Beneficial and biocontrol effects of , a dominant species in white birch rhizosphere soil.

White birch ( Suk.) is a typical pioneer tree species that is important in forest restoration in northern China, Japan, and Korea. In the present study, 37 isolates were obtained from rhizosphere soils in Heilongjiang Province; they were identified as (3 isolates), (2 isolates), (8 isolates), (21 isolates, dominant species) and (3 isolates).

Divergence of trafficking and polarization mechanisms for PIN auxin transporters during land plant evolution.

The phytohormone auxin, and its directional transport through tissues, plays a fundamental role in the development of higher plants. This polar auxin transport predominantly relies on PIN-FORMED (PIN) auxin exporters. Hence, PIN polarization is crucial for development, but its evolution during the rise of morphological complexity in land plants remains unclear.

Origin of p-type conductivity in a WSe monolayer.

Transition-metal dichalcogenides have promising potentials for high-performance electronic and optoelectronic applications, which could be deeply influenced by defects, including native defects and dopants. Experiments to date have frequently reported p-type conductivity in the WSe monolayer, but the origin remains elusive. Here, using the first-principles calculations, we systematically investigate the point defects in the WSe monolayer and show that: (1) no intrinsic point defect is responsible for the p-type doping; (2) hydrogen interstitials (H) are possible sources for n-type conductivity; (3) oxygen substitution of Se (O) can greatly promote the formation of adjacent W vacancy (V), and finally make V relatively shallow acceptors by forming the defect complex O + V ( = 1 to 6).

Analysis of the Properties of 44 ABC Transporter Genes from Biocontrol Agent ACCC30536 and Their Responses to Pathogenic Toxin Stress.

ATP-binding cassette (ABC) transporters are involved in transporting multiple substrates, such as toxins, and may be important for the survival of when encountering biotic toxins. In this study, genome searching revealed that there are 44 ABC transporters encoded in the genome of . These ABC transporters were divided into six types based on three-dimensional (3D) structure prediction, of which four, represented by 39 ABCs, are involved in transport and the remaining two, represented by 5 ABCs, are involved in regulating translation.

Color medical image cryptography technology based on segmentation and fractional-order hyperchaotic system.

This paper proposes a novel color medical image encryption method based on mean shift algorithm and fractional-order hyperchaotic system. Firstly, color medical images were divided into lesion area, detection area, and edge area by using mean shift clustering. Low-value pixels and zero-value pixels in the edge region are abandoned to improve the encryption efficiency.

Amantadine, a promising therapeutic agent against viral encephalopathy and retinopathy.

Outbreaks of viral encephalopathy and retinopathy (VER) in marine and freshwater species severely devastate the aquaculture worldwide. The causative agent of VER is nervous necrosis virus (NNV), which mainly infects the early developmental stages of fish, limiting the effectiveness of vaccines. To counter this case, the anti-NNV potentials of nine drugs with broad-spectrum antiviral activity were explored using ribavirin as a positive drug.

Analysis of nicotine-induced metabolic changes in Blakeslea trispora by GC-MS.

Blakeslea trispora is a natural source of carotenoids, including β-carotene and lycopene, which have industrial applications. Therefore, classical selective breeding techniques have been applied to generate strains with increased productivity, and microencapsulated β-carotene preparation has been used in food industry (Li et al., 2019).

Comparative Metabolic Responses Induced by Pyridine and Imidazole in .

Lycopene cyclase needs to be inhibited by the blockers like pyridine or imidazole in the lycopene accumulation of . This work investigated how pyridine and imidazole impacted the basal metabolism of , the results helped us understand how they could affect the lycopene production and application, and see the metabolic risks from different inhibitors. In this study, the highest yield of lycopene with pyridine was obtained at 176 mg/L without amino acids supplement, and got more lycopene at 237 mg/L adding tyrosine, lysine, proline all together as 0.

Identification, characterization, and functional studies of a Pelle gene in the Chinese mitten crab, Eriocheir sinensis.

The toll-like receptor/NF-κB signaling pathways play an important role in the innate immune system. In the present study, one Pelle gene (named EsPelle) was identified for the first time from the Chinese mitten crab Eriocheir sinensis. The full-length cDNA of EsPelle is 3797 bp with a 3156 bp-long open reading frame that encodes a 1051 amino acid protein.

[Hard and soft classification method of multi-spectral remote sensing image based on adaptive thresholds].

Hard and soft classification techniques are the conventional methods of image classification for satellite data, but they have their own advantages and drawbacks. In order to obtain accurate classification results, we took advantages of both traditional hard classification methods (HCM) and soft classification models (SCM), and developed a new method called the hard and soft classification model (HSCM) based on adaptive threshold calculation. The authors tested the new method in land cover mapping applications.

Polymorphism of the D4Z4 locus associated with facioscapulohumeral muscular dystrophy 1A in Shanghai population.

Objective: To investigate the D4Z4 repeats on chromosome 4q35 in normal individuals in Shanghai and analysis the polymorphism of the D4Z4 locus.

Methods: The length of D4Z4 repeats on chromosome 4q35 in 191 normal individuals in Shanghai was determined by pulsed-field gel electrophoresis and Southern blotting after double digestion with Eco RI and Bln I. The number of short D4Z4 repeats was counted after partial digestion with Kpn I.
