Abstract RNA N 6 ‐methyladenine (m A) modification represents a pivotal epigenetic that facilitates the remodeling of gene expression and regulates variety biological processes via certain post‐transcriptional mechanisms. However, specific function m A in insect male reproduction remains unclear. In this study, we explored molecular mechanism by which METTL3/METTL14‐mediated invasive pest Bactrocera dorsalis . The results showed BdMettl3 BdMettl14 were highly expressed fat body (FB)...

Genes on the Y chromosome play important roles in male sex determination and development. The identification of Y-chromosome-specific genes not only provides a theoretical basis for study reproductive development, but also offers genetic control targets agricultural pests. However, Y-chromosome are rarely characterized due to their high repeatability heterochromatinization, especially oriental fruit fly. In this study, 1 011 candidate sequences were screened from 2 4 h Bactrocera dorsalis...

Introduction: Zeugodacus tau (Walker) is an invasive pest. An effective method to control this pest the sterile insect technique (SIT). To better apply technique, it necessary understand testis development progression. Methods: Differentially expressed genes (DEGs) during were analyzed by PacBio Iso-Seq and RNA-seq. Results: RNA-Seq library of Z. testes on day 1, 6, 11 post eclosion constructed. We identified 755 865 differentially in comparisons T6 (testes 6) vs. T1 T11 T1, respectively....

With high porosity and being one of the most abundant clay minerals, dried kaolinite may be an excellent adsorbent to remove ammonia gas (NH3). Here, plane wave pseudopotential method based on density functional theory (DFT) was used explore mechanism adsorption kaolinite, Mulliken electric charge, partial states atoms NH3/kaolinite (001) system. NH3 can happen in three different type positions: “top”, “bridge” “hollow”. The “hollow” position is enclosed by two "upright" hydroxyl groups...

Single-crystal diamond stands out among all the candidate materials that could be exploited to fabricate compound refractive lenses (CRLs) owing its extremely stable properties. Among related experimental features, beam divergence, χ-angles relative incoming in Eulerian geometry and different positions of X-ray lens may influence transmission energy spectrum CRLs. In addition, orientation single-crystal sample also affect glitches significantly. To verify these initial assumptions, two...

Based on classical radiation theory, the electron relativistic dynamics, full spatial and spectral characteristics of nonlinear Thomson scattering in a linearly polarized intense few-cycle laser pulse have been investigated theoretically numerically. In pulse, dynamics depends sensitively initial phase driving pulse. The also shows many remarkable phase-sensitive characteristics. For most phases, x–y plane y–z symmetry angular distributions is broken down, i.e., well-known fourfold...

Non-invasive genotyping methods provide valuable information on insect populations. However, poor DNA amplification and time-consuming sampling procedures limit these methods, especially for small insects. An efficient convenient method was developed non-invasive, non-lethal of a large insect, Mythimna separata, Drosophila melanogaster, by endogenous exogenous, nuclear mitochondrial genes from frass, exuviae, food waste. For M. the chitin synthesis gene MsCHSB COI were successfully detected...

Nickel sulfide minerals, an important type of metal sulfides, are the major component mantle sulfides. They also one windows for partial melting, metasomatism, and fluid mineralization. The elasticity plays role in understanding deformation elastic wave propagation it is key parameter interpreting seismic velocity terms composition Earth’s interior. Based on first-principles methods, crystal structure, equation state, constants, modulus, mechanical stability, anisotropy, millerite (NiS),...

Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to "CRLs") mainly due its stability when bathed in strong X-ray radiation. Since CRLs come into operation by a mechanism, it imperative study the transmission spectrum carefully. Many factors may influence spectrum, including experimental features (such beam divergence) and crystal orientation this case. To verify initial assumptions, two setups were realized - energy scan ω-scan....

Abstract Gut commensal bacteria promote host reproduction by modulating metabolism and nutrition, yet the molecular mechanisms which microbes modulate remain unclear. Here, we show that gut providing amino-acid methionine, controls RNA m6A modification level of insulin receptor ( InR ) in ovary invasive insect Bactrocera dorsalis . levels S-adenosyl-methionine (SAM) titers ovaries were sharply reduced antibiotic treated B. compared with untreated insects, resulting arrested ovarian...

Abstract In the organisms with XX/XY sex chromosomes, Y chromosome is unique to males and plays an important role in male reproductive development. The study of genes will contribute development pest genetic prevention control technology. this study, we identified 9 Zeugodacus tau (Diptera: Tephritidae), including gene 16222 . Protein structure analysis showed that was highly similar odorant binding protein, thus named obp‐Y Obp‐Y knockout (KO) significantly reduced hatching rate offspring....

Abstract BACKGROUND In many organisms, the Y chromosome contains important genes associated with sex determination and male reproductive development. However, there have been few studies of Y‐chromosome‐specific in non‐model species due to incomplete information genome difficulty sequencing. Here, we screened 90 candidate Y‐specific sequences a constructed transcriptome assembly library by using quotient method, among which 11 were unreported development, including Bactrocera dorsalis...

Spatial characteristics of radiation generated from electron oscillations driven by circularly polarized femtosecond laser pulses have been investigated theoretically and numerically using a single model. It is discovered that the radiated power approximately same in all directions for driver with low intensities directed toward direction propagation narrower divergence tipped forward more increase intensity. The full spatial emission can be exploited to measure intensity experiment.
