We report improved whole-genome shotgun sequences for the genomes of indica and japonica rice, both with multimegabase contiguity, or almost 1,000-fold improvement over drafts 2002. Tested against a nonredundant collection 19,079 full-length cDNAs, 97.7% genes are aligned, without fragmentation, to mapped super-scaffolds one other genome. introduce gene identification procedure plants that does not rely on similarity known remove erroneous predictions resulting from transposable elements....
Significance A wide range of organisms sense Earth’s magnetic field for navigation. For some organisms, like magnetotactic bacteria, particles form inside cells and act a compass. However, the origin behavior remains mystery. We report that magnetotaxis evolved in bacteria during Archean, before or near divergence between Nitrospirae Proteobacteria phyla, suggesting are one earliest magnetic-sensing biomineralizing on Earth. The early would have provided evolutionary advantages coping with...
Abstract The origin and evolution of magnetoreception, which in diverse prokaryotes protozoa is known as magnetotaxis enables these microorganisms to detect Earth’s magnetic field for orientation navigation, not well understood evolutionary biology. only capable sensing the geomagnetic are magnetotactic bacteria (MTB), motile that biomineralize intracellular, membrane-bounded single-domain crystals either magnetite (Fe3O4) or greigite (Fe3S4) called magnetosomes. Magnetosomes responsible...
In this report, we describe the selective cloning of large DNA fragments from magnetotactic metagenomes various aquatic habitats. This was achieved by a two-step magnetic enrichment which allowed mass collection environmental bacteria (MTB) virtually free nonmagnetic contaminants. Four fosmid libraries were constructed and screened end sequencing hybridization analysis using heterologous magnetosome gene probes. A total 14 fosmids fully sequenced. We identified characterized two fosmids,...
Human coronavirus OC43 (HCoV-OC43) is one of five currently circulating human coronaviruses responsible for respiratory infections. Like all coronaviruses, it characterized by its genome’s high plasticity. The objectives the current study were to detect genetically distinct genotypes and eventually recombinant in samples collected Lower Normandy between 2001 2013. To this end, we sequenced complete nsp12, S, N genes 15 molecular isolates HCoV-OC43 from clinical compared them available data...
Male infertility accounts for almost half of cases worldwide. A subset infertile men exhibit reduced testosterone and enhanced levels estradiol (E2), though it is unclear how increased E2 promotes deterioration male fertility. Here, we utilized a transgenic mouse strain that overexpresses human CYP19, which encodes aromatase (AROM+ mice), mice with knockout Esr1, encoding estrogen receptor α (ERαKO to analyze interactions between viable Leydig cells (LCs) testicular macrophages may lead...
Abstract A broad range of organisms, from prokaryotes to higher animals, have the ability sense and utilize Earth's geomagnetic field—a behavior known as magnetoreception. Although our knowledge physiological mechanisms magnetoreception has increased substantially over recent decades, origin this remains a fundamental question in evolutionary biology. Despite this, there is growing evidence that magnetic iron mineral biosynthesis by may represent earliest form biogenic sensors on Earth....
Abstract Background The discovery of membrane-enclosed, metabolically functional organelles in Bacteria has transformed our understanding the subcellular complexity prokaryotic cells. Biomineralization magnetic nanoparticles within magnetosomes by magnetotactic bacteria (MTB) is a fascinating example organelles. Magnetosomes, as nano-sized sensors MTB, facilitate cell navigation along local geomagnetic field, behaviour referred to magnetotaxis or microbial magnetoreception. Recent novel MTB...
Abstract As the largest basin on Mars, Utopia Planitia has both experienced and recorded variations of Martian palaeoclimate. Layered subsurface structures have been identified by ground-penetrating radar in southern but lateral subsurface, potentially linked to palaeoclimatic evolution, not investigated. Here we report frequency-variation patterns Zhurong reflections interpret them as buried polygonal terrain below a depth 35 m. Sixteen wedges were within ∼1.2 km distance, suggesting wide...
Stable single-domain (SD) magnetite formed intracellularly by magnetotactic bacteria is of fundamental interest in sedimentary and environmental magnetism. In this study, we studied the time course magnetosome growth chain formation (0–96 hr) Magnetospirillum magneticum AMB-1 transmission electron microscopy (TEM) observation rock The initial non-magnetic cells were microaerobically batch cultured at 26 °C a modified magnetic spirillum medium. TEM observations indicated that between 20 24 hr...
'Candidatus Magnetobacterium bavaricum' is unusual among magnetotactic bacteria (MTB) in terms of cell size (8-10 µm long, 1.5-2 diameter), architecture, behaviour and its distinct phylogenetic position the deep-branching Nitrospira phylum. In present study, improved magnetic enrichment techniques permitted high-resolution scanning electron microscopy energy dispersive X-ray analysis, which revealed intracellular organization magnetosome chains. Sulfur globule accumulation cytoplasm point...
ABSTRACT Magnetotactic bacteria (MTB) in the phylum Nitrospirae synthesize up to hundreds of intracellular bullet-shaped magnetite magnetosomes. In present study, a watermelon-shaped magnetotactic bacterium (designated MWB-1) from Lake Beihai Beijing, China, was characterized. This uncultivated microbe identified as member and represents novel phylogenetic lineage with ≥6% 16S rRNA gene sequence divergence all currently described MTB. MWB-1 contained 200 300 magnetosomes showed helical...
Microorganisms play key roles in biogeochemical and nutrient cycling all ecosystems on Earth, yet little is known about the processes controlling their biogeographic distributions. Here we report an investigation of magnetotactic bacteria (MTB) designed to evaluate niche-based process spatial explaining variation bacterial communities across large scales. Our results show that both environmental heterogeneity geographic distance significant shaping dominant populations MTB community...
In the present study, we investigated a group of uncultivated magnetotactic cocci, which was magnetically isolated from freshwater pond in Beijing, China. Light and transmission electron microscopy showed that these cocci ranged 1.5 to 2.5 microm contained two four chains magnetite magnetosomes, sometimes were partially disorganized. Overall, size disorganized magnetosomes significantly smaller than arranged chains. All characterized magnetosome crystals elongated (shape factor = 0.64) fall...
Sorting is a kernel algorithm for wide range of applications. In this paper, we present new algorithm, GPU-Warpsort, to perform comparison-based parallel sort on Graphics Processing Units (GPUs). It mainly consists bitonic followed by merge sort. Our achieves high performance efficiently mapping the sorting tasks GPU architectures. Firstly, take advantage synchronous execution threads in warp eliminate barriers network. We also provide sufficient homogeneous operations all within avoid...
Summary The intracellular biomineralization of magnetite and/or greigite magnetosomes in magnetotactic bacteria ( MTB ) is strictly controlled by a group conserved genes, termed magnetosome which are organized as clusters (or islands) genomes. So far, all reported affiliated within the P roteobacteria phylum, N itrospirae phylum and candidate division OP 3. Here, we report discovery putative gene cluster structure from draft genome an uncultivated bacterium belonging to L atescibacteria...
