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: 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: 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: Sickleweed (Falcaria vulgaris) is significant for its nutritional value and medicinal effects. In this study, 15 Sickleweed populations were analyzed for genetic diversity using morphological traits, bioclimatic parameters, and SCoT markers. The results showed significant differences between populations for the studied traits, and clustering analysis divided the populations into two groups based on morphological traits. The SCoT markers produced polymorphic bands and cluster analysis based on molecular data further grouped the populations into three groups. This study highlights the high genetic diversity of Sickleweed populations and provides insights for breeding and management practices.
