Hence, this study conducted high-throughput whole genome resequencing on 47 Chinese bayberry germplasm resources in Southern Zhejiang with single nucleotide polymorphism (SNP) and Insertion Deletion (InDel) markers used to analyze the population genetic structure, evolutionary relationships, phylogenetic relationships, and genetic diversity. The results revealed that the quantity of clean reads mapped to the reference genome accounted for 96.53% of the total, and a total of 5,380,296 variant sites were detected, including 4,667,304 SNP variant sites and 712,992 InDel variant sites. According to the genetic structure and principal component analysis, the 47 Chinese bayberry samples were clustered into 3 groups, among which, group1(G1) included 10 resources, mainly consisting of large-fruited and late-maturing Chinese bayberry introduced from external regions. It was closely aggregated with each other and had small genetic difference in G1. Group2(G2) included 17 resources, mainly consisting of local cultivars with early maturity and medium-sized fruits, with large genetic differences and rich diversity. Group3(G3) included 20 resources which grew from direct germination of seeds to adult fruiting trees, exhibiting complex genetic backgrounds and significant differences. The genetic distance of the 47 Chinese bayberry samples ranged from 0.024 to 0.332, with an average genetic distance of 0.241. The average value of the diversity index (<i>He</i>) was 0.3, and the average value of the polymorphism information content (<i>PIC</i>) was 0.244. In the genetic evolution analysis, G2 and G3 were further divided into 5 subgroups and 6 subgroups, respectively, both demonstrating a relatively high genetic diversity. In summary, the genetic background of the 47 Chinese bayberry resources is rich, their genetic evolutionary relationship is relatively independent and complex, and their genetic diversity is high. This conclusion could further broaden the genetic distance between parents, and provide materials and theoretical guidance for the subsequent selection of parents and screening of excellent cultivars in Chinese bayberry breeding.</p>","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":"4 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its potential has not been fully exploited through breeding because of the limited understanding of genetic variation in oil-related traits. The present study characterized the genetic diversity of 386 <i>B. carinata</i> accessions to identify superior genotypes based on their oil content and fatty acid composition. The experiment employed an augmented block design with two replicates. Oil content and fatty acid profiles were determined using nuclear magnetic resonance spectroscopy (NMRS) and near-infrared reflectance spectroscopy (NIRS), respectively. Significant (<i>p</i> ≤ 0.05) variation was observed across all traits, with seed oil content ranging from 37.88% to 46.98%. High heritability (85–94%) and genetic advance (22.30–59.29%) were estimated for all traits. Cluster analysis revealed seven distinct groups with significant intercluster distances. Generally, acc-386 for oil content, acc-02 for erucic acid, acc-386 for α-linolenic acid, acc-385 for eicosenoic acid, and acc-309 for stearic acid were identified as promising candidates for industrial applications because of their high oil content and fatty acid levels. Acc-372 for linoleic, acc-326 for oleic, and acc-270 for palmitic acids showed considerable potential for further improvement for edible oil.

Therefore, understanding the role of seed priming through the application of hydropriming and nanopriming using silver nanoparticles (AgNPs) is highly important in response to drought stress. This study aims to detect the natural phenotypic variation of the traits related to germination parameters, seedling characteristics, and seed biomass, as well as the chlorophyll content under both control and drought treatments. Evaluating wheat accessions response to seed priming, including hydropriming and nanopriming using 50 ppm AgNPs. Under drought stress, a highly significant increase was detected for germination-related traits, seedling, and biomass parameters in wheat seeds exposed to silver nanopriming as compared to the control treatment. Under nano-primed seed (AgNPs) conditions, root length showed a positive correlation with all traits under drought stress, suggesting a strong relationship between root length and all germination and seedling parameters resulting in wheat experiencing tolerance to water shortage conditions. Based on genome wide association study (GWAS) and linkage disequilibrium (LD) outputs, a total of 261 single nucleotide polymorphism (SNP) markers were detected for all of the studied traits under both control and drought conditions. Interestingly, twenty reliable genomic regions with several hotspots of significant SNP markers were discovered inside high LD regions.
