Article Synopsis
  • The ABC1K atypical protein kinase family plays a key role in regulating plant growth, development, and stress responses but has been under-researched in alfalfa.
  • In this study, 22 ABC1K genes from the alfalfa genome were identified and categorized based on genetic analysis, revealing their physical, biochemical, and expression characteristics.
  • The findings suggest that these genes are vital for alfalfa’s response to abiotic stress factors like salt and drought, providing a foundation for improving stress resistance in this plant species.

Lepidopteran insects are a major threat to global agriculture, causing significant crop losses and economic damage. Traditional pest control methods are becoming less effective due to the rapid evolution of insecticide resistance. This study explores the current status and genomic characteristics of 1315 Lepidopteran records, alongside an overview of relevant research, utilizing advanced functional genomics techniques, including RNA-seq and CRISPR/Cas9 gene-editing technologies to uncover the molecular mechanisms underlying insecticide resistance.

Article Synopsis
  • Syrian rue, a plant found in arid regions of China, is crucial for soil conservation and stabilization against sand encroachment and plays a key role in reclaiming wastelands.
  • In 2023, a disease resembling root rot affected about 50% of Syrian rue plants in Inner Mongolia, causing symptoms like yellowing, wilting, and darkening of the roots' xylem.
  • Researchers collected symptomatic samples, isolated a pathogen (designated LTP-5), and observed specific morphological characteristics of the fungal colonies grown in the lab, indicating its potential impact on Syrian rue's health and agricultural yield.

Article Synopsis
  • Grasslands are essential ecosystems that provide valuable services to humans and the environment, marked by their diverse plant life, healthy soil, and vibrant microbial communities.
  • These ecosystems face threats from overgrazing, agricultural land conversion, climate change, and notably, rodent activities, which can either positively or negatively influence grassland health depending on their population density.
  • The review highlights the complex relationship between rodent activities and grassland degradation, discusses methods to mitigate their negative impacts, and calls for more research to fully understand how rodents shape these vital ecosystems.

Plants communicate with insects and other organisms through the release of volatile organic compounds (VOCs). Using Boolean operators, we retrieved 1093 articles from the Web of Science and Scopus databases, selecting 406 for detailed analysis, with approximately 50% focusing on herbivore-induced plant volatiles (HIPVs). This review examines the roles of VOCs in direct and indirect plant defense mechanisms and their influence on complex communication networks within ecosystems.

Grasshoppers pose a significant threat to both natural grassland vegetation and crops. Therefore, comprehending the relationship between environmental factors and grasshopper occurrence is of paramount importance. This study integrated machine learning models (Maxent) using the kuenm package to screen MaxEnt models for grasshopper species selection, while simultaneously fitting remote sensing data of major grasshopper breeding areas in Inner Mongolia, China.

Article Synopsis
  • Weeds negatively impact crop health and yield, making the study of microorganisms for weed control increasingly important.
  • In a controlled experiment, researchers used advanced techniques to examine hormone effects and gene expression related to plant growth in the presence of an oil-producing fungus.
  • The findings revealed that this fungus significantly stunted plant growth and altered gene expression, particularly affecting the metabolism of phenylalanine and tryptophan, ultimately inhibiting plant development.

Rodents are essential to the balance of the grassland ecosystem, but their population outbreak can cause major economic and ecological damage. Rodent monitoring is crucial for its scientific management, but traditional methods heavily depend on manual labor and are difficult to be carried out on a large scale. In this study, we used UAS to collect high-resolution RGB images of steppes in Inner Mongolia, China in the spring, and used various object detection algorithms to identify the holes of Brandt's vole ().

Lepidopteran insects mainly rely on sex pheromones to complete sexual communications. Pheromone receptors (PRs) are expressed on the olfactory receptor neurons (ORNs) of the sensilla trichodea and play an essential role in sexual communication. Despite extensive investigations into the mechanisms of peripheral recognition of sex pheromones in Lepidoptera, knowledge about these mechanisms in remains limited.
