Despite being widely available across the nation and utilized for a variety of purposes for centuries, little is known about the degree of genetic variability in sweet basil.

The observed and expected heterozygosis are (0.01–0.02) and (0.13–0.33), respectively. The gene diversity index (GD) ranged from 0.13 to 0.29, with an overall mean of 0.13. Moreover, the polymorphic information content (PIC) varied from 0.23 to 0.37, with an average of 0.37. The Shannon index (I) ranged from 0.01 to 0.41, with an average of 0.12. A total variation of 90 % and 1 % within and among populations, respectively, was revealed using analysis of molecular variance (AMOVA). Furthermore, genetic variation showed a coefficient of gene differentiation of 0.01 and a gene flow value of 2.013 among populations. The 62 basil accessions were divided into two genetic groups according to STRUCTURE analysis, unweighted pair group method (UPGMA), discriminant analysis of principal components (DAPC), and principal coordinate analysis (PCoA). This research confirmed the diversity and population structure of the Ethiopian basil.

However, the emergence of new virulent strains of Pst, driven by continuous mutations within the pathogen, rapidly undermines the effectiveness of existing resistance genes. This necessitates the ongoing identification and incorporation of new resistance genes to breed wheat varieties that can maintain resistance against evolving strains of the pathogen. A genome-wide association study (GWAS) and genomic prediction (GP) were conducted using yellow rust data from the seedling stage under controlled conditions, involving 200 elite bread wheat genotypes and 13,151 SNP markers.

Highly migratory shark species exhibit varying levels of fidelity to specific regions, shaping the genetic architecture of different populations and resulting in geographically based genetic variation with potential adaptive value. An understanding of the genetic variation of highly migratory species is needed to develop effective conservation strategies. This study aimed to assess the neutral and adaptive variation of the smooth hammerhead shark (Sphyrna zygaena) in the northern Mexican Pacific (NMP) via single nucleotide polymorphisms (SNPs). We analyzed 1480 SNPs in 92 individuals from four geographic regions in the NMP, of which 1469 SNPs were neutral loci (n-SNP), and 11 were putatively under selection (o-SNP) using four genoma scan methods. Genetic diversity was geographically similar among regions (Ho = 0.275). The neutral variation showed panmixia (n-SNPs; FST = 0.0012, p = 0.44), which may be associated with the high dispersal capacity of S. zygaena. A pattern of adaptive variation between individuals from the Gulf of California and Pacific coast was revealed using o-SNPs FST-based methods (24 oSNPs; FST = 0.061, p < 0.001), which may be promoted by individual preferences based on physiological limitations.

The data were analyzed using the genotype by yield*trait (GYT) biplot method, and the superiority index was calculated from the integration of all yield-trait combinations.

Therefore, they can be considered in genetic biofortification programs or variety introduction.</div>","PeriodicalId":37938,"journal":{"name":"Ecological Genetics and Genomics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139738744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
