Abstract Microbial arsenic (As) methylation and demethylation are important components of the As biogeochemical cycle. Arsenic is enhanced under flooded conditions in paddy soils, producing mainly phytotoxic dimethylarsenate (DMAs) that can cause rice straighthead disease, a physiological disorder occurring widely some growing regions. The key microbial groups responsible for soils unknown. Three were incubated conditions. DMAs initially accumulated soil porewater, followed by rapid...
Microbe-mediated arsenic (As) redox reactions play an important role in the biogeochemical cycling of As. Reduction arsenate [As(V)] generally leads to As mobilization paddy soils and increased availability rice plants, whereas oxidation arsenite [As(III)] results immobilization. A novel chemoautotrophic As(III)-oxidizing bacterium, designated strain SY, was isolated from As-contaminated soil. The isolate able derive energy As(III) As(V) under both aerobic anaerobic conditions using O2 or...
Plant roots rely on inorganic orthophosphate (Pi) transporters to acquire soluble Pi from soil solutions that exists at micromolar levels in natural ecosystems. Here, we functionally characterized a rice (Oryza sativa) transporter, Os Phosphate Transporter-1;3 (OsPHT1;3), mediates uptake, translocation, and remobilization. OsPHT1;3 was directly regulated by Starvation Response-2 and, response starvation, showed enhanced expression young leaf blades shoot basal regions even more so old...
Arsenic (As) bioavailability to rice plants is elevated in flooded paddy soils due reductive mobilization of arsenite [As(III)]. However, some microorganisms are able mediate anaerobic As(III) oxidation by coupling nitrate reduction, thus attenuating As mobility. In this study, we investigated the impact additions on species dynamics porewater four As-contaminated soils. The effects microbial community structure and abundance diversity oxidase (aioA) genes were quantified using 16S rRNA...
Long-term strain improvements through repeated mutagenesis and screening have generated a hyper-producer of cellulases hemicellulases from Penicillium decumbens 114 which was isolated 30 years ago. Here, the genome P. JU-A10-T sequenced compared with that wild-type 114-2. Further, transcriptomes secretomes were between strains. Selective hyper-production but not all secreted proteins observed in mutant, making it more specific producer lignocellulolytic enzymes. Functional analysis...
Microbial arsenic (As) methylation and volatilization are important processes controlling the As biogeochemical cycle in paddy soils. To further understand these processes, we isolated a novel bacterial strain, SM-1, from an As-contaminated soil. SM-1 showed strong abilities, converting almost all arsenite (10 μM) to dimethylarsenate trimethylarsenic oxide medium trimethylarsine gas into headspace within 24 h, with accounting for nearly half of total As. On basis 16S rRNA sequence, strain...
Inorganic arsenic (As) is highly toxic and ubiquitous in the environment. As can be transformed by microbial methylation, which constitutes an important part of biogeochemical cycle. In this study, we investigated biotransformation Pseudomonas alcaligenes NBRC14159. P. was able to methylate arsenite [As(III)] rapidly dimethylarsenate small amounts trimethylarsenic oxide. An S-adenosylmethionine methyltransferase, PaArsM, identified functionally characterized. PaArsM shares low similarities...
The adaptive responses of plants to phosphate (Pi) starvation stress are fine-tuned by an elaborate regulatory network. In this study, we identified and characterized a novel Pi starvation-responsive gene, MYB1, encoding R2R3-type transcription factor in rice. MYB1 was transcriptionally induced leaf sheaths old blades. It localized the nucleus expressed mainly vascular tissues. Mutation led increase uptake accumulation, accompanied altered expression subset transporters several genes...
Abstract In plants, cytosine DNA methylations (5mCs) can happen in three sequence contexts as CpG, CHG, and CHH (where H = A, C, or T), which play different roles the regulation of biological processes. Although long Nanopore reads are advantageous detection 5mCs comparing to short-read bisulfite sequencing, existing methods only detect CpG context, limits their application plants. Here, we develop DeepSignal-plant, a deep learning tool genome-wide all plants from reads. We Arabidopsis...
Abstract Recently, observational hints for supermassive black holes have been accumulating, prompting the question: Can primordial (PBHs) be supermassive, particularly with masses M ≳ 10 9 ⊙ ? A supercritical bubble, containing an inflating baby universe, that nucleated during inflation can evolve into a PBH in our observable universe. We find when inflaton slowly transitions past neighboring vacuum, nucleation rate of bubbles inevitably peaks, leading to mass distribution multiverse PBHs...
A butachlor-degrading strain, designated FLY-8, was isolated from rice field soil and identified as Paracoccus sp. Strain FLY-8 could degrade utilize six chloroacetamide herbicides carbon sources for growth, the degradation rates followed order alachlor > acetochlor propisochlor butachlor pretilachlor metolachlor. The influence of molecular structure on microbial rate first analyzed; results indicated that substitutions alkoxymethyl side chain with alkoxyethyl greatly reduced efficiencies;...
Plant Phosphate Transporter 1 (PHT1) proteins, probably the only influx transporters for phosphate (Pi) uptake, are partially degraded on sufficient Pi levels to prevent excessive accumulation. Therefore, basal/constitutive expression level of PHT1 genes is vital maintaining uptake under Pi-replete conditions. Rice (Oryza sativa) OsPHT1;1 a unique gene as it highly expressed and not responsive Pi, however mechanism its remains unknown. Using biochemical genetic approaches, we identified...
Summary Arsenic (As) biomethylation is an important component of the As biogeochemical cycle that can influence toxicity and mobility in environment. Biomethylation catalyzed by enzyme arsenite (As[III]) S ‐adenosylmethionine methyltransferase (ArsM). To date, all identified ArsM orthologs with As(III) methylation activities have four conserved cysteine residues, which are thought to be essential for methylation. Here, we isolated As(III)‐methylating bacterium, Bacillus sp. CX‐1, a gene...
