Article Synopsis
  • The study focuses on the poplar hybrid 'P. xin lin 1', which grows quickly but is vulnerable to the herbivorous insect Hyphantria cunea, highlighting the need to understand its defense mechanisms at molecular levels.
  • Researchers analyzed the changes in gene expression and metabolite production in 'P. xin lin 1' leaves after being attacked by H. cunea at various time points, identifying 8925 differentially expressed genes and 842 metabolites.
  • Key findings reveal that several transcription factor families, particularly AP2/ERF, MYB, C2C2, and bHLH, are involved in the plant's defense, with significant pathways related to plant hormone

Background: As the methodological quality and evidence level of the existing systematic reviews (SRs) on music as an intervention for depression have not been thoroughly evaluated, a systematic evaluation and re-evaluation (SERE) was conducted.

Methods: Multiple databases including PubMed, Web of Science, Embase, China National Knowledge Infrastructure, SinoMed, Wanfang, and the VIP database were searched for SRs and meta-analyses (MAs) on the effectiveness of music as an intervention for depression. The literature screening, evaluation of methodological quality, and assessment of evidence level were carried out by a team of researchers.

The successful establishment of bark beetle-fungus symbionts on plants is required to overcome host defenses. However, little is known about how different bark beetle-fungus symbionts adapt to different niches on the same host plant. Here, we investigated the niche partitioning mechanism of two co-occurring bark beetle-fungus symbiotic systems, Ips nitidus-Ophiostoma bicolor and Dendroctonus micans-Endoconidiophora laricicola, on Qinghai spruce (Picea crassifolia) tree.

Worldwide, pine forests have been threatened by a devastating pine wood disease caused by Bursaphelenchus xylophilus, with Monochamus saltuarius being a newly recorded vector of the disease in Northeast China. The olfactory system plays important roles in both feeding and oviposition during the adult stage of M. saltuarius, and olfactory gene function research is essential for gaining an understanding of the olfactory mechanisms of this pest.

Background: Poplar in China has long been plagued by the fall webworm Hyphantria cunea. Enhancing plant immunity using chemical elicitors is an environmentally friendly approach to pest control. The phytohormone methyl jasmonate (MeJA) can stimulate the chemical defenses of poplars against herbivores but has been shown to have limited efficacy in practice.

Digital microfluidic biochips (DMFBs), which are used in various fields like DNA analysis, clinical diagnosis, and PCR testing, have made biochemical experiments more compact, efficient, and user-friendly than the previous methods. However, their reliability is often compromised by their inability to adapt to all kinds of errors. Errors in biochips can be categorized into two types: known errors, and unknown errors.

Background: Post-stroke depression (PSD) is a common complication following a stroke, significantly impacting patients' quality of life and mental well-being. Currently, two primary approaches are employed to treat PSD: drug therapy and non-drug therapy. Among these, acupuncture, specifically scalp acupuncture (SA), has gained attention due to its cost-effectiveness and broad social benefits.

When bark beetles invade and colonize the host plants, their associated pathogenic fungal partners are carried into the phloem of the host trees. Host trees are lethally attacked by the beetle-fungus complex and the collective damage severely limits forestry production worldwide. It is of great importance to verify whether bark beetles and their associated fungi show concordant performance in terms of biology, physiology, and biochemistry on host trees.

RNA interference (RNAi) technology is a promising approach used in pest control. The efficiency of RNAi varies considerably among different insect species, and growing evidence suggests that degradation of double-stranded RNA (dsRNA) prior to uptake is an important factor that limits RNAi efficiency in insects. Our recent work on fall webworm (), an important invasive pest in China, showed a relatively low silencing efficiency of RNAi through dsRNA injection, which is considered the most feasible dsRNA delivery method for inducing RNAi, and the factors involved in the mechanism remain unknown.

With the increasing demand for fast, accurate, and reliable biological sensor systems, miniaturized systems have been aimed at droplet-based sensor systems and have been promising. A micro-electrode dot array (MEDA) biochip, which is one kind of the miniaturized systems for biochemical protocols such as dispensing, dilutions, mixing, and so on, has become widespread due to enabling dynamical control of the droplets in microfluidic manipulations. In MEDA biochips, the electrowetting-on-dielectric (EWOD) technique stands out since it can actuate droplets with nano/picoliter volumes.

species (Lepidoptera, Lasiocampidae), are the most serious phytophagous pests of coniferous forests worldwide. feed intensively on needles, leading to considerable economic loss and ecological damage. Notably, the outbreak of is a somewhat periodic pattern, and those outbreaks cause rapid and large-scale destruction of pine forests, with those forests observed to look like "Fire without smoke".

Many bark beetles of the genus are economically important insect pests that cause severe damage to conifer forests worldwide. In this study, sequencing the mitochondrial genome and restriction site-associated DNA of bark beetles helps us understand their phylogenetic relationships, biogeographic history, and evolution of ecological traits (e.g.

In this work, we propose a method for estimating depth for an image of a monocular camera in order to avoid a collision for the autonomous flight of a drone. The highest flight speed of a drone is generally approximate 22.2 m/s, and long-distant depth information is crucial for autonomous flights since if the long-distance information is not available, the drone flying at high speeds is prone to collisions.

RNA interference (RNAi) is a widely used technique for gene function researches and recently pest controls. It had been applied in emerald ash borer (EAB ) larvae and adults, and achieved significant interference effects, whether by ingesting or microinjecting. Feeding in the phloem and cambial regions, the larvae of are difficult to be controlled by conventional insecticides, so adult stage is the critical stage for EAB control.

Chitinases, which are crucial enzymes required for chitin degradation and reconstruction, are often selectively considered to be effective molecular targets for pest control due to their critical roles in insect development. Although the chitinase gene has been reported previously, its sequence characteristics, gene function, and feasibility as a potential target for pest management were absent. In the present study, we characterized the chitinase gene and designated it .

The emerald ash borer (EAB), , is a highly destructive quarantine pest. The olfactory and visual systems of play different but critical roles at newly emerged and sexually mature stages; however, the molecular basis underlying these differences remain unclear. Consequently, based on deep transcriptome sequencing, we evaluated the expression levels of chemosensory-related proteins and opsins at the two developmental stages of .
