Summary: This study investigated the genomic diversity and relationships among seven different cattle breeds, showing shared ancestry and recent intermingling between breeds. Selection signatures revealed significant genetic differences between populations, with certain genes potentially affecting production traits and morphological characteristics in cattle. The presence of specific genes, such as HMGA2, may explain variations in stature among different breeds.

Summary: This study utilized whole genome resequencing and SNP markers to detect genetic linkage mapping and QTLs for ovary, fruit, and seed traits in melon. A total of 26 putative QTLs were identified across different chromosomes, with significant relationships and normal distribution frequencies observed in phenotype analysis. Further exploration and fine mapping of these QTLs could prove valuable in unexplored botanical groups of melon.

Summary: The study collected 120 samples of Derris trifoliata from three sites in Guangdong Province, China, and developed single nucleotide polymorphic markers using specific-locus amplified fragment sequencing technology. The analysis revealed medium genetic diversity levels and high clonal diversity in the populations, indicating the importance of sexual propagation in their succession. Additionally, an association analysis showed that nitrogen played a positive role in the formation and maintenance of the populations.

Summary: This study assessed the genetic diversity of Lutjanus kasmira populations in the South China Sea using SNP data obtained from RAD-seq. The results showed that the genetic diversity of the populations in Zhubi Dao and Meiji Dao was relatively low at the genome level, and their genetic differences were small.

Summary: This study evaluated the genetic diversity and population structure of 135 autotetraploid potatoes using SLAF-seq methods. Analysis of 3,397,137 high-quality SNPs revealed that the classification of these potatoes based on SNP profiles did not correlate with their geographical origins. Furthermore, 71 PARMS-SNP markers were successfully used to analyze 190 autotetraploid potato varieties. Overall, these novel SNP markers provide a solid foundation for potato genetic diversity analysis, DUS testing, and plant variety protection.

Summary: Hubei, Hunan, and Henan Provinces in Central China have extensive transport networks and trade. The spread of pine wilt nematode (PWN), the causative agent of pine wilt disease, is mainly due to human activities. Researchers studied the genetic structure of PWN populations in Central China and found significant variations among strains, with some genetically distinct strains closely related to Guangdong strains. The findings also suggest different transmission sources among strains in Henan province. This study provides insights into the origin and spread of pine wilt disease in China.

Summary: Italy has a diverse range of local chicken populations, including Val Platani (VPL) and Cornuta (COS), which are important genetic resources. This study used genotype data to investigate the genetic diversity, runs of homozygosity (ROH), population structure, and relationship of these populations. The results showed moderate genetic diversity in both populations, with ROH hotspots associated with immune response and adaptation to local temperatures. The population structure analysis revealed clear clustering based on geographic origin, with COS forming a distinct genomic cluster and VPL showing intermediate relationships with other Italian local chickens.

Summary: By constructing DNA fingerprints and analyzing the genetic structure of 259 melon varieties, it was found that Chinese melon varieties can be classified into five subgroups. The ssp. agrestis subgroup has a narrow genetic background and requires increased gene exchange with the ssp. melo subgroup. Core sets of markers were selected for efficient application in variety identification, monitoring, and intellectual property rights protection.

Summary: This study analyzed the whole-genome sequencing of B. abortus strains isolated in Kazakhstan and strains from various geographic origins. The results showed that the Kazakhstan strains were classified into subclades C1 and C2. The analysis also revealed clustering patterns between the Kazakhstan strains and strains from neighboring countries, as well as the dating of the introduction of subclade C1 into Kazakhstan.

Summary: This study analyzed the genetic diversity and population structure of 161 broccoli cultivars in China, revealing similarities in genetic backgrounds between foreign and domestic cultivars, but differences between domestic cultivars and Japanese cultivars. Population structure analysis showed that the 161 cultivars could be simplified into 1 simple group and 1 mixed group.

Summary: In this study, the genetic diversity of Coilia nasus was investigated using 2b-RAD simplified genome sequencing technology. The results showed that the genetic purity of the populations was low and needs to be improved. The populations exhibited high genetic diversity, indicating strong adaptability and potential for distribution and resource growth. Moderate genetic differentiation was observed among the populations, suggesting a common spawning ground for these migratory species and the need to protect the gene purity of C. nasus.
