Abstract Cytokinins play crucial roles in diverse aspects of plant growth and development. Spatiotemporal distribution bioactive cytokinins is finely regulated by metabolic enzymes. LONELY GUY (LOG) was previously identified as a cytokinin-activating enzyme that works the direct activation pathway rice (Oryza sativa) shoot meristems. In this work, nine Arabidopsis thaliana LOG genes (At LOG1 to LOG9) were predicted homologs LOG. Seven At LOGs, which are localized cytosol nuclei, had...
Inflorescence structures result from the activities of meristems, which coordinate both renewal stem cells in center and organ formation at periphery. The fate a meristem is specified its initiation changes as plant develops. During rice inflorescence development, newly formed meristems acquire branch (BM) identity, can generate further or terminate spikelets. Thus, form determined by reiterative pattern decisions made meristems. In dominant gain-of-function mutant tawawa1-D , activity (IM)...
Cytokinins are phytohormones that play key roles in the maintenance of stem cell activity plants. Although alternative single-step and two-step activation pathways for cytokinin have been proposed, significance pathway which is catalyzed by LONELY GUY (LOG), not fully understood. We analyzed metabolic flow Arabidopsis log multiple mutants using stable isotope-labeled tracers characterized mutants' morphological developmental phenotypes. In tracer experiments, was inhibited most pronouncedly...
Abstract cis-Zeatin (cZ) is generally regarded as a cytokinin with little or no activity, compared the highly active trans-zeatin (tZ). Although recent studies suggested possible roles for cZ, its physiological significance remains unclear. In our rice (Oryza sativa), cZ inhibited seminal root elongation and up-regulated cytokinin-inducible genes, activities were comparable to those of tZ. Tracer experiments showed that exogenously supplied cZ-riboside was mainly converted into derivatives...
Automated digital histopathology image segmentation is an important task to help pathologists diagnose tumors and cancer subtypes. For pathological diagnosis of subtypes, usually change the magnification whole-slide images (WSI) viewers. A key assumption that importance magnifications depends on characteristics input image, such as In this paper, we propose a novel semantic method, called Adaptive-Weighting-Multi-Field-of-View-CNN (AWMF-CNN), can adaptively use features from with different...
In Asia, cassava (Manihot esculenta) is cultivated by more than 8 million farmers, driving the rural economy of many countries. The International Center for Tropical Agriculture (CIAT), in partnership with national agricultural research institutes (NARIs), instigated breeding and agronomic 1983. program has successfully released high-yielding cultivars resulting an average yield increase from 13.0 t ha–1 1996 to 21.3 2016, significant economic benefits. Following success increasing yields,...
Abstract Axis formation is a fundamental issue in developmental biology. and patterning plant leaves crucial for morphology crop productivity. Here, we reveal the basis of proximal-distal rice leaves, which consist proximal sheath, distal blade, boundary organs formed between these two regions. Analysis three homologs Arabidopsis BLADE-ON-PETIOLE1 ( BOP1 ) gene indicates that OsBOPs activate sheath differentiation suppress blade differentiation. Temporal expression changes are responsible...
Cassava (Manihot esculenta Crantz) is a root crop grown in tropical and subtropical regions. production faces an increasing number of new diseases arthropod pests, especially Southeast Asia, where its area trade have expanded. An efficient plant-multiplication system required to provide disease-free plants farmers sustain production. generally propagated vegetatively by planting properly lignified stem cuttings soil. Vegetative multiplication simple approach has the advantage producing...
The optical properties of the sandwich Ag nanorod array (NRA)/structured dielectric layer/Ag mirror have been investigated theoretically and experimentally, where structured layer has stacked sublayers an anisotropic nanocolumnar a uniform layer. functions are to control shape nanorods tune path length inside sandwich, respectively. Calculations based on simple model by treating NRAs as effective media indicate that antireflection condition is realized changing thickness absorb most incident...
We improved the photovoltaic properties of Cu2O-based heterojunction solar cells using n-type oxide semiconductor thin films prepared by a sputtering apparatus with our newly developed multi-chamber system. also obtained highest efficiency (3.21%) in an AZO/p-Cu2O cell optimized pre-sputtering conditions This value achieves same or higher characteristics than AZO/Cu2O similar structure pulse laser deposition method.
This paper describes the influence of electron scattering from disordered grain boundaries on carrier transport in polycrystalline Al‐doped ZnO (AZO) thin films prepared with concentrations order 10 20 cm −3 . It is found that degenerate AZO glass substrates by various magnetron sputtering depositions, mobility–carrier concentration ( µ Hall – n ) relationship a positive slope increases as increases) always obtained when measured changing sputter gas pressure and substrate temperature,...
A novel noncollagenous acidic protein was identified from the scales of goldfish (Carassius auratus), a freshwater teleost. Using an in vitro calcium phosphate crystallization assay, EDTA-soluble fraction these screened for inhibitory activity, and highly phosphorylated glycoprotein, named scale (GSP)-37, isolated through 5 HPLC purification steps. The cDNA GSP-37 has open reading frame encoding precursor protein, consisting signal peptide GSP-37, with 19 137 amino acid residues,...
Abstract A novel chiral polyimine macrocycle C‐1 was designed and synthesized by the self‐condensation of dialdehyde dinaphtho[ 2,1‐d:1′,2′‐f ][1,3]dioxepine derivative o ‐phenylenediamine Schiff base formation, corresponding polyamine C‐1H obtained reduction macrocycle. The UV–vis fluorescence spectral studies indicated that both form complex with metal ions in a 1:2 ratio. behaviour upon addition Zn 2+ or Cd showed ‘turn‐on’ response accompanied enhancement at 510 nm six times for 13 . In...
Segmentation is a fundamental process in biomedical image analysis that enables various types of analysis. Segmenting organs histological microscopy images problematic because the boundaries between regions are ambiguous, have appearances, and amount training data limited. To address these difficulties, supervised learning methods (e.g., convolutional neural networking (CNN)) insufficient to predict accurately they usually require large learn appearances. In this paper, we propose...
