Pheromones play a pivotal role in chemical communication across various taxa, with protein-based pheromones being particularly significant in amphibian courtship and reproduction. In this study, we investigate the Emei music frog (Nidirana daunchina), which utilizes both acoustic and chemical signals for communication. Base on a de novo assembled genome of a male Emei music frog, we identify substantial expansion in four pheromone-related gene families associated with chemical communication.

Int J Mol Sci

December 2024

Key Laboratory of Livestock and Poultry Resources (Pig) Evaluation and Utilization, Ministry of Agriculture and Rural Affair, Yuelushan Laboratory, College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China.

In the context of modern pig farming, the central role of boars is underscored by large-scale centralized breeding and the widespread application of artificial insemination techniques. However, previous studies and breeding programs have focused mainly on product efficiency traits, such as growth rate, lean meat yield, and litter size, often neglecting boar semen traits. In this study, we estimated the genetic parameters and assessed the genomic prediction accuracy of boar semen traits with phenotypes evaluated from 274,332 ejections in a large population consisting of 2467 Duroc boars.

Tumor necrosis factor receptor-associated factor (TRAF) proteins, originally identified in mammals, have since been found in most plants. TRAF proteins in plants have been shown to be involved in cellular autophagy, immunity, drought resistance, and ABA induction. However, the role in regulating sucrose and starch metabolism has not been reported.

Precise acquisition of potted plant traits has great theoretical significance and practical value for variety selection and guiding scientific cultivation practices. Although phenotypic analysis using two dimensional(2D) digital images is simple and efficient, leaf occlusion reduces the available phenotype information. To address the current challenge of acquiring sufficient non-destructive information from living potted plants, we proposed a three dimensional (3D) phenotyping pipeline that combines neural radiation field reconstruction with path analysis.

Arbuscular Mycorrhizal Fungi-Assisted Phytoremediation: A Promising Strategy for Cadmium-Contaminated Soils.

Plants (Basel)

November 2024

Guangdong Engineering and Technology Center for Environmental Pollution Prevention and Control in Agricultural Producing Areas, College of Resources and Environment, Zhongkai University of Agriculture and Engineering, Guangzhou 510225, China.

Arbuscular mycorrhizal fungi (AMF) have been shown to play a major role in regulating the accumulation, transport, and toxicity of cadmium (Cd) in plant tissues. This review aims to highlight the current understanding of the mechanisms by which AMF alleviate Cd toxicity in plants. Cd accumulation in agricultural soils has become an increasing global concern due to industrial activities and the use of phosphatic fertilizers.

The storage period of paddy is a critical factor affecting rice quality, and it is still unclear how fresh rice noodles, primarily made from paddy, respond to changes in the storage period. To elucidate the relationship between the paddy storage period and the quality of fresh rice noodles, this study used fourteen rice varieties as materials and set up three paddy storage periods (six months, nine months, and twelve months). It explored the quality variation patterns of fresh rice noodles processed from these paddies and analyzed the relationship between the two in conjunction with rice quality.

In order to elucidate the development of quality properties in the fat portion of Chinese bacon during low-temperature smoking (LTS), raw pork was cured for five days, followed by infusion with smoked liquid and a subsequent ten-day smoking period characterized by alternating high and low-temperature conditions. The physicochemical characteristics and microstructures of the fat portion of the Chinese bacon were examined at three stages: the raw meat stage (Control), the curing stage (C3d and C5d), and the smoking stage (S5d and S10d). The results showed that LTS increased the hardness, transparency, and b* value of bacon fat.

Egg Protein Compositions over Embryonic Development in Ticks.

Animals (Basel)

November 2024

College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China.

Tick eggs contain a series of proteins that play important roles in egg development. A thorough characterization of egg protein expression throughout development is essential for understanding tick embryogenesis and for screening candidate molecules to develop novel interventions. In this study, eggs at four developmental stages (0, 7, 14, and 21 incubation days) were collected, and their protein extraction was profiled using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE).

Two-dimensional lead-halide perovskites provide a more robust alternative to three-dimensional perovskites in solar energy and optoelectronic applications due to increased chemical stability afforded by interlayer ligands. At the same time, the ligands create barriers for interlayer charge transport, reducing device performance. Using a recently developed ab initio simulation methodology, we demonstrate that ligand fluorination can enhance both hole and electron mobility by 1-2 orders of magnitude.

Article Synopsis
  • Surface sterilization of fertile eggs with 70% ethanol is commonly used in broiler breeding to prevent infections, but it can also eliminate beneficial microbes that aid embryo development.
  • A study was conducted with 460 Ross 308 fertile eggs divided into sterilized and unsterilized groups to assess the effects of this sterilization on the yolk microbiota and embryo growth.
  • Results indicated that while sterilization improved embryo development from E15 to E21, it also decreased the diversity of the yolk microbiota, resulting in lower levels of beneficial bacteria but fewer pathogens.

In recent years, "black swan" events have increasingly occurred across climate, epidemics, geopolitics, and economics, leading to a gradual coupling of different types of risk. Different from isolated shocks as a single type of risk affecting a specific industry, a nexus of risks allows one risk area to quickly relate to others, resulting in more catastrophic impacts. Utilizing an integrated framework, we investigate the contagion effects among climate policy uncertainty, the infectious disease equity market volatility tracker, geopolitical risk, and economic policy uncertainty using volatility, skewness, and kurtosis as risk measures.
