Zanthoxylum planispinum is a type of plant with homologous properties in medicine and food, making it well-loved in China. To explore the development of the Z. planispinum field over the past 20 years, its research hotspots and frontier trends were analyzed. This study conducted database-based visualization analyses and knowledge graph analyses using CiteSpace software with data concerning Z. planispinum published in the Chinese National Knowledge Infrastructure and Web of Science databases between 2003 and 2023. Over the last 20 years, the number of Chinese and English publications on Z. planispinum has shown increasing trends. The foci of this research were mainly germplasm resources, cultivation management, seed oil extraction technology, flavonoid extraction technology, and correlation analyses of antioxidant activities. The main research frontiers included the unified standard naming and adaptation mechanisms of Z. germplasm resources, orientation cultivation, functional component extraction, processing technology research and development, and industrial chain construction. The results provide a scientific reference for the high-quality development of the Z. planispinum industry. [ABSTRACT FROM AUTHOR]

In this study, the complete mitochondrial DNA of the hybrid of Simmental and Qinghai local cattle breed was sequenced and analyzed. The total mitochondrial genome sequence is 16,339 bp in length including 1 control region (D-loop), 22 tRNA genes, 2 rRNA genes and 13 protein-coding genes. The description of all genes is similar to the typical mitochondrial genomes of cattle. All the protein-coding genes were located on the heavy strand (H strand) except forND6. TheCOX3, ND3, andND4genes own incomplete stop codon. [ABSTRACT FROM AUTHOR]
