their units. Based on these close associations similarities, a model has been proposed for the formation RMDS as result late‐stage flow inflation, with second boiling releasing quantities magmatic volatiles that migrate...
Activated carbons from Chinese coals have been prepared by chemical activation technology with potassium hydroxide. This paper analyzed the following aspects: raw material and its particle size, preoxidation treatment of material, agent, temperature time, agent/coal ratio. carbon BET N2 surface area order 2400 m2/g, substantal microporosity total pore volume over 1.40 cm3/g, methylene blue adsorption capacity 440 mg/g, was obtained.
Abstract Ring‐moat dome structures (RMDSs) are positive morphologic features found clustered across many mare regions on the Moon, of which only a few isolated examples have been previously reported. Our continuing survey has expanded known locations RMDSs from ~2,600 to over 8,000, indicating that more common geological than thought. This work presents detailed geomorphological analysis 532 identified in several basins. The combination elemental mapping, morphological and morphometric...
Proteases can regulate myriad biochemical pathways by digesting or processing target proteins. While up to 3% of eukaryotic genes encode proteases, only a tiny fraction proteases are mechanistically understood. Furthermore, most the current knowledge about is derived from studies few model organisms, including Arabidopsis thaliana in case plants. other plant systems largely unexplored territory, limiting our mechanistic comprehension post-translational regulation plants and hampering...
Caspases are restricted to animals, while other organisms, including plants, possess metacaspases (MCAs), a more ancient and broader class of structurally related yet biochemically distinct proteases. Our current understanding plant MCAs is derived from studies in streptophytes, mostly Arabidopsis (Arabidopsis thaliana) with 9 partially redundant activities. In contrast most chlorophytes contain only 1 or 2 uncharacterized MCAs, providing an excellent platform for MCA research. Here we...
As a part of our continuing research on amine derivative antifungal agents, 19 novel target compounds containing 1,2,4-triazole and tertiary moieties were designed synthesized, their in vitro activities against six phytopathogenic fungi (Magnaporthe grisea, Alternaria solani, Fusarium Curvularia lunata, A. alternata, F. graminearum) assayed. All elucidated by means 1H-NMR, 13C-NMR, high resolution (HR)-MS, IR analysis. The results showed that most the derivatives exhibited obvious activity...
Being shaded is a common environmental stress for plants, especially densely planted crops. Shade decreases red: far-red (R:FR) ratios that inactivate phytochrome B (PHYB) and subsequently release p̱hytochrome i̱nteraction f̱actors (PIFs). Shaded plants display elongated hypocotyls, internodes, petioles, hyponastic leaves, early flowering are inhibited in branching: traits collectively called the shade avoidance syndrome (SAS). ZEITLUPE (ZTL) circadian clock component blue light...
Microalgae contribute significantly to carbon fixation on Earth. Global warming influences their physiology and growth rates. To understand algal short-term acclimation adaptation changes in ambient temperature, it is essential identify characterize the molecular components that sense small temperature as well downstream signaling networks physiological responses. Here, we used green biflagellate alga Chlamydomonas reinhardtii a model system which study responses temperature. We report an...

The sequence diversities in three mitochondrial DNA (mtDNA) regions, namely portions of NADH dehydrogenase subunit 1 (pnad1), cytochrome c oxidase (pcox1), and 4 (pnad4), were investigated all Ascaris suum samples isolated from four regions northwestern China. Those genes amplified by PCR method the lengths pnad1, pcox1, pnad4 419 bp, 711 723 respectively. intraspecific variations within A. 0–2.9% for 0–2.1% 0–3.1% pnad4. Phylogenetic analysis combined with sequences mtDNA fragments showed...
Under hydrothermal conditions, a new two-dimensional (2D) zinc coordination polymer, [Zn(tdc)(bimm)]n, was synthesized based on thiophene-2,5-dicarboxylic acid (H2tdc) and 1,2-bis(imidazol-1′-yl)methane (bimm) mixed ligands. Single crystal X-ray structural analysis shows adjacent Zn2+ ions are connected by tdc2− anions to form one-dimensional (1D) [ZnL]n chain in the complex. Then flexible bimm ligands expand 1D chains into 2D layer linking neighboring ions. These layers further stacked...
Abstract Caspases are restricted to animals, while other organisms, including plants possess metacaspases (MCAs), a more ancient and broader class of structurally-related yet biochemically distinct proteases. Our current understanding plant MCAs is derived from studies in streptophytes, mostly Arabidopsis expressing nine with partly redundant activities. In contrast most chlorophytes contain only one or two hitherto uncharacterized MCAs, providing an excellent platform for MCA research. Here...
